Evaluation of Ectiban Formulations For Fly Control on Cattle U C Sierra Foothill Range Field Station California 1981

E C Loomis PhD Parasitologist Lorry L Dunning Staff Research Associate

Extension Veterinary Medicine University of California Davis 95616

INTRODUCTION

Sixty (60)- Hereford heifers (avg wt4Q0 lbs) maintained on irrigated pasture at the U C Field Station were used for a fly control trial using Ectiban Pour~On and~Ectiban insecticide Ear Tag Tapes The heifers were divided into 6 equal groups of 10 each and were identified as groups 1 to 6 Twenty-five heifers of similar age and weight were kept on dry rangeland about 12 mile distant and served as Group 7 for a control (untreated) All 85 heifers were rated for horn fly densities in corrals prior to group separation and treatment but face fly counts were made in the field one week later

MATERIALS AND PROCEDURES

Ectiban formulations for trial evaluation consisted of a ready-to-use 1 Permethrin Pour-On (GFU003 Red 6766 dated 32481) and I-gram active ingredient Permethrin Ear Tag tapes for application to cattle ear tags These formulations were compared to a standard registered 005 spray using Coopertox Extra (Toxaphene 45 Lindane 196gt

Ectiban Pour-On was applied by means of 4 oz capacity metal dippers to 4 groups at a dosage of 12 ozcwt initially on June 10 and retreated on August 3 Groups 1 and 4 received a backline application while groups 2 and 5 received a face and poll application Groups 3 and 6 were sprayed over the entire body on June 10 and only Group 6 W4S resprayed on September 30 using 12 gallon (70 ozgt of Coopertox solution per head from a U C power sprayer equipped with a 6 HP Briggs amp Stratton engine plus by-pass pump system operated at 300 psi

Ectiban Ear Tag tapes for ear tag application arrived midway through the trial and some of the groups were split for tape application when retreatment was indicated on September 2 Groups 2 and 3 received one tape per heifer attached around the neck of the ear tag and Group I had a tape wrapped around the _end of the tail (above the switch) and secured with adhesive duct tape Groups 4 to 6 were not retreated at this time in order to determine possible effects of fly control from Ectiban-taped heifers which shared common fence lines and

2

exposure with the 3 Groups Following observations on September 23 it was decided to retreat Groups 4 to 6 on September 30 using the same Pour-On and Spray regimen as applied at the start of the trial

Visual fly counts by eye or with the aid of 7 x 50 binoculars were made in most cases by one observer on all 10 heifers in each of 6 Groups and on 10 of the 25 heifers in control Group 7 Counts were made from lOAM to 2PM at weekly intervals Horn fly counts (H irritans) were made on flies resting on one side of the body (withers ribcage and upper legs) and on Face flies (M autumnalis) resting on the face and head area

O~e way analysis of variance was used to determine if overall trea-tment means varied significantly Fishers LSD method was used to compare where differences occurred between treatment means

RESULTS AND DISCUSSION

The results on Horn fly control are shown in Table 1 Excellent control was obtained for 4 weeks (June 10 to July 7) for Ectiban backline Pour-On to Groups 1 and 4 while excellent to good control resulted from Ectiban face Pour-on on Groups 2 and 5 for the same 4 weeks Coopertox spray on Groups 3 and 6 provided excellent control for only 2 weeks (June 10 to 24) Surprisingly retreatment of the 4 Ectiban groups on August 2 provided not more than 2 weeks of satisfactory control Of equal interest was the dramatic decrease in horn flies for two weeks on Group 3 but only slightly so on Group 6 both of which were intentionally not resprayed with Coopertox on August 2 There was no significant difference between Ectiban Pour-On to the backline or to the face nor between these treatments and the Coopertox body spray as determined from mean totals on Horn fly populations for the entire trial period June 10 to October 17 all three treatments reduced horn flies significantly better (P lt 0005) than the control (Table 3)

Also included in Table 1 are the results for horn fly control following Ectiban Tape applications on September 2 Excellent control resulted for 4 weeks on taped-heifers in Groups 1 2 and 3 No significant difference occurred between tape treatments to the ear or tail but all 3 treatment groups showed significant fly reduction (P lt 0005) when compared to the control group (Table 4) Fly populations in control Group 7 decreased rapidly with the onset of cold nights during the week of October 10

The results on Face fly control are shown in Table 2 Relatively good control of this species occurred with the Pour-On treatments for about 2 weeks (June 10 to 24) -with almost similar results for the Coopertox spray Fly control on these same groups retreated on August 3 provided a shorter

period of control about 9 to 1i days the natural dccro(1s(~ in Face fly popula tion s dur i ng Ju 1 and Augus t as ev idenct~d in Control Group 7 is commonplace and fly numbers are too low to warrant reliable comparison witn treated animals There was no significant difference between the Ectiban Pour-On to the face or to the backlinebut both treatments -were significantly different (P lt 0005) than the Coopertox spray and the control (Table 3)

Also included in Table 2 are the results for Face fly control following Ectiban tape applications on September 2 Excellent (Group 2) to good (Group 3) control resulted one day after application with tapes applied to ear tags but control did not persist at a satisfactory level as evidenced by the increase in fly counts on September 9 there was poor control via tapes attached to the tail (Group 1) The poor significance of these results are shown in Table 4 Poor results were obtained on face fly ~ontrol upon retreatment of Groups 41 and 50n September 30 and similar JesuIts were evident on Group 6 which was resprayed wi th Co_opertlt~

Of interest in this trial were the results on Horn fly control from the small amount of Ectiban Pour-On to the face of animals Heretofore it was believed that a similar dose of a pesticide to the withers was more effective but if Face fly populations are the main target then face and head applications could serve a dual purpose to include Horn fly control

Early IrrIgation - Liquid Supplement Trial

RIck Delmas

This study was initiated In 1980 to study the performance of

cattle using liquid supplement and the effect of early irrigation of

annual grasslands for early fall growth on the performance of cattle

during the fall and winter grazing period

Though the trial needs to be continued for the next couple of

years the following are indicated from one years data

1) Early irrigation furnishes valuable early fall feed especially

in poor rainfall years

2) Liquid supplement doesnt appear to be as beneficial as concentrates

for young cattle during the fall and winter The conception rate

on cattle with only liquid supplement was 8 to 19 lower than on

the other three treatments Economically the liquid supplement

was half the cost or less of the concentrate excluding labor

From this sfandpoint alone a rancher may be wIlling to accept

a slightly lower conception rate to obtain the decreased labor

and supplement cost Each individual rancher must measure cost

versus production

1981 was the sixteenth year that forage production has been measured in this study I have considered terminating the measurements because yield increases have not been significant in three of the last four years (see table) However data show that increases were significant in all of the sixteen years in which forage production on the check treatment (area covered by live trees) was below the median of the period (1385 Ibacre) Therefore in the interest of economy only the check treatments will be sampled in high rainfall years If another poor feed year occurs soon we will measure all treatments

6 Progress Report (Progress uring report perio toward reaching objectives of this research) The Ecologv and Population Dynamics of Aphodius fimetarius

The ecological study of the dung beetle Aphodius fimetarius was continued by again monitoring the ability of males and females to hibshyernate (aestivate) from late Spring to Fall From May 29 through June 9 we collected and marked 3020 beetles with fluorescent dust Half of these were released into a beetle-proof screened field cage in the Scott 14 pasture and the other half were released into a s~milar cage at the Howarth pasture o Both cages enclosed about 30 ft of natural turf and each was supplied with fresh dung (beetle food) until no beetles were present These two cages were monitored for the re-eppearance of beetles from September through December and cattle droppings from various pastures were sampled for the presence of naturally appearing wild beetles

During the past year the first beetles appeared in pasture droppings on November 4 when the dung peds had an average of 27 beetlespad On different weeks from November 11 through December 11 the density of ~ fimetarius remained fairly stable at 29 21 23 end 25 beetlespad As in previous years the beetle density then began to decline with 15pad on December 15 and less than one per pad on January 7 1982 In the Fall of 1981 beetles that had been marked and released into the experimental cages first appeared in the Scott 14 pasture on November 9 5 days after beetles first appeared in cattle dung pads in pastures The marked beetles contshyinued to appear in the Scott 14 cage through December with one beetle last appearing on December 16 No beetles were recovered in the Howarth pasture cage and through December 16 only 1 of marked beetles had been recovered in the Scott 14 cage This is in marked contrast to the cage recapture rates of 57 in the Scott pasture and 104 in the Howarth pasture It appears that beetles marked with the fluorescent dust suffershyed heavy mortality most of the marked beetles recovered had only a few particles of dust under the elytra or under the membraneous wings Nevertheless recapture of marked beetles confirmed that ~ fimetarius naturally hibernates (aestivates) in the ground for about 5 months in this part of California Other methods of marking beetles will be tested during the next seaSon

The objectives of this research were outlined in the 1980 report Many of the same trends observed in 1980 were repeated in 1981 Body weights of the cows were positively related to level of supplementation

(Table 1) The greatest effect was observed at the start of the breeding season where the difference between the unsupplemented and 25 times supplemented cows was nearly 100 kg

Weaning weight of the calves (Table 2) reflected the plane of nutrition of the cows Although weaning weights were enhanced by supplementation the largest differences in body weights occurred at the times the dams were mated Body weights of the calves reflected differential milk production of the cows

As in the previous year birth weight of the calves was not affected by plane of nutrition of the cows

6 Progress Report (Progress during report period toward reaching objectives of this research)

The major objectives of this research with Hereford cattle are (1) to determine if individual differences in mounting frequency by juvenile males correlate with individual differences in sexual motivation and performance as adults (2) to determine the degree of correlation between sexual behaviors and other biological traits (eg aggressive behavior semen characteristics hormone levels body size scrotal circumference) (3) to determine the function of mounting exshyperience on the development of sexual behavior and (4) to determine the role of penile stimulation on the development of sexual behavior

Over the last 4 years 78 bulls have been obtained from the SFRFS herd to investigate these questions Twenty-four male calves were brought to Davis from SFRFS in May 1981 to be used in studying objective 114 No observations were made on this group at the Field Station

Prior to 1981 all of our observations on juvenile mounting (Objectives 1 and 3) were made in confined situations where estrous heifers were provided as mountingstimuli and inter-animal contacts were frequent To determine the frequency of juvenile mounting in a more typical range environment 10 male and 9 female purebredHereford calves were observed between January 13 and March 22 1981 for a total of 40 hrs (29 different days) The calves ranged in age from 48 to 102 days (x = 80 days) at the start of observation A total of 394 calf observation hours were made on the 10 bull calves in the group and 749 calf hours on all 19 calves

Relative to our studies in confinement the rate of juvenile mounting in a typical range environment is very low A total of 15 mount intentions 12 mount attempts and 6 mounts (33 mount responses) were observed during the 40 hrs of observation Except for one mount intention all of the mounting activities were exhibited by bull calves The rate of mount responses was 0084 per bull calf per hour of observation Nearly all of the mounting behaviors were observed near the feed trough following feeding of supplements Supplemental feeding was terminated on February 25th and no sexual activity was observed among calves after that date

It was concluded that the mounting experience of 2-12 to 4-12 mo juvenilecalves in a ranqe environment is very limited

promising at present arc Monterey pine coast redwood and varieties of Pinus halepensis (brutia and eldarica) The most promising hardwoods to date are Eucalyptus globulus camaldulensis (2 variants) urnigera and grandis

In the lower Plot near the Yuba River deer and cattle damage al1d some porcupine debarking have greatly reduced the choice of species here The above pines Arizona cypress plus possibly tamarisk aphylla and coast redwood still appear promising

The North Plot after 3 years of trial plantings versus 4 for the other plots shows promising results for only Arizona cypress Eucalyptus grandis from 2 sources and tamarisk aphylla It is too early to rate the remainj~g species over-all survival rates of which are generally low

No fertilizer tablets have been applied to any of these plots because other factors limiting growth and survival appear more Important There was no serious rodent or insect damage noted in any of the 3 plots this past year and irrigation practices have been generally good probably supplying around 3 acre feet per growing season of about 6 months

It is now planned to establish semi-commercial plots of a minimum of 112 acre for each of at least 5 of the most promising species in another area of the Sierra Field Station

Development work continued in the Campbell Field A fall-1980 seeding of a perennia grass-legume pasture mixture on the new irrigated pasture areas was successful except for parts of some fields where irrigation water (surface flow) failed to reach In general the newly-installed irrigation system performed well

The following work was done on or related to the range fertilization study being conducted on the Forbes Flll44 series fields

a Soil samples were taken from each of the 16 fields Analyses will be made for P 5 Ca Mg K and pH

b In cooperation with M B Jones (HFS) field plots were established at eight locations (4 north-facing aspects 4 south-facing) A factorial design was used to compare 4 levels of N (as urea) and 4 levels of P (as low-S concentrated superphosphate) plus an exploratory for several combinations of NPS with two replications at each locati r

c Also in cooperation with M B Jones a greenhouse pot test was set up at the Hopland Field station with rate-element combinations to match those in the field plots using soil collected at the field locations for the eight replications The pots were seeded with a mixture of sub and rose clovers together with soft chess

d M R George and W J Clawson located sites for a grazing utilization study employing 10 x 10 exclosures

e A field-scale experiment with aerial application of nitrogen (as urea) at 0 40 80 and 120 kgha rates (two fields per replication two replications per treatment) is planned for fall 1982 following evaluation of the tests described above and results of a pre-experiment calibration grazing (with steers) beginning February 1982 Roy Hull J G Morris and R E Delmas are cooperators from the Department of Animal Science

6 Progress Report (Progress during report period toward reaching objectives of this research)

Four pairs of 14 acre plots were established during the fall of 1979 The Blue Oak overstory of these paired plots was approximately 0 25 50 and 75 The tree overstory was removed from one set of four plots by February 15 1980 and 12 wire mesh igloo type cages were placed on all plots by December 1980 Cages were located under tree canopy (or former tree canopy) and in the open using a stratified random procedure with proportional allocation

During 1981 three successive clippings were taken from inside the wire cages to determine the total standing crop present on February 21 (early season) April 3 amp 4 (mid-season) and June 2 (late season)

Preliminary Results (1981)

Uncleared plots 25 50 and 75 overstory cover Standing crop at any season did not differ appreciably by overstory level (Fig 1) When compared with uncleared open (0 overstory cover) plots standing crop was significantly less in uncleared plots at late season but not at early and mid-season Overstory cover and standing crop are not significantly correlated for any season (Fig 2)

Cleared Plots 25 50 and 75 prior overstory cover Standing crop is positively correlated with prior overstory cover particularly when uncleared open (0 overstory cover) plots are included in the comparison (Fig 2)

Tree removal greatly increased standing crop at all three seasons of harvest for all overstory cover levels (Fig 1) When compared to uncleared plots of the same overstory cover level these increases were 100 early season 133 midshyseason and 80 late season

Data collected on mothers included frequency and duration of licking (grooming) calves vocalizattons butts and butt attempts directed at alien calves and behavioral responses to separatton from calf(ves) Calves were observed for frequency and duration of sucking on own and aUen mothers frequency and duration of resting runn1ng laying and grazing frequency of vocalizations and juvenilemounting and prox1m1ty to mother tw1n and nea~est unrelated calf

The data have been compiled but have not yet been analyzed statistically

6 Progress Report (Progress during report period toward reaching objectives of this research)

This experiment was undertaken to assess the efficacy and safety of a salt selenium mixture for supplementing range cows

Approximately a years data have been obtained on two groups each of 19 mature Hereford cows grazing range and offered two salt-selenium mineral mixtures free choice The concentration of selenium in one mixture was 40 ppm (low Se group) and the other 80 ppm (high Se group) These levels represent 2 and 4 times the maximal level currently permitted by FDA

Blood selenium concentrations (Figure 1) were determined on each animal at weekly intervals initially then at monthy intervals Intake of the salt-selenium mixture was also measured at monthly intervals to obtain total group mean intake of selenium

Blood selenium concentration rose from the initial concentration of 0035 ~gml to a maxima of approximately 0225 ~gm1 in the high group and 0150 ~gm1 in the low group at about 12 weeks Then maximal concentrations are within the range of normality and in no way indicate selenium toxicity

Intake of the salt-selenium mixture was not well correlated with blood concentration of se1eniUffl

Then data indicate that the FDA maximal level of 20 ppm selenium in salt supplements is conservative and may be ineffectual in areas of selenium deficiency There was no significant difference in the weight of the cows at the time the calves were weaned - low group 487 ~ 48 kg high group - 481 ~ 57 kg

SlJotMARY OF COMMENTS

The foothills of California offer an ideal place for people

to pursue farming Farming in the tradi tional sense family cerltered

labor interlsive small machinery oriented conservation minded small

Hopefully the U C Sierra Foothill Range Field Station will accept

and meet the challenge of providing research and information appropriate

to the fledgling development of a foothill agriculture ethic in which

the quality of food and living is paramount Projects of this nature

are few in the 1981 annual report Possibly we can make II greeter

contribution to foothill farming in the future

Evaluation of Ectiban Formulations For Fly Control on Cattle U C Sierra Foothill Range Field Station California 1981

E C Loomis PhD Parasitologist Lorry L Dunning Staff Research Associate

Extension Veterinary Medicine University of California Davis 95616

INTRODUCTION

Sixty (60)- Hereford heifers (avg wt4Q0 lbs) maintained on irrigated pasture at the U C Field Station were used for a fly control trial using Ectiban Pour~On and~Ectiban insecticide Ear Tag Tapes The heifers were divided into 6 equal groups of 10 each and were identified as groups 1 to 6 Twenty-five heifers of similar age and weight were kept on dry rangeland about 12 mile distant and served as Group 7 for a control (untreated) All 85 heifers were rated for horn fly densities in corrals prior to group separation and treatment but face fly counts were made in the field one week later

MATERIALS AND PROCEDURES

Ectiban formulations for trial evaluation consisted of a ready-to-use 1 Permethrin Pour-On (GFU003 Red 6766 dated 32481) and I-gram active ingredient Permethrin Ear Tag tapes for application to cattle ear tags These formulations were compared to a standard registered 005 spray using Coopertox Extra (Toxaphene 45 Lindane 196gt

Ectiban Pour-On was applied by means of 4 oz capacity metal dippers to 4 groups at a dosage of 12 ozcwt initially on June 10 and retreated on August 3 Groups 1 and 4 received a backline application while groups 2 and 5 received a face and poll application Groups 3 and 6 were sprayed over the entire body on June 10 and only Group 6 W4S resprayed on September 30 using 12 gallon (70 ozgt of Coopertox solution per head from a U C power sprayer equipped with a 6 HP Briggs amp Stratton engine plus by-pass pump system operated at 300 psi

Ectiban Ear Tag tapes for ear tag application arrived midway through the trial and some of the groups were split for tape application when retreatment was indicated on September 2 Groups 2 and 3 received one tape per heifer attached around the neck of the ear tag and Group I had a tape wrapped around the _end of the tail (above the switch) and secured with adhesive duct tape Groups 4 to 6 were not retreated at this time in order to determine possible effects of fly control from Ectiban-taped heifers which shared common fence lines and

2

exposure with the 3 Groups Following observations on September 23 it was decided to retreat Groups 4 to 6 on September 30 using the same Pour-On and Spray regimen as applied at the start of the trial

Visual fly counts by eye or with the aid of 7 x 50 binoculars were made in most cases by one observer on all 10 heifers in each of 6 Groups and on 10 of the 25 heifers in control Group 7 Counts were made from lOAM to 2PM at weekly intervals Horn fly counts (H irritans) were made on flies resting on one side of the body (withers ribcage and upper legs) and on Face flies (M autumnalis) resting on the face and head area

O~e way analysis of variance was used to determine if overall trea-tment means varied significantly Fishers LSD method was used to compare where differences occurred between treatment means

RESULTS AND DISCUSSION

The results on Horn fly control are shown in Table 1 Excellent control was obtained for 4 weeks (June 10 to July 7) for Ectiban backline Pour-On to Groups 1 and 4 while excellent to good control resulted from Ectiban face Pour-on on Groups 2 and 5 for the same 4 weeks Coopertox spray on Groups 3 and 6 provided excellent control for only 2 weeks (June 10 to 24) Surprisingly retreatment of the 4 Ectiban groups on August 2 provided not more than 2 weeks of satisfactory control Of equal interest was the dramatic decrease in horn flies for two weeks on Group 3 but only slightly so on Group 6 both of which were intentionally not resprayed with Coopertox on August 2 There was no significant difference between Ectiban Pour-On to the backline or to the face nor between these treatments and the Coopertox body spray as determined from mean totals on Horn fly populations for the entire trial period June 10 to October 17 all three treatments reduced horn flies significantly better (P lt 0005) than the control (Table 3)

Also included in Table 1 are the results for horn fly control following Ectiban Tape applications on September 2 Excellent control resulted for 4 weeks on taped-heifers in Groups 1 2 and 3 No significant difference occurred between tape treatments to the ear or tail but all 3 treatment groups showed significant fly reduction (P lt 0005) when compared to the control group (Table 4) Fly populations in control Group 7 decreased rapidly with the onset of cold nights during the week of October 10

The results on Face fly control are shown in Table 2 Relatively good control of this species occurred with the Pour-On treatments for about 2 weeks (June 10 to 24) -with almost similar results for the Coopertox spray Fly control on these same groups retreated on August 3 provided a shorter

period of control about 9 to 1i days the natural dccro(1s(~ in Face fly popula tion s dur i ng Ju 1 and Augus t as ev idenct~d in Control Group 7 is commonplace and fly numbers are too low to warrant reliable comparison witn treated animals There was no significant difference between the Ectiban Pour-On to the face or to the backlinebut both treatments -were significantly different (P lt 0005) than the Coopertox spray and the control (Table 3)

Also included in Table 2 are the results for Face fly control following Ectiban tape applications on September 2 Excellent (Group 2) to good (Group 3) control resulted one day after application with tapes applied to ear tags but control did not persist at a satisfactory level as evidenced by the increase in fly counts on September 9 there was poor control via tapes attached to the tail (Group 1) The poor significance of these results are shown in Table 4 Poor results were obtained on face fly ~ontrol upon retreatment of Groups 41 and 50n September 30 and similar JesuIts were evident on Group 6 which was resprayed wi th Co_opertlt~

Of interest in this trial were the results on Horn fly control from the small amount of Ectiban Pour-On to the face of animals Heretofore it was believed that a similar dose of a pesticide to the withers was more effective but if Face fly populations are the main target then face and head applications could serve a dual purpose to include Horn fly control

Early IrrIgation - Liquid Supplement Trial

RIck Delmas

This study was initiated In 1980 to study the performance of

cattle using liquid supplement and the effect of early irrigation of

annual grasslands for early fall growth on the performance of cattle

during the fall and winter grazing period

Though the trial needs to be continued for the next couple of

years the following are indicated from one years data

1) Early irrigation furnishes valuable early fall feed especially

in poor rainfall years

2) Liquid supplement doesnt appear to be as beneficial as concentrates

for young cattle during the fall and winter The conception rate

on cattle with only liquid supplement was 8 to 19 lower than on

the other three treatments Economically the liquid supplement

was half the cost or less of the concentrate excluding labor

From this sfandpoint alone a rancher may be wIlling to accept

a slightly lower conception rate to obtain the decreased labor

and supplement cost Each individual rancher must measure cost

versus production

EFFECT OF OAK TREE REMOVAL ON FORAGE PRODUCTION

1981 was the sixteenth year that forage production has been measured in this study I have considered terminating the measurements because yield increases have not been significant in three of the last four years (see table) However data show that increases were significant in all of the sixteen years in which forage production on the check treatment (area covered by live trees) was below the median of the period (1385 Ibacre) Therefore in the interest of economy only the check treatments will be sampled in high rainfall years If another poor feed year occurs soon we will measure all treatments

6 Progress Report (Progress uring report perio toward reaching objectives of this research) The Ecologv and Population Dynamics of Aphodius fimetarius

The ecological study of the dung beetle Aphodius fimetarius was continued by again monitoring the ability of males and females to hibshyernate (aestivate) from late Spring to Fall From May 29 through June 9 we collected and marked 3020 beetles with fluorescent dust Half of these were released into a beetle-proof screened field cage in the Scott 14 pasture and the other half were released into a s~milar cage at the Howarth pasture o Both cages enclosed about 30 ft of natural turf and each was supplied with fresh dung (beetle food) until no beetles were present These two cages were monitored for the re-eppearance of beetles from September through December and cattle droppings from various pastures were sampled for the presence of naturally appearing wild beetles

During the past year the first beetles appeared in pasture droppings on November 4 when the dung peds had an average of 27 beetlespad On different weeks from November 11 through December 11 the density of ~ fimetarius remained fairly stable at 29 21 23 end 25 beetlespad As in previous years the beetle density then began to decline with 15pad on December 15 and less than one per pad on January 7 1982 In the Fall of 1981 beetles that had been marked and released into the experimental cages first appeared in the Scott 14 pasture on November 9 5 days after beetles first appeared in cattle dung pads in pastures The marked beetles contshyinued to appear in the Scott 14 cage through December with one beetle last appearing on December 16 No beetles were recovered in the Howarth pasture cage and through December 16 only 1 of marked beetles had been recovered in the Scott 14 cage This is in marked contrast to the cage recapture rates of 57 in the Scott pasture and 104 in the Howarth pasture It appears that beetles marked with the fluorescent dust suffershyed heavy mortality most of the marked beetles recovered had only a few particles of dust under the elytra or under the membraneous wings Nevertheless recapture of marked beetles confirmed that ~ fimetarius naturally hibernates (aestivates) in the ground for about 5 months in this part of California Other methods of marking beetles will be tested during the next seaSon

The objectives of this research were outlined in the 1980 report Many of the same trends observed in 1980 were repeated in 1981 Body weights of the cows were positively related to level of supplementation

(Table 1) The greatest effect was observed at the start of the breeding season where the difference between the unsupplemented and 25 times supplemented cows was nearly 100 kg

Weaning weight of the calves (Table 2) reflected the plane of nutrition of the cows Although weaning weights were enhanced by supplementation the largest differences in body weights occurred at the times the dams were mated Body weights of the calves reflected differential milk production of the cows

As in the previous year birth weight of the calves was not affected by plane of nutrition of the cows

6 Progress Report (Progress during report period toward reaching objectives of this research)

The major objectives of this research with Hereford cattle are (1) to determine if individual differences in mounting frequency by juvenile males correlate with individual differences in sexual motivation and performance as adults (2) to determine the degree of correlation between sexual behaviors and other biological traits (eg aggressive behavior semen characteristics hormone levels body size scrotal circumference) (3) to determine the function of mounting exshyperience on the development of sexual behavior and (4) to determine the role of penile stimulation on the development of sexual behavior

Over the last 4 years 78 bulls have been obtained from the SFRFS herd to investigate these questions Twenty-four male calves were brought to Davis from SFRFS in May 1981 to be used in studying objective 114 No observations were made on this group at the Field Station

Prior to 1981 all of our observations on juvenile mounting (Objectives 1 and 3) were made in confined situations where estrous heifers were provided as mountingstimuli and inter-animal contacts were frequent To determine the frequency of juvenile mounting in a more typical range environment 10 male and 9 female purebredHereford calves were observed between January 13 and March 22 1981 for a total of 40 hrs (29 different days) The calves ranged in age from 48 to 102 days (x = 80 days) at the start of observation A total of 394 calf observation hours were made on the 10 bull calves in the group and 749 calf hours on all 19 calves

Relative to our studies in confinement the rate of juvenile mounting in a typical range environment is very low A total of 15 mount intentions 12 mount attempts and 6 mounts (33 mount responses) were observed during the 40 hrs of observation Except for one mount intention all of the mounting activities were exhibited by bull calves The rate of mount responses was 0084 per bull calf per hour of observation Nearly all of the mounting behaviors were observed near the feed trough following feeding of supplements Supplemental feeding was terminated on February 25th and no sexual activity was observed among calves after that date

It was concluded that the mounting experience of 2-12 to 4-12 mo juvenilecalves in a ranqe environment is very limited

In the lower Plot near the Yuba River deer and cattle damage al1d some porcupine debarking have greatly reduced the choice of species here The above pines Arizona cypress plus possibly tamarisk aphylla and coast redwood still appear promising

The North Plot after 3 years of trial plantings versus 4 for the other plots shows promising results for only Arizona cypress Eucalyptus grandis from 2 sources and tamarisk aphylla It is too early to rate the remainj~g species over-all survival rates of which are generally low

No fertilizer tablets have been applied to any of these plots because other factors limiting growth and survival appear more Important There was no serious rodent or insect damage noted in any of the 3 plots this past year and irrigation practices have been generally good probably supplying around 3 acre feet per growing season of about 6 months

It is now planned to establish semi-commercial plots of a minimum of 112 acre for each of at least 5 of the most promising species in another area of the Sierra Field Station

Development work continued in the Campbell Field A fall-1980 seeding of a perennia grass-legume pasture mixture on the new irrigated pasture areas was successful except for parts of some fields where irrigation water (surface flow) failed to reach In general the newly-installed irrigation system performed well

The following work was done on or related to the range fertilization study being conducted on the Forbes Flll44 series fields

a Soil samples were taken from each of the 16 fields Analyses will be made for P 5 Ca Mg K and pH

b In cooperation with M B Jones (HFS) field plots were established at eight locations (4 north-facing aspects 4 south-facing) A factorial design was used to compare 4 levels of N (as urea) and 4 levels of P (as low-S concentrated superphosphate) plus an exploratory for several combinations of NPS with two replications at each locati r

c Also in cooperation with M B Jones a greenhouse pot test was set up at the Hopland Field station with rate-element combinations to match those in the field plots using soil collected at the field locations for the eight replications The pots were seeded with a mixture of sub and rose clovers together with soft chess

d M R George and W J Clawson located sites for a grazing utilization study employing 10 x 10 exclosures

6 Progress Report (Progress during report period toward reaching objectives of this research)

Four pairs of 14 acre plots were established during the fall of 1979 The Blue Oak overstory of these paired plots was approximately 0 25 50 and 75 The tree overstory was removed from one set of four plots by February 15 1980 and 12 wire mesh igloo type cages were placed on all plots by December 1980 Cages were located under tree canopy (or former tree canopy) and in the open using a stratified random procedure with proportional allocation

During 1981 three successive clippings were taken from inside the wire cages to determine the total standing crop present on February 21 (early season) April 3 amp 4 (mid-season) and June 2 (late season)

Preliminary Results (1981)

Uncleared plots 25 50 and 75 overstory cover Standing crop at any season did not differ appreciably by overstory level (Fig 1) When compared with uncleared open (0 overstory cover) plots standing crop was significantly less in uncleared plots at late season but not at early and mid-season Overstory cover and standing crop are not significantly correlated for any season (Fig 2)

Cleared Plots 25 50 and 75 prior overstory cover Standing crop is positively correlated with prior overstory cover particularly when uncleared open (0 overstory cover) plots are included in the comparison (Fig 2)

Tree removal greatly increased standing crop at all three seasons of harvest for all overstory cover levels (Fig 1) When compared to uncleared plots of the same overstory cover level these increases were 100 early season 133 midshyseason and 80 late season

6 Progress Report (Progress during report period toward reaching objectives of this research)

This experiment was undertaken to assess the efficacy and safety of a salt selenium mixture for supplementing range cows

Approximately a years data have been obtained on two groups each of 19 mature Hereford cows grazing range and offered two salt-selenium mineral mixtures free choice The concentration of selenium in one mixture was 40 ppm (low Se group) and the other 80 ppm (high Se group) These levels represent 2 and 4 times the maximal level currently permitted by FDA

Blood selenium concentrations (Figure 1) were determined on each animal at weekly intervals initially then at monthy intervals Intake of the salt-selenium mixture was also measured at monthly intervals to obtain total group mean intake of selenium

Blood selenium concentration rose from the initial concentration of 0035 ~gml to a maxima of approximately 0225 ~gm1 in the high group and 0150 ~gm1 in the low group at about 12 weeks Then maximal concentrations are within the range of normality and in no way indicate selenium toxicity

Intake of the salt-selenium mixture was not well correlated with blood concentration of se1eniUffl

Then data indicate that the FDA maximal level of 20 ppm selenium in salt supplements is conservative and may be ineffectual in areas of selenium deficiency There was no significant difference in the weight of the cows at the time the calves were weaned - low group 487 ~ 48 kg high group - 481 ~ 57 kg

SlJotMARY OF COMMENTS

The foothills of California offer an ideal place for people

to pursue farming Farming in the tradi tional sense family cerltered

labor interlsive small machinery oriented conservation minded small

Hopefully the U C Sierra Foothill Range Field Station will accept

and meet the challenge of providing research and information appropriate

to the fledgling development of a foothill agriculture ethic in which

the quality of food and living is paramount Projects of this nature

are few in the 1981 annual report Possibly we can make II greeter

contribution to foothill farming in the future

Evaluation of Ectiban Formulations For Fly Control on Cattle U C Sierra Foothill Range Field Station California 1981

E C Loomis PhD Parasitologist Lorry L Dunning Staff Research Associate

Extension Veterinary Medicine University of California Davis 95616

INTRODUCTION

Sixty (60)- Hereford heifers (avg wt4Q0 lbs) maintained on irrigated pasture at the U C Field Station were used for a fly control trial using Ectiban Pour~On and~Ectiban insecticide Ear Tag Tapes The heifers were divided into 6 equal groups of 10 each and were identified as groups 1 to 6 Twenty-five heifers of similar age and weight were kept on dry rangeland about 12 mile distant and served as Group 7 for a control (untreated) All 85 heifers were rated for horn fly densities in corrals prior to group separation and treatment but face fly counts were made in the field one week later

MATERIALS AND PROCEDURES

Ectiban formulations for trial evaluation consisted of a ready-to-use 1 Permethrin Pour-On (GFU003 Red 6766 dated 32481) and I-gram active ingredient Permethrin Ear Tag tapes for application to cattle ear tags These formulations were compared to a standard registered 005 spray using Coopertox Extra (Toxaphene 45 Lindane 196gt

Ectiban Pour-On was applied by means of 4 oz capacity metal dippers to 4 groups at a dosage of 12 ozcwt initially on June 10 and retreated on August 3 Groups 1 and 4 received a backline application while groups 2 and 5 received a face and poll application Groups 3 and 6 were sprayed over the entire body on June 10 and only Group 6 W4S resprayed on September 30 using 12 gallon (70 ozgt of Coopertox solution per head from a U C power sprayer equipped with a 6 HP Briggs amp Stratton engine plus by-pass pump system operated at 300 psi

Ectiban Ear Tag tapes for ear tag application arrived midway through the trial and some of the groups were split for tape application when retreatment was indicated on September 2 Groups 2 and 3 received one tape per heifer attached around the neck of the ear tag and Group I had a tape wrapped around the _end of the tail (above the switch) and secured with adhesive duct tape Groups 4 to 6 were not retreated at this time in order to determine possible effects of fly control from Ectiban-taped heifers which shared common fence lines and

2

exposure with the 3 Groups Following observations on September 23 it was decided to retreat Groups 4 to 6 on September 30 using the same Pour-On and Spray regimen as applied at the start of the trial

Visual fly counts by eye or with the aid of 7 x 50 binoculars were made in most cases by one observer on all 10 heifers in each of 6 Groups and on 10 of the 25 heifers in control Group 7 Counts were made from lOAM to 2PM at weekly intervals Horn fly counts (H irritans) were made on flies resting on one side of the body (withers ribcage and upper legs) and on Face flies (M autumnalis) resting on the face and head area

O~e way analysis of variance was used to determine if overall trea-tment means varied significantly Fishers LSD method was used to compare where differences occurred between treatment means

RESULTS AND DISCUSSION

The results on Horn fly control are shown in Table 1 Excellent control was obtained for 4 weeks (June 10 to July 7) for Ectiban backline Pour-On to Groups 1 and 4 while excellent to good control resulted from Ectiban face Pour-on on Groups 2 and 5 for the same 4 weeks Coopertox spray on Groups 3 and 6 provided excellent control for only 2 weeks (June 10 to 24) Surprisingly retreatment of the 4 Ectiban groups on August 2 provided not more than 2 weeks of satisfactory control Of equal interest was the dramatic decrease in horn flies for two weeks on Group 3 but only slightly so on Group 6 both of which were intentionally not resprayed with Coopertox on August 2 There was no significant difference between Ectiban Pour-On to the backline or to the face nor between these treatments and the Coopertox body spray as determined from mean totals on Horn fly populations for the entire trial period June 10 to October 17 all three treatments reduced horn flies significantly better (P lt 0005) than the control (Table 3)

Also included in Table 1 are the results for horn fly control following Ectiban Tape applications on September 2 Excellent control resulted for 4 weeks on taped-heifers in Groups 1 2 and 3 No significant difference occurred between tape treatments to the ear or tail but all 3 treatment groups showed significant fly reduction (P lt 0005) when compared to the control group (Table 4) Fly populations in control Group 7 decreased rapidly with the onset of cold nights during the week of October 10

The results on Face fly control are shown in Table 2 Relatively good control of this species occurred with the Pour-On treatments for about 2 weeks (June 10 to 24) -with almost similar results for the Coopertox spray Fly control on these same groups retreated on August 3 provided a shorter

period of control about 9 to 1i days the natural dccro(1s(~ in Face fly popula tion s dur i ng Ju 1 and Augus t as ev idenct~d in Control Group 7 is commonplace and fly numbers are too low to warrant reliable comparison witn treated animals There was no significant difference between the Ectiban Pour-On to the face or to the backlinebut both treatments -were significantly different (P lt 0005) than the Coopertox spray and the control (Table 3)

Also included in Table 2 are the results for Face fly control following Ectiban tape applications on September 2 Excellent (Group 2) to good (Group 3) control resulted one day after application with tapes applied to ear tags but control did not persist at a satisfactory level as evidenced by the increase in fly counts on September 9 there was poor control via tapes attached to the tail (Group 1) The poor significance of these results are shown in Table 4 Poor results were obtained on face fly ~ontrol upon retreatment of Groups 41 and 50n September 30 and similar JesuIts were evident on Group 6 which was resprayed wi th Co_opertlt~

Of interest in this trial were the results on Horn fly control from the small amount of Ectiban Pour-On to the face of animals Heretofore it was believed that a similar dose of a pesticide to the withers was more effective but if Face fly populations are the main target then face and head applications could serve a dual purpose to include Horn fly control

Early IrrIgation - Liquid Supplement Trial

RIck Delmas

This study was initiated In 1980 to study the performance of

cattle using liquid supplement and the effect of early irrigation of

annual grasslands for early fall growth on the performance of cattle

during the fall and winter grazing period

Though the trial needs to be continued for the next couple of

years the following are indicated from one years data

1) Early irrigation furnishes valuable early fall feed especially

in poor rainfall years

2) Liquid supplement doesnt appear to be as beneficial as concentrates

for young cattle during the fall and winter The conception rate

on cattle with only liquid supplement was 8 to 19 lower than on

the other three treatments Economically the liquid supplement

was half the cost or less of the concentrate excluding labor

From this sfandpoint alone a rancher may be wIlling to accept

a slightly lower conception rate to obtain the decreased labor

and supplement cost Each individual rancher must measure cost

versus production

EFFECT OF OAK TREE REMOVAL ON FORAGE PRODUCTION

1981 was the sixteenth year that forage production has been measured in this study I have considered terminating the measurements because yield increases have not been significant in three of the last four years (see table) However data show that increases were significant in all of the sixteen years in which forage production on the check treatment (area covered by live trees) was below the median of the period (1385 Ibacre) Therefore in the interest of economy only the check treatments will be sampled in high rainfall years If another poor feed year occurs soon we will measure all treatments

6 Progress Report (Progress uring report perio toward reaching objectives of this research) The Ecologv and Population Dynamics of Aphodius fimetarius

The ecological study of the dung beetle Aphodius fimetarius was continued by again monitoring the ability of males and females to hibshyernate (aestivate) from late Spring to Fall From May 29 through June 9 we collected and marked 3020 beetles with fluorescent dust Half of these were released into a beetle-proof screened field cage in the Scott 14 pasture and the other half were released into a s~milar cage at the Howarth pasture o Both cages enclosed about 30 ft of natural turf and each was supplied with fresh dung (beetle food) until no beetles were present These two cages were monitored for the re-eppearance of beetles from September through December and cattle droppings from various pastures were sampled for the presence of naturally appearing wild beetles

During the past year the first beetles appeared in pasture droppings on November 4 when the dung peds had an average of 27 beetlespad On different weeks from November 11 through December 11 the density of ~ fimetarius remained fairly stable at 29 21 23 end 25 beetlespad As in previous years the beetle density then began to decline with 15pad on December 15 and less than one per pad on January 7 1982 In the Fall of 1981 beetles that had been marked and released into the experimental cages first appeared in the Scott 14 pasture on November 9 5 days after beetles first appeared in cattle dung pads in pastures The marked beetles contshyinued to appear in the Scott 14 cage through December with one beetle last appearing on December 16 No beetles were recovered in the Howarth pasture cage and through December 16 only 1 of marked beetles had been recovered in the Scott 14 cage This is in marked contrast to the cage recapture rates of 57 in the Scott pasture and 104 in the Howarth pasture It appears that beetles marked with the fluorescent dust suffershyed heavy mortality most of the marked beetles recovered had only a few particles of dust under the elytra or under the membraneous wings Nevertheless recapture of marked beetles confirmed that ~ fimetarius naturally hibernates (aestivates) in the ground for about 5 months in this part of California Other methods of marking beetles will be tested during the next seaSon

6 Progress Report (Progress during report period toward reaching objectives of this research)

An evaluation was undertaken of the necessity for vitamin A supplementation of range cows

A group of 12 cows were grazed on range without access to irrigated pasture or B carotene supplements At monthly intervals over the past year liver biopsies were performed and blood collected for carotene and vitamin A determinations

At no time did circulating vitamin A concentrations indicate that supplementation was necessary

The relationship between hepatic reserves and circulating levels is being examined

The objectives of this research were outlined in the 1980 report Many of the same trends observed in 1980 were repeated in 1981 Body weights of the cows were positively related to level of supplementation

(Table 1) The greatest effect was observed at the start of the breeding season where the difference between the unsupplemented and 25 times supplemented cows was nearly 100 kg

Weaning weight of the calves (Table 2) reflected the plane of nutrition of the cows Although weaning weights were enhanced by supplementation the largest differences in body weights occurred at the times the dams were mated Body weights of the calves reflected differential milk production of the cows

As in the previous year birth weight of the calves was not affected by plane of nutrition of the cows

6 Progress Report (Progress during report period toward reaching objectives of this research)

The major objectives of this research with Hereford cattle are (1) to determine if individual differences in mounting frequency by juvenile males correlate with individual differences in sexual motivation and performance as adults (2) to determine the degree of correlation between sexual behaviors and other biological traits (eg aggressive behavior semen characteristics hormone levels body size scrotal circumference) (3) to determine the function of mounting exshyperience on the development of sexual behavior and (4) to determine the role of penile stimulation on the development of sexual behavior

Over the last 4 years 78 bulls have been obtained from the SFRFS herd to investigate these questions Twenty-four male calves were brought to Davis from SFRFS in May 1981 to be used in studying objective 114 No observations were made on this group at the Field Station

Prior to 1981 all of our observations on juvenile mounting (Objectives 1 and 3) were made in confined situations where estrous heifers were provided as mountingstimuli and inter-animal contacts were frequent To determine the frequency of juvenile mounting in a more typical range environment 10 male and 9 female purebredHereford calves were observed between January 13 and March 22 1981 for a total of 40 hrs (29 different days) The calves ranged in age from 48 to 102 days (x = 80 days) at the start of observation A total of 394 calf observation hours were made on the 10 bull calves in the group and 749 calf hours on all 19 calves

Relative to our studies in confinement the rate of juvenile mounting in a typical range environment is very low A total of 15 mount intentions 12 mount attempts and 6 mounts (33 mount responses) were observed during the 40 hrs of observation Except for one mount intention all of the mounting activities were exhibited by bull calves The rate of mount responses was 0084 per bull calf per hour of observation Nearly all of the mounting behaviors were observed near the feed trough following feeding of supplements Supplemental feeding was terminated on February 25th and no sexual activity was observed among calves after that date

It was concluded that the mounting experience of 2-12 to 4-12 mo juvenilecalves in a ranqe environment is very limited

promising at present arc Monterey pine coast redwood and varieties of Pinus halepensis (brutia and eldarica) The most promising hardwoods to date are Eucalyptus globulus camaldulensis (2 variants) urnigera and grandis

In the lower Plot near the Yuba River deer and cattle damage al1d some porcupine debarking have greatly reduced the choice of species here The above pines Arizona cypress plus possibly tamarisk aphylla and coast redwood still appear promising

The North Plot after 3 years of trial plantings versus 4 for the other plots shows promising results for only Arizona cypress Eucalyptus grandis from 2 sources and tamarisk aphylla It is too early to rate the remainj~g species over-all survival rates of which are generally low

No fertilizer tablets have been applied to any of these plots because other factors limiting growth and survival appear more Important There was no serious rodent or insect damage noted in any of the 3 plots this past year and irrigation practices have been generally good probably supplying around 3 acre feet per growing season of about 6 months

It is now planned to establish semi-commercial plots of a minimum of 112 acre for each of at least 5 of the most promising species in another area of the Sierra Field Station

Development work continued in the Campbell Field A fall-1980 seeding of a perennia grass-legume pasture mixture on the new irrigated pasture areas was successful except for parts of some fields where irrigation water (surface flow) failed to reach In general the newly-installed irrigation system performed well

The following work was done on or related to the range fertilization study being conducted on the Forbes Flll44 series fields

a Soil samples were taken from each of the 16 fields Analyses will be made for P 5 Ca Mg K and pH

b In cooperation with M B Jones (HFS) field plots were established at eight locations (4 north-facing aspects 4 south-facing) A factorial design was used to compare 4 levels of N (as urea) and 4 levels of P (as low-S concentrated superphosphate) plus an exploratory for several combinations of NPS with two replications at each locati r

c Also in cooperation with M B Jones a greenhouse pot test was set up at the Hopland Field station with rate-element combinations to match those in the field plots using soil collected at the field locations for the eight replications The pots were seeded with a mixture of sub and rose clovers together with soft chess

d M R George and W J Clawson located sites for a grazing utilization study employing 10 x 10 exclosures

e A field-scale experiment with aerial application of nitrogen (as urea) at 0 40 80 and 120 kgha rates (two fields per replication two replications per treatment) is planned for fall 1982 following evaluation of the tests described above and results of a pre-experiment calibration grazing (with steers) beginning February 1982 Roy Hull J G Morris and R E Delmas are cooperators from the Department of Animal Science

f Using Sobrante-Las Posas soil collected at the SFRFS a study of effects of levels of single superphosphate with and without N and effects of fertiizer placement on emergence growth and nodulation of sub clover was completed at Davis- bull

6 Progress Report (Progress during report period toward reaching objectives of this research)

Four pairs of 14 acre plots were established during the fall of 1979 The Blue Oak overstory of these paired plots was approximately 0 25 50 and 75 The tree overstory was removed from one set of four plots by February 15 1980 and 12 wire mesh igloo type cages were placed on all plots by December 1980 Cages were located under tree canopy (or former tree canopy) and in the open using a stratified random procedure with proportional allocation

During 1981 three successive clippings were taken from inside the wire cages to determine the total standing crop present on February 21 (early season) April 3 amp 4 (mid-season) and June 2 (late season)

Preliminary Results (1981)

Uncleared plots 25 50 and 75 overstory cover Standing crop at any season did not differ appreciably by overstory level (Fig 1) When compared with uncleared open (0 overstory cover) plots standing crop was significantly less in uncleared plots at late season but not at early and mid-season Overstory cover and standing crop are not significantly correlated for any season (Fig 2)

Cleared Plots 25 50 and 75 prior overstory cover Standing crop is positively correlated with prior overstory cover particularly when uncleared open (0 overstory cover) plots are included in the comparison (Fig 2)

Tree removal greatly increased standing crop at all three seasons of harvest for all overstory cover levels (Fig 1) When compared to uncleared plots of the same overstory cover level these increases were 100 early season 133 midshyseason and 80 late season

6 Progress Report (Progress during report period toward reaching objectives of this research)

This experiment was undertaken to assess the efficacy and safety of a salt selenium mixture for supplementing range cows

Approximately a years data have been obtained on two groups each of 19 mature Hereford cows grazing range and offered two salt-selenium mineral mixtures free choice The concentration of selenium in one mixture was 40 ppm (low Se group) and the other 80 ppm (high Se group) These levels represent 2 and 4 times the maximal level currently permitted by FDA

Blood selenium concentrations (Figure 1) were determined on each animal at weekly intervals initially then at monthy intervals Intake of the salt-selenium mixture was also measured at monthly intervals to obtain total group mean intake of selenium

Blood selenium concentration rose from the initial concentration of 0035 ~gml to a maxima of approximately 0225 ~gm1 in the high group and 0150 ~gm1 in the low group at about 12 weeks Then maximal concentrations are within the range of normality and in no way indicate selenium toxicity

Intake of the salt-selenium mixture was not well correlated with blood concentration of se1eniUffl

Then data indicate that the FDA maximal level of 20 ppm selenium in salt supplements is conservative and may be ineffectual in areas of selenium deficiency There was no significant difference in the weight of the cows at the time the calves were weaned - low group 487 ~ 48 kg high group - 481 ~ 57 kg

The foothills of California offer an ideal place for people

to pursue farming Farming in the tradi tional sense family cerltered

labor interlsive small machinery oriented conservation minded small

Hopefully the U C Sierra Foothill Range Field Station will accept

and meet the challenge of providing research and information appropriate

to the fledgling development of a foothill agriculture ethic in which

the quality of food and living is paramount Projects of this nature

are few in the 1981 annual report Possibly we can make II greeter

contribution to foothill farming in the future

The breeding program utilizing polled Hereford sires AI continues A polled Hereford bull from a production tested herd was obtained an performance data from the purebred cow ~erdmiddotcontinues Test data of weaner bull calves with the best calves selected for use in the Sierra herds also continues

Weaning weight of calves from the cow herds was lower by 40-50 1bs due to a very rough 1980-81 winter Range clearing continues along with increased use of the heifers reared at Sierra as replacements in the cow herds Studies utilizing the progeny of the Sierra cow herds continue at Davis These progeny were transshyferred to trials for the Animal Science Faculty as well as utilized for teachshying In addition other units of the University have use of progeny of the Sierra herds such as Veterinary Medicine Cooperative Extension Entomology etc

An experiment is being conducted to determine the feasibility of producing twin calves under range conditions This research is a continuation of similar research carried out on the UCD campus and is designed to study the production of twins under practical range conditions Beef females of low and high milk producing abilityHerefords and Hereford x Holstein crossbreds respectively were induced to producetwins by embryo transfer Dams are being maintained throughout pregnancy and lactation on irrigated pasture Birth and weaning weights of single and twin calves as well as complications such as calf mortality retained placentas dystocia are being recorded

Evaluation of Ectiban Formulations For Fly Control on Cattle U C Sierra Foothill Range Field Station California 1981

E C Loomis PhD Parasitologist Lorry L Dunning Staff Research Associate

Extension Veterinary Medicine University of California Davis 95616

INTRODUCTION

Sixty (60)- Hereford heifers (avg wt4Q0 lbs) maintained on irrigated pasture at the U C Field Station were used for a fly control trial using Ectiban Pour~On and~Ectiban insecticide Ear Tag Tapes The heifers were divided into 6 equal groups of 10 each and were identified as groups 1 to 6 Twenty-five heifers of similar age and weight were kept on dry rangeland about 12 mile distant and served as Group 7 for a control (untreated) All 85 heifers were rated for horn fly densities in corrals prior to group separation and treatment but face fly counts were made in the field one week later

MATERIALS AND PROCEDURES

Ectiban formulations for trial evaluation consisted of a ready-to-use 1 Permethrin Pour-On (GFU003 Red 6766 dated 32481) and I-gram active ingredient Permethrin Ear Tag tapes for application to cattle ear tags These formulations were compared to a standard registered 005 spray using Coopertox Extra (Toxaphene 45 Lindane 196gt

Ectiban Pour-On was applied by means of 4 oz capacity metal dippers to 4 groups at a dosage of 12 ozcwt initially on June 10 and retreated on August 3 Groups 1 and 4 received a backline application while groups 2 and 5 received a face and poll application Groups 3 and 6 were sprayed over the entire body on June 10 and only Group 6 W4S resprayed on September 30 using 12 gallon (70 ozgt of Coopertox solution per head from a U C power sprayer equipped with a 6 HP Briggs amp Stratton engine plus by-pass pump system operated at 300 psi

Ectiban Ear Tag tapes for ear tag application arrived midway through the trial and some of the groups were split for tape application when retreatment was indicated on September 2 Groups 2 and 3 received one tape per heifer attached around the neck of the ear tag and Group I had a tape wrapped around the _end of the tail (above the switch) and secured with adhesive duct tape Groups 4 to 6 were not retreated at this time in order to determine possible effects of fly control from Ectiban-taped heifers which shared common fence lines and

2

exposure with the 3 Groups Following observations on September 23 it was decided to retreat Groups 4 to 6 on September 30 using the same Pour-On and Spray regimen as applied at the start of the trial

Visual fly counts by eye or with the aid of 7 x 50 binoculars were made in most cases by one observer on all 10 heifers in each of 6 Groups and on 10 of the 25 heifers in control Group 7 Counts were made from lOAM to 2PM at weekly intervals Horn fly counts (H irritans) were made on flies resting on one side of the body (withers ribcage and upper legs) and on Face flies (M autumnalis) resting on the face and head area

O~e way analysis of variance was used to determine if overall trea-tment means varied significantly Fishers LSD method was used to compare where differences occurred between treatment means

RESULTS AND DISCUSSION

The results on Horn fly control are shown in Table 1 Excellent control was obtained for 4 weeks (June 10 to July 7) for Ectiban backline Pour-On to Groups 1 and 4 while excellent to good control resulted from Ectiban face Pour-on on Groups 2 and 5 for the same 4 weeks Coopertox spray on Groups 3 and 6 provided excellent control for only 2 weeks (June 10 to 24) Surprisingly retreatment of the 4 Ectiban groups on August 2 provided not more than 2 weeks of satisfactory control Of equal interest was the dramatic decrease in horn flies for two weeks on Group 3 but only slightly so on Group 6 both of which were intentionally not resprayed with Coopertox on August 2 There was no significant difference between Ectiban Pour-On to the backline or to the face nor between these treatments and the Coopertox body spray as determined from mean totals on Horn fly populations for the entire trial period June 10 to October 17 all three treatments reduced horn flies significantly better (P lt 0005) than the control (Table 3)

Also included in Table 1 are the results for horn fly control following Ectiban Tape applications on September 2 Excellent control resulted for 4 weeks on taped-heifers in Groups 1 2 and 3 No significant difference occurred between tape treatments to the ear or tail but all 3 treatment groups showed significant fly reduction (P lt 0005) when compared to the control group (Table 4) Fly populations in control Group 7 decreased rapidly with the onset of cold nights during the week of October 10

The results on Face fly control are shown in Table 2 Relatively good control of this species occurred with the Pour-On treatments for about 2 weeks (June 10 to 24) -with almost similar results for the Coopertox spray Fly control on these same groups retreated on August 3 provided a shorter

period of control about 9 to 1i days the natural dccro(1s(~ in Face fly popula tion s dur i ng Ju 1 and Augus t as ev idenct~d in Control Group 7 is commonplace and fly numbers are too low to warrant reliable comparison witn treated animals There was no significant difference between the Ectiban Pour-On to the face or to the backlinebut both treatments -were significantly different (P lt 0005) than the Coopertox spray and the control (Table 3)

Also included in Table 2 are the results for Face fly control following Ectiban tape applications on September 2 Excellent (Group 2) to good (Group 3) control resulted one day after application with tapes applied to ear tags but control did not persist at a satisfactory level as evidenced by the increase in fly counts on September 9 there was poor control via tapes attached to the tail (Group 1) The poor significance of these results are shown in Table 4 Poor results were obtained on face fly ~ontrol upon retreatment of Groups 41 and 50n September 30 and similar JesuIts were evident on Group 6 which was resprayed wi th Co_opertlt~

Of interest in this trial were the results on Horn fly control from the small amount of Ectiban Pour-On to the face of animals Heretofore it was believed that a similar dose of a pesticide to the withers was more effective but if Face fly populations are the main target then face and head applications could serve a dual purpose to include Horn fly control

Early IrrIgation - Liquid Supplement Trial

RIck Delmas

This study was initiated In 1980 to study the performance of

cattle using liquid supplement and the effect of early irrigation of

annual grasslands for early fall growth on the performance of cattle

during the fall and winter grazing period

Though the trial needs to be continued for the next couple of

years the following are indicated from one years data

1) Early irrigation furnishes valuable early fall feed especially

in poor rainfall years

2) Liquid supplement doesnt appear to be as beneficial as concentrates

for young cattle during the fall and winter The conception rate

on cattle with only liquid supplement was 8 to 19 lower than on

the other three treatments Economically the liquid supplement

was half the cost or less of the concentrate excluding labor

From this sfandpoint alone a rancher may be wIlling to accept

a slightly lower conception rate to obtain the decreased labor

and supplement cost Each individual rancher must measure cost

versus production

EFFECT OF OAK TREE REMOVAL ON FORAGE PRODUCTION

1981 was the sixteenth year that forage production has been measured in this study I have considered terminating the measurements because yield increases have not been significant in three of the last four years (see table) However data show that increases were significant in all of the sixteen years in which forage production on the check treatment (area covered by live trees) was below the median of the period (1385 Ibacre) Therefore in the interest of economy only the check treatments will be sampled in high rainfall years If another poor feed year occurs soon we will measure all treatments

6 Progress Report (Progress uring report perio toward reaching objectives of this research) The Ecologv and Population Dynamics of Aphodius fimetarius

The ecological study of the dung beetle Aphodius fimetarius was continued by again monitoring the ability of males and females to hibshyernate (aestivate) from late Spring to Fall From May 29 through June 9 we collected and marked 3020 beetles with fluorescent dust Half of these were released into a beetle-proof screened field cage in the Scott 14 pasture and the other half were released into a s~milar cage at the Howarth pasture o Both cages enclosed about 30 ft of natural turf and each was supplied with fresh dung (beetle food) until no beetles were present These two cages were monitored for the re-eppearance of beetles from September through December and cattle droppings from various pastures were sampled for the presence of naturally appearing wild beetles

During the past year the first beetles appeared in pasture droppings on November 4 when the dung peds had an average of 27 beetlespad On different weeks from November 11 through December 11 the density of ~ fimetarius remained fairly stable at 29 21 23 end 25 beetlespad As in previous years the beetle density then began to decline with 15pad on December 15 and less than one per pad on January 7 1982 In the Fall of 1981 beetles that had been marked and released into the experimental cages first appeared in the Scott 14 pasture on November 9 5 days after beetles first appeared in cattle dung pads in pastures The marked beetles contshyinued to appear in the Scott 14 cage through December with one beetle last appearing on December 16 No beetles were recovered in the Howarth pasture cage and through December 16 only 1 of marked beetles had been recovered in the Scott 14 cage This is in marked contrast to the cage recapture rates of 57 in the Scott pasture and 104 in the Howarth pasture It appears that beetles marked with the fluorescent dust suffershyed heavy mortality most of the marked beetles recovered had only a few particles of dust under the elytra or under the membraneous wings Nevertheless recapture of marked beetles confirmed that ~ fimetarius naturally hibernates (aestivates) in the ground for about 5 months in this part of California Other methods of marking beetles will be tested during the next seaSon

6 Progress Report (Progress during report period toward reaching objectives of thi 5 research)

The objectives of this research were outlined in the 1980 report Many of the same trends observed in 1980 were repeated in 1981 Body weights of the cows were positively related to level of supplementation

(Table 1) The greatest effect was observed at the start of the breeding season where the difference between the unsupplemented and 25 times supplemented cows was nearly 100 kg

Shrunk all others full body weight

Weaning weight of the calves (Table 2) reflected the plane of nutrition of the cows Although weaning weights were enhanced by supplementation the largest differences in body weights occurred at the times the dams were mated Body weights of the calves reflected differential milk production of the cows

6 Progress Report (Progress during report period toward reaching objectives of this research)

The major objectives of this research with Hereford cattle are (1) to determine if individual differences in mounting frequency by juvenile males correlate with individual differences in sexual motivation and performance as adults (2) to determine the degree of correlation between sexual behaviors and other biological traits (eg aggressive behavior semen characteristics hormone levels body size scrotal circumference) (3) to determine the function of mounting exshyperience on the development of sexual behavior and (4) to determine the role of penile stimulation on the development of sexual behavior

Over the last 4 years 78 bulls have been obtained from the SFRFS herd to investigate these questions Twenty-four male calves were brought to Davis from SFRFS in May 1981 to be used in studying objective 114 No observations were made on this group at the Field Station

Prior to 1981 all of our observations on juvenile mounting (Objectives 1 and 3) were made in confined situations where estrous heifers were provided as mountingstimuli and inter-animal contacts were frequent To determine the frequency of juvenile mounting in a more typical range environment 10 male and 9 female purebredHereford calves were observed between January 13 and March 22 1981 for a total of 40 hrs (29 different days) The calves ranged in age from 48 to 102 days (x = 80 days) at the start of observation A total of 394 calf observation hours were made on the 10 bull calves in the group and 749 calf hours on all 19 calves

Relative to our studies in confinement the rate of juvenile mounting in a typical range environment is very low A total of 15 mount intentions 12 mount attempts and 6 mounts (33 mount responses) were observed during the 40 hrs of observation Except for one mount intention all of the mounting activities were exhibited by bull calves The rate of mount responses was 0084 per bull calf per hour of observation Nearly all of the mounting behaviors were observed near the feed trough following feeding of supplements Supplemental feeding was terminated on February 25th and no sexual activity was observed among calves after that date

It was concluded that the mounting experience of 2-12 to 4-12 mo juvenilecalves in a ranqe environment is very limited

CO1tinued work in the Tea Garden Plot fairly well protected from deer has show~ reasonably good resul ts for only a few coni fer~ ad hardwoods The 100St

promising at present arc Monterey pine coast redwood and varieties of Pinus halepensis (brutia and eldarica) The most promising hardwoods to date are Eucalyptus globulus camaldulensis (2 variants) urnigera and grandis

In the lower Plot near the Yuba River deer and cattle damage al1d some porcupine debarking have greatly reduced the choice of species here The above pines Arizona cypress plus possibly tamarisk aphylla and coast redwood still appear promising

The North Plot after 3 years of trial plantings versus 4 for the other plots shows promising results for only Arizona cypress Eucalyptus grandis from 2 sources and tamarisk aphylla It is too early to rate the remainj~g species over-all survival rates of which are generally low

No fertilizer tablets have been applied to any of these plots because other factors limiting growth and survival appear more Important There was no serious rodent or insect damage noted in any of the 3 plots this past year and irrigation practices have been generally good probably supplying around 3 acre feet per growing season of about 6 months

It is now planned to establish semi-commercial plots of a minimum of 112 acre for each of at least 5 of the most promising species in another area of the Sierra Field Station

Development work continued in the Campbell Field A fall-1980 seeding of a perennia grass-legume pasture mixture on the new irrigated pasture areas was successful except for parts of some fields where irrigation water (surface flow) failed to reach In general the newly-installed irrigation system performed well

The following work was done on or related to the range fertilization study being conducted on the Forbes Flll44 series fields

a Soil samples were taken from each of the 16 fields Analyses will be made for P 5 Ca Mg K and pH

b In cooperation with M B Jones (HFS) field plots were established at eight locations (4 north-facing aspects 4 south-facing) A factorial design was used to compare 4 levels of N (as urea) and 4 levels of P (as low-S concentrated superphosphate) plus an exploratory for several combinations of NPS with two replications at each locati r

c Also in cooperation with M B Jones a greenhouse pot test was set up at the Hopland Field station with rate-element combinations to match those in the field plots using soil collected at the field locations for the eight replications The pots were seeded with a mixture of sub and rose clovers together with soft chess

d M R George and W J Clawson located sites for a grazing utilization study employing 10 x 10 exclosures

e A field-scale experiment with aerial application of nitrogen (as urea) at 0 40 80 and 120 kgha rates (two fields per replication two replications per treatment) is planned for fall 1982 following evaluation of the tests described above and results of a pre-experiment calibration grazing (with steers) beginning February 1982 Roy Hull J G Morris and R E Delmas are cooperators from the Department of Animal Science

6 Progress Report (Progress during report period toward reaching objectives of this research)

Four pairs of 14 acre plots were established during the fall of 1979 The Blue Oak overstory of these paired plots was approximately 0 25 50 and 75 The tree overstory was removed from one set of four plots by February 15 1980 and 12 wire mesh igloo type cages were placed on all plots by December 1980 Cages were located under tree canopy (or former tree canopy) and in the open using a stratified random procedure with proportional allocation

During 1981 three successive clippings were taken from inside the wire cages to determine the total standing crop present on February 21 (early season) April 3 amp 4 (mid-season) and June 2 (late season)

Preliminary Results (1981)

Uncleared plots 25 50 and 75 overstory cover Standing crop at any season did not differ appreciably by overstory level (Fig 1) When compared with uncleared open (0 overstory cover) plots standing crop was significantly less in uncleared plots at late season but not at early and mid-season Overstory cover and standing crop are not significantly correlated for any season (Fig 2)

Cleared Plots 25 50 and 75 prior overstory cover Standing crop is positively correlated with prior overstory cover particularly when uncleared open (0 overstory cover) plots are included in the comparison (Fig 2)

Tree removal greatly increased standing crop at all three seasons of harvest for all overstory cover levels (Fig 1) When compared to uncleared plots of the same overstory cover level these increases were 100 early season 133 midshyseason and 80 late season

6 Progress Report (Progress during report period toward reaching objectives of this research)

This experiment was undertaken to assess the efficacy and safety of a salt selenium mixture for supplementing range cows

Approximately a years data have been obtained on two groups each of 19 mature Hereford cows grazing range and offered two salt-selenium mineral mixtures free choice The concentration of selenium in one mixture was 40 ppm (low Se group) and the other 80 ppm (high Se group) These levels represent 2 and 4 times the maximal level currently permitted by FDA

Blood selenium concentrations (Figure 1) were determined on each animal at weekly intervals initially then at monthy intervals Intake of the salt-selenium mixture was also measured at monthly intervals to obtain total group mean intake of selenium

Blood selenium concentration rose from the initial concentration of 0035 ~gml to a maxima of approximately 0225 ~gm1 in the high group and 0150 ~gm1 in the low group at about 12 weeks Then maximal concentrations are within the range of normality and in no way indicate selenium toxicity

Intake of the salt-selenium mixture was not well correlated with blood concentration of se1eniUffl

Then data indicate that the FDA maximal level of 20 ppm selenium in salt supplements is conservative and may be ineffectual in areas of selenium deficiency There was no significant difference in the weight of the cows at the time the calves were weaned - low group 487 ~ 48 kg high group - 481 ~ 57 kg

SlJotMARY OF COMMENTS

The foothills of California offer an ideal place for people

to pursue farming Farming in the tradi tional sense family cerltered

labor interlsive small machinery oriented conservation minded small

Hopefully the U C Sierra Foothill Range Field Station will accept

and meet the challenge of providing research and information appropriate

to the fledgling development of a foothill agriculture ethic in which

the quality of food and living is paramount Projects of this nature

are few in the 1981 annual report Possibly we can make II greeter

contribution to foothill farming in the future

The breeding program utilizing polled Hereford sires AI continues A polled Hereford bull from a production tested herd was obtained an performance data from the purebred cow ~erdmiddotcontinues Test data of weaner bull calves with the best calves selected for use in the Sierra herds also continues

Weaning weight of calves from the cow herds was lower by 40-50 1bs due to a very rough 1980-81 winter Range clearing continues along with increased use of the heifers reared at Sierra as replacements in the cow herds Studies utilizing the progeny of the Sierra cow herds continue at Davis These progeny were transshyferred to trials for the Animal Science Faculty as well as utilized for teachshying In addition other units of the University have use of progeny of the Sierra herds such as Veterinary Medicine Cooperative Extension Entomology etc

An experiment is being conducted to determine the feasibility of producing twin calves under range conditions This research is a continuation of similar research carried out on the UCD campus and is designed to study the production of twins under practical range conditions Beef females of low and high milk producing abilityHerefords and Hereford x Holstein crossbreds respectively were induced to producetwins by embryo transfer Dams are being maintained throughout pregnancy and lactation on irrigated pasture Birth and weaning weights of single and twin calves as well as complications such as calf mortality retained placentas dystocia are being recorded

Evaluation of Ectiban Formulations For Fly Control on Cattle U C Sierra Foothill Range Field Station California 1981

E C Loomis PhD Parasitologist Lorry L Dunning Staff Research Associate

Extension Veterinary Medicine University of California Davis 95616

INTRODUCTION

Sixty (60)- Hereford heifers (avg wt4Q0 lbs) maintained on irrigated pasture at the U C Field Station were used for a fly control trial using Ectiban Pour~On and~Ectiban insecticide Ear Tag Tapes The heifers were divided into 6 equal groups of 10 each and were identified as groups 1 to 6 Twenty-five heifers of similar age and weight were kept on dry rangeland about 12 mile distant and served as Group 7 for a control (untreated) All 85 heifers were rated for horn fly densities in corrals prior to group separation and treatment but face fly counts were made in the field one week later

MATERIALS AND PROCEDURES

Ectiban formulations for trial evaluation consisted of a ready-to-use 1 Permethrin Pour-On (GFU003 Red 6766 dated 32481) and I-gram active ingredient Permethrin Ear Tag tapes for application to cattle ear tags These formulations were compared to a standard registered 005 spray using Coopertox Extra (Toxaphene 45 Lindane 196gt

Ectiban Pour-On was applied by means of 4 oz capacity metal dippers to 4 groups at a dosage of 12 ozcwt initially on June 10 and retreated on August 3 Groups 1 and 4 received a backline application while groups 2 and 5 received a face and poll application Groups 3 and 6 were sprayed over the entire body on June 10 and only Group 6 W4S resprayed on September 30 using 12 gallon (70 ozgt of Coopertox solution per head from a U C power sprayer equipped with a 6 HP Briggs amp Stratton engine plus by-pass pump system operated at 300 psi

Ectiban Ear Tag tapes for ear tag application arrived midway through the trial and some of the groups were split for tape application when retreatment was indicated on September 2 Groups 2 and 3 received one tape per heifer attached around the neck of the ear tag and Group I had a tape wrapped around the _end of the tail (above the switch) and secured with adhesive duct tape Groups 4 to 6 were not retreated at this time in order to determine possible effects of fly control from Ectiban-taped heifers which shared common fence lines and

2

exposure with the 3 Groups Following observations on September 23 it was decided to retreat Groups 4 to 6 on September 30 using the same Pour-On and Spray regimen as applied at the start of the trial

Visual fly counts by eye or with the aid of 7 x 50 binoculars were made in most cases by one observer on all 10 heifers in each of 6 Groups and on 10 of the 25 heifers in control Group 7 Counts were made from lOAM to 2PM at weekly intervals Horn fly counts (H irritans) were made on flies resting on one side of the body (withers ribcage and upper legs) and on Face flies (M autumnalis) resting on the face and head area

O~e way analysis of variance was used to determine if overall trea-tment means varied significantly Fishers LSD method was used to compare where differences occurred between treatment means

RESULTS AND DISCUSSION

The results on Horn fly control are shown in Table 1 Excellent control was obtained for 4 weeks (June 10 to July 7) for Ectiban backline Pour-On to Groups 1 and 4 while excellent to good control resulted from Ectiban face Pour-on on Groups 2 and 5 for the same 4 weeks Coopertox spray on Groups 3 and 6 provided excellent control for only 2 weeks (June 10 to 24) Surprisingly retreatment of the 4 Ectiban groups on August 2 provided not more than 2 weeks of satisfactory control Of equal interest was the dramatic decrease in horn flies for two weeks on Group 3 but only slightly so on Group 6 both of which were intentionally not resprayed with Coopertox on August 2 There was no significant difference between Ectiban Pour-On to the backline or to the face nor between these treatments and the Coopertox body spray as determined from mean totals on Horn fly populations for the entire trial period June 10 to October 17 all three treatments reduced horn flies significantly better (P lt 0005) than the control (Table 3)

Also included in Table 1 are the results for horn fly control following Ectiban Tape applications on September 2 Excellent control resulted for 4 weeks on taped-heifers in Groups 1 2 and 3 No significant difference occurred between tape treatments to the ear or tail but all 3 treatment groups showed significant fly reduction (P lt 0005) when compared to the control group (Table 4) Fly populations in control Group 7 decreased rapidly with the onset of cold nights during the week of October 10

The results on Face fly control are shown in Table 2 Relatively good control of this species occurred with the Pour-On treatments for about 2 weeks (June 10 to 24) -with almost similar results for the Coopertox spray Fly control on these same groups retreated on August 3 provided a shorter

period of control about 9 to 1i days the natural dccro(1s(~ in Face fly popula tion s dur i ng Ju 1 and Augus t as ev idenct~d in Control Group 7 is commonplace and fly numbers are too low to warrant reliable comparison witn treated animals There was no significant difference between the Ectiban Pour-On to the face or to the backlinebut both treatments -were significantly different (P lt 0005) than the Coopertox spray and the control (Table 3)

Also included in Table 2 are the results for Face fly control following Ectiban tape applications on September 2 Excellent (Group 2) to good (Group 3) control resulted one day after application with tapes applied to ear tags but control did not persist at a satisfactory level as evidenced by the increase in fly counts on September 9 there was poor control via tapes attached to the tail (Group 1) The poor significance of these results are shown in Table 4 Poor results were obtained on face fly ~ontrol upon retreatment of Groups 41 and 50n September 30 and similar JesuIts were evident on Group 6 which was resprayed wi th Co_opertlt~

Of interest in this trial were the results on Horn fly control from the small amount of Ectiban Pour-On to the face of animals Heretofore it was believed that a similar dose of a pesticide to the withers was more effective but if Face fly populations are the main target then face and head applications could serve a dual purpose to include Horn fly control

Early IrrIgation - Liquid Supplement Trial

RIck Delmas

This study was initiated In 1980 to study the performance of

cattle using liquid supplement and the effect of early irrigation of

annual grasslands for early fall growth on the performance of cattle

during the fall and winter grazing period

Though the trial needs to be continued for the next couple of

years the following are indicated from one years data

1) Early irrigation furnishes valuable early fall feed especially

in poor rainfall years

2) Liquid supplement doesnt appear to be as beneficial as concentrates

for young cattle during the fall and winter The conception rate

on cattle with only liquid supplement was 8 to 19 lower than on

the other three treatments Economically the liquid supplement

was half the cost or less of the concentrate excluding labor

From this sfandpoint alone a rancher may be wIlling to accept

a slightly lower conception rate to obtain the decreased labor

and supplement cost Each individual rancher must measure cost

versus production

EFFECT OF OAK TREE REMOVAL ON FORAGE PRODUCTION

1981 was the sixteenth year that forage production has been measured in this study I have considered terminating the measurements because yield increases have not been significant in three of the last four years (see table) However data show that increases were significant in all of the sixteen years in which forage production on the check treatment (area covered by live trees) was below the median of the period (1385 Ibacre) Therefore in the interest of economy only the check treatments will be sampled in high rainfall years If another poor feed year occurs soon we will measure all treatments

6 Progress Report (Progress uring report perio toward reaching objectives of this research) The Ecologv and Population Dynamics of Aphodius fimetarius

The ecological study of the dung beetle Aphodius fimetarius was continued by again monitoring the ability of males and females to hibshyernate (aestivate) from late Spring to Fall From May 29 through June 9 we collected and marked 3020 beetles with fluorescent dust Half of these were released into a beetle-proof screened field cage in the Scott 14 pasture and the other half were released into a s~milar cage at the Howarth pasture o Both cages enclosed about 30 ft of natural turf and each was supplied with fresh dung (beetle food) until no beetles were present These two cages were monitored for the re-eppearance of beetles from September through December and cattle droppings from various pastures were sampled for the presence of naturally appearing wild beetles

During the past year the first beetles appeared in pasture droppings on November 4 when the dung peds had an average of 27 beetlespad On different weeks from November 11 through December 11 the density of ~ fimetarius remained fairly stable at 29 21 23 end 25 beetlespad As in previous years the beetle density then began to decline with 15pad on December 15 and less than one per pad on January 7 1982 In the Fall of 1981 beetles that had been marked and released into the experimental cages first appeared in the Scott 14 pasture on November 9 5 days after beetles first appeared in cattle dung pads in pastures The marked beetles contshyinued to appear in the Scott 14 cage through December with one beetle last appearing on December 16 No beetles were recovered in the Howarth pasture cage and through December 16 only 1 of marked beetles had been recovered in the Scott 14 cage This is in marked contrast to the cage recapture rates of 57 in the Scott pasture and 104 in the Howarth pasture It appears that beetles marked with the fluorescent dust suffershyed heavy mortality most of the marked beetles recovered had only a few particles of dust under the elytra or under the membraneous wings Nevertheless recapture of marked beetles confirmed that ~ fimetarius naturally hibernates (aestivates) in the ground for about 5 months in this part of California Other methods of marking beetles will be tested during the next seaSon

The objectives of this research were outlined in the 1980 report Many of the same trends observed in 1980 were repeated in 1981 Body weights of the cows were positively related to level of supplementation

(Table 1) The greatest effect was observed at the start of the breeding season where the difference between the unsupplemented and 25 times supplemented cows was nearly 100 kg

Weaning weight of the calves (Table 2) reflected the plane of nutrition of the cows Although weaning weights were enhanced by supplementation the largest differences in body weights occurred at the times the dams were mated Body weights of the calves reflected differential milk production of the cows

As in the previous year birth weight of the calves was not affected by plane of nutrition of the cows

6 Progress Report (Progress during report period toward reaching objectives of this research)

The major objectives of this research with Hereford cattle are (1) to determine if individual differences in mounting frequency by juvenile males correlate with individual differences in sexual motivation and performance as adults (2) to determine the degree of correlation between sexual behaviors and other biological traits (eg aggressive behavior semen characteristics hormone levels body size scrotal circumference) (3) to determine the function of mounting exshyperience on the development of sexual behavior and (4) to determine the role of penile stimulation on the development of sexual behavior

Over the last 4 years 78 bulls have been obtained from the SFRFS herd to investigate these questions Twenty-four male calves were brought to Davis from SFRFS in May 1981 to be used in studying objective 114 No observations were made on this group at the Field Station

Prior to 1981 all of our observations on juvenile mounting (Objectives 1 and 3) were made in confined situations where estrous heifers were provided as mountingstimuli and inter-animal contacts were frequent To determine the frequency of juvenile mounting in a more typical range environment 10 male and 9 female purebredHereford calves were observed between January 13 and March 22 1981 for a total of 40 hrs (29 different days) The calves ranged in age from 48 to 102 days (x = 80 days) at the start of observation A total of 394 calf observation hours were made on the 10 bull calves in the group and 749 calf hours on all 19 calves

Relative to our studies in confinement the rate of juvenile mounting in a typical range environment is very low A total of 15 mount intentions 12 mount attempts and 6 mounts (33 mount responses) were observed during the 40 hrs of observation Except for one mount intention all of the mounting activities were exhibited by bull calves The rate of mount responses was 0084 per bull calf per hour of observation Nearly all of the mounting behaviors were observed near the feed trough following feeding of supplements Supplemental feeding was terminated on February 25th and no sexual activity was observed among calves after that date

It was concluded that the mounting experience of 2-12 to 4-12 mo juvenilecalves in a ranqe environment is very limited

CO1tinued work in the Tea Garden Plot fairly well protected from deer has show~ reasonably good resul ts for only a few coni fer~ ad hardwoods The 100St

promising at present arc Monterey pine coast redwood and varieties of Pinus halepensis (brutia and eldarica) The most promising hardwoods to date are Eucalyptus globulus camaldulensis (2 variants) urnigera and grandis

In the lower Plot near the Yuba River deer and cattle damage al1d some porcupine debarking have greatly reduced the choice of species here The above pines Arizona cypress plus possibly tamarisk aphylla and coast redwood still appear promising

The North Plot after 3 years of trial plantings versus 4 for the other plots shows promising results for only Arizona cypress Eucalyptus grandis from 2 sources and tamarisk aphylla It is too early to rate the remainj~g species over-all survival rates of which are generally low

No fertilizer tablets have been applied to any of these plots because other factors limiting growth and survival appear more Important There was no serious rodent or insect damage noted in any of the 3 plots this past year and irrigation practices have been generally good probably supplying around 3 acre feet per growing season of about 6 months

It is now planned to establish semi-commercial plots of a minimum of 112 acre for each of at least 5 of the most promising species in another area of the Sierra Field Station

6 Progress Report (Progress during report perio toward reaching objectives of this research)

Development work continued in the Campbell Field A fall-1980 seeding of a perennia grass-legume pasture mixture on the new irrigated pasture areas was successful except for parts of some fields where irrigation water (surface flow) failed to reach In general the newly-installed irrigation system performed well

The following work was done on or related to the range fertilization study being conducted on the Forbes Flll44 series fields

a Soil samples were taken from each of the 16 fields Analyses will be made for P 5 Ca Mg K and pH

b In cooperation with M B Jones (HFS) field plots were established at eight locations (4 north-facing aspects 4 south-facing) A factorial design was used to compare 4 levels of N (as urea) and 4 levels of P (as low-S concentrated superphosphate) plus an exploratory for several combinations of NPS with two replications at each locati r

c Also in cooperation with M B Jones a greenhouse pot test was set up at the Hopland Field station with rate-element combinations to match those in the field plots using soil collected at the field locations for the eight replications The pots were seeded with a mixture of sub and rose clovers together with soft chess

d M R George and W J Clawson located sites for a grazing utilization study employing 10 x 10 exclosures

e A field-scale experiment with aerial application of nitrogen (as urea) at 0 40 80 and 120 kgha rates (two fields per replication two replications per treatment) is planned for fall 1982 following evaluation of the tests described above and results of a pre-experiment calibration grazing (with steers) beginning February 1982 Roy Hull J G Morris and R E Delmas are cooperators from the Department of Animal Science

f Using Sobrante-Las Posas soil collected at the SFRFS a study of effects of levels of single superphosphate with and without N and effects of fertiizer placement on emergence growth and nodulation of sub clover was completed at Davis- bull

6 Progress Report (Progress during report period toward reaching objectives of this research)

This is the third year in which numbers of infective parasite larvae on pasture has been assessed by placing 2 worm-free tracer calves on pasture at monthly intervals Since this is only one of several locations where these studies are being conducted not all laboratory analyses have been completedNevertheless studies over the three year period demonstrates the occurrence of infective nematode larvae on pastures is repetitive and predictable The season for the occurrence of disease producing numbers of various species differs little in such diverse regions as the San Joaquin Valley (Elk Grove) the East Slope of the Sierras (Susanville) or the Sierra Foothills (UCSFR) This studycorroborates the newly emerging concepts of safe and unsafe grazing periods The application of data from this study can be utilized in managerial decisions and thus in Integrated Pest (parasite) Control programs It is planned that trials designed to establish the value of these IPC programs will be initiated at several locations including UCSFR during the 1981-82 year

6 Progress Report (Progress during report period toward reaching objectives of this research)

Four pairs of 14 acre plots were established during the fall of 1979 The Blue Oak overstory of these paired plots was approximately 0 25 50 and 75 The tree overstory was removed from one set of four plots by February 15 1980 and 12 wire mesh igloo type cages were placed on all plots by December 1980 Cages were located under tree canopy (or former tree canopy) and in the open using a stratified random procedure with proportional allocation

During 1981 three successive clippings were taken from inside the wire cages to determine the total standing crop present on February 21 (early season) April 3 amp 4 (mid-season) and June 2 (late season)

Preliminary Results (1981)

Uncleared plots 25 50 and 75 overstory cover Standing crop at any season did not differ appreciably by overstory level (Fig 1) When compared with uncleared open (0 overstory cover) plots standing crop was significantly less in uncleared plots at late season but not at early and mid-season Overstory cover and standing crop are not significantly correlated for any season (Fig 2)

Cleared Plots 25 50 and 75 prior overstory cover Standing crop is positively correlated with prior overstory cover particularly when uncleared open (0 overstory cover) plots are included in the comparison (Fig 2)

Tree removal greatly increased standing crop at all three seasons of harvest for all overstory cover levels (Fig 1) When compared to uncleared plots of the same overstory cover level these increases were 100 early season 133 midshyseason and 80 late season

Efficacy of sall as a vehicle for selenium supplementatio~

4 Project Leader J G Morri 5 1 5 bull Period Covered QL sectL - 1L A by this Report mo yr mo yr

6 Progress Report (Progress during report period toward reaching objectives of this research)

This experiment was undertaken to assess the efficacy and safety of a salt selenium mixture for supplementing range cows

Approximately a years data have been obtained on two groups each of 19 mature Hereford cows grazing range and offered two salt-selenium mineral mixtures free choice The concentration of selenium in one mixture was 40 ppm (low Se group) and the other 80 ppm (high Se group) These levels represent 2 and 4 times the maximal level currently permitted by FDA

Blood selenium concentrations (Figure 1) were determined on each animal at weekly intervals initially then at monthy intervals Intake of the salt-selenium mixture was also measured at monthly intervals to obtain total group mean intake of selenium

Blood selenium concentration rose from the initial concentration of 0035 ~gml to a maxima of approximately 0225 ~gm1 in the high group and 0150 ~gm1 in the low group at about 12 weeks Then maximal concentrations are within the range of normality and in no way indicate selenium toxicity

Intake of the salt-selenium mixture was not well correlated with blood concentration of se1eniUffl

Then data indicate that the FDA maximal level of 20 ppm selenium in salt supplements is conservative and may be ineffectual in areas of selenium deficiency There was no significant difference in the weight of the cows at the time the calves were weaned - low group 487 ~ 48 kg high group - 481 ~ 57 kg

SlJotMARY OF COMMENTS

The foothills of California offer an ideal place for people

to pursue farming Farming in the tradi tional sense family cerltered

labor interlsive small machinery oriented conservation minded small

Hopefully the U C Sierra Foothill Range Field Station will accept

and meet the challenge of providing research and information appropriate

to the fledgling development of a foothill agriculture ethic in which

the quality of food and living is paramount Projects of this nature

are few in the 1981 annual report Possibly we can make II greeter

contribution to foothill farming in the future

The breeding program utilizing polled Hereford sires AI continues A polled Hereford bull from a production tested herd was obtained an performance data from the purebred cow ~erdmiddotcontinues Test data of weaner bull calves with the best calves selected for use in the Sierra herds also continues

Weaning weight of calves from the cow herds was lower by 40-50 1bs due to a very rough 1980-81 winter Range clearing continues along with increased use of the heifers reared at Sierra as replacements in the cow herds Studies utilizing the progeny of the Sierra cow herds continue at Davis These progeny were transshyferred to trials for the Animal Science Faculty as well as utilized for teachshying In addition other units of the University have use of progeny of the Sierra herds such as Veterinary Medicine Cooperative Extension Entomology etc

An experiment is being conducted to determine the feasibility of producing twin calves under range conditions This research is a continuation of similar research carried out on the UCD campus and is designed to study the production of twins under practical range conditions Beef females of low and high milk producing abilityHerefords and Hereford x Holstein crossbreds respectively were induced to producetwins by embryo transfer Dams are being maintained throughout pregnancy and lactation on irrigated pasture Birth and weaning weights of single and twin calves as well as complications such as calf mortality retained placentas dystocia are being recorded

Evaluation of Ectiban Formulations For Fly Control on Cattle U C Sierra Foothill Range Field Station California 1981

E C Loomis PhD Parasitologist Lorry L Dunning Staff Research Associate

Extension Veterinary Medicine University of California Davis 95616

INTRODUCTION

Sixty (60)- Hereford heifers (avg wt4Q0 lbs) maintained on irrigated pasture at the U C Field Station were used for a fly control trial using Ectiban Pour~On and~Ectiban insecticide Ear Tag Tapes The heifers were divided into 6 equal groups of 10 each and were identified as groups 1 to 6 Twenty-five heifers of similar age and weight were kept on dry rangeland about 12 mile distant and served as Group 7 for a control (untreated) All 85 heifers were rated for horn fly densities in corrals prior to group separation and treatment but face fly counts were made in the field one week later

MATERIALS AND PROCEDURES

Ectiban formulations for trial evaluation consisted of a ready-to-use 1 Permethrin Pour-On (GFU003 Red 6766 dated 32481) and I-gram active ingredient Permethrin Ear Tag tapes for application to cattle ear tags These formulations were compared to a standard registered 005 spray using Coopertox Extra (Toxaphene 45 Lindane 196gt

Ectiban Pour-On was applied by means of 4 oz capacity metal dippers to 4 groups at a dosage of 12 ozcwt initially on June 10 and retreated on August 3 Groups 1 and 4 received a backline application while groups 2 and 5 received a face and poll application Groups 3 and 6 were sprayed over the entire body on June 10 and only Group 6 W4S resprayed on September 30 using 12 gallon (70 ozgt of Coopertox solution per head from a U C power sprayer equipped with a 6 HP Briggs amp Stratton engine plus by-pass pump system operated at 300 psi

Ectiban Ear Tag tapes for ear tag application arrived midway through the trial and some of the groups were split for tape application when retreatment was indicated on September 2 Groups 2 and 3 received one tape per heifer attached around the neck of the ear tag and Group I had a tape wrapped around the _end of the tail (above the switch) and secured with adhesive duct tape Groups 4 to 6 were not retreated at this time in order to determine possible effects of fly control from Ectiban-taped heifers which shared common fence lines and

2

exposure with the 3 Groups Following observations on September 23 it was decided to retreat Groups 4 to 6 on September 30 using the same Pour-On and Spray regimen as applied at the start of the trial

Visual fly counts by eye or with the aid of 7 x 50 binoculars were made in most cases by one observer on all 10 heifers in each of 6 Groups and on 10 of the 25 heifers in control Group 7 Counts were made from lOAM to 2PM at weekly intervals Horn fly counts (H irritans) were made on flies resting on one side of the body (withers ribcage and upper legs) and on Face flies (M autumnalis) resting on the face and head area

O~e way analysis of variance was used to determine if overall trea-tment means varied significantly Fishers LSD method was used to compare where differences occurred between treatment means

RESULTS AND DISCUSSION

The results on Horn fly control are shown in Table 1 Excellent control was obtained for 4 weeks (June 10 to July 7) for Ectiban backline Pour-On to Groups 1 and 4 while excellent to good control resulted from Ectiban face Pour-on on Groups 2 and 5 for the same 4 weeks Coopertox spray on Groups 3 and 6 provided excellent control for only 2 weeks (June 10 to 24) Surprisingly retreatment of the 4 Ectiban groups on August 2 provided not more than 2 weeks of satisfactory control Of equal interest was the dramatic decrease in horn flies for two weeks on Group 3 but only slightly so on Group 6 both of which were intentionally not resprayed with Coopertox on August 2 There was no significant difference between Ectiban Pour-On to the backline or to the face nor between these treatments and the Coopertox body spray as determined from mean totals on Horn fly populations for the entire trial period June 10 to October 17 all three treatments reduced horn flies significantly better (P lt 0005) than the control (Table 3)

Also included in Table 1 are the results for horn fly control following Ectiban Tape applications on September 2 Excellent control resulted for 4 weeks on taped-heifers in Groups 1 2 and 3 No significant difference occurred between tape treatments to the ear or tail but all 3 treatment groups showed significant fly reduction (P lt 0005) when compared to the control group (Table 4) Fly populations in control Group 7 decreased rapidly with the onset of cold nights during the week of October 10

The results on Face fly control are shown in Table 2 Relatively good control of this species occurred with the Pour-On treatments for about 2 weeks (June 10 to 24) -with almost similar results for the Coopertox spray Fly control on these same groups retreated on August 3 provided a shorter

period of control about 9 to 1i days the natural dccro(1s(~ in Face fly popula tion s dur i ng Ju 1 and Augus t as ev idenct~d in Control Group 7 is commonplace and fly numbers are too low to warrant reliable comparison witn treated animals There was no significant difference between the Ectiban Pour-On to the face or to the backlinebut both treatments -were significantly different (P lt 0005) than the Coopertox spray and the control (Table 3)

Also included in Table 2 are the results for Face fly control following Ectiban tape applications on September 2 Excellent (Group 2) to good (Group 3) control resulted one day after application with tapes applied to ear tags but control did not persist at a satisfactory level as evidenced by the increase in fly counts on September 9 there was poor control via tapes attached to the tail (Group 1) The poor significance of these results are shown in Table 4 Poor results were obtained on face fly ~ontrol upon retreatment of Groups 41 and 50n September 30 and similar JesuIts were evident on Group 6 which was resprayed wi th Co_opertlt~

Of interest in this trial were the results on Horn fly control from the small amount of Ectiban Pour-On to the face of animals Heretofore it was believed that a similar dose of a pesticide to the withers was more effective but if Face fly populations are the main target then face and head applications could serve a dual purpose to include Horn fly control

Early IrrIgation - Liquid Supplement Trial

RIck Delmas

This study was initiated In 1980 to study the performance of

cattle using liquid supplement and the effect of early irrigation of

annual grasslands for early fall growth on the performance of cattle

during the fall and winter grazing period

Though the trial needs to be continued for the next couple of

years the following are indicated from one years data

1) Early irrigation furnishes valuable early fall feed especially

in poor rainfall years

2) Liquid supplement doesnt appear to be as beneficial as concentrates

for young cattle during the fall and winter The conception rate

on cattle with only liquid supplement was 8 to 19 lower than on

the other three treatments Economically the liquid supplement

was half the cost or less of the concentrate excluding labor

From this sfandpoint alone a rancher may be wIlling to accept

a slightly lower conception rate to obtain the decreased labor

and supplement cost Each individual rancher must measure cost

versus production

EFFECT OF OAK TREE REMOVAL ON FORAGE PRODUCTION

1981 was the sixteenth year that forage production has been measured in this study I have considered terminating the measurements because yield increases have not been significant in three of the last four years (see table) However data show that increases were significant in all of the sixteen years in which forage production on the check treatment (area covered by live trees) was below the median of the period (1385 Ibacre) Therefore in the interest of economy only the check treatments will be sampled in high rainfall years If another poor feed year occurs soon we will measure all treatments

6 Progress Report (Progress uring report perio toward reaching objectives of this research) The Ecologv and Population Dynamics of Aphodius fimetarius

The ecological study of the dung beetle Aphodius fimetarius was continued by again monitoring the ability of males and females to hibshyernate (aestivate) from late Spring to Fall From May 29 through June 9 we collected and marked 3020 beetles with fluorescent dust Half of these were released into a beetle-proof screened field cage in the Scott 14 pasture and the other half were released into a s~milar cage at the Howarth pasture o Both cages enclosed about 30 ft of natural turf and each was supplied with fresh dung (beetle food) until no beetles were present These two cages were monitored for the re-eppearance of beetles from September through December and cattle droppings from various pastures were sampled for the presence of naturally appearing wild beetles

During the past year the first beetles appeared in pasture droppings on November 4 when the dung peds had an average of 27 beetlespad On different weeks from November 11 through December 11 the density of ~ fimetarius remained fairly stable at 29 21 23 end 25 beetlespad As in previous years the beetle density then began to decline with 15pad on December 15 and less than one per pad on January 7 1982 In the Fall of 1981 beetles that had been marked and released into the experimental cages first appeared in the Scott 14 pasture on November 9 5 days after beetles first appeared in cattle dung pads in pastures The marked beetles contshyinued to appear in the Scott 14 cage through December with one beetle last appearing on December 16 No beetles were recovered in the Howarth pasture cage and through December 16 only 1 of marked beetles had been recovered in the Scott 14 cage This is in marked contrast to the cage recapture rates of 57 in the Scott pasture and 104 in the Howarth pasture It appears that beetles marked with the fluorescent dust suffershyed heavy mortality most of the marked beetles recovered had only a few particles of dust under the elytra or under the membraneous wings Nevertheless recapture of marked beetles confirmed that ~ fimetarius naturally hibernates (aestivates) in the ground for about 5 months in this part of California Other methods of marking beetles will be tested during the next seaSon

The objectives of this research were outlined in the 1980 report Many of the same trends observed in 1980 were repeated in 1981 Body weights of the cows were positively related to level of supplementation

(Table 1) The greatest effect was observed at the start of the breeding season where the difference between the unsupplemented and 25 times supplemented cows was nearly 100 kg

Weaning weight of the calves (Table 2) reflected the plane of nutrition of the cows Although weaning weights were enhanced by supplementation the largest differences in body weights occurred at the times the dams were mated Body weights of the calves reflected differential milk production of the cows

As in the previous year birth weight of the calves was not affected by plane of nutrition of the cows

6 Progress Report (Progress during report period toward reaching objectives of this research)

The major objectives of this research with Hereford cattle are (1) to determine if individual differences in mounting frequency by juvenile males correlate with individual differences in sexual motivation and performance as adults (2) to determine the degree of correlation between sexual behaviors and other biological traits (eg aggressive behavior semen characteristics hormone levels body size scrotal circumference) (3) to determine the function of mounting exshyperience on the development of sexual behavior and (4) to determine the role of penile stimulation on the development of sexual behavior

Over the last 4 years 78 bulls have been obtained from the SFRFS herd to investigate these questions Twenty-four male calves were brought to Davis from SFRFS in May 1981 to be used in studying objective 114 No observations were made on this group at the Field Station

Prior to 1981 all of our observations on juvenile mounting (Objectives 1 and 3) were made in confined situations where estrous heifers were provided as mountingstimuli and inter-animal contacts were frequent To determine the frequency of juvenile mounting in a more typical range environment 10 male and 9 female purebredHereford calves were observed between January 13 and March 22 1981 for a total of 40 hrs (29 different days) The calves ranged in age from 48 to 102 days (x = 80 days) at the start of observation A total of 394 calf observation hours were made on the 10 bull calves in the group and 749 calf hours on all 19 calves

Relative to our studies in confinement the rate of juvenile mounting in a typical range environment is very low A total of 15 mount intentions 12 mount attempts and 6 mounts (33 mount responses) were observed during the 40 hrs of observation Except for one mount intention all of the mounting activities were exhibited by bull calves The rate of mount responses was 0084 per bull calf per hour of observation Nearly all of the mounting behaviors were observed near the feed trough following feeding of supplements Supplemental feeding was terminated on February 25th and no sexual activity was observed among calves after that date

It was concluded that the mounting experience of 2-12 to 4-12 mo juvenilecalves in a ranqe environment is very limited

promising at present arc Monterey pine coast redwood and varieties of Pinus halepensis (brutia and eldarica) The most promising hardwoods to date are Eucalyptus globulus camaldulensis (2 variants) urnigera and grandis

In the lower Plot near the Yuba River deer and cattle damage al1d some porcupine debarking have greatly reduced the choice of species here The above pines Arizona cypress plus possibly tamarisk aphylla and coast redwood still appear promising

The North Plot after 3 years of trial plantings versus 4 for the other plots shows promising results for only Arizona cypress Eucalyptus grandis from 2 sources and tamarisk aphylla It is too early to rate the remainj~g species over-all survival rates of which are generally low

No fertilizer tablets have been applied to any of these plots because other factors limiting growth and survival appear more Important There was no serious rodent or insect damage noted in any of the 3 plots this past year and irrigation practices have been generally good probably supplying around 3 acre feet per growing season of about 6 months

It is now planned to establish semi-commercial plots of a minimum of 112 acre for each of at least 5 of the most promising species in another area of the Sierra Field Station

Development work continued in the Campbell Field A fall-1980 seeding of a perennia grass-legume pasture mixture on the new irrigated pasture areas was successful except for parts of some fields where irrigation water (surface flow) failed to reach In general the newly-installed irrigation system performed well

The following work was done on or related to the range fertilization study being conducted on the Forbes Flll44 series fields

a Soil samples were taken from each of the 16 fields Analyses will be made for P 5 Ca Mg K and pH

b In cooperation with M B Jones (HFS) field plots were established at eight locations (4 north-facing aspects 4 south-facing) A factorial design was used to compare 4 levels of N (as urea) and 4 levels of P (as low-S concentrated superphosphate) plus an exploratory for several combinations of NPS with two replications at each locati r

c Also in cooperation with M B Jones a greenhouse pot test was set up at the Hopland Field station with rate-element combinations to match those in the field plots using soil collected at the field locations for the eight replications The pots were seeded with a mixture of sub and rose clovers together with soft chess

d M R George and W J Clawson located sites for a grazing utilization study employing 10 x 10 exclosures

6 Progress Report (Progress during report period toward reaching objectives of this research)

Four pairs of 14 acre plots were established during the fall of 1979 The Blue Oak overstory of these paired plots was approximately 0 25 50 and 75 The tree overstory was removed from one set of four plots by February 15 1980 and 12 wire mesh igloo type cages were placed on all plots by December 1980 Cages were located under tree canopy (or former tree canopy) and in the open using a stratified random procedure with proportional allocation

During 1981 three successive clippings were taken from inside the wire cages to determine the total standing crop present on February 21 (early season) April 3 amp 4 (mid-season) and June 2 (late season)

Preliminary Results (1981)

Uncleared plots 25 50 and 75 overstory cover Standing crop at any season did not differ appreciably by overstory level (Fig 1) When compared with uncleared open (0 overstory cover) plots standing crop was significantly less in uncleared plots at late season but not at early and mid-season Overstory cover and standing crop are not significantly correlated for any season (Fig 2)

Cleared Plots 25 50 and 75 prior overstory cover Standing crop is positively correlated with prior overstory cover particularly when uncleared open (0 overstory cover) plots are included in the comparison (Fig 2)

Tree removal greatly increased standing crop at all three seasons of harvest for all overstory cover levels (Fig 1) When compared to uncleared plots of the same overstory cover level these increases were 100 early season 133 midshyseason and 80 late season

this research)

During the first phase of the trial we are observing tropical plants Varieties were I isted in last year1s report The Leucaena species was eliminated Last winter was a relatively mild winter thus we feel we did not obtain good cold readings on the other species Further observations will be made this coming year

In the second phase we have planted species and varieties of Orchardgrass Tall Fescue and Perennial Ryegrass from the Georgia Plant Station In addition planted species of the same plants used in California irrigated pastures Stand evaluations were made on all species this past year only This coming year we will obtain yield data

6 Progress Report (Progress during report perlod toward reaching objectives of this research)

The major objective of this study is to determine differences in the maternal care provided tw1n calves relative to the maternal behavior of cows with singleoffspring when placed 1n a range environment Observations were conducted duringJanuary February and March 1981 at SFRFS on 7 cows with single calves and 5 cows with twins housed in a 75A pasture The animals were observed for 15 hrs per week during the f1rst two hrs following sunrise and the two hrs preceding sunset

Data collected on mothers included frequency and duration of licking (grooming) calves vocalizattons butts and butt attempts directed at alien calves and behavioral responses to separatton from calf(ves) Calves were observed for frequency and duration of sucking on own and aUen mothers frequency and duration of resting runn1ng laying and grazing frequency of vocalizations and juvenilemounting and prox1m1ty to mother tw1n and nea~est unrelated calf

The data have been compiled but have not yet been analyzed statistically

Efficacy of sall as a vehicle for selenium supplementatio~

4 Project Leader J G Morri 5 1 5 bull Period Covered QL sectL - 1L A by this Report mo yr mo yr

6 Progress Report (Progress during report period toward reaching objectives of this research)

This experiment was undertaken to assess the efficacy and safety of a salt selenium mixture for supplementing range cows

Approximately a years data have been obtained on two groups each of 19 mature Hereford cows grazing range and offered two salt-selenium mineral mixtures free choice The concentration of selenium in one mixture was 40 ppm (low Se group) and the other 80 ppm (high Se group) These levels represent 2 and 4 times the maximal level currently permitted by FDA

Blood selenium concentrations (Figure 1) were determined on each animal at weekly intervals initially then at monthy intervals Intake of the salt-selenium mixture was also measured at monthly intervals to obtain total group mean intake of selenium

Blood selenium concentration rose from the initial concentration of 0035 ~gml to a maxima of approximately 0225 ~gm1 in the high group and 0150 ~gm1 in the low group at about 12 weeks Then maximal concentrations are within the range of normality and in no way indicate selenium toxicity

Intake of the salt-selenium mixture was not well correlated with blood concentration of se1eniUffl

Then data indicate that the FDA maximal level of 20 ppm selenium in salt supplements is conservative and may be ineffectual in areas of selenium deficiency There was no significant difference in the weight of the cows at the time the calves were weaned - low group 487 ~ 48 kg high group - 481 ~ 57 kg

SlJotMARY OF COMMENTS

The foothills of California offer an ideal place for people

to pursue farming Farming in the tradi tional sense family cerltered

labor interlsive small machinery oriented conservation minded small

Hopefully the U C Sierra Foothill Range Field Station will accept

and meet the challenge of providing research and information appropriate

to the fledgling development of a foothill agriculture ethic in which

the quality of food and living is paramount Projects of this nature

are few in the 1981 annual report Possibly we can make II greeter

contribution to foothill farming in the future

Evaluation of Ectiban Formulations For Fly Control on Cattle U C Sierra Foothill Range Field Station California 1981

E C Loomis PhD Parasitologist Lorry L Dunning Staff Research Associate

Extension Veterinary Medicine University of California Davis 95616

INTRODUCTION

Sixty (60)- Hereford heifers (avg wt4Q0 lbs) maintained on irrigated pasture at the U C Field Station were used for a fly control trial using Ectiban Pour~On and~Ectiban insecticide Ear Tag Tapes The heifers were divided into 6 equal groups of 10 each and were identified as groups 1 to 6 Twenty-five heifers of similar age and weight were kept on dry rangeland about 12 mile distant and served as Group 7 for a control (untreated) All 85 heifers were rated for horn fly densities in corrals prior to group separation and treatment but face fly counts were made in the field one week later

MATERIALS AND PROCEDURES

Ectiban formulations for trial evaluation consisted of a ready-to-use 1 Permethrin Pour-On (GFU003 Red 6766 dated 32481) and I-gram active ingredient Permethrin Ear Tag tapes for application to cattle ear tags These formulations were compared to a standard registered 005 spray using Coopertox Extra (Toxaphene 45 Lindane 196gt

Ectiban Pour-On was applied by means of 4 oz capacity metal dippers to 4 groups at a dosage of 12 ozcwt initially on June 10 and retreated on August 3 Groups 1 and 4 received a backline application while groups 2 and 5 received a face and poll application Groups 3 and 6 were sprayed over the entire body on June 10 and only Group 6 W4S resprayed on September 30 using 12 gallon (70 ozgt of Coopertox solution per head from a U C power sprayer equipped with a 6 HP Briggs amp Stratton engine plus by-pass pump system operated at 300 psi

Ectiban Ear Tag tapes for ear tag application arrived midway through the trial and some of the groups were split for tape application when retreatment was indicated on September 2 Groups 2 and 3 received one tape per heifer attached around the neck of the ear tag and Group I had a tape wrapped around the _end of the tail (above the switch) and secured with adhesive duct tape Groups 4 to 6 were not retreated at this time in order to determine possible effects of fly control from Ectiban-taped heifers which shared common fence lines and

2

exposure with the 3 Groups Following observations on September 23 it was decided to retreat Groups 4 to 6 on September 30 using the same Pour-On and Spray regimen as applied at the start of the trial

Visual fly counts by eye or with the aid of 7 x 50 binoculars were made in most cases by one observer on all 10 heifers in each of 6 Groups and on 10 of the 25 heifers in control Group 7 Counts were made from lOAM to 2PM at weekly intervals Horn fly counts (H irritans) were made on flies resting on one side of the body (withers ribcage and upper legs) and on Face flies (M autumnalis) resting on the face and head area

O~e way analysis of variance was used to determine if overall trea-tment means varied significantly Fishers LSD method was used to compare where differences occurred between treatment means

RESULTS AND DISCUSSION

The results on Horn fly control are shown in Table 1 Excellent control was obtained for 4 weeks (June 10 to July 7) for Ectiban backline Pour-On to Groups 1 and 4 while excellent to good control resulted from Ectiban face Pour-on on Groups 2 and 5 for the same 4 weeks Coopertox spray on Groups 3 and 6 provided excellent control for only 2 weeks (June 10 to 24) Surprisingly retreatment of the 4 Ectiban groups on August 2 provided not more than 2 weeks of satisfactory control Of equal interest was the dramatic decrease in horn flies for two weeks on Group 3 but only slightly so on Group 6 both of which were intentionally not resprayed with Coopertox on August 2 There was no significant difference between Ectiban Pour-On to the backline or to the face nor between these treatments and the Coopertox body spray as determined from mean totals on Horn fly populations for the entire trial period June 10 to October 17 all three treatments reduced horn flies significantly better (P lt 0005) than the control (Table 3)

Also included in Table 1 are the results for horn fly control following Ectiban Tape applications on September 2 Excellent control resulted for 4 weeks on taped-heifers in Groups 1 2 and 3 No significant difference occurred between tape treatments to the ear or tail but all 3 treatment groups showed significant fly reduction (P lt 0005) when compared to the control group (Table 4) Fly populations in control Group 7 decreased rapidly with the onset of cold nights during the week of October 10

The results on Face fly control are shown in Table 2 Relatively good control of this species occurred with the Pour-On treatments for about 2 weeks (June 10 to 24) -with almost similar results for the Coopertox spray Fly control on these same groups retreated on August 3 provided a shorter

period of control about 9 to 1i days the natural dccro(1s(~ in Face fly popula tion s dur i ng Ju 1 and Augus t as ev idenct~d in Control Group 7 is commonplace and fly numbers are too low to warrant reliable comparison witn treated animals There was no significant difference between the Ectiban Pour-On to the face or to the backlinebut both treatments -were significantly different (P lt 0005) than the Coopertox spray and the control (Table 3)

Also included in Table 2 are the results for Face fly control following Ectiban tape applications on September 2 Excellent (Group 2) to good (Group 3) control resulted one day after application with tapes applied to ear tags but control did not persist at a satisfactory level as evidenced by the increase in fly counts on September 9 there was poor control via tapes attached to the tail (Group 1) The poor significance of these results are shown in Table 4 Poor results were obtained on face fly ~ontrol upon retreatment of Groups 41 and 50n September 30 and similar JesuIts were evident on Group 6 which was resprayed wi th Co_opertlt~

Of interest in this trial were the results on Horn fly control from the small amount of Ectiban Pour-On to the face of animals Heretofore it was believed that a similar dose of a pesticide to the withers was more effective but if Face fly populations are the main target then face and head applications could serve a dual purpose to include Horn fly control

Early IrrIgation - Liquid Supplement Trial

RIck Delmas

This study was initiated In 1980 to study the performance of

cattle using liquid supplement and the effect of early irrigation of

annual grasslands for early fall growth on the performance of cattle

during the fall and winter grazing period

Though the trial needs to be continued for the next couple of

years the following are indicated from one years data

1) Early irrigation furnishes valuable early fall feed especially

in poor rainfall years

2) Liquid supplement doesnt appear to be as beneficial as concentrates

for young cattle during the fall and winter The conception rate

on cattle with only liquid supplement was 8 to 19 lower than on

the other three treatments Economically the liquid supplement

was half the cost or less of the concentrate excluding labor

From this sfandpoint alone a rancher may be wIlling to accept

a slightly lower conception rate to obtain the decreased labor

and supplement cost Each individual rancher must measure cost

versus production

EFFECT OF OAK TREE REMOVAL ON FORAGE PRODUCTION

1981 was the sixteenth year that forage production has been measured in this study I have considered terminating the measurements because yield increases have not been significant in three of the last four years (see table) However data show that increases were significant in all of the sixteen years in which forage production on the check treatment (area covered by live trees) was below the median of the period (1385 Ibacre) Therefore in the interest of economy only the check treatments will be sampled in high rainfall years If another poor feed year occurs soon we will measure all treatments

6 Progress Report (Progress uring report perio toward reaching objectives of this research) The Ecologv and Population Dynamics of Aphodius fimetarius

The ecological study of the dung beetle Aphodius fimetarius was continued by again monitoring the ability of males and females to hibshyernate (aestivate) from late Spring to Fall From May 29 through June 9 we collected and marked 3020 beetles with fluorescent dust Half of these were released into a beetle-proof screened field cage in the Scott 14 pasture and the other half were released into a s~milar cage at the Howarth pasture o Both cages enclosed about 30 ft of natural turf and each was supplied with fresh dung (beetle food) until no beetles were present These two cages were monitored for the re-eppearance of beetles from September through December and cattle droppings from various pastures were sampled for the presence of naturally appearing wild beetles

During the past year the first beetles appeared in pasture droppings on November 4 when the dung peds had an average of 27 beetlespad On different weeks from November 11 through December 11 the density of ~ fimetarius remained fairly stable at 29 21 23 end 25 beetlespad As in previous years the beetle density then began to decline with 15pad on December 15 and less than one per pad on January 7 1982 In the Fall of 1981 beetles that had been marked and released into the experimental cages first appeared in the Scott 14 pasture on November 9 5 days after beetles first appeared in cattle dung pads in pastures The marked beetles contshyinued to appear in the Scott 14 cage through December with one beetle last appearing on December 16 No beetles were recovered in the Howarth pasture cage and through December 16 only 1 of marked beetles had been recovered in the Scott 14 cage This is in marked contrast to the cage recapture rates of 57 in the Scott pasture and 104 in the Howarth pasture It appears that beetles marked with the fluorescent dust suffershyed heavy mortality most of the marked beetles recovered had only a few particles of dust under the elytra or under the membraneous wings Nevertheless recapture of marked beetles confirmed that ~ fimetarius naturally hibernates (aestivates) in the ground for about 5 months in this part of California Other methods of marking beetles will be tested during the next seaSon

The objectives of this research were outlined in the 1980 report Many of the same trends observed in 1980 were repeated in 1981 Body weights of the cows were positively related to level of supplementation

(Table 1) The greatest effect was observed at the start of the breeding season where the difference between the unsupplemented and 25 times supplemented cows was nearly 100 kg

Weaning weight of the calves (Table 2) reflected the plane of nutrition of the cows Although weaning weights were enhanced by supplementation the largest differences in body weights occurred at the times the dams were mated Body weights of the calves reflected differential milk production of the cows

As in the previous year birth weight of the calves was not affected by plane of nutrition of the cows

6 Progress Report (Progress during report period toward reaching objectives of this research)

The major objectives of this research with Hereford cattle are (1) to determine if individual differences in mounting frequency by juvenile males correlate with individual differences in sexual motivation and performance as adults (2) to determine the degree of correlation between sexual behaviors and other biological traits (eg aggressive behavior semen characteristics hormone levels body size scrotal circumference) (3) to determine the function of mounting exshyperience on the development of sexual behavior and (4) to determine the role of penile stimulation on the development of sexual behavior

Over the last 4 years 78 bulls have been obtained from the SFRFS herd to investigate these questions Twenty-four male calves were brought to Davis from SFRFS in May 1981 to be used in studying objective 114 No observations were made on this group at the Field Station

Prior to 1981 all of our observations on juvenile mounting (Objectives 1 and 3) were made in confined situations where estrous heifers were provided as mountingstimuli and inter-animal contacts were frequent To determine the frequency of juvenile mounting in a more typical range environment 10 male and 9 female purebredHereford calves were observed between January 13 and March 22 1981 for a total of 40 hrs (29 different days) The calves ranged in age from 48 to 102 days (x = 80 days) at the start of observation A total of 394 calf observation hours were made on the 10 bull calves in the group and 749 calf hours on all 19 calves

Relative to our studies in confinement the rate of juvenile mounting in a typical range environment is very low A total of 15 mount intentions 12 mount attempts and 6 mounts (33 mount responses) were observed during the 40 hrs of observation Except for one mount intention all of the mounting activities were exhibited by bull calves The rate of mount responses was 0084 per bull calf per hour of observation Nearly all of the mounting behaviors were observed near the feed trough following feeding of supplements Supplemental feeding was terminated on February 25th and no sexual activity was observed among calves after that date

It was concluded that the mounting experience of 2-12 to 4-12 mo juvenilecalves in a ranqe environment is very limited

In the lower Plot near the Yuba River deer and cattle damage al1d some porcupine debarking have greatly reduced the choice of species here The above pines Arizona cypress plus possibly tamarisk aphylla and coast redwood still appear promising

The North Plot after 3 years of trial plantings versus 4 for the other plots shows promising results for only Arizona cypress Eucalyptus grandis from 2 sources and tamarisk aphylla It is too early to rate the remainj~g species over-all survival rates of which are generally low

No fertilizer tablets have been applied to any of these plots because other factors limiting growth and survival appear more Important There was no serious rodent or insect damage noted in any of the 3 plots this past year and irrigation practices have been generally good probably supplying around 3 acre feet per growing season of about 6 months

It is now planned to establish semi-commercial plots of a minimum of 112 acre for each of at least 5 of the most promising species in another area of the Sierra Field Station

Development work continued in the Campbell Field A fall-1980 seeding of a perennia grass-legume pasture mixture on the new irrigated pasture areas was successful except for parts of some fields where irrigation water (surface flow) failed to reach In general the newly-installed irrigation system performed well

The following work was done on or related to the range fertilization study being conducted on the Forbes Flll44 series fields

a Soil samples were taken from each of the 16 fields Analyses will be made for P 5 Ca Mg K and pH

b In cooperation with M B Jones (HFS) field plots were established at eight locations (4 north-facing aspects 4 south-facing) A factorial design was used to compare 4 levels of N (as urea) and 4 levels of P (as low-S concentrated superphosphate) plus an exploratory for several combinations of NPS with two replications at each locati r

c Also in cooperation with M B Jones a greenhouse pot test was set up at the Hopland Field station with rate-element combinations to match those in the field plots using soil collected at the field locations for the eight replications The pots were seeded with a mixture of sub and rose clovers together with soft chess

6 Progress Report (Progress during report period toward reaching objectives of this research)

Four pairs of 14 acre plots were established during the fall of 1979 The Blue Oak overstory of these paired plots was approximately 0 25 50 and 75 The tree overstory was removed from one set of four plots by February 15 1980 and 12 wire mesh igloo type cages were placed on all plots by December 1980 Cages were located under tree canopy (or former tree canopy) and in the open using a stratified random procedure with proportional allocation

During 1981 three successive clippings were taken from inside the wire cages to determine the total standing crop present on February 21 (early season) April 3 amp 4 (mid-season) and June 2 (late season)

Preliminary Results (1981)

Uncleared plots 25 50 and 75 overstory cover Standing crop at any season did not differ appreciably by overstory level (Fig 1) When compared with uncleared open (0 overstory cover) plots standing crop was significantly less in uncleared plots at late season but not at early and mid-season Overstory cover and standing crop are not significantly correlated for any season (Fig 2)

Cleared Plots 25 50 and 75 prior overstory cover Standing crop is positively correlated with prior overstory cover particularly when uncleared open (0 overstory cover) plots are included in the comparison (Fig 2)

Tree removal greatly increased standing crop at all three seasons of harvest for all overstory cover levels (Fig 1) When compared to uncleared plots of the same overstory cover level these increases were 100 early season 133 midshyseason and 80 late season

6 Progress Report (Progress during report period toward reaching objectives of this research)

This experiment was undertaken to assess the efficacy and safety of a salt selenium mixture for supplementing range cows

Approximately a years data have been obtained on two groups each of 19 mature Hereford cows grazing range and offered two salt-selenium mineral mixtures free choice The concentration of selenium in one mixture was 40 ppm (low Se group) and the other 80 ppm (high Se group) These levels represent 2 and 4 times the maximal level currently permitted by FDA

Blood selenium concentrations (Figure 1) were determined on each animal at weekly intervals initially then at monthy intervals Intake of the salt-selenium mixture was also measured at monthly intervals to obtain total group mean intake of selenium

Blood selenium concentration rose from the initial concentration of 0035 ~gml to a maxima of approximately 0225 ~gm1 in the high group and 0150 ~gm1 in the low group at about 12 weeks Then maximal concentrations are within the range of normality and in no way indicate selenium toxicity

Intake of the salt-selenium mixture was not well correlated with blood concentration of se1eniUffl

Then data indicate that the FDA maximal level of 20 ppm selenium in salt supplements is conservative and may be ineffectual in areas of selenium deficiency There was no significant difference in the weight of the cows at the time the calves were weaned - low group 487 ~ 48 kg high group - 481 ~ 57 kg

SlJotMARY OF COMMENTS

The foothills of California offer an ideal place for people

to pursue farming Farming in the tradi tional sense family cerltered

labor interlsive small machinery oriented conservation minded small

Hopefully the U C Sierra Foothill Range Field Station will accept

and meet the challenge of providing research and information appropriate

to the fledgling development of a foothill agriculture ethic in which

the quality of food and living is paramount Projects of this nature

are few in the 1981 annual report Possibly we can make II greeter

contribution to foothill farming in the future

The breeding program utilizing polled Hereford sires AI continues A polled Hereford bull from a production tested herd was obtained an performance data from the purebred cow ~erdmiddotcontinues Test data of weaner bull calves with the best calves selected for use in the Sierra herds also continues

Weaning weight of calves from the cow herds was lower by 40-50 1bs due to a very rough 1980-81 winter Range clearing continues along with increased use of the heifers reared at Sierra as replacements in the cow herds Studies utilizing the progeny of the Sierra cow herds continue at Davis These progeny were transshyferred to trials for the Animal Science Faculty as well as utilized for teachshying In addition other units of the University have use of progeny of the Sierra herds such as Veterinary Medicine Cooperative Extension Entomology etc

An experiment is being conducted to determine the feasibility of producing twin calves under range conditions This research is a continuation of similar research carried out on the UCD campus and is designed to study the production of twins under practical range conditions Beef females of low and high milk producing abilityHerefords and Hereford x Holstein crossbreds respectively were induced to producetwins by embryo transfer Dams are being maintained throughout pregnancy and lactation on irrigated pasture Birth and weaning weights of single and twin calves as well as complications such as calf mortality retained placentas dystocia are being recorded

Evaluation of Ectiban Formulations For Fly Control on Cattle U C Sierra Foothill Range Field Station California 1981

E C Loomis PhD Parasitologist Lorry L Dunning Staff Research Associate

Extension Veterinary Medicine University of California Davis 95616

INTRODUCTION

Sixty (60)- Hereford heifers (avg wt4Q0 lbs) maintained on irrigated pasture at the U C Field Station were used for a fly control trial using Ectiban Pour~On and~Ectiban insecticide Ear Tag Tapes The heifers were divided into 6 equal groups of 10 each and were identified as groups 1 to 6 Twenty-five heifers of similar age and weight were kept on dry rangeland about 12 mile distant and served as Group 7 for a control (untreated) All 85 heifers were rated for horn fly densities in corrals prior to group separation and treatment but face fly counts were made in the field one week later

MATERIALS AND PROCEDURES

Ectiban formulations for trial evaluation consisted of a ready-to-use 1 Permethrin Pour-On (GFU003 Red 6766 dated 32481) and I-gram active ingredient Permethrin Ear Tag tapes for application to cattle ear tags These formulations were compared to a standard registered 005 spray using Coopertox Extra (Toxaphene 45 Lindane 196gt

Ectiban Pour-On was applied by means of 4 oz capacity metal dippers to 4 groups at a dosage of 12 ozcwt initially on June 10 and retreated on August 3 Groups 1 and 4 received a backline application while groups 2 and 5 received a face and poll application Groups 3 and 6 were sprayed over the entire body on June 10 and only Group 6 W4S resprayed on September 30 using 12 gallon (70 ozgt of Coopertox solution per head from a U C power sprayer equipped with a 6 HP Briggs amp Stratton engine plus by-pass pump system operated at 300 psi

Ectiban Ear Tag tapes for ear tag application arrived midway through the trial and some of the groups were split for tape application when retreatment was indicated on September 2 Groups 2 and 3 received one tape per heifer attached around the neck of the ear tag and Group I had a tape wrapped around the _end of the tail (above the switch) and secured with adhesive duct tape Groups 4 to 6 were not retreated at this time in order to determine possible effects of fly control from Ectiban-taped heifers which shared common fence lines and

2

exposure with the 3 Groups Following observations on September 23 it was decided to retreat Groups 4 to 6 on September 30 using the same Pour-On and Spray regimen as applied at the start of the trial

Visual fly counts by eye or with the aid of 7 x 50 binoculars were made in most cases by one observer on all 10 heifers in each of 6 Groups and on 10 of the 25 heifers in control Group 7 Counts were made from lOAM to 2PM at weekly intervals Horn fly counts (H irritans) were made on flies resting on one side of the body (withers ribcage and upper legs) and on Face flies (M autumnalis) resting on the face and head area

O~e way analysis of variance was used to determine if overall trea-tment means varied significantly Fishers LSD method was used to compare where differences occurred between treatment means

RESULTS AND DISCUSSION

The results on Horn fly control are shown in Table 1 Excellent control was obtained for 4 weeks (June 10 to July 7) for Ectiban backline Pour-On to Groups 1 and 4 while excellent to good control resulted from Ectiban face Pour-on on Groups 2 and 5 for the same 4 weeks Coopertox spray on Groups 3 and 6 provided excellent control for only 2 weeks (June 10 to 24) Surprisingly retreatment of the 4 Ectiban groups on August 2 provided not more than 2 weeks of satisfactory control Of equal interest was the dramatic decrease in horn flies for two weeks on Group 3 but only slightly so on Group 6 both of which were intentionally not resprayed with Coopertox on August 2 There was no significant difference between Ectiban Pour-On to the backline or to the face nor between these treatments and the Coopertox body spray as determined from mean totals on Horn fly populations for the entire trial period June 10 to October 17 all three treatments reduced horn flies significantly better (P lt 0005) than the control (Table 3)

Also included in Table 1 are the results for horn fly control following Ectiban Tape applications on September 2 Excellent control resulted for 4 weeks on taped-heifers in Groups 1 2 and 3 No significant difference occurred between tape treatments to the ear or tail but all 3 treatment groups showed significant fly reduction (P lt 0005) when compared to the control group (Table 4) Fly populations in control Group 7 decreased rapidly with the onset of cold nights during the week of October 10

The results on Face fly control are shown in Table 2 Relatively good control of this species occurred with the Pour-On treatments for about 2 weeks (June 10 to 24) -with almost similar results for the Coopertox spray Fly control on these same groups retreated on August 3 provided a shorter

period of control about 9 to 1i days the natural dccro(1s(~ in Face fly popula tion s dur i ng Ju 1 and Augus t as ev idenct~d in Control Group 7 is commonplace and fly numbers are too low to warrant reliable comparison witn treated animals There was no significant difference between the Ectiban Pour-On to the face or to the backlinebut both treatments -were significantly different (P lt 0005) than the Coopertox spray and the control (Table 3)

Also included in Table 2 are the results for Face fly control following Ectiban tape applications on September 2 Excellent (Group 2) to good (Group 3) control resulted one day after application with tapes applied to ear tags but control did not persist at a satisfactory level as evidenced by the increase in fly counts on September 9 there was poor control via tapes attached to the tail (Group 1) The poor significance of these results are shown in Table 4 Poor results were obtained on face fly ~ontrol upon retreatment of Groups 41 and 50n September 30 and similar JesuIts were evident on Group 6 which was resprayed wi th Co_opertlt~

Of interest in this trial were the results on Horn fly control from the small amount of Ectiban Pour-On to the face of animals Heretofore it was believed that a similar dose of a pesticide to the withers was more effective but if Face fly populations are the main target then face and head applications could serve a dual purpose to include Horn fly control

Early IrrIgation - Liquid Supplement Trial

RIck Delmas

This study was initiated In 1980 to study the performance of

cattle using liquid supplement and the effect of early irrigation of

annual grasslands for early fall growth on the performance of cattle

during the fall and winter grazing period

Though the trial needs to be continued for the next couple of

years the following are indicated from one years data

1) Early irrigation furnishes valuable early fall feed especially

in poor rainfall years

2) Liquid supplement doesnt appear to be as beneficial as concentrates

for young cattle during the fall and winter The conception rate

on cattle with only liquid supplement was 8 to 19 lower than on

the other three treatments Economically the liquid supplement

was half the cost or less of the concentrate excluding labor

From this sfandpoint alone a rancher may be wIlling to accept

a slightly lower conception rate to obtain the decreased labor

and supplement cost Each individual rancher must measure cost

versus production

EFFECT OF OAK TREE REMOVAL ON FORAGE PRODUCTION

1981 was the sixteenth year that forage production has been measured in this study I have considered terminating the measurements because yield increases have not been significant in three of the last four years (see table) However data show that increases were significant in all of the sixteen years in which forage production on the check treatment (area covered by live trees) was below the median of the period (1385 Ibacre) Therefore in the interest of economy only the check treatments will be sampled in high rainfall years If another poor feed year occurs soon we will measure all treatments

6 Progress Report (Progress uring report perio toward reaching objectives of this research) The Ecologv and Population Dynamics of Aphodius fimetarius

The ecological study of the dung beetle Aphodius fimetarius was continued by again monitoring the ability of males and females to hibshyernate (aestivate) from late Spring to Fall From May 29 through June 9 we collected and marked 3020 beetles with fluorescent dust Half of these were released into a beetle-proof screened field cage in the Scott 14 pasture and the other half were released into a s~milar cage at the Howarth pasture o Both cages enclosed about 30 ft of natural turf and each was supplied with fresh dung (beetle food) until no beetles were present These two cages were monitored for the re-eppearance of beetles from September through December and cattle droppings from various pastures were sampled for the presence of naturally appearing wild beetles

During the past year the first beetles appeared in pasture droppings on November 4 when the dung peds had an average of 27 beetlespad On different weeks from November 11 through December 11 the density of ~ fimetarius remained fairly stable at 29 21 23 end 25 beetlespad As in previous years the beetle density then began to decline with 15pad on December 15 and less than one per pad on January 7 1982 In the Fall of 1981 beetles that had been marked and released into the experimental cages first appeared in the Scott 14 pasture on November 9 5 days after beetles first appeared in cattle dung pads in pastures The marked beetles contshyinued to appear in the Scott 14 cage through December with one beetle last appearing on December 16 No beetles were recovered in the Howarth pasture cage and through December 16 only 1 of marked beetles had been recovered in the Scott 14 cage This is in marked contrast to the cage recapture rates of 57 in the Scott pasture and 104 in the Howarth pasture It appears that beetles marked with the fluorescent dust suffershyed heavy mortality most of the marked beetles recovered had only a few particles of dust under the elytra or under the membraneous wings Nevertheless recapture of marked beetles confirmed that ~ fimetarius naturally hibernates (aestivates) in the ground for about 5 months in this part of California Other methods of marking beetles will be tested during the next seaSon

6 Progress Report (Progress during report period toward reaching objectives of thi 5 research)

The objectives of this research were outlined in the 1980 report Many of the same trends observed in 1980 were repeated in 1981 Body weights of the cows were positively related to level of supplementation

(Table 1) The greatest effect was observed at the start of the breeding season where the difference between the unsupplemented and 25 times supplemented cows was nearly 100 kg

Table 1 Body weight of cows (kg)

Weaning weight of the calves (Table 2) reflected the plane of nutrition of the cows Although weaning weights were enhanced by supplementation the largest differences in body weights occurred at the times the dams were mated Body weights of the calves reflected differential milk production of the cows

As in the previous year birth weight of the calves was not affected by plane of nutrition of the cows

6 Progress Report (Progress during report period toward reaching objectives of this research)

The major objectives of this research with Hereford cattle are (1) to determine if individual differences in mounting frequency by juvenile males correlate with individual differences in sexual motivation and performance as adults (2) to determine the degree of correlation between sexual behaviors and other biological traits (eg aggressive behavior semen characteristics hormone levels body size scrotal circumference) (3) to determine the function of mounting exshyperience on the development of sexual behavior and (4) to determine the role of penile stimulation on the development of sexual behavior

Over the last 4 years 78 bulls have been obtained from the SFRFS herd to investigate these questions Twenty-four male calves were brought to Davis from SFRFS in May 1981 to be used in studying objective 114 No observations were made on this group at the Field Station

Prior to 1981 all of our observations on juvenile mounting (Objectives 1 and 3) were made in confined situations where estrous heifers were provided as mountingstimuli and inter-animal contacts were frequent To determine the frequency of juvenile mounting in a more typical range environment 10 male and 9 female purebredHereford calves were observed between January 13 and March 22 1981 for a total of 40 hrs (29 different days) The calves ranged in age from 48 to 102 days (x = 80 days) at the start of observation A total of 394 calf observation hours were made on the 10 bull calves in the group and 749 calf hours on all 19 calves

Relative to our studies in confinement the rate of juvenile mounting in a typical range environment is very low A total of 15 mount intentions 12 mount attempts and 6 mounts (33 mount responses) were observed during the 40 hrs of observation Except for one mount intention all of the mounting activities were exhibited by bull calves The rate of mount responses was 0084 per bull calf per hour of observation Nearly all of the mounting behaviors were observed near the feed trough following feeding of supplements Supplemental feeding was terminated on February 25th and no sexual activity was observed among calves after that date

It was concluded that the mounting experience of 2-12 to 4-12 mo juvenilecalves in a ranqe environment is very limited

CO1tinued work in the Tea Garden Plot fairly well protected from deer has show~ reasonably good resul ts for only a few coni fer~ ad hardwoods The 100St

promising at present arc Monterey pine coast redwood and varieties of Pinus halepensis (brutia and eldarica) The most promising hardwoods to date are Eucalyptus globulus camaldulensis (2 variants) urnigera and grandis

In the lower Plot near the Yuba River deer and cattle damage al1d some porcupine debarking have greatly reduced the choice of species here The above pines Arizona cypress plus possibly tamarisk aphylla and coast redwood still appear promising

The North Plot after 3 years of trial plantings versus 4 for the other plots shows promising results for only Arizona cypress Eucalyptus grandis from 2 sources and tamarisk aphylla It is too early to rate the remainj~g species over-all survival rates of which are generally low

No fertilizer tablets have been applied to any of these plots because other factors limiting growth and survival appear more Important There was no serious rodent or insect damage noted in any of the 3 plots this past year and irrigation practices have been generally good probably supplying around 3 acre feet per growing season of about 6 months

It is now planned to establish semi-commercial plots of a minimum of 112 acre for each of at least 5 of the most promising species in another area of the Sierra Field Station

Development work continued in the Campbell Field A fall-1980 seeding of a perennia grass-legume pasture mixture on the new irrigated pasture areas was successful except for parts of some fields where irrigation water (surface flow) failed to reach In general the newly-installed irrigation system performed well

The following work was done on or related to the range fertilization study being conducted on the Forbes Flll44 series fields

a Soil samples were taken from each of the 16 fields Analyses will be made for P 5 Ca Mg K and pH

b In cooperation with M B Jones (HFS) field plots were established at eight locations (4 north-facing aspects 4 south-facing) A factorial design was used to compare 4 levels of N (as urea) and 4 levels of P (as low-S concentrated superphosphate) plus an exploratory for several combinations of NPS with two replications at each locati r

c Also in cooperation with M B Jones a greenhouse pot test was set up at the Hopland Field station with rate-element combinations to match those in the field plots using soil collected at the field locations for the eight replications The pots were seeded with a mixture of sub and rose clovers together with soft chess

d M R George and W J Clawson located sites for a grazing utilization study employing 10 x 10 exclosures

e A field-scale experiment with aerial application of nitrogen (as urea) at 0 40 80 and 120 kgha rates (two fields per replication two replications per treatment) is planned for fall 1982 following evaluation of the tests described above and results of a pre-experiment calibration grazing (with steers) beginning February 1982 Roy Hull J G Morris and R E Delmas are cooperators from the Department of Animal Science

6 Progress Report (Progress during report period toward reaching objectives of this research)

Four pairs of 14 acre plots were established during the fall of 1979 The Blue Oak overstory of these paired plots was approximately 0 25 50 and 75 The tree overstory was removed from one set of four plots by February 15 1980 and 12 wire mesh igloo type cages were placed on all plots by December 1980 Cages were located under tree canopy (or former tree canopy) and in the open using a stratified random procedure with proportional allocation

During 1981 three successive clippings were taken from inside the wire cages to determine the total standing crop present on February 21 (early season) April 3 amp 4 (mid-season) and June 2 (late season)

Preliminary Results (1981)

Uncleared plots 25 50 and 75 overstory cover Standing crop at any season did not differ appreciably by overstory level (Fig 1) When compared with uncleared open (0 overstory cover) plots standing crop was significantly less in uncleared plots at late season but not at early and mid-season Overstory cover and standing crop are not significantly correlated for any season (Fig 2)

Cleared Plots 25 50 and 75 prior overstory cover Standing crop is positively correlated with prior overstory cover particularly when uncleared open (0 overstory cover) plots are included in the comparison (Fig 2)

Tree removal greatly increased standing crop at all three seasons of harvest for all overstory cover levels (Fig 1) When compared to uncleared plots of the same overstory cover level these increases were 100 early season 133 midshyseason and 80 late season

6 Progress Report (Progress during report period toward reaching objectives of this research)

This experiment was undertaken to assess the efficacy and safety of a salt selenium mixture for supplementing range cows

Approximately a years data have been obtained on two groups each of 19 mature Hereford cows grazing range and offered two salt-selenium mineral mixtures free choice The concentration of selenium in one mixture was 40 ppm (low Se group) and the other 80 ppm (high Se group) These levels represent 2 and 4 times the maximal level currently permitted by FDA

Blood selenium concentrations (Figure 1) were determined on each animal at weekly intervals initially then at monthy intervals Intake of the salt-selenium mixture was also measured at monthly intervals to obtain total group mean intake of selenium

Blood selenium concentration rose from the initial concentration of 0035 ~gml to a maxima of approximately 0225 ~gm1 in the high group and 0150 ~gm1 in the low group at about 12 weeks Then maximal concentrations are within the range of normality and in no way indicate selenium toxicity

Intake of the salt-selenium mixture was not well correlated with blood concentration of se1eniUffl

Then data indicate that the FDA maximal level of 20 ppm selenium in salt supplements is conservative and may be ineffectual in areas of selenium deficiency There was no significant difference in the weight of the cows at the time the calves were weaned - low group 487 ~ 48 kg high group - 481 ~ 57 kg

SlJotMARY OF COMMENTS

The foothills of California offer an ideal place for people

to pursue farming Farming in the tradi tional sense family cerltered

labor interlsive small machinery oriented conservation minded small

Hopefully the U C Sierra Foothill Range Field Station will accept

and meet the challenge of providing research and information appropriate

to the fledgling development of a foothill agriculture ethic in which

the quality of food and living is paramount Projects of this nature

are few in the 1981 annual report Possibly we can make II greeter

contribution to foothill farming in the future

The breeding program utilizing polled Hereford sires AI continues A polled Hereford bull from a production tested herd was obtained an performance data from the purebred cow ~erdmiddotcontinues Test data of weaner bull calves with the best calves selected for use in the Sierra herds also continues

Weaning weight of calves from the cow herds was lower by 40-50 1bs due to a very rough 1980-81 winter Range clearing continues along with increased use of the heifers reared at Sierra as replacements in the cow herds Studies utilizing the progeny of the Sierra cow herds continue at Davis These progeny were transshyferred to trials for the Animal Science Faculty as well as utilized for teachshying In addition other units of the University have use of progeny of the Sierra herds such as Veterinary Medicine Cooperative Extension Entomology etc

An experiment is being conducted to determine the feasibility of producing twin calves under range conditions This research is a continuation of similar research carried out on the UCD campus and is designed to study the production of twins under practical range conditions Beef females of low and high milk producing abilityHerefords and Hereford x Holstein crossbreds respectively were induced to producetwins by embryo transfer Dams are being maintained throughout pregnancy and lactation on irrigated pasture Birth and weaning weights of single and twin calves as well as complications such as calf mortality retained placentas dystocia are being recorded

Evaluation of Ectiban Formulations For Fly Control on Cattle U C Sierra Foothill Range Field Station California 1981

E C Loomis PhD Parasitologist Lorry L Dunning Staff Research Associate

Extension Veterinary Medicine University of California Davis 95616

INTRODUCTION

Sixty (60)- Hereford heifers (avg wt4Q0 lbs) maintained on irrigated pasture at the U C Field Station were used for a fly control trial using Ectiban Pour~On and~Ectiban insecticide Ear Tag Tapes The heifers were divided into 6 equal groups of 10 each and were identified as groups 1 to 6 Twenty-five heifers of similar age and weight were kept on dry rangeland about 12 mile distant and served as Group 7 for a control (untreated) All 85 heifers were rated for horn fly densities in corrals prior to group separation and treatment but face fly counts were made in the field one week later

MATERIALS AND PROCEDURES

Ectiban formulations for trial evaluation consisted of a ready-to-use 1 Permethrin Pour-On (GFU003 Red 6766 dated 32481) and I-gram active ingredient Permethrin Ear Tag tapes for application to cattle ear tags These formulations were compared to a standard registered 005 spray using Coopertox Extra (Toxaphene 45 Lindane 196gt

Ectiban Pour-On was applied by means of 4 oz capacity metal dippers to 4 groups at a dosage of 12 ozcwt initially on June 10 and retreated on August 3 Groups 1 and 4 received a backline application while groups 2 and 5 received a face and poll application Groups 3 and 6 were sprayed over the entire body on June 10 and only Group 6 W4S resprayed on September 30 using 12 gallon (70 ozgt of Coopertox solution per head from a U C power sprayer equipped with a 6 HP Briggs amp Stratton engine plus by-pass pump system operated at 300 psi

Ectiban Ear Tag tapes for ear tag application arrived midway through the trial and some of the groups were split for tape application when retreatment was indicated on September 2 Groups 2 and 3 received one tape per heifer attached around the neck of the ear tag and Group I had a tape wrapped around the _end of the tail (above the switch) and secured with adhesive duct tape Groups 4 to 6 were not retreated at this time in order to determine possible effects of fly control from Ectiban-taped heifers which shared common fence lines and

2

exposure with the 3 Groups Following observations on September 23 it was decided to retreat Groups 4 to 6 on September 30 using the same Pour-On and Spray regimen as applied at the start of the trial

Visual fly counts by eye or with the aid of 7 x 50 binoculars were made in most cases by one observer on all 10 heifers in each of 6 Groups and on 10 of the 25 heifers in control Group 7 Counts were made from lOAM to 2PM at weekly intervals Horn fly counts (H irritans) were made on flies resting on one side of the body (withers ribcage and upper legs) and on Face flies (M autumnalis) resting on the face and head area

O~e way analysis of variance was used to determine if overall trea-tment means varied significantly Fishers LSD method was used to compare where differences occurred between treatment means

RESULTS AND DISCUSSION

The results on Horn fly control are shown in Table 1 Excellent control was obtained for 4 weeks (June 10 to July 7) for Ectiban backline Pour-On to Groups 1 and 4 while excellent to good control resulted from Ectiban face Pour-on on Groups 2 and 5 for the same 4 weeks Coopertox spray on Groups 3 and 6 provided excellent control for only 2 weeks (June 10 to 24) Surprisingly retreatment of the 4 Ectiban groups on August 2 provided not more than 2 weeks of satisfactory control Of equal interest was the dramatic decrease in horn flies for two weeks on Group 3 but only slightly so on Group 6 both of which were intentionally not resprayed with Coopertox on August 2 There was no significant difference between Ectiban Pour-On to the backline or to the face nor between these treatments and the Coopertox body spray as determined from mean totals on Horn fly populations for the entire trial period June 10 to October 17 all three treatments reduced horn flies significantly better (P lt 0005) than the control (Table 3)

Also included in Table 1 are the results for horn fly control following Ectiban Tape applications on September 2 Excellent control resulted for 4 weeks on taped-heifers in Groups 1 2 and 3 No significant difference occurred between tape treatments to the ear or tail but all 3 treatment groups showed significant fly reduction (P lt 0005) when compared to the control group (Table 4) Fly populations in control Group 7 decreased rapidly with the onset of cold nights during the week of October 10

The results on Face fly control are shown in Table 2 Relatively good control of this species occurred with the Pour-On treatments for about 2 weeks (June 10 to 24) -with almost similar results for the Coopertox spray Fly control on these same groups retreated on August 3 provided a shorter

period of control about 9 to 1i days the natural dccro(1s(~ in Face fly popula tion s dur i ng Ju 1 and Augus t as ev idenct~d in Control Group 7 is commonplace and fly numbers are too low to warrant reliable comparison witn treated animals There was no significant difference between the Ectiban Pour-On to the face or to the backlinebut both treatments -were significantly different (P lt 0005) than the Coopertox spray and the control (Table 3)

Also included in Table 2 are the results for Face fly control following Ectiban tape applications on September 2 Excellent (Group 2) to good (Group 3) control resulted one day after application with tapes applied to ear tags but control did not persist at a satisfactory level as evidenced by the increase in fly counts on September 9 there was poor control via tapes attached to the tail (Group 1) The poor significance of these results are shown in Table 4 Poor results were obtained on face fly ~ontrol upon retreatment of Groups 41 and 50n September 30 and similar JesuIts were evident on Group 6 which was resprayed wi th Co_opertlt~

Of interest in this trial were the results on Horn fly control from the small amount of Ectiban Pour-On to the face of animals Heretofore it was believed that a similar dose of a pesticide to the withers was more effective but if Face fly populations are the main target then face and head applications could serve a dual purpose to include Horn fly control

Early IrrIgation - Liquid Supplement Trial

RIck Delmas

This study was initiated In 1980 to study the performance of

cattle using liquid supplement and the effect of early irrigation of

annual grasslands for early fall growth on the performance of cattle

during the fall and winter grazing period

Though the trial needs to be continued for the next couple of

years the following are indicated from one years data

1) Early irrigation furnishes valuable early fall feed especially

in poor rainfall years

2) Liquid supplement doesnt appear to be as beneficial as concentrates

for young cattle during the fall and winter The conception rate

on cattle with only liquid supplement was 8 to 19 lower than on

the other three treatments Economically the liquid supplement

was half the cost or less of the concentrate excluding labor

From this sfandpoint alone a rancher may be wIlling to accept

a slightly lower conception rate to obtain the decreased labor

and supplement cost Each individual rancher must measure cost

versus production

EFFECT OF OAK TREE REMOVAL ON FORAGE PRODUCTION

1981 was the sixteenth year that forage production has been measured in this study I have considered terminating the measurements because yield increases have not been significant in three of the last four years (see table) However data show that increases were significant in all of the sixteen years in which forage production on the check treatment (area covered by live trees) was below the median of the period (1385 Ibacre) Therefore in the interest of economy only the check treatments will be sampled in high rainfall years If another poor feed year occurs soon we will measure all treatments

6 Progress Report (Progress uring report perio toward reaching objectives of this research) The Ecologv and Population Dynamics of Aphodius fimetarius

The ecological study of the dung beetle Aphodius fimetarius was continued by again monitoring the ability of males and females to hibshyernate (aestivate) from late Spring to Fall From May 29 through June 9 we collected and marked 3020 beetles with fluorescent dust Half of these were released into a beetle-proof screened field cage in the Scott 14 pasture and the other half were released into a s~milar cage at the Howarth pasture o Both cages enclosed about 30 ft of natural turf and each was supplied with fresh dung (beetle food) until no beetles were present These two cages were monitored for the re-eppearance of beetles from September through December and cattle droppings from various pastures were sampled for the presence of naturally appearing wild beetles

During the past year the first beetles appeared in pasture droppings on November 4 when the dung peds had an average of 27 beetlespad On different weeks from November 11 through December 11 the density of ~ fimetarius remained fairly stable at 29 21 23 end 25 beetlespad As in previous years the beetle density then began to decline with 15pad on December 15 and less than one per pad on January 7 1982 In the Fall of 1981 beetles that had been marked and released into the experimental cages first appeared in the Scott 14 pasture on November 9 5 days after beetles first appeared in cattle dung pads in pastures The marked beetles contshyinued to appear in the Scott 14 cage through December with one beetle last appearing on December 16 No beetles were recovered in the Howarth pasture cage and through December 16 only 1 of marked beetles had been recovered in the Scott 14 cage This is in marked contrast to the cage recapture rates of 57 in the Scott pasture and 104 in the Howarth pasture It appears that beetles marked with the fluorescent dust suffershyed heavy mortality most of the marked beetles recovered had only a few particles of dust under the elytra or under the membraneous wings Nevertheless recapture of marked beetles confirmed that ~ fimetarius naturally hibernates (aestivates) in the ground for about 5 months in this part of California Other methods of marking beetles will be tested during the next seaSon

The objectives of this research were outlined in the 1980 report Many of the same trends observed in 1980 were repeated in 1981 Body weights of the cows were positively related to level of supplementation

(Table 1) The greatest effect was observed at the start of the breeding season where the difference between the unsupplemented and 25 times supplemented cows was nearly 100 kg

Weaning weight of the calves (Table 2) reflected the plane of nutrition of the cows Although weaning weights were enhanced by supplementation the largest differences in body weights occurred at the times the dams were mated Body weights of the calves reflected differential milk production of the cows

As in the previous year birth weight of the calves was not affected by plane of nutrition of the cows

6 Progress Report (Progress during report period toward reaching objectives of this research)

The major objectives of this research with Hereford cattle are (1) to determine if individual differences in mounting frequency by juvenile males correlate with individual differences in sexual motivation and performance as adults (2) to determine the degree of correlation between sexual behaviors and other biological traits (eg aggressive behavior semen characteristics hormone levels body size scrotal circumference) (3) to determine the function of mounting exshyperience on the development of sexual behavior and (4) to determine the role of penile stimulation on the development of sexual behavior

Over the last 4 years 78 bulls have been obtained from the SFRFS herd to investigate these questions Twenty-four male calves were brought to Davis from SFRFS in May 1981 to be used in studying objective 114 No observations were made on this group at the Field Station

Prior to 1981 all of our observations on juvenile mounting (Objectives 1 and 3) were made in confined situations where estrous heifers were provided as mountingstimuli and inter-animal contacts were frequent To determine the frequency of juvenile mounting in a more typical range environment 10 male and 9 female purebredHereford calves were observed between January 13 and March 22 1981 for a total of 40 hrs (29 different days) The calves ranged in age from 48 to 102 days (x = 80 days) at the start of observation A total of 394 calf observation hours were made on the 10 bull calves in the group and 749 calf hours on all 19 calves

Relative to our studies in confinement the rate of juvenile mounting in a typical range environment is very low A total of 15 mount intentions 12 mount attempts and 6 mounts (33 mount responses) were observed during the 40 hrs of observation Except for one mount intention all of the mounting activities were exhibited by bull calves The rate of mount responses was 0084 per bull calf per hour of observation Nearly all of the mounting behaviors were observed near the feed trough following feeding of supplements Supplemental feeding was terminated on February 25th and no sexual activity was observed among calves after that date

It was concluded that the mounting experience of 2-12 to 4-12 mo juvenilecalves in a ranqe environment is very limited

promising at present arc Monterey pine coast redwood and varieties of Pinus halepensis (brutia and eldarica) The most promising hardwoods to date are Eucalyptus globulus camaldulensis (2 variants) urnigera and grandis

In the lower Plot near the Yuba River deer and cattle damage al1d some porcupine debarking have greatly reduced the choice of species here The above pines Arizona cypress plus possibly tamarisk aphylla and coast redwood still appear promising

The North Plot after 3 years of trial plantings versus 4 for the other plots shows promising results for only Arizona cypress Eucalyptus grandis from 2 sources and tamarisk aphylla It is too early to rate the remainj~g species over-all survival rates of which are generally low

No fertilizer tablets have been applied to any of these plots because other factors limiting growth and survival appear more Important There was no serious rodent or insect damage noted in any of the 3 plots this past year and irrigation practices have been generally good probably supplying around 3 acre feet per growing season of about 6 months

It is now planned to establish semi-commercial plots of a minimum of 112 acre for each of at least 5 of the most promising species in another area of the Sierra Field Station

Development work continued in the Campbell Field A fall-1980 seeding of a perennia grass-legume pasture mixture on the new irrigated pasture areas was successful except for parts of some fields where irrigation water (surface flow) failed to reach In general the newly-installed irrigation system performed well

The following work was done on or related to the range fertilization study being conducted on the Forbes Flll44 series fields

a Soil samples were taken from each of the 16 fields Analyses will be made for P 5 Ca Mg K and pH

b In cooperation with M B Jones (HFS) field plots were established at eight locations (4 north-facing aspects 4 south-facing) A factorial design was used to compare 4 levels of N (as urea) and 4 levels of P (as low-S concentrated superphosphate) plus an exploratory for several combinations of NPS with two replications at each locati r

c Also in cooperation with M B Jones a greenhouse pot test was set up at the Hopland Field station with rate-element combinations to match those in the field plots using soil collected at the field locations for the eight replications The pots were seeded with a mixture of sub and rose clovers together with soft chess

d M R George and W J Clawson located sites for a grazing utilization study employing 10 x 10 exclosures

6 Progress Report (Progress during report period toward reaching objectives of this research)

Four pairs of 14 acre plots were established during the fall of 1979 The Blue Oak overstory of these paired plots was approximately 0 25 50 and 75 The tree overstory was removed from one set of four plots by February 15 1980 and 12 wire mesh igloo type cages were placed on all plots by December 1980 Cages were located under tree canopy (or former tree canopy) and in the open using a stratified random procedure with proportional allocation

During 1981 three successive clippings were taken from inside the wire cages to determine the total standing crop present on February 21 (early season) April 3 amp 4 (mid-season) and June 2 (late season)

Preliminary Results (1981)

Uncleared plots 25 50 and 75 overstory cover Standing crop at any season did not differ appreciably by overstory level (Fig 1) When compared with uncleared open (0 overstory cover) plots standing crop was significantly less in uncleared plots at late season but not at early and mid-season Overstory cover and standing crop are not significantly correlated for any season (Fig 2)

Cleared Plots 25 50 and 75 prior overstory cover Standing crop is positively correlated with prior overstory cover particularly when uncleared open (0 overstory cover) plots are included in the comparison (Fig 2)

Tree removal greatly increased standing crop at all three seasons of harvest for all overstory cover levels (Fig 1) When compared to uncleared plots of the same overstory cover level these increases were 100 early season 133 midshyseason and 80 late season

this research)

During the first phase of the trial we are observing tropical plants Varieties were I isted in last year1s report The Leucaena species was eliminated Last winter was a relatively mild winter thus we feel we did not obtain good cold readings on the other species Further observations will be made this coming year

In the second phase we have planted species and varieties of Orchardgrass Tall Fescue and Perennial Ryegrass from the Georgia Plant Station In addition planted species of the same plants used in California irrigated pastures Stand evaluations were made on all species this past year only This coming year we will obtain yield data

The major objective of this study is to determine differences in the maternal care provided tw1n calves relative to the maternal behavior of cows with singleoffspring when placed 1n a range environment Observations were conducted duringJanuary February and March 1981 at SFRFS on 7 cows with single calves and 5 cows with twins housed in a 75A pasture The animals were observed for 15 hrs per week during the f1rst two hrs following sunrise and the two hrs preceding sunset

Data collected on mothers included frequency and duration of licking (grooming) calves vocalizattons butts and butt attempts directed at alien calves and behavioral responses to separatton from calf(ves) Calves were observed for frequency and duration of sucking on own and aUen mothers frequency and duration of resting runn1ng laying and grazing frequency of vocalizations and juvenilemounting and prox1m1ty to mother tw1n and nea~est unrelated calf

The data have been compiled but have not yet been analyzed statistically

Efficacy of sall as a vehicle for selenium supplementatio~

4 Project Leader J G Morri 5 1 5 bull Period Covered QL sectL - 1L A by this Report mo yr mo yr

6 Progress Report (Progress during report period toward reaching objectives of this research)

This experiment was undertaken to assess the efficacy and safety of a salt selenium mixture for supplementing range cows

Approximately a years data have been obtained on two groups each of 19 mature Hereford cows grazing range and offered two salt-selenium mineral mixtures free choice The concentration of selenium in one mixture was 40 ppm (low Se group) and the other 80 ppm (high Se group) These levels represent 2 and 4 times the maximal level currently permitted by FDA

Blood selenium concentrations (Figure 1) were determined on each animal at weekly intervals initially then at monthy intervals Intake of the salt-selenium mixture was also measured at monthly intervals to obtain total group mean intake of selenium

Blood selenium concentration rose from the initial concentration of 0035 ~gml to a maxima of approximately 0225 ~gm1 in the high group and 0150 ~gm1 in the low group at about 12 weeks Then maximal concentrations are within the range of normality and in no way indicate selenium toxicity

Intake of the salt-selenium mixture was not well correlated with blood concentration of se1eniUffl

Then data indicate that the FDA maximal level of 20 ppm selenium in salt supplements is conservative and may be ineffectual in areas of selenium deficiency There was no significant difference in the weight of the cows at the time the calves were weaned - low group 487 ~ 48 kg high group - 481 ~ 57 kg

SlJotMARY OF COMMENTS

The foothills of California offer an ideal place for people

to pursue farming Farming in the tradi tional sense family cerltered

labor interlsive small machinery oriented conservation minded small

Hopefully the U C Sierra Foothill Range Field Station will accept

and meet the challenge of providing research and information appropriate

to the fledgling development of a foothill agriculture ethic in which

the quality of food and living is paramount Projects of this nature

are few in the 1981 annual report Possibly we can make II greeter

contribution to foothill farming in the future

Evaluation of Ectiban Formulations For Fly Control on Cattle U C Sierra Foothill Range Field Station California 1981

E C Loomis PhD Parasitologist Lorry L Dunning Staff Research Associate

Extension Veterinary Medicine University of California Davis 95616

INTRODUCTION

Sixty (60)- Hereford heifers (avg wt4Q0 lbs) maintained on irrigated pasture at the U C Field Station were used for a fly control trial using Ectiban Pour~On and~Ectiban insecticide Ear Tag Tapes The heifers were divided into 6 equal groups of 10 each and were identified as groups 1 to 6 Twenty-five heifers of similar age and weight were kept on dry rangeland about 12 mile distant and served as Group 7 for a control (untreated) All 85 heifers were rated for horn fly densities in corrals prior to group separation and treatment but face fly counts were made in the field one week later

MATERIALS AND PROCEDURES

Ectiban formulations for trial evaluation consisted of a ready-to-use 1 Permethrin Pour-On (GFU003 Red 6766 dated 32481) and I-gram active ingredient Permethrin Ear Tag tapes for application to cattle ear tags These formulations were compared to a standard registered 005 spray using Coopertox Extra (Toxaphene 45 Lindane 196gt

Ectiban Pour-On was applied by means of 4 oz capacity metal dippers to 4 groups at a dosage of 12 ozcwt initially on June 10 and retreated on August 3 Groups 1 and 4 received a backline application while groups 2 and 5 received a face and poll application Groups 3 and 6 were sprayed over the entire body on June 10 and only Group 6 W4S resprayed on September 30 using 12 gallon (70 ozgt of Coopertox solution per head from a U C power sprayer equipped with a 6 HP Briggs amp Stratton engine plus by-pass pump system operated at 300 psi

Ectiban Ear Tag tapes for ear tag application arrived midway through the trial and some of the groups were split for tape application when retreatment was indicated on September 2 Groups 2 and 3 received one tape per heifer attached around the neck of the ear tag and Group I had a tape wrapped around the _end of the tail (above the switch) and secured with adhesive duct tape Groups 4 to 6 were not retreated at this time in order to determine possible effects of fly control from Ectiban-taped heifers which shared common fence lines and

2

exposure with the 3 Groups Following observations on September 23 it was decided to retreat Groups 4 to 6 on September 30 using the same Pour-On and Spray regimen as applied at the start of the trial

Visual fly counts by eye or with the aid of 7 x 50 binoculars were made in most cases by one observer on all 10 heifers in each of 6 Groups and on 10 of the 25 heifers in control Group 7 Counts were made from lOAM to 2PM at weekly intervals Horn fly counts (H irritans) were made on flies resting on one side of the body (withers ribcage and upper legs) and on Face flies (M autumnalis) resting on the face and head area

O~e way analysis of variance was used to determine if overall trea-tment means varied significantly Fishers LSD method was used to compare where differences occurred between treatment means

RESULTS AND DISCUSSION

The results on Horn fly control are shown in Table 1 Excellent control was obtained for 4 weeks (June 10 to July 7) for Ectiban backline Pour-On to Groups 1 and 4 while excellent to good control resulted from Ectiban face Pour-on on Groups 2 and 5 for the same 4 weeks Coopertox spray on Groups 3 and 6 provided excellent control for only 2 weeks (June 10 to 24) Surprisingly retreatment of the 4 Ectiban groups on August 2 provided not more than 2 weeks of satisfactory control Of equal interest was the dramatic decrease in horn flies for two weeks on Group 3 but only slightly so on Group 6 both of which were intentionally not resprayed with Coopertox on August 2 There was no significant difference between Ectiban Pour-On to the backline or to the face nor between these treatments and the Coopertox body spray as determined from mean totals on Horn fly populations for the entire trial period June 10 to October 17 all three treatments reduced horn flies significantly better (P lt 0005) than the control (Table 3)

Also included in Table 1 are the results for horn fly control following Ectiban Tape applications on September 2 Excellent control resulted for 4 weeks on taped-heifers in Groups 1 2 and 3 No significant difference occurred between tape treatments to the ear or tail but all 3 treatment groups showed significant fly reduction (P lt 0005) when compared to the control group (Table 4) Fly populations in control Group 7 decreased rapidly with the onset of cold nights during the week of October 10

The results on Face fly control are shown in Table 2 Relatively good control of this species occurred with the Pour-On treatments for about 2 weeks (June 10 to 24) -with almost similar results for the Coopertox spray Fly control on these same groups retreated on August 3 provided a shorter

period of control about 9 to 1i days the natural dccro(1s(~ in Face fly popula tion s dur i ng Ju 1 and Augus t as ev idenct~d in Control Group 7 is commonplace and fly numbers are too low to warrant reliable comparison witn treated animals There was no significant difference between the Ectiban Pour-On to the face or to the backlinebut both treatments -were significantly different (P lt 0005) than the Coopertox spray and the control (Table 3)

Also included in Table 2 are the results for Face fly control following Ectiban tape applications on September 2 Excellent (Group 2) to good (Group 3) control resulted one day after application with tapes applied to ear tags but control did not persist at a satisfactory level as evidenced by the increase in fly counts on September 9 there was poor control via tapes attached to the tail (Group 1) The poor significance of these results are shown in Table 4 Poor results were obtained on face fly ~ontrol upon retreatment of Groups 41 and 50n September 30 and similar JesuIts were evident on Group 6 which was resprayed wi th Co_opertlt~

Of interest in this trial were the results on Horn fly control from the small amount of Ectiban Pour-On to the face of animals Heretofore it was believed that a similar dose of a pesticide to the withers was more effective but if Face fly populations are the main target then face and head applications could serve a dual purpose to include Horn fly control

Early IrrIgation - Liquid Supplement Trial

RIck Delmas

This study was initiated In 1980 to study the performance of

cattle using liquid supplement and the effect of early irrigation of

annual grasslands for early fall growth on the performance of cattle

during the fall and winter grazing period

Though the trial needs to be continued for the next couple of

years the following are indicated from one years data

1) Early irrigation furnishes valuable early fall feed especially

in poor rainfall years

2) Liquid supplement doesnt appear to be as beneficial as concentrates

for young cattle during the fall and winter The conception rate

on cattle with only liquid supplement was 8 to 19 lower than on

the other three treatments Economically the liquid supplement

was half the cost or less of the concentrate excluding labor

From this sfandpoint alone a rancher may be wIlling to accept

a slightly lower conception rate to obtain the decreased labor

and supplement cost Each individual rancher must measure cost

versus production

EFFECT OF OAK TREE REMOVAL ON FORAGE PRODUCTION

1981 was the sixteenth year that forage production has been measured in this study I have considered terminating the measurements because yield increases have not been significant in three of the last four years (see table) However data show that increases were significant in all of the sixteen years in which forage production on the check treatment (area covered by live trees) was below the median of the period (1385 Ibacre) Therefore in the interest of economy only the check treatments will be sampled in high rainfall years If another poor feed year occurs soon we will measure all treatments

6 Progress Report (Progress uring report perio toward reaching objectives of this research) The Ecologv and Population Dynamics of Aphodius fimetarius

The ecological study of the dung beetle Aphodius fimetarius was continued by again monitoring the ability of males and females to hibshyernate (aestivate) from late Spring to Fall From May 29 through June 9 we collected and marked 3020 beetles with fluorescent dust Half of these were released into a beetle-proof screened field cage in the Scott 14 pasture and the other half were released into a s~milar cage at the Howarth pasture o Both cages enclosed about 30 ft of natural turf and each was supplied with fresh dung (beetle food) until no beetles were present These two cages were monitored for the re-eppearance of beetles from September through December and cattle droppings from various pastures were sampled for the presence of naturally appearing wild beetles

During the past year the first beetles appeared in pasture droppings on November 4 when the dung peds had an average of 27 beetlespad On different weeks from November 11 through December 11 the density of ~ fimetarius remained fairly stable at 29 21 23 end 25 beetlespad As in previous years the beetle density then began to decline with 15pad on December 15 and less than one per pad on January 7 1982 In the Fall of 1981 beetles that had been marked and released into the experimental cages first appeared in the Scott 14 pasture on November 9 5 days after beetles first appeared in cattle dung pads in pastures The marked beetles contshyinued to appear in the Scott 14 cage through December with one beetle last appearing on December 16 No beetles were recovered in the Howarth pasture cage and through December 16 only 1 of marked beetles had been recovered in the Scott 14 cage This is in marked contrast to the cage recapture rates of 57 in the Scott pasture and 104 in the Howarth pasture It appears that beetles marked with the fluorescent dust suffershyed heavy mortality most of the marked beetles recovered had only a few particles of dust under the elytra or under the membraneous wings Nevertheless recapture of marked beetles confirmed that ~ fimetarius naturally hibernates (aestivates) in the ground for about 5 months in this part of California Other methods of marking beetles will be tested during the next seaSon

The objectives of this research were outlined in the 1980 report Many of the same trends observed in 1980 were repeated in 1981 Body weights of the cows were positively related to level of supplementation

(Table 1) The greatest effect was observed at the start of the breeding season where the difference between the unsupplemented and 25 times supplemented cows was nearly 100 kg

Weaning weight of the calves (Table 2) reflected the plane of nutrition of the cows Although weaning weights were enhanced by supplementation the largest differences in body weights occurred at the times the dams were mated Body weights of the calves reflected differential milk production of the cows

As in the previous year birth weight of the calves was not affected by plane of nutrition of the cows

6 Progress Report (Progress during report period toward reaching objectives of this research)

The major objectives of this research with Hereford cattle are (1) to determine if individual differences in mounting frequency by juvenile males correlate with individual differences in sexual motivation and performance as adults (2) to determine the degree of correlation between sexual behaviors and other biological traits (eg aggressive behavior semen characteristics hormone levels body size scrotal circumference) (3) to determine the function of mounting exshyperience on the development of sexual behavior and (4) to determine the role of penile stimulation on the development of sexual behavior

Over the last 4 years 78 bulls have been obtained from the SFRFS herd to investigate these questions Twenty-four male calves were brought to Davis from SFRFS in May 1981 to be used in studying objective 114 No observations were made on this group at the Field Station

Prior to 1981 all of our observations on juvenile mounting (Objectives 1 and 3) were made in confined situations where estrous heifers were provided as mountingstimuli and inter-animal contacts were frequent To determine the frequency of juvenile mounting in a more typical range environment 10 male and 9 female purebredHereford calves were observed between January 13 and March 22 1981 for a total of 40 hrs (29 different days) The calves ranged in age from 48 to 102 days (x = 80 days) at the start of observation A total of 394 calf observation hours were made on the 10 bull calves in the group and 749 calf hours on all 19 calves

Relative to our studies in confinement the rate of juvenile mounting in a typical range environment is very low A total of 15 mount intentions 12 mount attempts and 6 mounts (33 mount responses) were observed during the 40 hrs of observation Except for one mount intention all of the mounting activities were exhibited by bull calves The rate of mount responses was 0084 per bull calf per hour of observation Nearly all of the mounting behaviors were observed near the feed trough following feeding of supplements Supplemental feeding was terminated on February 25th and no sexual activity was observed among calves after that date

It was concluded that the mounting experience of 2-12 to 4-12 mo juvenilecalves in a ranqe environment is very limited

promising at present arc Monterey pine coast redwood and varieties of Pinus halepensis (brutia and eldarica) The most promising hardwoods to date are Eucalyptus globulus camaldulensis (2 variants) urnigera and grandis

In the lower Plot near the Yuba River deer and cattle damage al1d some porcupine debarking have greatly reduced the choice of species here The above pines Arizona cypress plus possibly tamarisk aphylla and coast redwood still appear promising

The North Plot after 3 years of trial plantings versus 4 for the other plots shows promising results for only Arizona cypress Eucalyptus grandis from 2 sources and tamarisk aphylla It is too early to rate the remainj~g species over-all survival rates of which are generally low

No fertilizer tablets have been applied to any of these plots because other factors limiting growth and survival appear more Important There was no serious rodent or insect damage noted in any of the 3 plots this past year and irrigation practices have been generally good probably supplying around 3 acre feet per growing season of about 6 months

It is now planned to establish semi-commercial plots of a minimum of 112 acre for each of at least 5 of the most promising species in another area of the Sierra Field Station

Development work continued in the Campbell Field A fall-1980 seeding of a perennia grass-legume pasture mixture on the new irrigated pasture areas was successful except for parts of some fields where irrigation water (surface flow) failed to reach In general the newly-installed irrigation system performed well

The following work was done on or related to the range fertilization study being conducted on the Forbes Flll44 series fields

a Soil samples were taken from each of the 16 fields Analyses will be made for P 5 Ca Mg K and pH

b In cooperation with M B Jones (HFS) field plots were established at eight locations (4 north-facing aspects 4 south-facing) A factorial design was used to compare 4 levels of N (as urea) and 4 levels of P (as low-S concentrated superphosphate) plus an exploratory for several combinations of NPS with two replications at each locati r

c Also in cooperation with M B Jones a greenhouse pot test was set up at the Hopland Field station with rate-element combinations to match those in the field plots using soil collected at the field locations for the eight replications The pots were seeded with a mixture of sub and rose clovers together with soft chess

d M R George and W J Clawson located sites for a grazing utilization study employing 10 x 10 exclosures

e A field-scale experiment with aerial application of nitrogen (as urea) at 0 40 80 and 120 kgha rates (two fields per replication two replications per treatment) is planned for fall 1982 following evaluation of the tests described above and results of a pre-experiment calibration grazing (with steers) beginning February 1982 Roy Hull J G Morris and R E Delmas are cooperators from the Department of Animal Science

6 Progress Report (Progress during report period toward reaching objectives of this research)

Four pairs of 14 acre plots were established during the fall of 1979 The Blue Oak overstory of these paired plots was approximately 0 25 50 and 75 The tree overstory was removed from one set of four plots by February 15 1980 and 12 wire mesh igloo type cages were placed on all plots by December 1980 Cages were located under tree canopy (or former tree canopy) and in the open using a stratified random procedure with proportional allocation

During 1981 three successive clippings were taken from inside the wire cages to determine the total standing crop present on February 21 (early season) April 3 amp 4 (mid-season) and June 2 (late season)

Preliminary Results (1981)

Uncleared plots 25 50 and 75 overstory cover Standing crop at any season did not differ appreciably by overstory level (Fig 1) When compared with uncleared open (0 overstory cover) plots standing crop was significantly less in uncleared plots at late season but not at early and mid-season Overstory cover and standing crop are not significantly correlated for any season (Fig 2)

Cleared Plots 25 50 and 75 prior overstory cover Standing crop is positively correlated with prior overstory cover particularly when uncleared open (0 overstory cover) plots are included in the comparison (Fig 2)

Tree removal greatly increased standing crop at all three seasons of harvest for all overstory cover levels (Fig 1) When compared to uncleared plots of the same overstory cover level these increases were 100 early season 133 midshyseason and 80 late season

6 Progress Report (Progress during report period toward reaching objectives of this research)

This experiment was undertaken to assess the efficacy and safety of a salt selenium mixture for supplementing range cows

Approximately a years data have been obtained on two groups each of 19 mature Hereford cows grazing range and offered two salt-selenium mineral mixtures free choice The concentration of selenium in one mixture was 40 ppm (low Se group) and the other 80 ppm (high Se group) These levels represent 2 and 4 times the maximal level currently permitted by FDA

Blood selenium concentrations (Figure 1) were determined on each animal at weekly intervals initially then at monthy intervals Intake of the salt-selenium mixture was also measured at monthly intervals to obtain total group mean intake of selenium

Blood selenium concentration rose from the initial concentration of 0035 ~gml to a maxima of approximately 0225 ~gm1 in the high group and 0150 ~gm1 in the low group at about 12 weeks Then maximal concentrations are within the range of normality and in no way indicate selenium toxicity

Intake of the salt-selenium mixture was not well correlated with blood concentration of se1eniUffl

Then data indicate that the FDA maximal level of 20 ppm selenium in salt supplements is conservative and may be ineffectual in areas of selenium deficiency There was no significant difference in the weight of the cows at the time the calves were weaned - low group 487 ~ 48 kg high group - 481 ~ 57 kg

The foothills of California offer an ideal place for people

to pursue farming Farming in the tradi tional sense family cerltered

labor interlsive small machinery oriented conservation minded small

Hopefully the U C Sierra Foothill Range Field Station will accept

and meet the challenge of providing research and information appropriate

to the fledgling development of a foothill agriculture ethic in which

the quality of food and living is paramount Projects of this nature

are few in the 1981 annual report Possibly we can make II greeter

contribution to foothill farming in the future

The breeding program utilizing polled Hereford sires AI continues A polled Hereford bull from a production tested herd was obtained an performance data from the purebred cow ~erdmiddotcontinues Test data of weaner bull calves with the best calves selected for use in the Sierra herds also continues

Weaning weight of calves from the cow herds was lower by 40-50 1bs due to a very rough 1980-81 winter Range clearing continues along with increased use of the heifers reared at Sierra as replacements in the cow herds Studies utilizing the progeny of the Sierra cow herds continue at Davis These progeny were transshyferred to trials for the Animal Science Faculty as well as utilized for teachshying In addition other units of the University have use of progeny of the Sierra herds such as Veterinary Medicine Cooperative Extension Entomology etc

An experiment is being conducted to determine the feasibility of producing twin calves under range conditions This research is a continuation of similar research carried out on the UCD campus and is designed to study the production of twins under practical range conditions Beef females of low and high milk producing abilityHerefords and Hereford x Holstein crossbreds respectively were induced to producetwins by embryo transfer Dams are being maintained throughout pregnancy and lactation on irrigated pasture Birth and weaning weights of single and twin calves as well as complications such as calf mortality retained placentas dystocia are being recorded

Evaluation of Ectiban Formulations For Fly Control on Cattle U C Sierra Foothill Range Field Station California 1981

E C Loomis PhD Parasitologist Lorry L Dunning Staff Research Associate

Extension Veterinary Medicine University of California Davis 95616

INTRODUCTION

Sixty (60)- Hereford heifers (avg wt4Q0 lbs) maintained on irrigated pasture at the U C Field Station were used for a fly control trial using Ectiban Pour~On and~Ectiban insecticide Ear Tag Tapes The heifers were divided into 6 equal groups of 10 each and were identified as groups 1 to 6 Twenty-five heifers of similar age and weight were kept on dry rangeland about 12 mile distant and served as Group 7 for a control (untreated) All 85 heifers were rated for horn fly densities in corrals prior to group separation and treatment but face fly counts were made in the field one week later

MATERIALS AND PROCEDURES

Ectiban formulations for trial evaluation consisted of a ready-to-use 1 Permethrin Pour-On (GFU003 Red 6766 dated 32481) and I-gram active ingredient Permethrin Ear Tag tapes for application to cattle ear tags These formulations were compared to a standard registered 005 spray using Coopertox Extra (Toxaphene 45 Lindane 196gt

Ectiban Pour-On was applied by means of 4 oz capacity metal dippers to 4 groups at a dosage of 12 ozcwt initially on June 10 and retreated on August 3 Groups 1 and 4 received a backline application while groups 2 and 5 received a face and poll application Groups 3 and 6 were sprayed over the entire body on June 10 and only Group 6 W4S resprayed on September 30 using 12 gallon (70 ozgt of Coopertox solution per head from a U C power sprayer equipped with a 6 HP Briggs amp Stratton engine plus by-pass pump system operated at 300 psi

Ectiban Ear Tag tapes for ear tag application arrived midway through the trial and some of the groups were split for tape application when retreatment was indicated on September 2 Groups 2 and 3 received one tape per heifer attached around the neck of the ear tag and Group I had a tape wrapped around the _end of the tail (above the switch) and secured with adhesive duct tape Groups 4 to 6 were not retreated at this time in order to determine possible effects of fly control from Ectiban-taped heifers which shared common fence lines and

2

exposure with the 3 Groups Following observations on September 23 it was decided to retreat Groups 4 to 6 on September 30 using the same Pour-On and Spray regimen as applied at the start of the trial

Visual fly counts by eye or with the aid of 7 x 50 binoculars were made in most cases by one observer on all 10 heifers in each of 6 Groups and on 10 of the 25 heifers in control Group 7 Counts were made from lOAM to 2PM at weekly intervals Horn fly counts (H irritans) were made on flies resting on one side of the body (withers ribcage and upper legs) and on Face flies (M autumnalis) resting on the face and head area

O~e way analysis of variance was used to determine if overall trea-tment means varied significantly Fishers LSD method was used to compare where differences occurred between treatment means

RESULTS AND DISCUSSION

The results on Horn fly control are shown in Table 1 Excellent control was obtained for 4 weeks (June 10 to July 7) for Ectiban backline Pour-On to Groups 1 and 4 while excellent to good control resulted from Ectiban face Pour-on on Groups 2 and 5 for the same 4 weeks Coopertox spray on Groups 3 and 6 provided excellent control for only 2 weeks (June 10 to 24) Surprisingly retreatment of the 4 Ectiban groups on August 2 provided not more than 2 weeks of satisfactory control Of equal interest was the dramatic decrease in horn flies for two weeks on Group 3 but only slightly so on Group 6 both of which were intentionally not resprayed with Coopertox on August 2 There was no significant difference between Ectiban Pour-On to the backline or to the face nor between these treatments and the Coopertox body spray as determined from mean totals on Horn fly populations for the entire trial period June 10 to October 17 all three treatments reduced horn flies significantly better (P lt 0005) than the control (Table 3)

Also included in Table 1 are the results for horn fly control following Ectiban Tape applications on September 2 Excellent control resulted for 4 weeks on taped-heifers in Groups 1 2 and 3 No significant difference occurred between tape treatments to the ear or tail but all 3 treatment groups showed significant fly reduction (P lt 0005) when compared to the control group (Table 4) Fly populations in control Group 7 decreased rapidly with the onset of cold nights during the week of October 10

The results on Face fly control are shown in Table 2 Relatively good control of this species occurred with the Pour-On treatments for about 2 weeks (June 10 to 24) -with almost similar results for the Coopertox spray Fly control on these same groups retreated on August 3 provided a shorter

period of control about 9 to 1i days the natural dccro(1s(~ in Face fly popula tion s dur i ng Ju 1 and Augus t as ev idenct~d in Control Group 7 is commonplace and fly numbers are too low to warrant reliable comparison witn treated animals There was no significant difference between the Ectiban Pour-On to the face or to the backlinebut both treatments -were significantly different (P lt 0005) than the Coopertox spray and the control (Table 3)

Also included in Table 2 are the results for Face fly control following Ectiban tape applications on September 2 Excellent (Group 2) to good (Group 3) control resulted one day after application with tapes applied to ear tags but control did not persist at a satisfactory level as evidenced by the increase in fly counts on September 9 there was poor control via tapes attached to the tail (Group 1) The poor significance of these results are shown in Table 4 Poor results were obtained on face fly ~ontrol upon retreatment of Groups 41 and 50n September 30 and similar JesuIts were evident on Group 6 which was resprayed wi th Co_opertlt~

Of interest in this trial were the results on Horn fly control from the small amount of Ectiban Pour-On to the face of animals Heretofore it was believed that a similar dose of a pesticide to the withers was more effective but if Face fly populations are the main target then face and head applications could serve a dual purpose to include Horn fly control

Early IrrIgation - Liquid Supplement Trial

RIck Delmas

This study was initiated In 1980 to study the performance of

cattle using liquid supplement and the effect of early irrigation of

annual grasslands for early fall growth on the performance of cattle

during the fall and winter grazing period

Though the trial needs to be continued for the next couple of

years the following are indicated from one years data

1) Early irrigation furnishes valuable early fall feed especially

in poor rainfall years

2) Liquid supplement doesnt appear to be as beneficial as concentrates

for young cattle during the fall and winter The conception rate

on cattle with only liquid supplement was 8 to 19 lower than on

the other three treatments Economically the liquid supplement

was half the cost or less of the concentrate excluding labor

From this sfandpoint alone a rancher may be wIlling to accept

a slightly lower conception rate to obtain the decreased labor

and supplement cost Each individual rancher must measure cost

versus production

EFFECT OF OAK TREE REMOVAL ON FORAGE PRODUCTION

1981 was the sixteenth year that forage production has been measured in this study I have considered terminating the measurements because yield increases have not been significant in three of the last four years (see table) However data show that increases were significant in all of the sixteen years in which forage production on the check treatment (area covered by live trees) was below the median of the period (1385 Ibacre) Therefore in the interest of economy only the check treatments will be sampled in high rainfall years If another poor feed year occurs soon we will measure all treatments

6 Progress Report (Progress uring report perio toward reaching objectives of this research) The Ecologv and Population Dynamics of Aphodius fimetarius

The ecological study of the dung beetle Aphodius fimetarius was continued by again monitoring the ability of males and females to hibshyernate (aestivate) from late Spring to Fall From May 29 through June 9 we collected and marked 3020 beetles with fluorescent dust Half of these were released into a beetle-proof screened field cage in the Scott 14 pasture and the other half were released into a s~milar cage at the Howarth pasture o Both cages enclosed about 30 ft of natural turf and each was supplied with fresh dung (beetle food) until no beetles were present These two cages were monitored for the re-eppearance of beetles from September through December and cattle droppings from various pastures were sampled for the presence of naturally appearing wild beetles

During the past year the first beetles appeared in pasture droppings on November 4 when the dung peds had an average of 27 beetlespad On different weeks from November 11 through December 11 the density of ~ fimetarius remained fairly stable at 29 21 23 end 25 beetlespad As in previous years the beetle density then began to decline with 15pad on December 15 and less than one per pad on January 7 1982 In the Fall of 1981 beetles that had been marked and released into the experimental cages first appeared in the Scott 14 pasture on November 9 5 days after beetles first appeared in cattle dung pads in pastures The marked beetles contshyinued to appear in the Scott 14 cage through December with one beetle last appearing on December 16 No beetles were recovered in the Howarth pasture cage and through December 16 only 1 of marked beetles had been recovered in the Scott 14 cage This is in marked contrast to the cage recapture rates of 57 in the Scott pasture and 104 in the Howarth pasture It appears that beetles marked with the fluorescent dust suffershyed heavy mortality most of the marked beetles recovered had only a few particles of dust under the elytra or under the membraneous wings Nevertheless recapture of marked beetles confirmed that ~ fimetarius naturally hibernates (aestivates) in the ground for about 5 months in this part of California Other methods of marking beetles will be tested during the next seaSon

The objectives of this research were outlined in the 1980 report Many of the same trends observed in 1980 were repeated in 1981 Body weights of the cows were positively related to level of supplementation

(Table 1) The greatest effect was observed at the start of the breeding season where the difference between the unsupplemented and 25 times supplemented cows was nearly 100 kg

Weaning weight of the calves (Table 2) reflected the plane of nutrition of the cows Although weaning weights were enhanced by supplementation the largest differences in body weights occurred at the times the dams were mated Body weights of the calves reflected differential milk production of the cows

As in the previous year birth weight of the calves was not affected by plane of nutrition of the cows

6 Progress Report (Progress during report period toward reaching objectives of this research)

The major objectives of this research with Hereford cattle are (1) to determine if individual differences in mounting frequency by juvenile males correlate with individual differences in sexual motivation and performance as adults (2) to determine the degree of correlation between sexual behaviors and other biological traits (eg aggressive behavior semen characteristics hormone levels body size scrotal circumference) (3) to determine the function of mounting exshyperience on the development of sexual behavior and (4) to determine the role of penile stimulation on the development of sexual behavior

Over the last 4 years 78 bulls have been obtained from the SFRFS herd to investigate these questions Twenty-four male calves were brought to Davis from SFRFS in May 1981 to be used in studying objective 114 No observations were made on this group at the Field Station

Prior to 1981 all of our observations on juvenile mounting (Objectives 1 and 3) were made in confined situations where estrous heifers were provided as mountingstimuli and inter-animal contacts were frequent To determine the frequency of juvenile mounting in a more typical range environment 10 male and 9 female purebredHereford calves were observed between January 13 and March 22 1981 for a total of 40 hrs (29 different days) The calves ranged in age from 48 to 102 days (x = 80 days) at the start of observation A total of 394 calf observation hours were made on the 10 bull calves in the group and 749 calf hours on all 19 calves

Relative to our studies in confinement the rate of juvenile mounting in a typical range environment is very low A total of 15 mount intentions 12 mount attempts and 6 mounts (33 mount responses) were observed during the 40 hrs of observation Except for one mount intention all of the mounting activities were exhibited by bull calves The rate of mount responses was 0084 per bull calf per hour of observation Nearly all of the mounting behaviors were observed near the feed trough following feeding of supplements Supplemental feeding was terminated on February 25th and no sexual activity was observed among calves after that date

It was concluded that the mounting experience of 2-12 to 4-12 mo juvenilecalves in a ranqe environment is very limited

promising at present arc Monterey pine coast redwood and varieties of Pinus halepensis (brutia and eldarica) The most promising hardwoods to date are Eucalyptus globulus camaldulensis (2 variants) urnigera and grandis

In the lower Plot near the Yuba River deer and cattle damage al1d some porcupine debarking have greatly reduced the choice of species here The above pines Arizona cypress plus possibly tamarisk aphylla and coast redwood still appear promising

The North Plot after 3 years of trial plantings versus 4 for the other plots shows promising results for only Arizona cypress Eucalyptus grandis from 2 sources and tamarisk aphylla It is too early to rate the remainj~g species over-all survival rates of which are generally low

No fertilizer tablets have been applied to any of these plots because other factors limiting growth and survival appear more Important There was no serious rodent or insect damage noted in any of the 3 plots this past year and irrigation practices have been generally good probably supplying around 3 acre feet per growing season of about 6 months

It is now planned to establish semi-commercial plots of a minimum of 112 acre for each of at least 5 of the most promising species in another area of the Sierra Field Station

Development work continued in the Campbell Field A fall-1980 seeding of a perennia grass-legume pasture mixture on the new irrigated pasture areas was successful except for parts of some fields where irrigation water (surface flow) failed to reach In general the newly-installed irrigation system performed well

The following work was done on or related to the range fertilization study being conducted on the Forbes Flll44 series fields

a Soil samples were taken from each of the 16 fields Analyses will be made for P 5 Ca Mg K and pH

b In cooperation with M B Jones (HFS) field plots were established at eight locations (4 north-facing aspects 4 south-facing) A factorial design was used to compare 4 levels of N (as urea) and 4 levels of P (as low-S concentrated superphosphate) plus an exploratory for several combinations of NPS with two replications at each locati r

c Also in cooperation with M B Jones a greenhouse pot test was set up at the Hopland Field station with rate-element combinations to match those in the field plots using soil collected at the field locations for the eight replications The pots were seeded with a mixture of sub and rose clovers together with soft chess

d M R George and W J Clawson located sites for a grazing utilization study employing 10 x 10 exclosures

e A field-scale experiment with aerial application of nitrogen (as urea) at 0 40 80 and 120 kgha rates (two fields per replication two replications per treatment) is planned for fall 1982 following evaluation of the tests described above and results of a pre-experiment calibration grazing (with steers) beginning February 1982 Roy Hull J G Morris and R E Delmas are cooperators from the Department of Animal Science

This is the third year in which numbers of infective parasite larvae on pasture has been assessed by placing 2 worm-free tracer calves on pasture at monthly intervals Since this is only one of several locations where these studies are being conducted not all laboratory analyses have been completedNevertheless studies over the three year period demonstrates the occurrence of infective nematode larvae on pastures is repetitive and predictable The season for the occurrence of disease producing numbers of various species differs little in such diverse regions as the San Joaquin Valley (Elk Grove) the East Slope of the Sierras (Susanville) or the Sierra Foothills (UCSFR) This studycorroborates the newly emerging concepts of safe and unsafe grazing periods The application of data from this study can be utilized in managerial decisions and thus in Integrated Pest (parasite) Control programs It is planned that trials designed to establish the value of these IPC programs will be initiated at several locations including UCSFR during the 1981-82 year

6 Progress Report (Progress during report period toward reaching objectives of this research)

Four pairs of 14 acre plots were established during the fall of 1979 The Blue Oak overstory of these paired plots was approximately 0 25 50 and 75 The tree overstory was removed from one set of four plots by February 15 1980 and 12 wire mesh igloo type cages were placed on all plots by December 1980 Cages were located under tree canopy (or former tree canopy) and in the open using a stratified random procedure with proportional allocation

During 1981 three successive clippings were taken from inside the wire cages to determine the total standing crop present on February 21 (early season) April 3 amp 4 (mid-season) and June 2 (late season)

Preliminary Results (1981)

Uncleared plots 25 50 and 75 overstory cover Standing crop at any season did not differ appreciably by overstory level (Fig 1) When compared with uncleared open (0 overstory cover) plots standing crop was significantly less in uncleared plots at late season but not at early and mid-season Overstory cover and standing crop are not significantly correlated for any season (Fig 2)

Cleared Plots 25 50 and 75 prior overstory cover Standing crop is positively correlated with prior overstory cover particularly when uncleared open (0 overstory cover) plots are included in the comparison (Fig 2)

Tree removal greatly increased standing crop at all three seasons of harvest for all overstory cover levels (Fig 1) When compared to uncleared plots of the same overstory cover level these increases were 100 early season 133 midshyseason and 80 late season

During the first phase of the trial we are observing tropical plants Varieties were I isted in last year1s report The Leucaena species was eliminated Last winter was a relatively mild winter thus we feel we did not obtain good cold readings on the other species Further observations will be made this coming year

In the second phase we have planted species and varieties of Orchardgrass Tall Fescue and Perennial Ryegrass from the Georgia Plant Station In addition planted species of the same plants used in California irrigated pastures Stand evaluations were made on all species this past year only This coming year we will obtain yield data

The major objective of this study is to determine differences in the maternal care provided tw1n calves relative to the maternal behavior of cows with singleoffspring when placed 1n a range environment Observations were conducted duringJanuary February and March 1981 at SFRFS on 7 cows with single calves and 5 cows with twins housed in a 75A pasture The animals were observed for 15 hrs per week during the f1rst two hrs following sunrise and the two hrs preceding sunset

Data collected on mothers included frequency and duration of licking (grooming) calves vocalizattons butts and butt attempts directed at alien calves and behavioral responses to separatton from calf(ves) Calves were observed for frequency and duration of sucking on own and aUen mothers frequency and duration of resting runn1ng laying and grazing frequency of vocalizations and juvenilemounting and prox1m1ty to mother tw1n and nea~est unrelated calf

The data have been compiled but have not yet been analyzed statistically

Efficacy of sall as a vehicle for selenium supplementatio~

6 Progress Report (Progress during report period toward reaching objectives of this research)

This experiment was undertaken to assess the efficacy and safety of a salt selenium mixture for supplementing range cows

Approximately a years data have been obtained on two groups each of 19 mature Hereford cows grazing range and offered two salt-selenium mineral mixtures free choice The concentration of selenium in one mixture was 40 ppm (low Se group) and the other 80 ppm (high Se group) These levels represent 2 and 4 times the maximal level currently permitted by FDA

Blood selenium concentrations (Figure 1) were determined on each animal at weekly intervals initially then at monthy intervals Intake of the salt-selenium mixture was also measured at monthly intervals to obtain total group mean intake of selenium

Blood selenium concentration rose from the initial concentration of 0035 ~gml to a maxima of approximately 0225 ~gm1 in the high group and 0150 ~gm1 in the low group at about 12 weeks Then maximal concentrations are within the range of normality and in no way indicate selenium toxicity

Intake of the salt-selenium mixture was not well correlated with blood concentration of se1eniUffl

Then data indicate that the FDA maximal level of 20 ppm selenium in salt supplements is conservative and may be ineffectual in areas of selenium deficiency There was no significant difference in the weight of the cows at the time the calves were weaned - low group 487 ~ 48 kg high group - 481 ~ 57 kg

SlJotMARY OF COMMENTS

The foothills of California offer an ideal place for people

to pursue farming Farming in the tradi tional sense family cerltered

labor interlsive small machinery oriented conservation minded small

Hopefully the U C Sierra Foothill Range Field Station will accept

and meet the challenge of providing research and information appropriate

to the fledgling development of a foothill agriculture ethic in which

the quality of food and living is paramount Projects of this nature

are few in the 1981 annual report Possibly we can make II greeter

contribution to foothill farming in the future

Evaluation of Ectiban Formulations For Fly Control on Cattle U C Sierra Foothill Range Field Station California 1981

E C Loomis PhD Parasitologist Lorry L Dunning Staff Research Associate

Extension Veterinary Medicine University of California Davis 95616

INTRODUCTION

Sixty (60)- Hereford heifers (avg wt4Q0 lbs) maintained on irrigated pasture at the U C Field Station were used for a fly control trial using Ectiban Pour~On and~Ectiban insecticide Ear Tag Tapes The heifers were divided into 6 equal groups of 10 each and were identified as groups 1 to 6 Twenty-five heifers of similar age and weight were kept on dry rangeland about 12 mile distant and served as Group 7 for a control (untreated) All 85 heifers were rated for horn fly densities in corrals prior to group separation and treatment but face fly counts were made in the field one week later

MATERIALS AND PROCEDURES

Ectiban formulations for trial evaluation consisted of a ready-to-use 1 Permethrin Pour-On (GFU003 Red 6766 dated 32481) and I-gram active ingredient Permethrin Ear Tag tapes for application to cattle ear tags These formulations were compared to a standard registered 005 spray using Coopertox Extra (Toxaphene 45 Lindane 196gt

Ectiban Pour-On was applied by means of 4 oz capacity metal dippers to 4 groups at a dosage of 12 ozcwt initially on June 10 and retreated on August 3 Groups 1 and 4 received a backline application while groups 2 and 5 received a face and poll application Groups 3 and 6 were sprayed over the entire body on June 10 and only Group 6 W4S resprayed on September 30 using 12 gallon (70 ozgt of Coopertox solution per head from a U C power sprayer equipped with a 6 HP Briggs amp Stratton engine plus by-pass pump system operated at 300 psi

Ectiban Ear Tag tapes for ear tag application arrived midway through the trial and some of the groups were split for tape application when retreatment was indicated on September 2 Groups 2 and 3 received one tape per heifer attached around the neck of the ear tag and Group I had a tape wrapped around the _end of the tail (above the switch) and secured with adhesive duct tape Groups 4 to 6 were not retreated at this time in order to determine possible effects of fly control from Ectiban-taped heifers which shared common fence lines and

2

exposure with the 3 Groups Following observations on September 23 it was decided to retreat Groups 4 to 6 on September 30 using the same Pour-On and Spray regimen as applied at the start of the trial

Visual fly counts by eye or with the aid of 7 x 50 binoculars were made in most cases by one observer on all 10 heifers in each of 6 Groups and on 10 of the 25 heifers in control Group 7 Counts were made from lOAM to 2PM at weekly intervals Horn fly counts (H irritans) were made on flies resting on one side of the body (withers ribcage and upper legs) and on Face flies (M autumnalis) resting on the face and head area

O~e way analysis of variance was used to determine if overall trea-tment means varied significantly Fishers LSD method was used to compare where differences occurred between treatment means

RESULTS AND DISCUSSION

The results on Horn fly control are shown in Table 1 Excellent control was obtained for 4 weeks (June 10 to July 7) for Ectiban backline Pour-On to Groups 1 and 4 while excellent to good control resulted from Ectiban face Pour-on on Groups 2 and 5 for the same 4 weeks Coopertox spray on Groups 3 and 6 provided excellent control for only 2 weeks (June 10 to 24) Surprisingly retreatment of the 4 Ectiban groups on August 2 provided not more than 2 weeks of satisfactory control Of equal interest was the dramatic decrease in horn flies for two weeks on Group 3 but only slightly so on Group 6 both of which were intentionally not resprayed with Coopertox on August 2 There was no significant difference between Ectiban Pour-On to the backline or to the face nor between these treatments and the Coopertox body spray as determined from mean totals on Horn fly populations for the entire trial period June 10 to October 17 all three treatments reduced horn flies significantly better (P lt 0005) than the control (Table 3)

Also included in Table 1 are the results for horn fly control following Ectiban Tape applications on September 2 Excellent control resulted for 4 weeks on taped-heifers in Groups 1 2 and 3 No significant difference occurred between tape treatments to the ear or tail but all 3 treatment groups showed significant fly reduction (P lt 0005) when compared to the control group (Table 4) Fly populations in control Group 7 decreased rapidly with the onset of cold nights during the week of October 10

The results on Face fly control are shown in Table 2 Relatively good control of this species occurred with the Pour-On treatments for about 2 weeks (June 10 to 24) -with almost similar results for the Coopertox spray Fly control on these same groups retreated on August 3 provided a shorter

period of control about 9 to 1i days the natural dccro(1s(~ in Face fly popula tion s dur i ng Ju 1 and Augus t as ev idenct~d in Control Group 7 is commonplace and fly numbers are too low to warrant reliable comparison witn treated animals There was no significant difference between the Ectiban Pour-On to the face or to the backlinebut both treatments -were significantly different (P lt 0005) than the Coopertox spray and the control (Table 3)

Also included in Table 2 are the results for Face fly control following Ectiban tape applications on September 2 Excellent (Group 2) to good (Group 3) control resulted one day after application with tapes applied to ear tags but control did not persist at a satisfactory level as evidenced by the increase in fly counts on September 9 there was poor control via tapes attached to the tail (Group 1) The poor significance of these results are shown in Table 4 Poor results were obtained on face fly ~ontrol upon retreatment of Groups 41 and 50n September 30 and similar JesuIts were evident on Group 6 which was resprayed wi th Co_opertlt~

Of interest in this trial were the results on Horn fly control from the small amount of Ectiban Pour-On to the face of animals Heretofore it was believed that a similar dose of a pesticide to the withers was more effective but if Face fly populations are the main target then face and head applications could serve a dual purpose to include Horn fly control

Early IrrIgation - Liquid Supplement Trial

RIck Delmas

This study was initiated In 1980 to study the performance of

cattle using liquid supplement and the effect of early irrigation of

annual grasslands for early fall growth on the performance of cattle

during the fall and winter grazing period

Though the trial needs to be continued for the next couple of

years the following are indicated from one years data

1) Early irrigation furnishes valuable early fall feed especially

in poor rainfall years

2) Liquid supplement doesnt appear to be as beneficial as concentrates

for young cattle during the fall and winter The conception rate

on cattle with only liquid supplement was 8 to 19 lower than on

the other three treatments Economically the liquid supplement

was half the cost or less of the concentrate excluding labor

From this sfandpoint alone a rancher may be wIlling to accept

a slightly lower conception rate to obtain the decreased labor

and supplement cost Each individual rancher must measure cost

versus production

EFFECT OF OAK TREE REMOVAL ON FORAGE PRODUCTION

1981 was the sixteenth year that forage production has been measured in this study I have considered terminating the measurements because yield increases have not been significant in three of the last four years (see table) However data show that increases were significant in all of the sixteen years in which forage production on the check treatment (area covered by live trees) was below the median of the period (1385 Ibacre) Therefore in the interest of economy only the check treatments will be sampled in high rainfall years If another poor feed year occurs soon we will measure all treatments

6 Progress Report (Progress uring report perio toward reaching objectives of this research) The Ecologv and Population Dynamics of Aphodius fimetarius

The ecological study of the dung beetle Aphodius fimetarius was continued by again monitoring the ability of males and females to hibshyernate (aestivate) from late Spring to Fall From May 29 through June 9 we collected and marked 3020 beetles with fluorescent dust Half of these were released into a beetle-proof screened field cage in the Scott 14 pasture and the other half were released into a s~milar cage at the Howarth pasture o Both cages enclosed about 30 ft of natural turf and each was supplied with fresh dung (beetle food) until no beetles were present These two cages were monitored for the re-eppearance of beetles from September through December and cattle droppings from various pastures were sampled for the presence of naturally appearing wild beetles

During the past year the first beetles appeared in pasture droppings on November 4 when the dung peds had an average of 27 beetlespad On different weeks from November 11 through December 11 the density of ~ fimetarius remained fairly stable at 29 21 23 end 25 beetlespad As in previous years the beetle density then began to decline with 15pad on December 15 and less than one per pad on January 7 1982 In the Fall of 1981 beetles that had been marked and released into the experimental cages first appeared in the Scott 14 pasture on November 9 5 days after beetles first appeared in cattle dung pads in pastures The marked beetles contshyinued to appear in the Scott 14 cage through December with one beetle last appearing on December 16 No beetles were recovered in the Howarth pasture cage and through December 16 only 1 of marked beetles had been recovered in the Scott 14 cage This is in marked contrast to the cage recapture rates of 57 in the Scott pasture and 104 in the Howarth pasture It appears that beetles marked with the fluorescent dust suffershyed heavy mortality most of the marked beetles recovered had only a few particles of dust under the elytra or under the membraneous wings Nevertheless recapture of marked beetles confirmed that ~ fimetarius naturally hibernates (aestivates) in the ground for about 5 months in this part of California Other methods of marking beetles will be tested during the next seaSon

6 Progress Report (Progress during report period toward reaching objectives of this research)

An evaluation was undertaken of the necessity for vitamin A supplementation of range cows

A group of 12 cows were grazed on range without access to irrigated pasture or B carotene supplements At monthly intervals over the past year liver biopsies were performed and blood collected for carotene and vitamin A determinations

At no time did circulating vitamin A concentrations indicate that supplementation was necessary

The relationship between hepatic reserves and circulating levels is being examined

The objectives of this research were outlined in the 1980 report Many of the same trends observed in 1980 were repeated in 1981 Body weights of the cows were positively related to level of supplementation

(Table 1) The greatest effect was observed at the start of the breeding season where the difference between the unsupplemented and 25 times supplemented cows was nearly 100 kg

Weaning weight of the calves (Table 2) reflected the plane of nutrition of the cows Although weaning weights were enhanced by supplementation the largest differences in body weights occurred at the times the dams were mated Body weights of the calves reflected differential milk production of the cows

As in the previous year birth weight of the calves was not affected by plane of nutrition of the cows

6 Progress Report (Progress during report period toward reaching objectives of this research)

The major objectives of this research with Hereford cattle are (1) to determine if individual differences in mounting frequency by juvenile males correlate with individual differences in sexual motivation and performance as adults (2) to determine the degree of correlation between sexual behaviors and other biological traits (eg aggressive behavior semen characteristics hormone levels body size scrotal circumference) (3) to determine the function of mounting exshyperience on the development of sexual behavior and (4) to determine the role of penile stimulation on the development of sexual behavior

Over the last 4 years 78 bulls have been obtained from the SFRFS herd to investigate these questions Twenty-four male calves were brought to Davis from SFRFS in May 1981 to be used in studying objective 114 No observations were made on this group at the Field Station

Prior to 1981 all of our observations on juvenile mounting (Objectives 1 and 3) were made in confined situations where estrous heifers were provided as mountingstimuli and inter-animal contacts were frequent To determine the frequency of juvenile mounting in a more typical range environment 10 male and 9 female purebredHereford calves were observed between January 13 and March 22 1981 for a total of 40 hrs (29 different days) The calves ranged in age from 48 to 102 days (x = 80 days) at the start of observation A total of 394 calf observation hours were made on the 10 bull calves in the group and 749 calf hours on all 19 calves

Relative to our studies in confinement the rate of juvenile mounting in a typical range environment is very low A total of 15 mount intentions 12 mount attempts and 6 mounts (33 mount responses) were observed during the 40 hrs of observation Except for one mount intention all of the mounting activities were exhibited by bull calves The rate of mount responses was 0084 per bull calf per hour of observation Nearly all of the mounting behaviors were observed near the feed trough following feeding of supplements Supplemental feeding was terminated on February 25th and no sexual activity was observed among calves after that date

It was concluded that the mounting experience of 2-12 to 4-12 mo juvenilecalves in a ranqe environment is very limited

In the lower Plot near the Yuba River deer and cattle damage al1d some porcupine debarking have greatly reduced the choice of species here The above pines Arizona cypress plus possibly tamarisk aphylla and coast redwood still appear promising

The North Plot after 3 years of trial plantings versus 4 for the other plots shows promising results for only Arizona cypress Eucalyptus grandis from 2 sources and tamarisk aphylla It is too early to rate the remainj~g species over-all survival rates of which are generally low

No fertilizer tablets have been applied to any of these plots because other factors limiting growth and survival appear more Important There was no serious rodent or insect damage noted in any of the 3 plots this past year and irrigation practices have been generally good probably supplying around 3 acre feet per growing season of about 6 months

It is now planned to establish semi-commercial plots of a minimum of 112 acre for each of at least 5 of the most promising species in another area of the Sierra Field Station

Development work continued in the Campbell Field A fall-1980 seeding of a perennia grass-legume pasture mixture on the new irrigated pasture areas was successful except for parts of some fields where irrigation water (surface flow) failed to reach In general the newly-installed irrigation system performed well

The following work was done on or related to the range fertilization study being conducted on the Forbes Flll44 series fields

a Soil samples were taken from each of the 16 fields Analyses will be made for P 5 Ca Mg K and pH

b In cooperation with M B Jones (HFS) field plots were established at eight locations (4 north-facing aspects 4 south-facing) A factorial design was used to compare 4 levels of N (as urea) and 4 levels of P (as low-S concentrated superphosphate) plus an exploratory for several combinations of NPS with two replications at each locati r

c Also in cooperation with M B Jones a greenhouse pot test was set up at the Hopland Field station with rate-element combinations to match those in the field plots using soil collected at the field locations for the eight replications The pots were seeded with a mixture of sub and rose clovers together with soft chess

d M R George and W J Clawson located sites for a grazing utilization study employing 10 x 10 exclosures

e A field-scale experiment with aerial application of nitrogen (as urea) at 0 40 80 and 120 kgha rates (two fields per replication two replications per treatment) is planned for fall 1982 following evaluation of the tests described above and results of a pre-experiment calibration grazing (with steers) beginning February 1982 Roy Hull J G Morris and R E Delmas are cooperators from the Department of Animal Science

6 Progress Report (Progress during report period toward reaching objectives of this research)

Four pairs of 14 acre plots were established during the fall of 1979 The Blue Oak overstory of these paired plots was approximately 0 25 50 and 75 The tree overstory was removed from one set of four plots by February 15 1980 and 12 wire mesh igloo type cages were placed on all plots by December 1980 Cages were located under tree canopy (or former tree canopy) and in the open using a stratified random procedure with proportional allocation

During 1981 three successive clippings were taken from inside the wire cages to determine the total standing crop present on February 21 (early season) April 3 amp 4 (mid-season) and June 2 (late season)

Preliminary Results (1981)

Uncleared plots 25 50 and 75 overstory cover Standing crop at any season did not differ appreciably by overstory level (Fig 1) When compared with uncleared open (0 overstory cover) plots standing crop was significantly less in uncleared plots at late season but not at early and mid-season Overstory cover and standing crop are not significantly correlated for any season (Fig 2)

Cleared Plots 25 50 and 75 prior overstory cover Standing crop is positively correlated with prior overstory cover particularly when uncleared open (0 overstory cover) plots are included in the comparison (Fig 2)

Tree removal greatly increased standing crop at all three seasons of harvest for all overstory cover levels (Fig 1) When compared to uncleared plots of the same overstory cover level these increases were 100 early season 133 midshyseason and 80 late season

6 Progress Report (Progress during report period toward reaching objectives of this research)

This experiment was undertaken to assess the efficacy and safety of a salt selenium mixture for supplementing range cows

Approximately a years data have been obtained on two groups each of 19 mature Hereford cows grazing range and offered two salt-selenium mineral mixtures free choice The concentration of selenium in one mixture was 40 ppm (low Se group) and the other 80 ppm (high Se group) These levels represent 2 and 4 times the maximal level currently permitted by FDA

Blood selenium concentrations (Figure 1) were determined on each animal at weekly intervals initially then at monthy intervals Intake of the salt-selenium mixture was also measured at monthly intervals to obtain total group mean intake of selenium

Blood selenium concentration rose from the initial concentration of 0035 ~gml to a maxima of approximately 0225 ~gm1 in the high group and 0150 ~gm1 in the low group at about 12 weeks Then maximal concentrations are within the range of normality and in no way indicate selenium toxicity

Intake of the salt-selenium mixture was not well correlated with blood concentration of se1eniUffl

Then data indicate that the FDA maximal level of 20 ppm selenium in salt supplements is conservative and may be ineffectual in areas of selenium deficiency There was no significant difference in the weight of the cows at the time the calves were weaned - low group 487 ~ 48 kg high group - 481 ~ 57 kg

The foothills of California offer an ideal place for people

to pursue farming Farming in the tradi tional sense family cerltered

labor interlsive small machinery oriented conservation minded small

Hopefully the U C Sierra Foothill Range Field Station will accept

and meet the challenge of providing research and information appropriate

to the fledgling development of a foothill agriculture ethic in which

the quality of food and living is paramount Projects of this nature

are few in the 1981 annual report Possibly we can make II greeter

contribution to foothill farming in the future

Evaluation of Ectiban Formulations For Fly Control on Cattle U C Sierra Foothill Range Field Station California 1981

E C Loomis PhD Parasitologist Lorry L Dunning Staff Research Associate

Extension Veterinary Medicine University of California Davis 95616

INTRODUCTION

Sixty (60)- Hereford heifers (avg wt4Q0 lbs) maintained on irrigated pasture at the U C Field Station were used for a fly control trial using Ectiban Pour~On and~Ectiban insecticide Ear Tag Tapes The heifers were divided into 6 equal groups of 10 each and were identified as groups 1 to 6 Twenty-five heifers of similar age and weight were kept on dry rangeland about 12 mile distant and served as Group 7 for a control (untreated) All 85 heifers were rated for horn fly densities in corrals prior to group separation and treatment but face fly counts were made in the field one week later

MATERIALS AND PROCEDURES

Ectiban formulations for trial evaluation consisted of a ready-to-use 1 Permethrin Pour-On (GFU003 Red 6766 dated 32481) and I-gram active ingredient Permethrin Ear Tag tapes for application to cattle ear tags These formulations were compared to a standard registered 005 spray using Coopertox Extra (Toxaphene 45 Lindane 196gt

Ectiban Pour-On was applied by means of 4 oz capacity metal dippers to 4 groups at a dosage of 12 ozcwt initially on June 10 and retreated on August 3 Groups 1 and 4 received a backline application while groups 2 and 5 received a face and poll application Groups 3 and 6 were sprayed over the entire body on June 10 and only Group 6 W4S resprayed on September 30 using 12 gallon (70 ozgt of Coopertox solution per head from a U C power sprayer equipped with a 6 HP Briggs amp Stratton engine plus by-pass pump system operated at 300 psi

Ectiban Ear Tag tapes for ear tag application arrived midway through the trial and some of the groups were split for tape application when retreatment was indicated on September 2 Groups 2 and 3 received one tape per heifer attached around the neck of the ear tag and Group I had a tape wrapped around the _end of the tail (above the switch) and secured with adhesive duct tape Groups 4 to 6 were not retreated at this time in order to determine possible effects of fly control from Ectiban-taped heifers which shared common fence lines and

2

exposure with the 3 Groups Following observations on September 23 it was decided to retreat Groups 4 to 6 on September 30 using the same Pour-On and Spray regimen as applied at the start of the trial

Visual fly counts by eye or with the aid of 7 x 50 binoculars were made in most cases by one observer on all 10 heifers in each of 6 Groups and on 10 of the 25 heifers in control Group 7 Counts were made from lOAM to 2PM at weekly intervals Horn fly counts (H irritans) were made on flies resting on one side of the body (withers ribcage and upper legs) and on Face flies (M autumnalis) resting on the face and head area

O~e way analysis of variance was used to determine if overall trea-tment means varied significantly Fishers LSD method was used to compare where differences occurred between treatment means

RESULTS AND DISCUSSION

The results on Horn fly control are shown in Table 1 Excellent control was obtained for 4 weeks (June 10 to July 7) for Ectiban backline Pour-On to Groups 1 and 4 while excellent to good control resulted from Ectiban face Pour-on on Groups 2 and 5 for the same 4 weeks Coopertox spray on Groups 3 and 6 provided excellent control for only 2 weeks (June 10 to 24) Surprisingly retreatment of the 4 Ectiban groups on August 2 provided not more than 2 weeks of satisfactory control Of equal interest was the dramatic decrease in horn flies for two weeks on Group 3 but only slightly so on Group 6 both of which were intentionally not resprayed with Coopertox on August 2 There was no significant difference between Ectiban Pour-On to the backline or to the face nor between these treatments and the Coopertox body spray as determined from mean totals on Horn fly populations for the entire trial period June 10 to October 17 all three treatments reduced horn flies significantly better (P lt 0005) than the control (Table 3)

Also included in Table 1 are the results for horn fly control following Ectiban Tape applications on September 2 Excellent control resulted for 4 weeks on taped-heifers in Groups 1 2 and 3 No significant difference occurred between tape treatments to the ear or tail but all 3 treatment groups showed significant fly reduction (P lt 0005) when compared to the control group (Table 4) Fly populations in control Group 7 decreased rapidly with the onset of cold nights during the week of October 10

The results on Face fly control are shown in Table 2 Relatively good control of this species occurred with the Pour-On treatments for about 2 weeks (June 10 to 24) -with almost similar results for the Coopertox spray Fly control on these same groups retreated on August 3 provided a shorter

period of control about 9 to 1i days the natural dccro(1s(~ in Face fly popula tion s dur i ng Ju 1 and Augus t as ev idenct~d in Control Group 7 is commonplace and fly numbers are too low to warrant reliable comparison witn treated animals There was no significant difference between the Ectiban Pour-On to the face or to the backlinebut both treatments -were significantly different (P lt 0005) than the Coopertox spray and the control (Table 3)

Also included in Table 2 are the results for Face fly control following Ectiban tape applications on September 2 Excellent (Group 2) to good (Group 3) control resulted one day after application with tapes applied to ear tags but control did not persist at a satisfactory level as evidenced by the increase in fly counts on September 9 there was poor control via tapes attached to the tail (Group 1) The poor significance of these results are shown in Table 4 Poor results were obtained on face fly ~ontrol upon retreatment of Groups 41 and 50n September 30 and similar JesuIts were evident on Group 6 which was resprayed wi th Co_opertlt~

Of interest in this trial were the results on Horn fly control from the small amount of Ectiban Pour-On to the face of animals Heretofore it was believed that a similar dose of a pesticide to the withers was more effective but if Face fly populations are the main target then face and head applications could serve a dual purpose to include Horn fly control

Early IrrIgation - Liquid Supplement Trial

RIck Delmas

This study was initiated In 1980 to study the performance of

cattle using liquid supplement and the effect of early irrigation of

annual grasslands for early fall growth on the performance of cattle

during the fall and winter grazing period

Though the trial needs to be continued for the next couple of

years the following are indicated from one years data

1) Early irrigation furnishes valuable early fall feed especially

in poor rainfall years

2) Liquid supplement doesnt appear to be as beneficial as concentrates

for young cattle during the fall and winter The conception rate

on cattle with only liquid supplement was 8 to 19 lower than on

the other three treatments Economically the liquid supplement

was half the cost or less of the concentrate excluding labor

From this sfandpoint alone a rancher may be wIlling to accept

a slightly lower conception rate to obtain the decreased labor

and supplement cost Each individual rancher must measure cost

versus production

EFFECT OF OAK TREE REMOVAL ON FORAGE PRODUCTION

1981 was the sixteenth year that forage production has been measured in this study I have considered terminating the measurements because yield increases have not been significant in three of the last four years (see table) However data show that increases were significant in all of the sixteen years in which forage production on the check treatment (area covered by live trees) was below the median of the period (1385 Ibacre) Therefore in the interest of economy only the check treatments will be sampled in high rainfall years If another poor feed year occurs soon we will measure all treatments

6 Progress Report (Progress uring report perio toward reaching objectives of this research) The Ecologv and Population Dynamics of Aphodius fimetarius

The ecological study of the dung beetle Aphodius fimetarius was continued by again monitoring the ability of males and females to hibshyernate (aestivate) from late Spring to Fall From May 29 through June 9 we collected and marked 3020 beetles with fluorescent dust Half of these were released into a beetle-proof screened field cage in the Scott 14 pasture and the other half were released into a s~milar cage at the Howarth pasture o Both cages enclosed about 30 ft of natural turf and each was supplied with fresh dung (beetle food) until no beetles were present These two cages were monitored for the re-eppearance of beetles from September through December and cattle droppings from various pastures were sampled for the presence of naturally appearing wild beetles

During the past year the first beetles appeared in pasture droppings on November 4 when the dung peds had an average of 27 beetlespad On different weeks from November 11 through December 11 the density of ~ fimetarius remained fairly stable at 29 21 23 end 25 beetlespad As in previous years the beetle density then began to decline with 15pad on December 15 and less than one per pad on January 7 1982 In the Fall of 1981 beetles that had been marked and released into the experimental cages first appeared in the Scott 14 pasture on November 9 5 days after beetles first appeared in cattle dung pads in pastures The marked beetles contshyinued to appear in the Scott 14 cage through December with one beetle last appearing on December 16 No beetles were recovered in the Howarth pasture cage and through December 16 only 1 of marked beetles had been recovered in the Scott 14 cage This is in marked contrast to the cage recapture rates of 57 in the Scott pasture and 104 in the Howarth pasture It appears that beetles marked with the fluorescent dust suffershyed heavy mortality most of the marked beetles recovered had only a few particles of dust under the elytra or under the membraneous wings Nevertheless recapture of marked beetles confirmed that ~ fimetarius naturally hibernates (aestivates) in the ground for about 5 months in this part of California Other methods of marking beetles will be tested during the next seaSon

The objectives of this research were outlined in the 1980 report Many of the same trends observed in 1980 were repeated in 1981 Body weights of the cows were positively related to level of supplementation

(Table 1) The greatest effect was observed at the start of the breeding season where the difference between the unsupplemented and 25 times supplemented cows was nearly 100 kg

Weaning weight of the calves (Table 2) reflected the plane of nutrition of the cows Although weaning weights were enhanced by supplementation the largest differences in body weights occurred at the times the dams were mated Body weights of the calves reflected differential milk production of the cows

As in the previous year birth weight of the calves was not affected by plane of nutrition of the cows

6 Progress Report (Progress during report period toward reaching objectives of this research)

The major objectives of this research with Hereford cattle are (1) to determine if individual differences in mounting frequency by juvenile males correlate with individual differences in sexual motivation and performance as adults (2) to determine the degree of correlation between sexual behaviors and other biological traits (eg aggressive behavior semen characteristics hormone levels body size scrotal circumference) (3) to determine the function of mounting exshyperience on the development of sexual behavior and (4) to determine the role of penile stimulation on the development of sexual behavior

Over the last 4 years 78 bulls have been obtained from the SFRFS herd to investigate these questions Twenty-four male calves were brought to Davis from SFRFS in May 1981 to be used in studying objective 114 No observations were made on this group at the Field Station

Prior to 1981 all of our observations on juvenile mounting (Objectives 1 and 3) were made in confined situations where estrous heifers were provided as mountingstimuli and inter-animal contacts were frequent To determine the frequency of juvenile mounting in a more typical range environment 10 male and 9 female purebredHereford calves were observed between January 13 and March 22 1981 for a total of 40 hrs (29 different days) The calves ranged in age from 48 to 102 days (x = 80 days) at the start of observation A total of 394 calf observation hours were made on the 10 bull calves in the group and 749 calf hours on all 19 calves

Relative to our studies in confinement the rate of juvenile mounting in a typical range environment is very low A total of 15 mount intentions 12 mount attempts and 6 mounts (33 mount responses) were observed during the 40 hrs of observation Except for one mount intention all of the mounting activities were exhibited by bull calves The rate of mount responses was 0084 per bull calf per hour of observation Nearly all of the mounting behaviors were observed near the feed trough following feeding of supplements Supplemental feeding was terminated on February 25th and no sexual activity was observed among calves after that date

It was concluded that the mounting experience of 2-12 to 4-12 mo juvenilecalves in a ranqe environment is very limited

promising at present arc Monterey pine coast redwood and varieties of Pinus halepensis (brutia and eldarica) The most promising hardwoods to date are Eucalyptus globulus camaldulensis (2 variants) urnigera and grandis

In the lower Plot near the Yuba River deer and cattle damage al1d some porcupine debarking have greatly reduced the choice of species here The above pines Arizona cypress plus possibly tamarisk aphylla and coast redwood still appear promising

The North Plot after 3 years of trial plantings versus 4 for the other plots shows promising results for only Arizona cypress Eucalyptus grandis from 2 sources and tamarisk aphylla It is too early to rate the remainj~g species over-all survival rates of which are generally low

No fertilizer tablets have been applied to any of these plots because other factors limiting growth and survival appear more Important There was no serious rodent or insect damage noted in any of the 3 plots this past year and irrigation practices have been generally good probably supplying around 3 acre feet per growing season of about 6 months

It is now planned to establish semi-commercial plots of a minimum of 112 acre for each of at least 5 of the most promising species in another area of the Sierra Field Station

Development work continued in the Campbell Field A fall-1980 seeding of a perennia grass-legume pasture mixture on the new irrigated pasture areas was successful except for parts of some fields where irrigation water (surface flow) failed to reach In general the newly-installed irrigation system performed well

The following work was done on or related to the range fertilization study being conducted on the Forbes Flll44 series fields

a Soil samples were taken from each of the 16 fields Analyses will be made for P 5 Ca Mg K and pH

b In cooperation with M B Jones (HFS) field plots were established at eight locations (4 north-facing aspects 4 south-facing) A factorial design was used to compare 4 levels of N (as urea) and 4 levels of P (as low-S concentrated superphosphate) plus an exploratory for several combinations of NPS with two replications at each locati r

c Also in cooperation with M B Jones a greenhouse pot test was set up at the Hopland Field station with rate-element combinations to match those in the field plots using soil collected at the field locations for the eight replications The pots were seeded with a mixture of sub and rose clovers together with soft chess

d M R George and W J Clawson located sites for a grazing utilization study employing 10 x 10 exclosures

6 Progress Report (Progress during report period toward reaching objectives of this research)

Four pairs of 14 acre plots were established during the fall of 1979 The Blue Oak overstory of these paired plots was approximately 0 25 50 and 75 The tree overstory was removed from one set of four plots by February 15 1980 and 12 wire mesh igloo type cages were placed on all plots by December 1980 Cages were located under tree canopy (or former tree canopy) and in the open using a stratified random procedure with proportional allocation

During 1981 three successive clippings were taken from inside the wire cages to determine the total standing crop present on February 21 (early season) April 3 amp 4 (mid-season) and June 2 (late season)

Preliminary Results (1981)

Uncleared plots 25 50 and 75 overstory cover Standing crop at any season did not differ appreciably by overstory level (Fig 1) When compared with uncleared open (0 overstory cover) plots standing crop was significantly less in uncleared plots at late season but not at early and mid-season Overstory cover and standing crop are not significantly correlated for any season (Fig 2)

Cleared Plots 25 50 and 75 prior overstory cover Standing crop is positively correlated with prior overstory cover particularly when uncleared open (0 overstory cover) plots are included in the comparison (Fig 2)

Tree removal greatly increased standing crop at all three seasons of harvest for all overstory cover levels (Fig 1) When compared to uncleared plots of the same overstory cover level these increases were 100 early season 133 midshyseason and 80 late season

During the first phase of the trial we are observing tropical plants Varieties were I isted in last year1s report The Leucaena species was eliminated Last winter was a relatively mild winter thus we feel we did not obtain good cold readings on the other species Further observations will be made this coming year

In the second phase we have planted species and varieties of Orchardgrass Tall Fescue and Perennial Ryegrass from the Georgia Plant Station In addition planted species of the same plants used in California irrigated pastures Stand evaluations were made on all species this past year only This coming year we will obtain yield data

The major objective of this study is to determine differences in the maternal care provided tw1n calves relative to the maternal behavior of cows with singleoffspring when placed 1n a range environment Observations were conducted duringJanuary February and March 1981 at SFRFS on 7 cows with single calves and 5 cows with twins housed in a 75A pasture The animals were observed for 15 hrs per week during the f1rst two hrs following sunrise and the two hrs preceding sunset

Data collected on mothers included frequency and duration of licking (grooming) calves vocalizattons butts and butt attempts directed at alien calves and behavioral responses to separatton from calf(ves) Calves were observed for frequency and duration of sucking on own and aUen mothers frequency and duration of resting runn1ng laying and grazing frequency of vocalizations and juvenilemounting and prox1m1ty to mother tw1n and nea~est unrelated calf

The data have been compiled but have not yet been analyzed statistically

Efficacy of sall as a vehicle for selenium supplementatio~

4 Project Leader J G Morri 5 1 5 bull Period Covered QL sectL - 1L A by this Report mo yr mo yr

6 Progress Report (Progress during report period toward reaching objectives of this research)

This experiment was undertaken to assess the efficacy and safety of a salt selenium mixture for supplementing range cows

Approximately a years data have been obtained on two groups each of 19 mature Hereford cows grazing range and offered two salt-selenium mineral mixtures free choice The concentration of selenium in one mixture was 40 ppm (low Se group) and the other 80 ppm (high Se group) These levels represent 2 and 4 times the maximal level currently permitted by FDA

Blood selenium concentrations (Figure 1) were determined on each animal at weekly intervals initially then at monthy intervals Intake of the salt-selenium mixture was also measured at monthly intervals to obtain total group mean intake of selenium

Blood selenium concentration rose from the initial concentration of 0035 ~gml to a maxima of approximately 0225 ~gm1 in the high group and 0150 ~gm1 in the low group at about 12 weeks Then maximal concentrations are within the range of normality and in no way indicate selenium toxicity

Intake of the salt-selenium mixture was not well correlated with blood concentration of se1eniUffl

Then data indicate that the FDA maximal level of 20 ppm selenium in salt supplements is conservative and may be ineffectual in areas of selenium deficiency There was no significant difference in the weight of the cows at the time the calves were weaned - low group 487 ~ 48 kg high group - 481 ~ 57 kg

SlJotMARY OF COMMENTS

The foothills of California offer an ideal place for people

to pursue farming Farming in the tradi tional sense family cerltered

labor interlsive small machinery oriented conservation minded small

Hopefully the U C Sierra Foothill Range Field Station will accept

and meet the challenge of providing research and information appropriate

to the fledgling development of a foothill agriculture ethic in which

the quality of food and living is paramount Projects of this nature

are few in the 1981 annual report Possibly we can make II greeter

contribution to foothill farming in the future

exposure with the 3 Groups Following observations on September 23 it was decided to retreat Groups 4 to 6 on September 30 using the same Pour-On and Spray regimen as applied at the start of the trial

Visual fly counts by eye or with the aid of 7 x 50 binoculars were made in most cases by one observer on all 10 heifers in each of 6 Groups and on 10 of the 25 heifers in control Group 7 Counts were made from lOAM to 2PM at weekly intervals Horn fly counts (H irritans) were made on flies resting on one side of the body (withers ribcage and upper legs) and on Face flies (M autumnalis) resting on the face and head area

O~e way analysis of variance was used to determine if overall trea-tment means varied significantly Fishers LSD method was used to compare where differences occurred between treatment means

RESULTS AND DISCUSSION

The results on Horn fly control are shown in Table 1 Excellent control was obtained for 4 weeks (June 10 to July 7) for Ectiban backline Pour-On to Groups 1 and 4 while excellent to good control resulted from Ectiban face Pour-on on Groups 2 and 5 for the same 4 weeks Coopertox spray on Groups 3 and 6 provided excellent control for only 2 weeks (June 10 to 24) Surprisingly retreatment of the 4 Ectiban groups on August 2 provided not more than 2 weeks of satisfactory control Of equal interest was the dramatic decrease in horn flies for two weeks on Group 3 but only slightly so on Group 6 both of which were intentionally not resprayed with Coopertox on August 2 There was no significant difference between Ectiban Pour-On to the backline or to the face nor between these treatments and the Coopertox body spray as determined from mean totals on Horn fly populations for the entire trial period June 10 to October 17 all three treatments reduced horn flies significantly better (P lt 0005) than the control (Table 3)

Also included in Table 1 are the results for horn fly control following Ectiban Tape applications on September 2 Excellent control resulted for 4 weeks on taped-heifers in Groups 1 2 and 3 No significant difference occurred between tape treatments to the ear or tail but all 3 treatment groups showed significant fly reduction (P lt 0005) when compared to the control group (Table 4) Fly populations in control Group 7 decreased rapidly with the onset of cold nights during the week of October 10

The results on Face fly control are shown in Table 2 Relatively good control of this species occurred with the Pour-On treatments for about 2 weeks (June 10 to 24) -with almost similar results for the Coopertox spray Fly control on these same groups retreated on August 3 provided a shorter

period of control about 9 to 1i days the natural dccro(1s(~ in Face fly popula tion s dur i ng Ju 1 and Augus t as ev idenct~d in Control Group 7 is commonplace and fly numbers are too low to warrant reliable comparison witn treated animals There was no significant difference between the Ectiban Pour-On to the face or to the backlinebut both treatments -were significantly different (P lt 0005) than the Coopertox spray and the control (Table 3)

Also included in Table 2 are the results for Face fly control following Ectiban tape applications on September 2 Excellent (Group 2) to good (Group 3) control resulted one day after application with tapes applied to ear tags but control did not persist at a satisfactory level as evidenced by the increase in fly counts on September 9 there was poor control via tapes attached to the tail (Group 1) The poor significance of these results are shown in Table 4 Poor results were obtained on face fly ~ontrol upon retreatment of Groups 41 and 50n September 30 and similar JesuIts were evident on Group 6 which was resprayed wi th Co_opertlt~

Of interest in this trial were the results on Horn fly control from the small amount of Ectiban Pour-On to the face of animals Heretofore it was believed that a similar dose of a pesticide to the withers was more effective but if Face fly populations are the main target then face and head applications could serve a dual purpose to include Horn fly control

Early IrrIgation - Liquid Supplement Trial

RIck Delmas

This study was initiated In 1980 to study the performance of

cattle using liquid supplement and the effect of early irrigation of

annual grasslands for early fall growth on the performance of cattle

during the fall and winter grazing period

Though the trial needs to be continued for the next couple of

years the following are indicated from one years data

1) Early irrigation furnishes valuable early fall feed especially

in poor rainfall years

2) Liquid supplement doesnt appear to be as beneficial as concentrates

for young cattle during the fall and winter The conception rate

on cattle with only liquid supplement was 8 to 19 lower than on

the other three treatments Economically the liquid supplement

was half the cost or less of the concentrate excluding labor

From this sfandpoint alone a rancher may be wIlling to accept

a slightly lower conception rate to obtain the decreased labor

and supplement cost Each individual rancher must measure cost

versus production

EFFECT OF OAK TREE REMOVAL ON FORAGE PRODUCTION

1981 was the sixteenth year that forage production has been measured in this study I have considered terminating the measurements because yield increases have not been significant in three of the last four years (see table) However data show that increases were significant in all of the sixteen years in which forage production on the check treatment (area covered by live trees) was below the median of the period (1385 Ibacre) Therefore in the interest of economy only the check treatments will be sampled in high rainfall years If another poor feed year occurs soon we will measure all treatments

6 Progress Report (Progress uring report perio toward reaching objectives of this research) The Ecologv and Population Dynamics of Aphodius fimetarius

The ecological study of the dung beetle Aphodius fimetarius was continued by again monitoring the ability of males and females to hibshyernate (aestivate) from late Spring to Fall From May 29 through June 9 we collected and marked 3020 beetles with fluorescent dust Half of these were released into a beetle-proof screened field cage in the Scott 14 pasture and the other half were released into a s~milar cage at the Howarth pasture o Both cages enclosed about 30 ft of natural turf and each was supplied with fresh dung (beetle food) until no beetles were present These two cages were monitored for the re-eppearance of beetles from September through December and cattle droppings from various pastures were sampled for the presence of naturally appearing wild beetles

During the past year the first beetles appeared in pasture droppings on November 4 when the dung peds had an average of 27 beetlespad On different weeks from November 11 through December 11 the density of ~ fimetarius remained fairly stable at 29 21 23 end 25 beetlespad As in previous years the beetle density then began to decline with 15pad on December 15 and less than one per pad on January 7 1982 In the Fall of 1981 beetles that had been marked and released into the experimental cages first appeared in the Scott 14 pasture on November 9 5 days after beetles first appeared in cattle dung pads in pastures The marked beetles contshyinued to appear in the Scott 14 cage through December with one beetle last appearing on December 16 No beetles were recovered in the Howarth pasture cage and through December 16 only 1 of marked beetles had been recovered in the Scott 14 cage This is in marked contrast to the cage recapture rates of 57 in the Scott pasture and 104 in the Howarth pasture It appears that beetles marked with the fluorescent dust suffershyed heavy mortality most of the marked beetles recovered had only a few particles of dust under the elytra or under the membraneous wings Nevertheless recapture of marked beetles confirmed that ~ fimetarius naturally hibernates (aestivates) in the ground for about 5 months in this part of California Other methods of marking beetles will be tested during the next seaSon

An evaluation was undertaken of the necessity for vitamin A supplementation of range cows

A group of 12 cows were grazed on range without access to irrigated pasture or B carotene supplements At monthly intervals over the past year liver biopsies were performed and blood collected for carotene and vitamin A determinations

At no time did circulating vitamin A concentrations indicate that supplementation was necessary

The relationship between hepatic reserves and circulating levels is being examined

6 Progress Report (Progress during report period toward reaching objectives of thi 5 research)

The objectives of this research were outlined in the 1980 report Many of the same trends observed in 1980 were repeated in 1981 Body weights of the cows were positively related to level of supplementation

(Table 1) The greatest effect was observed at the start of the breeding season where the difference between the unsupplemented and 25 times supplemented cows was nearly 100 kg

Shrunk all others full body weight

Weaning weight of the calves (Table 2) reflected the plane of nutrition of the cows Although weaning weights were enhanced by supplementation the largest differences in body weights occurred at the times the dams were mated Body weights of the calves reflected differential milk production of the cows

As in the previous year birth weight of the calves was not affected by plane of nutrition of the cows

6 Progress Report (Progress during report period toward reaching objectives of this research)

The major objectives of this research with Hereford cattle are (1) to determine if individual differences in mounting frequency by juvenile males correlate with individual differences in sexual motivation and performance as adults (2) to determine the degree of correlation between sexual behaviors and other biological traits (eg aggressive behavior semen characteristics hormone levels body size scrotal circumference) (3) to determine the function of mounting exshyperience on the development of sexual behavior and (4) to determine the role of penile stimulation on the development of sexual behavior

Over the last 4 years 78 bulls have been obtained from the SFRFS herd to investigate these questions Twenty-four male calves were brought to Davis from SFRFS in May 1981 to be used in studying objective 114 No observations were made on this group at the Field Station

Prior to 1981 all of our observations on juvenile mounting (Objectives 1 and 3) were made in confined situations where estrous heifers were provided as mountingstimuli and inter-animal contacts were frequent To determine the frequency of juvenile mounting in a more typical range environment 10 male and 9 female purebredHereford calves were observed between January 13 and March 22 1981 for a total of 40 hrs (29 different days) The calves ranged in age from 48 to 102 days (x = 80 days) at the start of observation A total of 394 calf observation hours were made on the 10 bull calves in the group and 749 calf hours on all 19 calves

Relative to our studies in confinement the rate of juvenile mounting in a typical range environment is very low A total of 15 mount intentions 12 mount attempts and 6 mounts (33 mount responses) were observed during the 40 hrs of observation Except for one mount intention all of the mounting activities were exhibited by bull calves The rate of mount responses was 0084 per bull calf per hour of observation Nearly all of the mounting behaviors were observed near the feed trough following feeding of supplements Supplemental feeding was terminated on February 25th and no sexual activity was observed among calves after that date

It was concluded that the mounting experience of 2-12 to 4-12 mo juvenilecalves in a ranqe environment is very limited

CO1tinued work in the Tea Garden Plot fairly well protected from deer has show~ reasonably good resul ts for only a few coni fer~ ad hardwoods The 100St

promising at present arc Monterey pine coast redwood and varieties of Pinus halepensis (brutia and eldarica) The most promising hardwoods to date are Eucalyptus globulus camaldulensis (2 variants) urnigera and grandis

In the lower Plot near the Yuba River deer and cattle damage al1d some porcupine debarking have greatly reduced the choice of species here The above pines Arizona cypress plus possibly tamarisk aphylla and coast redwood still appear promising

The North Plot after 3 years of trial plantings versus 4 for the other plots shows promising results for only Arizona cypress Eucalyptus grandis from 2 sources and tamarisk aphylla It is too early to rate the remainj~g species over-all survival rates of which are generally low

No fertilizer tablets have been applied to any of these plots because other factors limiting growth and survival appear more Important There was no serious rodent or insect damage noted in any of the 3 plots this past year and irrigation practices have been generally good probably supplying around 3 acre feet per growing season of about 6 months

It is now planned to establish semi-commercial plots of a minimum of 112 acre for each of at least 5 of the most promising species in another area of the Sierra Field Station

Development work continued in the Campbell Field A fall-1980 seeding of a perennia grass-legume pasture mixture on the new irrigated pasture areas was successful except for parts of some fields where irrigation water (surface flow) failed to reach In general the newly-installed irrigation system performed well

The following work was done on or related to the range fertilization study being conducted on the Forbes Flll44 series fields

a Soil samples were taken from each of the 16 fields Analyses will be made for P 5 Ca Mg K and pH

b In cooperation with M B Jones (HFS) field plots were established at eight locations (4 north-facing aspects 4 south-facing) A factorial design was used to compare 4 levels of N (as urea) and 4 levels of P (as low-S concentrated superphosphate) plus an exploratory for several combinations of NPS with two replications at each locati r

c Also in cooperation with M B Jones a greenhouse pot test was set up at the Hopland Field station with rate-element combinations to match those in the field plots using soil collected at the field locations for the eight replications The pots were seeded with a mixture of sub and rose clovers together with soft chess

d M R George and W J Clawson located sites for a grazing utilization study employing 10 x 10 exclosures

e A field-scale experiment with aerial application of nitrogen (as urea) at 0 40 80 and 120 kgha rates (two fields per replication two replications per treatment) is planned for fall 1982 following evaluation of the tests described above and results of a pre-experiment calibration grazing (with steers) beginning February 1982 Roy Hull J G Morris and R E Delmas are cooperators from the Department of Animal Science

6 Progress Report (Progress during report period toward reaching objectives of this research)

Four pairs of 14 acre plots were established during the fall of 1979 The Blue Oak overstory of these paired plots was approximately 0 25 50 and 75 The tree overstory was removed from one set of four plots by February 15 1980 and 12 wire mesh igloo type cages were placed on all plots by December 1980 Cages were located under tree canopy (or former tree canopy) and in the open using a stratified random procedure with proportional allocation

During 1981 three successive clippings were taken from inside the wire cages to determine the total standing crop present on February 21 (early season) April 3 amp 4 (mid-season) and June 2 (late season)

Preliminary Results (1981)

Uncleared plots 25 50 and 75 overstory cover Standing crop at any season did not differ appreciably by overstory level (Fig 1) When compared with uncleared open (0 overstory cover) plots standing crop was significantly less in uncleared plots at late season but not at early and mid-season Overstory cover and standing crop are not significantly correlated for any season (Fig 2)

Cleared Plots 25 50 and 75 prior overstory cover Standing crop is positively correlated with prior overstory cover particularly when uncleared open (0 overstory cover) plots are included in the comparison (Fig 2)

Tree removal greatly increased standing crop at all three seasons of harvest for all overstory cover levels (Fig 1) When compared to uncleared plots of the same overstory cover level these increases were 100 early season 133 midshyseason and 80 late season

6 Progress Report (Progress during report period toward reaching objectives of this research)

This experiment was undertaken to assess the efficacy and safety of a salt selenium mixture for supplementing range cows

Approximately a years data have been obtained on two groups each of 19 mature Hereford cows grazing range and offered two salt-selenium mineral mixtures free choice The concentration of selenium in one mixture was 40 ppm (low Se group) and the other 80 ppm (high Se group) These levels represent 2 and 4 times the maximal level currently permitted by FDA

Blood selenium concentrations (Figure 1) were determined on each animal at weekly intervals initially then at monthy intervals Intake of the salt-selenium mixture was also measured at monthly intervals to obtain total group mean intake of selenium

Blood selenium concentration rose from the initial concentration of 0035 ~gml to a maxima of approximately 0225 ~gm1 in the high group and 0150 ~gm1 in the low group at about 12 weeks Then maximal concentrations are within the range of normality and in no way indicate selenium toxicity

Intake of the salt-selenium mixture was not well correlated with blood concentration of se1eniUffl

Then data indicate that the FDA maximal level of 20 ppm selenium in salt supplements is conservative and may be ineffectual in areas of selenium deficiency There was no significant difference in the weight of the cows at the time the calves were weaned - low group 487 ~ 48 kg high group - 481 ~ 57 kg

SlJotMARY OF COMMENTS

The foothills of California offer an ideal place for people

to pursue farming Farming in the tradi tional sense family cerltered

labor interlsive small machinery oriented conservation minded small

Hopefully the U C Sierra Foothill Range Field Station will accept

and meet the challenge of providing research and information appropriate

to the fledgling development of a foothill agriculture ethic in which

the quality of food and living is paramount Projects of this nature

are few in the 1981 annual report Possibly we can make II greeter

contribution to foothill farming in the future

Also included in Table 2 are the results for Face fly control following Ectiban tape applications on September 2 Excellent (Group 2) to good (Group 3) control resulted one day after application with tapes applied to ear tags but control did not persist at a satisfactory level as evidenced by the increase in fly counts on September 9 there was poor control via tapes attached to the tail (Group 1) The poor significance of these results are shown in Table 4 Poor results were obtained on face fly ~ontrol upon retreatment of Groups 41 and 50n September 30 and similar JesuIts were evident on Group 6 which was resprayed wi th Co_opertlt~

Of interest in this trial were the results on Horn fly control from the small amount of Ectiban Pour-On to the face of animals Heretofore it was believed that a similar dose of a pesticide to the withers was more effective but if Face fly populations are the main target then face and head applications could serve a dual purpose to include Horn fly control

Early IrrIgation - Liquid Supplement Trial

RIck Delmas

This study was initiated In 1980 to study the performance of

cattle using liquid supplement and the effect of early irrigation of

annual grasslands for early fall growth on the performance of cattle

during the fall and winter grazing period

Though the trial needs to be continued for the next couple of

years the following are indicated from one years data

1) Early irrigation furnishes valuable early fall feed especially

in poor rainfall years

2) Liquid supplement doesnt appear to be as beneficial as concentrates

for young cattle during the fall and winter The conception rate

on cattle with only liquid supplement was 8 to 19 lower than on

the other three treatments Economically the liquid supplement

was half the cost or less of the concentrate excluding labor

From this sfandpoint alone a rancher may be wIlling to accept

a slightly lower conception rate to obtain the decreased labor

and supplement cost Each individual rancher must measure cost

versus production

EFFECT OF OAK TREE REMOVAL ON FORAGE PRODUCTION

1981 was the sixteenth year that forage production has been measured in this study I have considered terminating the measurements because yield increases have not been significant in three of the last four years (see table) However data show that increases were significant in all of the sixteen years in which forage production on the check treatment (area covered by live trees) was below the median of the period (1385 Ibacre) Therefore in the interest of economy only the check treatments will be sampled in high rainfall years If another poor feed year occurs soon we will measure all treatments

6 Progress Report (Progress uring report perio toward reaching objectives of this research) The Ecologv and Population Dynamics of Aphodius fimetarius

The ecological study of the dung beetle Aphodius fimetarius was continued by again monitoring the ability of males and females to hibshyernate (aestivate) from late Spring to Fall From May 29 through June 9 we collected and marked 3020 beetles with fluorescent dust Half of these were released into a beetle-proof screened field cage in the Scott 14 pasture and the other half were released into a s~milar cage at the Howarth pasture o Both cages enclosed about 30 ft of natural turf and each was supplied with fresh dung (beetle food) until no beetles were present These two cages were monitored for the re-eppearance of beetles from September through December and cattle droppings from various pastures were sampled for the presence of naturally appearing wild beetles

During the past year the first beetles appeared in pasture droppings on November 4 when the dung peds had an average of 27 beetlespad On different weeks from November 11 through December 11 the density of ~ fimetarius remained fairly stable at 29 21 23 end 25 beetlespad As in previous years the beetle density then began to decline with 15pad on December 15 and less than one per pad on January 7 1982 In the Fall of 1981 beetles that had been marked and released into the experimental cages first appeared in the Scott 14 pasture on November 9 5 days after beetles first appeared in cattle dung pads in pastures The marked beetles contshyinued to appear in the Scott 14 cage through December with one beetle last appearing on December 16 No beetles were recovered in the Howarth pasture cage and through December 16 only 1 of marked beetles had been recovered in the Scott 14 cage This is in marked contrast to the cage recapture rates of 57 in the Scott pasture and 104 in the Howarth pasture It appears that beetles marked with the fluorescent dust suffershyed heavy mortality most of the marked beetles recovered had only a few particles of dust under the elytra or under the membraneous wings Nevertheless recapture of marked beetles confirmed that ~ fimetarius naturally hibernates (aestivates) in the ground for about 5 months in this part of California Other methods of marking beetles will be tested during the next seaSon

An evaluation was undertaken of the necessity for vitamin A supplementation of range cows

A group of 12 cows were grazed on range without access to irrigated pasture or B carotene supplements At monthly intervals over the past year liver biopsies were performed and blood collected for carotene and vitamin A determinations

At no time did circulating vitamin A concentrations indicate that supplementation was necessary

The relationship between hepatic reserves and circulating levels is being examined

The objectives of this research were outlined in the 1980 report Many of the same trends observed in 1980 were repeated in 1981 Body weights of the cows were positively related to level of supplementation

(Table 1) The greatest effect was observed at the start of the breeding season where the difference between the unsupplemented and 25 times supplemented cows was nearly 100 kg

Weaning weight of the calves (Table 2) reflected the plane of nutrition of the cows Although weaning weights were enhanced by supplementation the largest differences in body weights occurred at the times the dams were mated Body weights of the calves reflected differential milk production of the cows

As in the previous year birth weight of the calves was not affected by plane of nutrition of the cows

6 Progress Report (Progress during report period toward reaching objectives of this research)

The major objectives of this research with Hereford cattle are (1) to determine if individual differences in mounting frequency by juvenile males correlate with individual differences in sexual motivation and performance as adults (2) to determine the degree of correlation between sexual behaviors and other biological traits (eg aggressive behavior semen characteristics hormone levels body size scrotal circumference) (3) to determine the function of mounting exshyperience on the development of sexual behavior and (4) to determine the role of penile stimulation on the development of sexual behavior

Over the last 4 years 78 bulls have been obtained from the SFRFS herd to investigate these questions Twenty-four male calves were brought to Davis from SFRFS in May 1981 to be used in studying objective 114 No observations were made on this group at the Field Station

Prior to 1981 all of our observations on juvenile mounting (Objectives 1 and 3) were made in confined situations where estrous heifers were provided as mountingstimuli and inter-animal contacts were frequent To determine the frequency of juvenile mounting in a more typical range environment 10 male and 9 female purebredHereford calves were observed between January 13 and March 22 1981 for a total of 40 hrs (29 different days) The calves ranged in age from 48 to 102 days (x = 80 days) at the start of observation A total of 394 calf observation hours were made on the 10 bull calves in the group and 749 calf hours on all 19 calves

Relative to our studies in confinement the rate of juvenile mounting in a typical range environment is very low A total of 15 mount intentions 12 mount attempts and 6 mounts (33 mount responses) were observed during the 40 hrs of observation Except for one mount intention all of the mounting activities were exhibited by bull calves The rate of mount responses was 0084 per bull calf per hour of observation Nearly all of the mounting behaviors were observed near the feed trough following feeding of supplements Supplemental feeding was terminated on February 25th and no sexual activity was observed among calves after that date

It was concluded that the mounting experience of 2-12 to 4-12 mo juvenilecalves in a ranqe environment is very limited

In the lower Plot near the Yuba River deer and cattle damage al1d some porcupine debarking have greatly reduced the choice of species here The above pines Arizona cypress plus possibly tamarisk aphylla and coast redwood still appear promising

The North Plot after 3 years of trial plantings versus 4 for the other plots shows promising results for only Arizona cypress Eucalyptus grandis from 2 sources and tamarisk aphylla It is too early to rate the remainj~g species over-all survival rates of which are generally low

No fertilizer tablets have been applied to any of these plots because other factors limiting growth and survival appear more Important There was no serious rodent or insect damage noted in any of the 3 plots this past year and irrigation practices have been generally good probably supplying around 3 acre feet per growing season of about 6 months

It is now planned to establish semi-commercial plots of a minimum of 112 acre for each of at least 5 of the most promising species in another area of the Sierra Field Station

Development work continued in the Campbell Field A fall-1980 seeding of a perennia grass-legume pasture mixture on the new irrigated pasture areas was successful except for parts of some fields where irrigation water (surface flow) failed to reach In general the newly-installed irrigation system performed well

The following work was done on or related to the range fertilization study being conducted on the Forbes Flll44 series fields

a Soil samples were taken from each of the 16 fields Analyses will be made for P 5 Ca Mg K and pH

b In cooperation with M B Jones (HFS) field plots were established at eight locations (4 north-facing aspects 4 south-facing) A factorial design was used to compare 4 levels of N (as urea) and 4 levels of P (as low-S concentrated superphosphate) plus an exploratory for several combinations of NPS with two replications at each locati r

c Also in cooperation with M B Jones a greenhouse pot test was set up at the Hopland Field station with rate-element combinations to match those in the field plots using soil collected at the field locations for the eight replications The pots were seeded with a mixture of sub and rose clovers together with soft chess

d M R George and W J Clawson located sites for a grazing utilization study employing 10 x 10 exclosures

6 Progress Report (Progress during report period toward reaching objectives of this research)

Four pairs of 14 acre plots were established during the fall of 1979 The Blue Oak overstory of these paired plots was approximately 0 25 50 and 75 The tree overstory was removed from one set of four plots by February 15 1980 and 12 wire mesh igloo type cages were placed on all plots by December 1980 Cages were located under tree canopy (or former tree canopy) and in the open using a stratified random procedure with proportional allocation

During 1981 three successive clippings were taken from inside the wire cages to determine the total standing crop present on February 21 (early season) April 3 amp 4 (mid-season) and June 2 (late season)

Preliminary Results (1981)

Uncleared plots 25 50 and 75 overstory cover Standing crop at any season did not differ appreciably by overstory level (Fig 1) When compared with uncleared open (0 overstory cover) plots standing crop was significantly less in uncleared plots at late season but not at early and mid-season Overstory cover and standing crop are not significantly correlated for any season (Fig 2)

Cleared Plots 25 50 and 75 prior overstory cover Standing crop is positively correlated with prior overstory cover particularly when uncleared open (0 overstory cover) plots are included in the comparison (Fig 2)

Tree removal greatly increased standing crop at all three seasons of harvest for all overstory cover levels (Fig 1) When compared to uncleared plots of the same overstory cover level these increases were 100 early season 133 midshyseason and 80 late season

6 Progress Report (Progress during report period toward reaching objectives of this research)

This experiment was undertaken to assess the efficacy and safety of a salt selenium mixture for supplementing range cows

Approximately a years data have been obtained on two groups each of 19 mature Hereford cows grazing range and offered two salt-selenium mineral mixtures free choice The concentration of selenium in one mixture was 40 ppm (low Se group) and the other 80 ppm (high Se group) These levels represent 2 and 4 times the maximal level currently permitted by FDA

Blood selenium concentrations (Figure 1) were determined on each animal at weekly intervals initially then at monthy intervals Intake of the salt-selenium mixture was also measured at monthly intervals to obtain total group mean intake of selenium

Blood selenium concentration rose from the initial concentration of 0035 ~gml to a maxima of approximately 0225 ~gm1 in the high group and 0150 ~gm1 in the low group at about 12 weeks Then maximal concentrations are within the range of normality and in no way indicate selenium toxicity

Intake of the salt-selenium mixture was not well correlated with blood concentration of se1eniUffl

Then data indicate that the FDA maximal level of 20 ppm selenium in salt supplements is conservative and may be ineffectual in areas of selenium deficiency There was no significant difference in the weight of the cows at the time the calves were weaned - low group 487 ~ 48 kg high group - 481 ~ 57 kg

The foothills of California offer an ideal place for people

to pursue farming Farming in the tradi tional sense family cerltered

labor interlsive small machinery oriented conservation minded small

Hopefully the U C Sierra Foothill Range Field Station will accept

and meet the challenge of providing research and information appropriate

to the fledgling development of a foothill agriculture ethic in which

the quality of food and living is paramount Projects of this nature

are few in the 1981 annual report Possibly we can make II greeter

contribution to foothill farming in the future

Early IrrIgation - Liquid Supplement Trial

RIck Delmas

This study was initiated In 1980 to study the performance of

cattle using liquid supplement and the effect of early irrigation of

annual grasslands for early fall growth on the performance of cattle

during the fall and winter grazing period

Though the trial needs to be continued for the next couple of

years the following are indicated from one years data

1) Early irrigation furnishes valuable early fall feed especially

in poor rainfall years

2) Liquid supplement doesnt appear to be as beneficial as concentrates

for young cattle during the fall and winter The conception rate

on cattle with only liquid supplement was 8 to 19 lower than on

the other three treatments Economically the liquid supplement

was half the cost or less of the concentrate excluding labor

From this sfandpoint alone a rancher may be wIlling to accept

a slightly lower conception rate to obtain the decreased labor

and supplement cost Each individual rancher must measure cost

versus production

EFFECT OF OAK TREE REMOVAL ON FORAGE PRODUCTION

1981 was the sixteenth year that forage production has been measured in this study I have considered terminating the measurements because yield increases have not been significant in three of the last four years (see table) However data show that increases were significant in all of the sixteen years in which forage production on the check treatment (area covered by live trees) was below the median of the period (1385 Ibacre) Therefore in the interest of economy only the check treatments will be sampled in high rainfall years If another poor feed year occurs soon we will measure all treatments

6 Progress Report (Progress uring report perio toward reaching objectives of this research) The Ecologv and Population Dynamics of Aphodius fimetarius

The ecological study of the dung beetle Aphodius fimetarius was continued by again monitoring the ability of males and females to hibshyernate (aestivate) from late Spring to Fall From May 29 through June 9 we collected and marked 3020 beetles with fluorescent dust Half of these were released into a beetle-proof screened field cage in the Scott 14 pasture and the other half were released into a s~milar cage at the Howarth pasture o Both cages enclosed about 30 ft of natural turf and each was supplied with fresh dung (beetle food) until no beetles were present These two cages were monitored for the re-eppearance of beetles from September through December and cattle droppings from various pastures were sampled for the presence of naturally appearing wild beetles

During the past year the first beetles appeared in pasture droppings on November 4 when the dung peds had an average of 27 beetlespad On different weeks from November 11 through December 11 the density of ~ fimetarius remained fairly stable at 29 21 23 end 25 beetlespad As in previous years the beetle density then began to decline with 15pad on December 15 and less than one per pad on January 7 1982 In the Fall of 1981 beetles that had been marked and released into the experimental cages first appeared in the Scott 14 pasture on November 9 5 days after beetles first appeared in cattle dung pads in pastures The marked beetles contshyinued to appear in the Scott 14 cage through December with one beetle last appearing on December 16 No beetles were recovered in the Howarth pasture cage and through December 16 only 1 of marked beetles had been recovered in the Scott 14 cage This is in marked contrast to the cage recapture rates of 57 in the Scott pasture and 104 in the Howarth pasture It appears that beetles marked with the fluorescent dust suffershyed heavy mortality most of the marked beetles recovered had only a few particles of dust under the elytra or under the membraneous wings Nevertheless recapture of marked beetles confirmed that ~ fimetarius naturally hibernates (aestivates) in the ground for about 5 months in this part of California Other methods of marking beetles will be tested during the next seaSon

The objectives of this research were outlined in the 1980 report Many of the same trends observed in 1980 were repeated in 1981 Body weights of the cows were positively related to level of supplementation

(Table 1) The greatest effect was observed at the start of the breeding season where the difference between the unsupplemented and 25 times supplemented cows was nearly 100 kg

Weaning weight of the calves (Table 2) reflected the plane of nutrition of the cows Although weaning weights were enhanced by supplementation the largest differences in body weights occurred at the times the dams were mated Body weights of the calves reflected differential milk production of the cows

As in the previous year birth weight of the calves was not affected by plane of nutrition of the cows

6 Progress Report (Progress during report period toward reaching objectives of this research)

The major objectives of this research with Hereford cattle are (1) to determine if individual differences in mounting frequency by juvenile males correlate with individual differences in sexual motivation and performance as adults (2) to determine the degree of correlation between sexual behaviors and other biological traits (eg aggressive behavior semen characteristics hormone levels body size scrotal circumference) (3) to determine the function of mounting exshyperience on the development of sexual behavior and (4) to determine the role of penile stimulation on the development of sexual behavior

Over the last 4 years 78 bulls have been obtained from the SFRFS herd to investigate these questions Twenty-four male calves were brought to Davis from SFRFS in May 1981 to be used in studying objective 114 No observations were made on this group at the Field Station

Prior to 1981 all of our observations on juvenile mounting (Objectives 1 and 3) were made in confined situations where estrous heifers were provided as mountingstimuli and inter-animal contacts were frequent To determine the frequency of juvenile mounting in a more typical range environment 10 male and 9 female purebredHereford calves were observed between January 13 and March 22 1981 for a total of 40 hrs (29 different days) The calves ranged in age from 48 to 102 days (x = 80 days) at the start of observation A total of 394 calf observation hours were made on the 10 bull calves in the group and 749 calf hours on all 19 calves

Relative to our studies in confinement the rate of juvenile mounting in a typical range environment is very low A total of 15 mount intentions 12 mount attempts and 6 mounts (33 mount responses) were observed during the 40 hrs of observation Except for one mount intention all of the mounting activities were exhibited by bull calves The rate of mount responses was 0084 per bull calf per hour of observation Nearly all of the mounting behaviors were observed near the feed trough following feeding of supplements Supplemental feeding was terminated on February 25th and no sexual activity was observed among calves after that date

It was concluded that the mounting experience of 2-12 to 4-12 mo juvenilecalves in a ranqe environment is very limited

promising at present arc Monterey pine coast redwood and varieties of Pinus halepensis (brutia and eldarica) The most promising hardwoods to date are Eucalyptus globulus camaldulensis (2 variants) urnigera and grandis

In the lower Plot near the Yuba River deer and cattle damage al1d some porcupine debarking have greatly reduced the choice of species here The above pines Arizona cypress plus possibly tamarisk aphylla and coast redwood still appear promising

The North Plot after 3 years of trial plantings versus 4 for the other plots shows promising results for only Arizona cypress Eucalyptus grandis from 2 sources and tamarisk aphylla It is too early to rate the remainj~g species over-all survival rates of which are generally low

No fertilizer tablets have been applied to any of these plots because other factors limiting growth and survival appear more Important There was no serious rodent or insect damage noted in any of the 3 plots this past year and irrigation practices have been generally good probably supplying around 3 acre feet per growing season of about 6 months

It is now planned to establish semi-commercial plots of a minimum of 112 acre for each of at least 5 of the most promising species in another area of the Sierra Field Station

Development work continued in the Campbell Field A fall-1980 seeding of a perennia grass-legume pasture mixture on the new irrigated pasture areas was successful except for parts of some fields where irrigation water (surface flow) failed to reach In general the newly-installed irrigation system performed well

The following work was done on or related to the range fertilization study being conducted on the Forbes Flll44 series fields

a Soil samples were taken from each of the 16 fields Analyses will be made for P 5 Ca Mg K and pH

b In cooperation with M B Jones (HFS) field plots were established at eight locations (4 north-facing aspects 4 south-facing) A factorial design was used to compare 4 levels of N (as urea) and 4 levels of P (as low-S concentrated superphosphate) plus an exploratory for several combinations of NPS with two replications at each locati r

c Also in cooperation with M B Jones a greenhouse pot test was set up at the Hopland Field station with rate-element combinations to match those in the field plots using soil collected at the field locations for the eight replications The pots were seeded with a mixture of sub and rose clovers together with soft chess

d M R George and W J Clawson located sites for a grazing utilization study employing 10 x 10 exclosures

e A field-scale experiment with aerial application of nitrogen (as urea) at 0 40 80 and 120 kgha rates (two fields per replication two replications per treatment) is planned for fall 1982 following evaluation of the tests described above and results of a pre-experiment calibration grazing (with steers) beginning February 1982 Roy Hull J G Morris and R E Delmas are cooperators from the Department of Animal Science

6 Progress Report (Progress during report period toward reaching objectives of this research)

Four pairs of 14 acre plots were established during the fall of 1979 The Blue Oak overstory of these paired plots was approximately 0 25 50 and 75 The tree overstory was removed from one set of four plots by February 15 1980 and 12 wire mesh igloo type cages were placed on all plots by December 1980 Cages were located under tree canopy (or former tree canopy) and in the open using a stratified random procedure with proportional allocation

During 1981 three successive clippings were taken from inside the wire cages to determine the total standing crop present on February 21 (early season) April 3 amp 4 (mid-season) and June 2 (late season)

Preliminary Results (1981)

Uncleared plots 25 50 and 75 overstory cover Standing crop at any season did not differ appreciably by overstory level (Fig 1) When compared with uncleared open (0 overstory cover) plots standing crop was significantly less in uncleared plots at late season but not at early and mid-season Overstory cover and standing crop are not significantly correlated for any season (Fig 2)

Cleared Plots 25 50 and 75 prior overstory cover Standing crop is positively correlated with prior overstory cover particularly when uncleared open (0 overstory cover) plots are included in the comparison (Fig 2)

Tree removal greatly increased standing crop at all three seasons of harvest for all overstory cover levels (Fig 1) When compared to uncleared plots of the same overstory cover level these increases were 100 early season 133 midshyseason and 80 late season

6 Progress Report (Progress during report perlod toward reaching objectives of this research)

The major objective of this study is to determine differences in the maternal care provided tw1n calves relative to the maternal behavior of cows with singleoffspring when placed 1n a range environment Observations were conducted duringJanuary February and March 1981 at SFRFS on 7 cows with single calves and 5 cows with twins housed in a 75A pasture The animals were observed for 15 hrs per week during the f1rst two hrs following sunrise and the two hrs preceding sunset

Data collected on mothers included frequency and duration of licking (grooming) calves vocalizattons butts and butt attempts directed at alien calves and behavioral responses to separatton from calf(ves) Calves were observed for frequency and duration of sucking on own and aUen mothers frequency and duration of resting runn1ng laying and grazing frequency of vocalizations and juvenilemounting and prox1m1ty to mother tw1n and nea~est unrelated calf

The data have been compiled but have not yet been analyzed statistically

Efficacy of sall as a vehicle for selenium supplementatio~

4 Project Leader J G Morri 5 1 5 bull Period Covered QL sectL - 1L A by this Report mo yr mo yr

6 Progress Report (Progress during report period toward reaching objectives of this research)

This experiment was undertaken to assess the efficacy and safety of a salt selenium mixture for supplementing range cows

Approximately a years data have been obtained on two groups each of 19 mature Hereford cows grazing range and offered two salt-selenium mineral mixtures free choice The concentration of selenium in one mixture was 40 ppm (low Se group) and the other 80 ppm (high Se group) These levels represent 2 and 4 times the maximal level currently permitted by FDA

Blood selenium concentrations (Figure 1) were determined on each animal at weekly intervals initially then at monthy intervals Intake of the salt-selenium mixture was also measured at monthly intervals to obtain total group mean intake of selenium

Blood selenium concentration rose from the initial concentration of 0035 ~gml to a maxima of approximately 0225 ~gm1 in the high group and 0150 ~gm1 in the low group at about 12 weeks Then maximal concentrations are within the range of normality and in no way indicate selenium toxicity

Intake of the salt-selenium mixture was not well correlated with blood concentration of se1eniUffl

Then data indicate that the FDA maximal level of 20 ppm selenium in salt supplements is conservative and may be ineffectual in areas of selenium deficiency There was no significant difference in the weight of the cows at the time the calves were weaned - low group 487 ~ 48 kg high group - 481 ~ 57 kg

SlJotMARY OF COMMENTS

The foothills of California offer an ideal place for people

to pursue farming Farming in the tradi tional sense family cerltered

labor interlsive small machinery oriented conservation minded small

Hopefully the U C Sierra Foothill Range Field Station will accept

and meet the challenge of providing research and information appropriate

to the fledgling development of a foothill agriculture ethic in which

the quality of food and living is paramount Projects of this nature

are few in the 1981 annual report Possibly we can make II greeter

contribution to foothill farming in the future

Early IrrIgation - Liquid Supplement Trial

RIck Delmas

This study was initiated In 1980 to study the performance of

cattle using liquid supplement and the effect of early irrigation of

annual grasslands for early fall growth on the performance of cattle

during the fall and winter grazing period

Though the trial needs to be continued for the next couple of

years the following are indicated from one years data

1) Early irrigation furnishes valuable early fall feed especially

in poor rainfall years

2) Liquid supplement doesnt appear to be as beneficial as concentrates

for young cattle during the fall and winter The conception rate

on cattle with only liquid supplement was 8 to 19 lower than on

the other three treatments Economically the liquid supplement

was half the cost or less of the concentrate excluding labor

From this sfandpoint alone a rancher may be wIlling to accept

a slightly lower conception rate to obtain the decreased labor

and supplement cost Each individual rancher must measure cost

versus production

EFFECT OF OAK TREE REMOVAL ON FORAGE PRODUCTION

1981 was the sixteenth year that forage production has been measured in this study I have considered terminating the measurements because yield increases have not been significant in three of the last four years (see table) However data show that increases were significant in all of the sixteen years in which forage production on the check treatment (area covered by live trees) was below the median of the period (1385 Ibacre) Therefore in the interest of economy only the check treatments will be sampled in high rainfall years If another poor feed year occurs soon we will measure all treatments

6 Progress Report (Progress uring report perio toward reaching objectives of this research) The Ecologv and Population Dynamics of Aphodius fimetarius

The ecological study of the dung beetle Aphodius fimetarius was continued by again monitoring the ability of males and females to hibshyernate (aestivate) from late Spring to Fall From May 29 through June 9 we collected and marked 3020 beetles with fluorescent dust Half of these were released into a beetle-proof screened field cage in the Scott 14 pasture and the other half were released into a s~milar cage at the Howarth pasture o Both cages enclosed about 30 ft of natural turf and each was supplied with fresh dung (beetle food) until no beetles were present These two cages were monitored for the re-eppearance of beetles from September through December and cattle droppings from various pastures were sampled for the presence of naturally appearing wild beetles

During the past year the first beetles appeared in pasture droppings on November 4 when the dung peds had an average of 27 beetlespad On different weeks from November 11 through December 11 the density of ~ fimetarius remained fairly stable at 29 21 23 end 25 beetlespad As in previous years the beetle density then began to decline with 15pad on December 15 and less than one per pad on January 7 1982 In the Fall of 1981 beetles that had been marked and released into the experimental cages first appeared in the Scott 14 pasture on November 9 5 days after beetles first appeared in cattle dung pads in pastures The marked beetles contshyinued to appear in the Scott 14 cage through December with one beetle last appearing on December 16 No beetles were recovered in the Howarth pasture cage and through December 16 only 1 of marked beetles had been recovered in the Scott 14 cage This is in marked contrast to the cage recapture rates of 57 in the Scott pasture and 104 in the Howarth pasture It appears that beetles marked with the fluorescent dust suffershyed heavy mortality most of the marked beetles recovered had only a few particles of dust under the elytra or under the membraneous wings Nevertheless recapture of marked beetles confirmed that ~ fimetarius naturally hibernates (aestivates) in the ground for about 5 months in this part of California Other methods of marking beetles will be tested during the next seaSon

The objectives of this research were outlined in the 1980 report Many of the same trends observed in 1980 were repeated in 1981 Body weights of the cows were positively related to level of supplementation

(Table 1) The greatest effect was observed at the start of the breeding season where the difference between the unsupplemented and 25 times supplemented cows was nearly 100 kg

Weaning weight of the calves (Table 2) reflected the plane of nutrition of the cows Although weaning weights were enhanced by supplementation the largest differences in body weights occurred at the times the dams were mated Body weights of the calves reflected differential milk production of the cows

As in the previous year birth weight of the calves was not affected by plane of nutrition of the cows

6 Progress Report (Progress during report period toward reaching objectives of this research)

The major objectives of this research with Hereford cattle are (1) to determine if individual differences in mounting frequency by juvenile males correlate with individual differences in sexual motivation and performance as adults (2) to determine the degree of correlation between sexual behaviors and other biological traits (eg aggressive behavior semen characteristics hormone levels body size scrotal circumference) (3) to determine the function of mounting exshyperience on the development of sexual behavior and (4) to determine the role of penile stimulation on the development of sexual behavior

Over the last 4 years 78 bulls have been obtained from the SFRFS herd to investigate these questions Twenty-four male calves were brought to Davis from SFRFS in May 1981 to be used in studying objective 114 No observations were made on this group at the Field Station

Prior to 1981 all of our observations on juvenile mounting (Objectives 1 and 3) were made in confined situations where estrous heifers were provided as mountingstimuli and inter-animal contacts were frequent To determine the frequency of juvenile mounting in a more typical range environment 10 male and 9 female purebredHereford calves were observed between January 13 and March 22 1981 for a total of 40 hrs (29 different days) The calves ranged in age from 48 to 102 days (x = 80 days) at the start of observation A total of 394 calf observation hours were made on the 10 bull calves in the group and 749 calf hours on all 19 calves

Relative to our studies in confinement the rate of juvenile mounting in a typical range environment is very low A total of 15 mount intentions 12 mount attempts and 6 mounts (33 mount responses) were observed during the 40 hrs of observation Except for one mount intention all of the mounting activities were exhibited by bull calves The rate of mount responses was 0084 per bull calf per hour of observation Nearly all of the mounting behaviors were observed near the feed trough following feeding of supplements Supplemental feeding was terminated on February 25th and no sexual activity was observed among calves after that date

It was concluded that the mounting experience of 2-12 to 4-12 mo juvenilecalves in a ranqe environment is very limited

promising at present arc Monterey pine coast redwood and varieties of Pinus halepensis (brutia and eldarica) The most promising hardwoods to date are Eucalyptus globulus camaldulensis (2 variants) urnigera and grandis

In the lower Plot near the Yuba River deer and cattle damage al1d some porcupine debarking have greatly reduced the choice of species here The above pines Arizona cypress plus possibly tamarisk aphylla and coast redwood still appear promising

The North Plot after 3 years of trial plantings versus 4 for the other plots shows promising results for only Arizona cypress Eucalyptus grandis from 2 sources and tamarisk aphylla It is too early to rate the remainj~g species over-all survival rates of which are generally low

No fertilizer tablets have been applied to any of these plots because other factors limiting growth and survival appear more Important There was no serious rodent or insect damage noted in any of the 3 plots this past year and irrigation practices have been generally good probably supplying around 3 acre feet per growing season of about 6 months

It is now planned to establish semi-commercial plots of a minimum of 112 acre for each of at least 5 of the most promising species in another area of the Sierra Field Station

Development work continued in the Campbell Field A fall-1980 seeding of a perennia grass-legume pasture mixture on the new irrigated pasture areas was successful except for parts of some fields where irrigation water (surface flow) failed to reach In general the newly-installed irrigation system performed well

The following work was done on or related to the range fertilization study being conducted on the Forbes Flll44 series fields

a Soil samples were taken from each of the 16 fields Analyses will be made for P 5 Ca Mg K and pH

b In cooperation with M B Jones (HFS) field plots were established at eight locations (4 north-facing aspects 4 south-facing) A factorial design was used to compare 4 levels of N (as urea) and 4 levels of P (as low-S concentrated superphosphate) plus an exploratory for several combinations of NPS with two replications at each locati r

c Also in cooperation with M B Jones a greenhouse pot test was set up at the Hopland Field station with rate-element combinations to match those in the field plots using soil collected at the field locations for the eight replications The pots were seeded with a mixture of sub and rose clovers together with soft chess

d M R George and W J Clawson located sites for a grazing utilization study employing 10 x 10 exclosures

e A field-scale experiment with aerial application of nitrogen (as urea) at 0 40 80 and 120 kgha rates (two fields per replication two replications per treatment) is planned for fall 1982 following evaluation of the tests described above and results of a pre-experiment calibration grazing (with steers) beginning February 1982 Roy Hull J G Morris and R E Delmas are cooperators from the Department of Animal Science

During 1981 three successive clippings were taken from inside the wire cages to determine the total standing crop present on February 21 (early season) April 3 amp 4 (mid-season) and June 2 (late season)

Preliminary Results (1981)

Uncleared plots 25 50 and 75 overstory cover Standing crop at any season did not differ appreciably by overstory level (Fig 1) When compared with uncleared open (0 overstory cover) plots standing crop was significantly less in uncleared plots at late season but not at early and mid-season Overstory cover and standing crop are not significantly correlated for any season (Fig 2)

Cleared Plots 25 50 and 75 prior overstory cover Standing crop is positively correlated with prior overstory cover particularly when uncleared open (0 overstory cover) plots are included in the comparison (Fig 2)

Tree removal greatly increased standing crop at all three seasons of harvest for all overstory cover levels (Fig 1) When compared to uncleared plots of the same overstory cover level these increases were 100 early season 133 midshyseason and 80 late season

During the first phase of the trial we are observing tropical plants Varieties were I isted in last year1s report The Leucaena species was eliminated Last winter was a relatively mild winter thus we feel we did not obtain good cold readings on the other species Further observations will be made this coming year

In the second phase we have planted species and varieties of Orchardgrass Tall Fescue and Perennial Ryegrass from the Georgia Plant Station In addition planted species of the same plants used in California irrigated pastures Stand evaluations were made on all species this past year only This coming year we will obtain yield data

The major objective of this study is to determine differences in the maternal care provided tw1n calves relative to the maternal behavior of cows with singleoffspring when placed 1n a range environment Observations were conducted duringJanuary February and March 1981 at SFRFS on 7 cows with single calves and 5 cows with twins housed in a 75A pasture The animals were observed for 15 hrs per week during the f1rst two hrs following sunrise and the two hrs preceding sunset

Data collected on mothers included frequency and duration of licking (grooming) calves vocalizattons butts and butt attempts directed at alien calves and behavioral responses to separatton from calf(ves) Calves were observed for frequency and duration of sucking on own and aUen mothers frequency and duration of resting runn1ng laying and grazing frequency of vocalizations and juvenilemounting and prox1m1ty to mother tw1n and nea~est unrelated calf

The data have been compiled but have not yet been analyzed statistically

Efficacy of sall as a vehicle for selenium supplementatio~

6 Progress Report (Progress during report period toward reaching objectives of this research)

This experiment was undertaken to assess the efficacy and safety of a salt selenium mixture for supplementing range cows

Approximately a years data have been obtained on two groups each of 19 mature Hereford cows grazing range and offered two salt-selenium mineral mixtures free choice The concentration of selenium in one mixture was 40 ppm (low Se group) and the other 80 ppm (high Se group) These levels represent 2 and 4 times the maximal level currently permitted by FDA

Blood selenium concentrations (Figure 1) were determined on each animal at weekly intervals initially then at monthy intervals Intake of the salt-selenium mixture was also measured at monthly intervals to obtain total group mean intake of selenium

Blood selenium concentration rose from the initial concentration of 0035 ~gml to a maxima of approximately 0225 ~gm1 in the high group and 0150 ~gm1 in the low group at about 12 weeks Then maximal concentrations are within the range of normality and in no way indicate selenium toxicity

Intake of the salt-selenium mixture was not well correlated with blood concentration of se1eniUffl

Then data indicate that the FDA maximal level of 20 ppm selenium in salt supplements is conservative and may be ineffectual in areas of selenium deficiency There was no significant difference in the weight of the cows at the time the calves were weaned - low group 487 ~ 48 kg high group - 481 ~ 57 kg

SlJotMARY OF COMMENTS

The foothills of California offer an ideal place for people

to pursue farming Farming in the tradi tional sense family cerltered

labor interlsive small machinery oriented conservation minded small

Hopefully the U C Sierra Foothill Range Field Station will accept

and meet the challenge of providing research and information appropriate

to the fledgling development of a foothill agriculture ethic in which

the quality of food and living is paramount Projects of this nature

are few in the 1981 annual report Possibly we can make II greeter

contribution to foothill farming in the future

Early IrrIgation - Liquid Supplement Trial

RIck Delmas

This study was initiated In 1980 to study the performance of

cattle using liquid supplement and the effect of early irrigation of

annual grasslands for early fall growth on the performance of cattle

during the fall and winter grazing period

Though the trial needs to be continued for the next couple of

years the following are indicated from one years data

1) Early irrigation furnishes valuable early fall feed especially

in poor rainfall years

2) Liquid supplement doesnt appear to be as beneficial as concentrates

for young cattle during the fall and winter The conception rate

on cattle with only liquid supplement was 8 to 19 lower than on

the other three treatments Economically the liquid supplement

was half the cost or less of the concentrate excluding labor

From this sfandpoint alone a rancher may be wIlling to accept

a slightly lower conception rate to obtain the decreased labor

and supplement cost Each individual rancher must measure cost

versus production

EFFECT OF OAK TREE REMOVAL ON FORAGE PRODUCTION

1981 was the sixteenth year that forage production has been measured in this study I have considered terminating the measurements because yield increases have not been significant in three of the last four years (see table) However data show that increases were significant in all of the sixteen years in which forage production on the check treatment (area covered by live trees) was below the median of the period (1385 Ibacre) Therefore in the interest of economy only the check treatments will be sampled in high rainfall years If another poor feed year occurs soon we will measure all treatments

6 Progress Report (Progress uring report perio toward reaching objectives of this research) The Ecologv and Population Dynamics of Aphodius fimetarius

The ecological study of the dung beetle Aphodius fimetarius was continued by again monitoring the ability of males and females to hibshyernate (aestivate) from late Spring to Fall From May 29 through June 9 we collected and marked 3020 beetles with fluorescent dust Half of these were released into a beetle-proof screened field cage in the Scott 14 pasture and the other half were released into a s~milar cage at the Howarth pasture o Both cages enclosed about 30 ft of natural turf and each was supplied with fresh dung (beetle food) until no beetles were present These two cages were monitored for the re-eppearance of beetles from September through December and cattle droppings from various pastures were sampled for the presence of naturally appearing wild beetles

During the past year the first beetles appeared in pasture droppings on November 4 when the dung peds had an average of 27 beetlespad On different weeks from November 11 through December 11 the density of ~ fimetarius remained fairly stable at 29 21 23 end 25 beetlespad As in previous years the beetle density then began to decline with 15pad on December 15 and less than one per pad on January 7 1982 In the Fall of 1981 beetles that had been marked and released into the experimental cages first appeared in the Scott 14 pasture on November 9 5 days after beetles first appeared in cattle dung pads in pastures The marked beetles contshyinued to appear in the Scott 14 cage through December with one beetle last appearing on December 16 No beetles were recovered in the Howarth pasture cage and through December 16 only 1 of marked beetles had been recovered in the Scott 14 cage This is in marked contrast to the cage recapture rates of 57 in the Scott pasture and 104 in the Howarth pasture It appears that beetles marked with the fluorescent dust suffershyed heavy mortality most of the marked beetles recovered had only a few particles of dust under the elytra or under the membraneous wings Nevertheless recapture of marked beetles confirmed that ~ fimetarius naturally hibernates (aestivates) in the ground for about 5 months in this part of California Other methods of marking beetles will be tested during the next seaSon

The objectives of this research were outlined in the 1980 report Many of the same trends observed in 1980 were repeated in 1981 Body weights of the cows were positively related to level of supplementation

(Table 1) The greatest effect was observed at the start of the breeding season where the difference between the unsupplemented and 25 times supplemented cows was nearly 100 kg

Weaning weight of the calves (Table 2) reflected the plane of nutrition of the cows Although weaning weights were enhanced by supplementation the largest differences in body weights occurred at the times the dams were mated Body weights of the calves reflected differential milk production of the cows

As in the previous year birth weight of the calves was not affected by plane of nutrition of the cows

6 Progress Report (Progress during report period toward reaching objectives of this research)

The major objectives of this research with Hereford cattle are (1) to determine if individual differences in mounting frequency by juvenile males correlate with individual differences in sexual motivation and performance as adults (2) to determine the degree of correlation between sexual behaviors and other biological traits (eg aggressive behavior semen characteristics hormone levels body size scrotal circumference) (3) to determine the function of mounting exshyperience on the development of sexual behavior and (4) to determine the role of penile stimulation on the development of sexual behavior

Over the last 4 years 78 bulls have been obtained from the SFRFS herd to investigate these questions Twenty-four male calves were brought to Davis from SFRFS in May 1981 to be used in studying objective 114 No observations were made on this group at the Field Station

Prior to 1981 all of our observations on juvenile mounting (Objectives 1 and 3) were made in confined situations where estrous heifers were provided as mountingstimuli and inter-animal contacts were frequent To determine the frequency of juvenile mounting in a more typical range environment 10 male and 9 female purebredHereford calves were observed between January 13 and March 22 1981 for a total of 40 hrs (29 different days) The calves ranged in age from 48 to 102 days (x = 80 days) at the start of observation A total of 394 calf observation hours were made on the 10 bull calves in the group and 749 calf hours on all 19 calves

Relative to our studies in confinement the rate of juvenile mounting in a typical range environment is very low A total of 15 mount intentions 12 mount attempts and 6 mounts (33 mount responses) were observed during the 40 hrs of observation Except for one mount intention all of the mounting activities were exhibited by bull calves The rate of mount responses was 0084 per bull calf per hour of observation Nearly all of the mounting behaviors were observed near the feed trough following feeding of supplements Supplemental feeding was terminated on February 25th and no sexual activity was observed among calves after that date

It was concluded that the mounting experience of 2-12 to 4-12 mo juvenilecalves in a ranqe environment is very limited

promising at present arc Monterey pine coast redwood and varieties of Pinus halepensis (brutia and eldarica) The most promising hardwoods to date are Eucalyptus globulus camaldulensis (2 variants) urnigera and grandis

In the lower Plot near the Yuba River deer and cattle damage al1d some porcupine debarking have greatly reduced the choice of species here The above pines Arizona cypress plus possibly tamarisk aphylla and coast redwood still appear promising

The North Plot after 3 years of trial plantings versus 4 for the other plots shows promising results for only Arizona cypress Eucalyptus grandis from 2 sources and tamarisk aphylla It is too early to rate the remainj~g species over-all survival rates of which are generally low

No fertilizer tablets have been applied to any of these plots because other factors limiting growth and survival appear more Important There was no serious rodent or insect damage noted in any of the 3 plots this past year and irrigation practices have been generally good probably supplying around 3 acre feet per growing season of about 6 months

It is now planned to establish semi-commercial plots of a minimum of 112 acre for each of at least 5 of the most promising species in another area of the Sierra Field Station

Development work continued in the Campbell Field A fall-1980 seeding of a perennia grass-legume pasture mixture on the new irrigated pasture areas was successful except for parts of some fields where irrigation water (surface flow) failed to reach In general the newly-installed irrigation system performed well

The following work was done on or related to the range fertilization study being conducted on the Forbes Flll44 series fields

a Soil samples were taken from each of the 16 fields Analyses will be made for P 5 Ca Mg K and pH

b In cooperation with M B Jones (HFS) field plots were established at eight locations (4 north-facing aspects 4 south-facing) A factorial design was used to compare 4 levels of N (as urea) and 4 levels of P (as low-S concentrated superphosphate) plus an exploratory for several combinations of NPS with two replications at each locati r

c Also in cooperation with M B Jones a greenhouse pot test was set up at the Hopland Field station with rate-element combinations to match those in the field plots using soil collected at the field locations for the eight replications The pots were seeded with a mixture of sub and rose clovers together with soft chess

d M R George and W J Clawson located sites for a grazing utilization study employing 10 x 10 exclosures

e A field-scale experiment with aerial application of nitrogen (as urea) at 0 40 80 and 120 kgha rates (two fields per replication two replications per treatment) is planned for fall 1982 following evaluation of the tests described above and results of a pre-experiment calibration grazing (with steers) beginning February 1982 Roy Hull J G Morris and R E Delmas are cooperators from the Department of Animal Science

This is the third year in which numbers of infective parasite larvae on pasture has been assessed by placing 2 worm-free tracer calves on pasture at monthly intervals Since this is only one of several locations where these studies are being conducted not all laboratory analyses have been completedNevertheless studies over the three year period demonstrates the occurrence of infective nematode larvae on pastures is repetitive and predictable The season for the occurrence of disease producing numbers of various species differs little in such diverse regions as the San Joaquin Valley (Elk Grove) the East Slope of the Sierras (Susanville) or the Sierra Foothills (UCSFR) This studycorroborates the newly emerging concepts of safe and unsafe grazing periods The application of data from this study can be utilized in managerial decisions and thus in Integrated Pest (parasite) Control programs It is planned that trials designed to establish the value of these IPC programs will be initiated at several locations including UCSFR during the 1981-82 year

6 Progress Report (Progress during report period toward reaching objectives of this research)

Four pairs of 14 acre plots were established during the fall of 1979 The Blue Oak overstory of these paired plots was approximately 0 25 50 and 75 The tree overstory was removed from one set of four plots by February 15 1980 and 12 wire mesh igloo type cages were placed on all plots by December 1980 Cages were located under tree canopy (or former tree canopy) and in the open using a stratified random procedure with proportional allocation

During 1981 three successive clippings were taken from inside the wire cages to determine the total standing crop present on February 21 (early season) April 3 amp 4 (mid-season) and June 2 (late season)

Preliminary Results (1981)

Uncleared plots 25 50 and 75 overstory cover Standing crop at any season did not differ appreciably by overstory level (Fig 1) When compared with uncleared open (0 overstory cover) plots standing crop was significantly less in uncleared plots at late season but not at early and mid-season Overstory cover and standing crop are not significantly correlated for any season (Fig 2)

Cleared Plots 25 50 and 75 prior overstory cover Standing crop is positively correlated with prior overstory cover particularly when uncleared open (0 overstory cover) plots are included in the comparison (Fig 2)

Tree removal greatly increased standing crop at all three seasons of harvest for all overstory cover levels (Fig 1) When compared to uncleared plots of the same overstory cover level these increases were 100 early season 133 midshyseason and 80 late season

During the first phase of the trial we are observing tropical plants Varieties were I isted in last year1s report The Leucaena species was eliminated Last winter was a relatively mild winter thus we feel we did not obtain good cold readings on the other species Further observations will be made this coming year

In the second phase we have planted species and varieties of Orchardgrass Tall Fescue and Perennial Ryegrass from the Georgia Plant Station In addition planted species of the same plants used in California irrigated pastures Stand evaluations were made on all species this past year only This coming year we will obtain yield data

The major objective of this study is to determine differences in the maternal care provided tw1n calves relative to the maternal behavior of cows with singleoffspring when placed 1n a range environment Observations were conducted duringJanuary February and March 1981 at SFRFS on 7 cows with single calves and 5 cows with twins housed in a 75A pasture The animals were observed for 15 hrs per week during the f1rst two hrs following sunrise and the two hrs preceding sunset

Data collected on mothers included frequency and duration of licking (grooming) calves vocalizattons butts and butt attempts directed at alien calves and behavioral responses to separatton from calf(ves) Calves were observed for frequency and duration of sucking on own and aUen mothers frequency and duration of resting runn1ng laying and grazing frequency of vocalizations and juvenilemounting and prox1m1ty to mother tw1n and nea~est unrelated calf

The data have been compiled but have not yet been analyzed statistically

Efficacy of sall as a vehicle for selenium supplementatio~

6 Progress Report (Progress during report period toward reaching objectives of this research)

This experiment was undertaken to assess the efficacy and safety of a salt selenium mixture for supplementing range cows

Approximately a years data have been obtained on two groups each of 19 mature Hereford cows grazing range and offered two salt-selenium mineral mixtures free choice The concentration of selenium in one mixture was 40 ppm (low Se group) and the other 80 ppm (high Se group) These levels represent 2 and 4 times the maximal level currently permitted by FDA

Blood selenium concentrations (Figure 1) were determined on each animal at weekly intervals initially then at monthy intervals Intake of the salt-selenium mixture was also measured at monthly intervals to obtain total group mean intake of selenium

Blood selenium concentration rose from the initial concentration of 0035 ~gml to a maxima of approximately 0225 ~gm1 in the high group and 0150 ~gm1 in the low group at about 12 weeks Then maximal concentrations are within the range of normality and in no way indicate selenium toxicity

Intake of the salt-selenium mixture was not well correlated with blood concentration of se1eniUffl

Then data indicate that the FDA maximal level of 20 ppm selenium in salt supplements is conservative and may be ineffectual in areas of selenium deficiency There was no significant difference in the weight of the cows at the time the calves were weaned - low group 487 ~ 48 kg high group - 481 ~ 57 kg

SlJotMARY OF COMMENTS

The foothills of California offer an ideal place for people

to pursue farming Farming in the tradi tional sense family cerltered

labor interlsive small machinery oriented conservation minded small

Hopefully the U C Sierra Foothill Range Field Station will accept

and meet the challenge of providing research and information appropriate

to the fledgling development of a foothill agriculture ethic in which

the quality of food and living is paramount Projects of this nature

are few in the 1981 annual report Possibly we can make II greeter

contribution to foothill farming in the future

Early IrrIgation - Liquid Supplement Trial

RIck Delmas

This study was initiated In 1980 to study the performance of

cattle using liquid supplement and the effect of early irrigation of

annual grasslands for early fall growth on the performance of cattle

during the fall and winter grazing period

Though the trial needs to be continued for the next couple of

years the following are indicated from one years data

1) Early irrigation furnishes valuable early fall feed especially

in poor rainfall years

2) Liquid supplement doesnt appear to be as beneficial as concentrates

for young cattle during the fall and winter The conception rate

on cattle with only liquid supplement was 8 to 19 lower than on

the other three treatments Economically the liquid supplement

was half the cost or less of the concentrate excluding labor

From this sfandpoint alone a rancher may be wIlling to accept

a slightly lower conception rate to obtain the decreased labor

and supplement cost Each individual rancher must measure cost

versus production

EFFECT OF OAK TREE REMOVAL ON FORAGE PRODUCTION

1981 was the sixteenth year that forage production has been measured in this study I have considered terminating the measurements because yield increases have not been significant in three of the last four years (see table) However data show that increases were significant in all of the sixteen years in which forage production on the check treatment (area covered by live trees) was below the median of the period (1385 Ibacre) Therefore in the interest of economy only the check treatments will be sampled in high rainfall years If another poor feed year occurs soon we will measure all treatments

6 Progress Report (Progress uring report perio toward reaching objectives of this research) The Ecologv and Population Dynamics of Aphodius fimetarius

The ecological study of the dung beetle Aphodius fimetarius was continued by again monitoring the ability of males and females to hibshyernate (aestivate) from late Spring to Fall From May 29 through June 9 we collected and marked 3020 beetles with fluorescent dust Half of these were released into a beetle-proof screened field cage in the Scott 14 pasture and the other half were released into a s~milar cage at the Howarth pasture o Both cages enclosed about 30 ft of natural turf and each was supplied with fresh dung (beetle food) until no beetles were present These two cages were monitored for the re-eppearance of beetles from September through December and cattle droppings from various pastures were sampled for the presence of naturally appearing wild beetles

During the past year the first beetles appeared in pasture droppings on November 4 when the dung peds had an average of 27 beetlespad On different weeks from November 11 through December 11 the density of ~ fimetarius remained fairly stable at 29 21 23 end 25 beetlespad As in previous years the beetle density then began to decline with 15pad on December 15 and less than one per pad on January 7 1982 In the Fall of 1981 beetles that had been marked and released into the experimental cages first appeared in the Scott 14 pasture on November 9 5 days after beetles first appeared in cattle dung pads in pastures The marked beetles contshyinued to appear in the Scott 14 cage through December with one beetle last appearing on December 16 No beetles were recovered in the Howarth pasture cage and through December 16 only 1 of marked beetles had been recovered in the Scott 14 cage This is in marked contrast to the cage recapture rates of 57 in the Scott pasture and 104 in the Howarth pasture It appears that beetles marked with the fluorescent dust suffershyed heavy mortality most of the marked beetles recovered had only a few particles of dust under the elytra or under the membraneous wings Nevertheless recapture of marked beetles confirmed that ~ fimetarius naturally hibernates (aestivates) in the ground for about 5 months in this part of California Other methods of marking beetles will be tested during the next seaSon

6 Progress Report (Progress during report period toward reaching objectives of thi 5 research)

The objectives of this research were outlined in the 1980 report Many of the same trends observed in 1980 were repeated in 1981 Body weights of the cows were positively related to level of supplementation

(Table 1) The greatest effect was observed at the start of the breeding season where the difference between the unsupplemented and 25 times supplemented cows was nearly 100 kg

Weaning weight of the calves (Table 2) reflected the plane of nutrition of the cows Although weaning weights were enhanced by supplementation the largest differences in body weights occurred at the times the dams were mated Body weights of the calves reflected differential milk production of the cows

As in the previous year birth weight of the calves was not affected by plane of nutrition of the cows

6 Progress Report (Progress during report period toward reaching objectives of this research)

The major objectives of this research with Hereford cattle are (1) to determine if individual differences in mounting frequency by juvenile males correlate with individual differences in sexual motivation and performance as adults (2) to determine the degree of correlation between sexual behaviors and other biological traits (eg aggressive behavior semen characteristics hormone levels body size scrotal circumference) (3) to determine the function of mounting exshyperience on the development of sexual behavior and (4) to determine the role of penile stimulation on the development of sexual behavior

Over the last 4 years 78 bulls have been obtained from the SFRFS herd to investigate these questions Twenty-four male calves were brought to Davis from SFRFS in May 1981 to be used in studying objective 114 No observations were made on this group at the Field Station

Prior to 1981 all of our observations on juvenile mounting (Objectives 1 and 3) were made in confined situations where estrous heifers were provided as mountingstimuli and inter-animal contacts were frequent To determine the frequency of juvenile mounting in a more typical range environment 10 male and 9 female purebredHereford calves were observed between January 13 and March 22 1981 for a total of 40 hrs (29 different days) The calves ranged in age from 48 to 102 days (x = 80 days) at the start of observation A total of 394 calf observation hours were made on the 10 bull calves in the group and 749 calf hours on all 19 calves

Relative to our studies in confinement the rate of juvenile mounting in a typical range environment is very low A total of 15 mount intentions 12 mount attempts and 6 mounts (33 mount responses) were observed during the 40 hrs of observation Except for one mount intention all of the mounting activities were exhibited by bull calves The rate of mount responses was 0084 per bull calf per hour of observation Nearly all of the mounting behaviors were observed near the feed trough following feeding of supplements Supplemental feeding was terminated on February 25th and no sexual activity was observed among calves after that date

It was concluded that the mounting experience of 2-12 to 4-12 mo juvenilecalves in a ranqe environment is very limited

promising at present arc Monterey pine coast redwood and varieties of Pinus halepensis (brutia and eldarica) The most promising hardwoods to date are Eucalyptus globulus camaldulensis (2 variants) urnigera and grandis

In the lower Plot near the Yuba River deer and cattle damage al1d some porcupine debarking have greatly reduced the choice of species here The above pines Arizona cypress plus possibly tamarisk aphylla and coast redwood still appear promising

The North Plot after 3 years of trial plantings versus 4 for the other plots shows promising results for only Arizona cypress Eucalyptus grandis from 2 sources and tamarisk aphylla It is too early to rate the remainj~g species over-all survival rates of which are generally low

No fertilizer tablets have been applied to any of these plots because other factors limiting growth and survival appear more Important There was no serious rodent or insect damage noted in any of the 3 plots this past year and irrigation practices have been generally good probably supplying around 3 acre feet per growing season of about 6 months

It is now planned to establish semi-commercial plots of a minimum of 112 acre for each of at least 5 of the most promising species in another area of the Sierra Field Station

Development work continued in the Campbell Field A fall-1980 seeding of a perennia grass-legume pasture mixture on the new irrigated pasture areas was successful except for parts of some fields where irrigation water (surface flow) failed to reach In general the newly-installed irrigation system performed well

The following work was done on or related to the range fertilization study being conducted on the Forbes Flll44 series fields

a Soil samples were taken from each of the 16 fields Analyses will be made for P 5 Ca Mg K and pH

b In cooperation with M B Jones (HFS) field plots were established at eight locations (4 north-facing aspects 4 south-facing) A factorial design was used to compare 4 levels of N (as urea) and 4 levels of P (as low-S concentrated superphosphate) plus an exploratory for several combinations of NPS with two replications at each locati r

c Also in cooperation with M B Jones a greenhouse pot test was set up at the Hopland Field station with rate-element combinations to match those in the field plots using soil collected at the field locations for the eight replications The pots were seeded with a mixture of sub and rose clovers together with soft chess

d M R George and W J Clawson located sites for a grazing utilization study employing 10 x 10 exclosures

e A field-scale experiment with aerial application of nitrogen (as urea) at 0 40 80 and 120 kgha rates (two fields per replication two replications per treatment) is planned for fall 1982 following evaluation of the tests described above and results of a pre-experiment calibration grazing (with steers) beginning February 1982 Roy Hull J G Morris and R E Delmas are cooperators from the Department of Animal Science

6 Progress Report (Progress during report period toward reaching objectives of this research)

This is the third year in which numbers of infective parasite larvae on pasture has been assessed by placing 2 worm-free tracer calves on pasture at monthly intervals Since this is only one of several locations where these studies are being conducted not all laboratory analyses have been completedNevertheless studies over the three year period demonstrates the occurrence of infective nematode larvae on pastures is repetitive and predictable The season for the occurrence of disease producing numbers of various species differs little in such diverse regions as the San Joaquin Valley (Elk Grove) the East Slope of the Sierras (Susanville) or the Sierra Foothills (UCSFR) This studycorroborates the newly emerging concepts of safe and unsafe grazing periods The application of data from this study can be utilized in managerial decisions and thus in Integrated Pest (parasite) Control programs It is planned that trials designed to establish the value of these IPC programs will be initiated at several locations including UCSFR during the 1981-82 year

6 Progress Report (Progress during report period toward reaching objectives of this research)

Four pairs of 14 acre plots were established during the fall of 1979 The Blue Oak overstory of these paired plots was approximately 0 25 50 and 75 The tree overstory was removed from one set of four plots by February 15 1980 and 12 wire mesh igloo type cages were placed on all plots by December 1980 Cages were located under tree canopy (or former tree canopy) and in the open using a stratified random procedure with proportional allocation

During 1981 three successive clippings were taken from inside the wire cages to determine the total standing crop present on February 21 (early season) April 3 amp 4 (mid-season) and June 2 (late season)

Preliminary Results (1981)

Uncleared plots 25 50 and 75 overstory cover Standing crop at any season did not differ appreciably by overstory level (Fig 1) When compared with uncleared open (0 overstory cover) plots standing crop was significantly less in uncleared plots at late season but not at early and mid-season Overstory cover and standing crop are not significantly correlated for any season (Fig 2)

Cleared Plots 25 50 and 75 prior overstory cover Standing crop is positively correlated with prior overstory cover particularly when uncleared open (0 overstory cover) plots are included in the comparison (Fig 2)

Tree removal greatly increased standing crop at all three seasons of harvest for all overstory cover levels (Fig 1) When compared to uncleared plots of the same overstory cover level these increases were 100 early season 133 midshyseason and 80 late season

During the first phase of the trial we are observing tropical plants Varieties were I isted in last year1s report The Leucaena species was eliminated Last winter was a relatively mild winter thus we feel we did not obtain good cold readings on the other species Further observations will be made this coming year

In the second phase we have planted species and varieties of Orchardgrass Tall Fescue and Perennial Ryegrass from the Georgia Plant Station In addition planted species of the same plants used in California irrigated pastures Stand evaluations were made on all species this past year only This coming year we will obtain yield data

The major objective of this study is to determine differences in the maternal care provided tw1n calves relative to the maternal behavior of cows with singleoffspring when placed 1n a range environment Observations were conducted duringJanuary February and March 1981 at SFRFS on 7 cows with single calves and 5 cows with twins housed in a 75A pasture The animals were observed for 15 hrs per week during the f1rst two hrs following sunrise and the two hrs preceding sunset

Data collected on mothers included frequency and duration of licking (grooming) calves vocalizattons butts and butt attempts directed at alien calves and behavioral responses to separatton from calf(ves) Calves were observed for frequency and duration of sucking on own and aUen mothers frequency and duration of resting runn1ng laying and grazing frequency of vocalizations and juvenilemounting and prox1m1ty to mother tw1n and nea~est unrelated calf

The data have been compiled but have not yet been analyzed statistically

Efficacy of sall as a vehicle for selenium supplementatio~

4 Project Leader J G Morri 5 1 5 bull Period Covered QL sectL - 1L A by this Report mo yr mo yr

6 Progress Report (Progress during report period toward reaching objectives of this research)

This experiment was undertaken to assess the efficacy and safety of a salt selenium mixture for supplementing range cows

Approximately a years data have been obtained on two groups each of 19 mature Hereford cows grazing range and offered two salt-selenium mineral mixtures free choice The concentration of selenium in one mixture was 40 ppm (low Se group) and the other 80 ppm (high Se group) These levels represent 2 and 4 times the maximal level currently permitted by FDA

Blood selenium concentrations (Figure 1) were determined on each animal at weekly intervals initially then at monthy intervals Intake of the salt-selenium mixture was also measured at monthly intervals to obtain total group mean intake of selenium

Blood selenium concentration rose from the initial concentration of 0035 ~gml to a maxima of approximately 0225 ~gm1 in the high group and 0150 ~gm1 in the low group at about 12 weeks Then maximal concentrations are within the range of normality and in no way indicate selenium toxicity

Intake of the salt-selenium mixture was not well correlated with blood concentration of se1eniUffl

Then data indicate that the FDA maximal level of 20 ppm selenium in salt supplements is conservative and may be ineffectual in areas of selenium deficiency There was no significant difference in the weight of the cows at the time the calves were weaned - low group 487 ~ 48 kg high group - 481 ~ 57 kg

SlJotMARY OF COMMENTS

The foothills of California offer an ideal place for people

to pursue farming Farming in the tradi tional sense family cerltered

labor interlsive small machinery oriented conservation minded small

Hopefully the U C Sierra Foothill Range Field Station will accept

and meet the challenge of providing research and information appropriate

to the fledgling development of a foothill agriculture ethic in which

the quality of food and living is paramount Projects of this nature

are few in the 1981 annual report Possibly we can make II greeter

contribution to foothill farming in the future

EFFECT OF OAK TREE REMOVAL ON FORAGE PRODUCTION

1981 was the sixteenth year that forage production has been measured in this study I have considered terminating the measurements because yield increases have not been significant in three of the last four years (see table) However data show that increases were significant in all of the sixteen years in which forage production on the check treatment (area covered by live trees) was below the median of the period (1385 Ibacre) Therefore in the interest of economy only the check treatments will be sampled in high rainfall years If another poor feed year occurs soon we will measure all treatments

6 Progress Report (Progress uring report perio toward reaching objectives of this research) The Ecologv and Population Dynamics of Aphodius fimetarius

The ecological study of the dung beetle Aphodius fimetarius was continued by again monitoring the ability of males and females to hibshyernate (aestivate) from late Spring to Fall From May 29 through June 9 we collected and marked 3020 beetles with fluorescent dust Half of these were released into a beetle-proof screened field cage in the Scott 14 pasture and the other half were released into a s~milar cage at the Howarth pasture o Both cages enclosed about 30 ft of natural turf and each was supplied with fresh dung (beetle food) until no beetles were present These two cages were monitored for the re-eppearance of beetles from September through December and cattle droppings from various pastures were sampled for the presence of naturally appearing wild beetles

During the past year the first beetles appeared in pasture droppings on November 4 when the dung peds had an average of 27 beetlespad On different weeks from November 11 through December 11 the density of ~ fimetarius remained fairly stable at 29 21 23 end 25 beetlespad As in previous years the beetle density then began to decline with 15pad on December 15 and less than one per pad on January 7 1982 In the Fall of 1981 beetles that had been marked and released into the experimental cages first appeared in the Scott 14 pasture on November 9 5 days after beetles first appeared in cattle dung pads in pastures The marked beetles contshyinued to appear in the Scott 14 cage through December with one beetle last appearing on December 16 No beetles were recovered in the Howarth pasture cage and through December 16 only 1 of marked beetles had been recovered in the Scott 14 cage This is in marked contrast to the cage recapture rates of 57 in the Scott pasture and 104 in the Howarth pasture It appears that beetles marked with the fluorescent dust suffershyed heavy mortality most of the marked beetles recovered had only a few particles of dust under the elytra or under the membraneous wings Nevertheless recapture of marked beetles confirmed that ~ fimetarius naturally hibernates (aestivates) in the ground for about 5 months in this part of California Other methods of marking beetles will be tested during the next seaSon

The objectives of this research were outlined in the 1980 report Many of the same trends observed in 1980 were repeated in 1981 Body weights of the cows were positively related to level of supplementation

(Table 1) The greatest effect was observed at the start of the breeding season where the difference between the unsupplemented and 25 times supplemented cows was nearly 100 kg

Weaning weight of the calves (Table 2) reflected the plane of nutrition of the cows Although weaning weights were enhanced by supplementation the largest differences in body weights occurred at the times the dams were mated Body weights of the calves reflected differential milk production of the cows

As in the previous year birth weight of the calves was not affected by plane of nutrition of the cows

6 Progress Report (Progress during report period toward reaching objectives of this research)

The major objectives of this research with Hereford cattle are (1) to determine if individual differences in mounting frequency by juvenile males correlate with individual differences in sexual motivation and performance as adults (2) to determine the degree of correlation between sexual behaviors and other biological traits (eg aggressive behavior semen characteristics hormone levels body size scrotal circumference) (3) to determine the function of mounting exshyperience on the development of sexual behavior and (4) to determine the role of penile stimulation on the development of sexual behavior

Over the last 4 years 78 bulls have been obtained from the SFRFS herd to investigate these questions Twenty-four male calves were brought to Davis from SFRFS in May 1981 to be used in studying objective 114 No observations were made on this group at the Field Station

Prior to 1981 all of our observations on juvenile mounting (Objectives 1 and 3) were made in confined situations where estrous heifers were provided as mountingstimuli and inter-animal contacts were frequent To determine the frequency of juvenile mounting in a more typical range environment 10 male and 9 female purebredHereford calves were observed between January 13 and March 22 1981 for a total of 40 hrs (29 different days) The calves ranged in age from 48 to 102 days (x = 80 days) at the start of observation A total of 394 calf observation hours were made on the 10 bull calves in the group and 749 calf hours on all 19 calves

Relative to our studies in confinement the rate of juvenile mounting in a typical range environment is very low A total of 15 mount intentions 12 mount attempts and 6 mounts (33 mount responses) were observed during the 40 hrs of observation Except for one mount intention all of the mounting activities were exhibited by bull calves The rate of mount responses was 0084 per bull calf per hour of observation Nearly all of the mounting behaviors were observed near the feed trough following feeding of supplements Supplemental feeding was terminated on February 25th and no sexual activity was observed among calves after that date

It was concluded that the mounting experience of 2-12 to 4-12 mo juvenilecalves in a ranqe environment is very limited

promising at present arc Monterey pine coast redwood and varieties of Pinus halepensis (brutia and eldarica) The most promising hardwoods to date are Eucalyptus globulus camaldulensis (2 variants) urnigera and grandis

In the lower Plot near the Yuba River deer and cattle damage al1d some porcupine debarking have greatly reduced the choice of species here The above pines Arizona cypress plus possibly tamarisk aphylla and coast redwood still appear promising

The North Plot after 3 years of trial plantings versus 4 for the other plots shows promising results for only Arizona cypress Eucalyptus grandis from 2 sources and tamarisk aphylla It is too early to rate the remainj~g species over-all survival rates of which are generally low

No fertilizer tablets have been applied to any of these plots because other factors limiting growth and survival appear more Important There was no serious rodent or insect damage noted in any of the 3 plots this past year and irrigation practices have been generally good probably supplying around 3 acre feet per growing season of about 6 months

It is now planned to establish semi-commercial plots of a minimum of 112 acre for each of at least 5 of the most promising species in another area of the Sierra Field Station

Development work continued in the Campbell Field A fall-1980 seeding of a perennia grass-legume pasture mixture on the new irrigated pasture areas was successful except for parts of some fields where irrigation water (surface flow) failed to reach In general the newly-installed irrigation system performed well

The following work was done on or related to the range fertilization study being conducted on the Forbes Flll44 series fields

a Soil samples were taken from each of the 16 fields Analyses will be made for P 5 Ca Mg K and pH

b In cooperation with M B Jones (HFS) field plots were established at eight locations (4 north-facing aspects 4 south-facing) A factorial design was used to compare 4 levels of N (as urea) and 4 levels of P (as low-S concentrated superphosphate) plus an exploratory for several combinations of NPS with two replications at each locati r

c Also in cooperation with M B Jones a greenhouse pot test was set up at the Hopland Field station with rate-element combinations to match those in the field plots using soil collected at the field locations for the eight replications The pots were seeded with a mixture of sub and rose clovers together with soft chess

d M R George and W J Clawson located sites for a grazing utilization study employing 10 x 10 exclosures

e A field-scale experiment with aerial application of nitrogen (as urea) at 0 40 80 and 120 kgha rates (two fields per replication two replications per treatment) is planned for fall 1982 following evaluation of the tests described above and results of a pre-experiment calibration grazing (with steers) beginning February 1982 Roy Hull J G Morris and R E Delmas are cooperators from the Department of Animal Science

f Using Sobrante-Las Posas soil collected at the SFRFS a study of effects of levels of single superphosphate with and without N and effects of fertiizer placement on emergence growth and nodulation of sub clover was completed at Davis- bull

This is the third year in which numbers of infective parasite larvae on pasture has been assessed by placing 2 worm-free tracer calves on pasture at monthly intervals Since this is only one of several locations where these studies are being conducted not all laboratory analyses have been completedNevertheless studies over the three year period demonstrates the occurrence of infective nematode larvae on pastures is repetitive and predictable The season for the occurrence of disease producing numbers of various species differs little in such diverse regions as the San Joaquin Valley (Elk Grove) the East Slope of the Sierras (Susanville) or the Sierra Foothills (UCSFR) This studycorroborates the newly emerging concepts of safe and unsafe grazing periods The application of data from this study can be utilized in managerial decisions and thus in Integrated Pest (parasite) Control programs It is planned that trials designed to establish the value of these IPC programs will be initiated at several locations including UCSFR during the 1981-82 year

6 Progress Report (Progress during report period toward reaching objectives of this research)

Four pairs of 14 acre plots were established during the fall of 1979 The Blue Oak overstory of these paired plots was approximately 0 25 50 and 75 The tree overstory was removed from one set of four plots by February 15 1980 and 12 wire mesh igloo type cages were placed on all plots by December 1980 Cages were located under tree canopy (or former tree canopy) and in the open using a stratified random procedure with proportional allocation

During 1981 three successive clippings were taken from inside the wire cages to determine the total standing crop present on February 21 (early season) April 3 amp 4 (mid-season) and June 2 (late season)

Preliminary Results (1981)

Uncleared plots 25 50 and 75 overstory cover Standing crop at any season did not differ appreciably by overstory level (Fig 1) When compared with uncleared open (0 overstory cover) plots standing crop was significantly less in uncleared plots at late season but not at early and mid-season Overstory cover and standing crop are not significantly correlated for any season (Fig 2)

Cleared Plots 25 50 and 75 prior overstory cover Standing crop is positively correlated with prior overstory cover particularly when uncleared open (0 overstory cover) plots are included in the comparison (Fig 2)

Tree removal greatly increased standing crop at all three seasons of harvest for all overstory cover levels (Fig 1) When compared to uncleared plots of the same overstory cover level these increases were 100 early season 133 midshyseason and 80 late season

During the first phase of the trial we are observing tropical plants Varieties were I isted in last year1s report The Leucaena species was eliminated Last winter was a relatively mild winter thus we feel we did not obtain good cold readings on the other species Further observations will be made this coming year

In the second phase we have planted species and varieties of Orchardgrass Tall Fescue and Perennial Ryegrass from the Georgia Plant Station In addition planted species of the same plants used in California irrigated pastures Stand evaluations were made on all species this past year only This coming year we will obtain yield data

The major objective of this study is to determine differences in the maternal care provided tw1n calves relative to the maternal behavior of cows with singleoffspring when placed 1n a range environment Observations were conducted duringJanuary February and March 1981 at SFRFS on 7 cows with single calves and 5 cows with twins housed in a 75A pasture The animals were observed for 15 hrs per week during the f1rst two hrs following sunrise and the two hrs preceding sunset

Data collected on mothers included frequency and duration of licking (grooming) calves vocalizattons butts and butt attempts directed at alien calves and behavioral responses to separatton from calf(ves) Calves were observed for frequency and duration of sucking on own and aUen mothers frequency and duration of resting runn1ng laying and grazing frequency of vocalizations and juvenilemounting and prox1m1ty to mother tw1n and nea~est unrelated calf

The data have been compiled but have not yet been analyzed statistically

Efficacy of sall as a vehicle for selenium supplementatio~

6 Progress Report (Progress during report period toward reaching objectives of this research)

This experiment was undertaken to assess the efficacy and safety of a salt selenium mixture for supplementing range cows

Approximately a years data have been obtained on two groups each of 19 mature Hereford cows grazing range and offered two salt-selenium mineral mixtures free choice The concentration of selenium in one mixture was 40 ppm (low Se group) and the other 80 ppm (high Se group) These levels represent 2 and 4 times the maximal level currently permitted by FDA

Blood selenium concentrations (Figure 1) were determined on each animal at weekly intervals initially then at monthy intervals Intake of the salt-selenium mixture was also measured at monthly intervals to obtain total group mean intake of selenium

Blood selenium concentration rose from the initial concentration of 0035 ~gml to a maxima of approximately 0225 ~gm1 in the high group and 0150 ~gm1 in the low group at about 12 weeks Then maximal concentrations are within the range of normality and in no way indicate selenium toxicity

Intake of the salt-selenium mixture was not well correlated with blood concentration of se1eniUffl

Then data indicate that the FDA maximal level of 20 ppm selenium in salt supplements is conservative and may be ineffectual in areas of selenium deficiency There was no significant difference in the weight of the cows at the time the calves were weaned - low group 487 ~ 48 kg high group - 481 ~ 57 kg

SlJotMARY OF COMMENTS

The foothills of California offer an ideal place for people

to pursue farming Farming in the tradi tional sense family cerltered

labor interlsive small machinery oriented conservation minded small

Hopefully the U C Sierra Foothill Range Field Station will accept

and meet the challenge of providing research and information appropriate

to the fledgling development of a foothill agriculture ethic in which

the quality of food and living is paramount Projects of this nature

are few in the 1981 annual report Possibly we can make II greeter

contribution to foothill farming in the future

EFFECT OF OAK TREE REMOVAL ON FORAGE PRODUCTION

1981 was the sixteenth year that forage production has been measured in this study I have considered terminating the measurements because yield increases have not been significant in three of the last four years (see table) However data show that increases were significant in all of the sixteen years in which forage production on the check treatment (area covered by live trees) was below the median of the period (1385 Ibacre) Therefore in the interest of economy only the check treatments will be sampled in high rainfall years If another poor feed year occurs soon we will measure all treatments

6 Progress Report (Progress uring report perio toward reaching objectives of this research) The Ecologv and Population Dynamics of Aphodius fimetarius

The ecological study of the dung beetle Aphodius fimetarius was continued by again monitoring the ability of males and females to hibshyernate (aestivate) from late Spring to Fall From May 29 through June 9 we collected and marked 3020 beetles with fluorescent dust Half of these were released into a beetle-proof screened field cage in the Scott 14 pasture and the other half were released into a s~milar cage at the Howarth pasture o Both cages enclosed about 30 ft of natural turf and each was supplied with fresh dung (beetle food) until no beetles were present These two cages were monitored for the re-eppearance of beetles from September through December and cattle droppings from various pastures were sampled for the presence of naturally appearing wild beetles

During the past year the first beetles appeared in pasture droppings on November 4 when the dung peds had an average of 27 beetlespad On different weeks from November 11 through December 11 the density of ~ fimetarius remained fairly stable at 29 21 23 end 25 beetlespad As in previous years the beetle density then began to decline with 15pad on December 15 and less than one per pad on January 7 1982 In the Fall of 1981 beetles that had been marked and released into the experimental cages first appeared in the Scott 14 pasture on November 9 5 days after beetles first appeared in cattle dung pads in pastures The marked beetles contshyinued to appear in the Scott 14 cage through December with one beetle last appearing on December 16 No beetles were recovered in the Howarth pasture cage and through December 16 only 1 of marked beetles had been recovered in the Scott 14 cage This is in marked contrast to the cage recapture rates of 57 in the Scott pasture and 104 in the Howarth pasture It appears that beetles marked with the fluorescent dust suffershyed heavy mortality most of the marked beetles recovered had only a few particles of dust under the elytra or under the membraneous wings Nevertheless recapture of marked beetles confirmed that ~ fimetarius naturally hibernates (aestivates) in the ground for about 5 months in this part of California Other methods of marking beetles will be tested during the next seaSon

The objectives of this research were outlined in the 1980 report Many of the same trends observed in 1980 were repeated in 1981 Body weights of the cows were positively related to level of supplementation

(Table 1) The greatest effect was observed at the start of the breeding season where the difference between the unsupplemented and 25 times supplemented cows was nearly 100 kg

Weaning weight of the calves (Table 2) reflected the plane of nutrition of the cows Although weaning weights were enhanced by supplementation the largest differences in body weights occurred at the times the dams were mated Body weights of the calves reflected differential milk production of the cows

As in the previous year birth weight of the calves was not affected by plane of nutrition of the cows

6 Progress Report (Progress during report period toward reaching objectives of this research)

The major objectives of this research with Hereford cattle are (1) to determine if individual differences in mounting frequency by juvenile males correlate with individual differences in sexual motivation and performance as adults (2) to determine the degree of correlation between sexual behaviors and other biological traits (eg aggressive behavior semen characteristics hormone levels body size scrotal circumference) (3) to determine the function of mounting exshyperience on the development of sexual behavior and (4) to determine the role of penile stimulation on the development of sexual behavior

Over the last 4 years 78 bulls have been obtained from the SFRFS herd to investigate these questions Twenty-four male calves were brought to Davis from SFRFS in May 1981 to be used in studying objective 114 No observations were made on this group at the Field Station

Prior to 1981 all of our observations on juvenile mounting (Objectives 1 and 3) were made in confined situations where estrous heifers were provided as mountingstimuli and inter-animal contacts were frequent To determine the frequency of juvenile mounting in a more typical range environment 10 male and 9 female purebredHereford calves were observed between January 13 and March 22 1981 for a total of 40 hrs (29 different days) The calves ranged in age from 48 to 102 days (x = 80 days) at the start of observation A total of 394 calf observation hours were made on the 10 bull calves in the group and 749 calf hours on all 19 calves

Relative to our studies in confinement the rate of juvenile mounting in a typical range environment is very low A total of 15 mount intentions 12 mount attempts and 6 mounts (33 mount responses) were observed during the 40 hrs of observation Except for one mount intention all of the mounting activities were exhibited by bull calves The rate of mount responses was 0084 per bull calf per hour of observation Nearly all of the mounting behaviors were observed near the feed trough following feeding of supplements Supplemental feeding was terminated on February 25th and no sexual activity was observed among calves after that date

It was concluded that the mounting experience of 2-12 to 4-12 mo juvenilecalves in a ranqe environment is very limited

promising at present arc Monterey pine coast redwood and varieties of Pinus halepensis (brutia and eldarica) The most promising hardwoods to date are Eucalyptus globulus camaldulensis (2 variants) urnigera and grandis

In the lower Plot near the Yuba River deer and cattle damage al1d some porcupine debarking have greatly reduced the choice of species here The above pines Arizona cypress plus possibly tamarisk aphylla and coast redwood still appear promising

The North Plot after 3 years of trial plantings versus 4 for the other plots shows promising results for only Arizona cypress Eucalyptus grandis from 2 sources and tamarisk aphylla It is too early to rate the remainj~g species over-all survival rates of which are generally low

No fertilizer tablets have been applied to any of these plots because other factors limiting growth and survival appear more Important There was no serious rodent or insect damage noted in any of the 3 plots this past year and irrigation practices have been generally good probably supplying around 3 acre feet per growing season of about 6 months

It is now planned to establish semi-commercial plots of a minimum of 112 acre for each of at least 5 of the most promising species in another area of the Sierra Field Station

Development work continued in the Campbell Field A fall-1980 seeding of a perennia grass-legume pasture mixture on the new irrigated pasture areas was successful except for parts of some fields where irrigation water (surface flow) failed to reach In general the newly-installed irrigation system performed well

The following work was done on or related to the range fertilization study being conducted on the Forbes Flll44 series fields

a Soil samples were taken from each of the 16 fields Analyses will be made for P 5 Ca Mg K and pH

b In cooperation with M B Jones (HFS) field plots were established at eight locations (4 north-facing aspects 4 south-facing) A factorial design was used to compare 4 levels of N (as urea) and 4 levels of P (as low-S concentrated superphosphate) plus an exploratory for several combinations of NPS with two replications at each locati r

c Also in cooperation with M B Jones a greenhouse pot test was set up at the Hopland Field station with rate-element combinations to match those in the field plots using soil collected at the field locations for the eight replications The pots were seeded with a mixture of sub and rose clovers together with soft chess

d M R George and W J Clawson located sites for a grazing utilization study employing 10 x 10 exclosures

e A field-scale experiment with aerial application of nitrogen (as urea) at 0 40 80 and 120 kgha rates (two fields per replication two replications per treatment) is planned for fall 1982 following evaluation of the tests described above and results of a pre-experiment calibration grazing (with steers) beginning February 1982 Roy Hull J G Morris and R E Delmas are cooperators from the Department of Animal Science

Uncleared plots 25 50 and 75 overstory cover Standing crop at any season did not differ appreciably by overstory level (Fig 1) When compared with uncleared open (0 overstory cover) plots standing crop was significantly less in uncleared plots at late season but not at early and mid-season Overstory cover and standing crop are not significantly correlated for any season (Fig 2)

Cleared Plots 25 50 and 75 prior overstory cover Standing crop is positively correlated with prior overstory cover particularly when uncleared open (0 overstory cover) plots are included in the comparison (Fig 2)

Tree removal greatly increased standing crop at all three seasons of harvest for all overstory cover levels (Fig 1) When compared to uncleared plots of the same overstory cover level these increases were 100 early season 133 midshyseason and 80 late season

During the first phase of the trial we are observing tropical plants Varieties were I isted in last year1s report The Leucaena species was eliminated Last winter was a relatively mild winter thus we feel we did not obtain good cold readings on the other species Further observations will be made this coming year

In the second phase we have planted species and varieties of Orchardgrass Tall Fescue and Perennial Ryegrass from the Georgia Plant Station In addition planted species of the same plants used in California irrigated pastures Stand evaluations were made on all species this past year only This coming year we will obtain yield data

The major objective of this study is to determine differences in the maternal care provided tw1n calves relative to the maternal behavior of cows with singleoffspring when placed 1n a range environment Observations were conducted duringJanuary February and March 1981 at SFRFS on 7 cows with single calves and 5 cows with twins housed in a 75A pasture The animals were observed for 15 hrs per week during the f1rst two hrs following sunrise and the two hrs preceding sunset

Data collected on mothers included frequency and duration of licking (grooming) calves vocalizattons butts and butt attempts directed at alien calves and behavioral responses to separatton from calf(ves) Calves were observed for frequency and duration of sucking on own and aUen mothers frequency and duration of resting runn1ng laying and grazing frequency of vocalizations and juvenilemounting and prox1m1ty to mother tw1n and nea~est unrelated calf

The data have been compiled but have not yet been analyzed statistically

Efficacy of sall as a vehicle for selenium supplementatio~

4 Project Leader J G Morri 5 1 5 bull Period Covered QL sectL - 1L A by this Report mo yr mo yr

6 Progress Report (Progress during report period toward reaching objectives of this research)

This experiment was undertaken to assess the efficacy and safety of a salt selenium mixture for supplementing range cows

Approximately a years data have been obtained on two groups each of 19 mature Hereford cows grazing range and offered two salt-selenium mineral mixtures free choice The concentration of selenium in one mixture was 40 ppm (low Se group) and the other 80 ppm (high Se group) These levels represent 2 and 4 times the maximal level currently permitted by FDA

Blood selenium concentrations (Figure 1) were determined on each animal at weekly intervals initially then at monthy intervals Intake of the salt-selenium mixture was also measured at monthly intervals to obtain total group mean intake of selenium

Blood selenium concentration rose from the initial concentration of 0035 ~gml to a maxima of approximately 0225 ~gm1 in the high group and 0150 ~gm1 in the low group at about 12 weeks Then maximal concentrations are within the range of normality and in no way indicate selenium toxicity

Intake of the salt-selenium mixture was not well correlated with blood concentration of se1eniUffl

Then data indicate that the FDA maximal level of 20 ppm selenium in salt supplements is conservative and may be ineffectual in areas of selenium deficiency There was no significant difference in the weight of the cows at the time the calves were weaned - low group 487 ~ 48 kg high group - 481 ~ 57 kg

SlJotMARY OF COMMENTS

The foothills of California offer an ideal place for people

to pursue farming Farming in the tradi tional sense family cerltered

labor interlsive small machinery oriented conservation minded small

Hopefully the U C Sierra Foothill Range Field Station will accept

and meet the challenge of providing research and information appropriate

to the fledgling development of a foothill agriculture ethic in which

the quality of food and living is paramount Projects of this nature

are few in the 1981 annual report Possibly we can make II greeter

contribution to foothill farming in the future

6 Progress Report (Progress uring report perio toward reaching objectives of this research) The Ecologv and Population Dynamics of Aphodius fimetarius

The ecological study of the dung beetle Aphodius fimetarius was continued by again monitoring the ability of males and females to hibshyernate (aestivate) from late Spring to Fall From May 29 through June 9 we collected and marked 3020 beetles with fluorescent dust Half of these were released into a beetle-proof screened field cage in the Scott 14 pasture and the other half were released into a s~milar cage at the Howarth pasture o Both cages enclosed about 30 ft of natural turf and each was supplied with fresh dung (beetle food) until no beetles were present These two cages were monitored for the re-eppearance of beetles from September through December and cattle droppings from various pastures were sampled for the presence of naturally appearing wild beetles

During the past year the first beetles appeared in pasture droppings on November 4 when the dung peds had an average of 27 beetlespad On different weeks from November 11 through December 11 the density of ~ fimetarius remained fairly stable at 29 21 23 end 25 beetlespad As in previous years the beetle density then began to decline with 15pad on December 15 and less than one per pad on January 7 1982 In the Fall of 1981 beetles that had been marked and released into the experimental cages first appeared in the Scott 14 pasture on November 9 5 days after beetles first appeared in cattle dung pads in pastures The marked beetles contshyinued to appear in the Scott 14 cage through December with one beetle last appearing on December 16 No beetles were recovered in the Howarth pasture cage and through December 16 only 1 of marked beetles had been recovered in the Scott 14 cage This is in marked contrast to the cage recapture rates of 57 in the Scott pasture and 104 in the Howarth pasture It appears that beetles marked with the fluorescent dust suffershyed heavy mortality most of the marked beetles recovered had only a few particles of dust under the elytra or under the membraneous wings Nevertheless recapture of marked beetles confirmed that ~ fimetarius naturally hibernates (aestivates) in the ground for about 5 months in this part of California Other methods of marking beetles will be tested during the next seaSon

An evaluation was undertaken of the necessity for vitamin A supplementation of range cows

A group of 12 cows were grazed on range without access to irrigated pasture or B carotene supplements At monthly intervals over the past year liver biopsies were performed and blood collected for carotene and vitamin A determinations

At no time did circulating vitamin A concentrations indicate that supplementation was necessary

The relationship between hepatic reserves and circulating levels is being examined

The objectives of this research were outlined in the 1980 report Many of the same trends observed in 1980 were repeated in 1981 Body weights of the cows were positively related to level of supplementation

(Table 1) The greatest effect was observed at the start of the breeding season where the difference between the unsupplemented and 25 times supplemented cows was nearly 100 kg

Weaning weight of the calves (Table 2) reflected the plane of nutrition of the cows Although weaning weights were enhanced by supplementation the largest differences in body weights occurred at the times the dams were mated Body weights of the calves reflected differential milk production of the cows

As in the previous year birth weight of the calves was not affected by plane of nutrition of the cows

6 Progress Report (Progress during report period toward reaching objectives of this research)

The major objectives of this research with Hereford cattle are (1) to determine if individual differences in mounting frequency by juvenile males correlate with individual differences in sexual motivation and performance as adults (2) to determine the degree of correlation between sexual behaviors and other biological traits (eg aggressive behavior semen characteristics hormone levels body size scrotal circumference) (3) to determine the function of mounting exshyperience on the development of sexual behavior and (4) to determine the role of penile stimulation on the development of sexual behavior

Over the last 4 years 78 bulls have been obtained from the SFRFS herd to investigate these questions Twenty-four male calves were brought to Davis from SFRFS in May 1981 to be used in studying objective 114 No observations were made on this group at the Field Station

Prior to 1981 all of our observations on juvenile mounting (Objectives 1 and 3) were made in confined situations where estrous heifers were provided as mountingstimuli and inter-animal contacts were frequent To determine the frequency of juvenile mounting in a more typical range environment 10 male and 9 female purebredHereford calves were observed between January 13 and March 22 1981 for a total of 40 hrs (29 different days) The calves ranged in age from 48 to 102 days (x = 80 days) at the start of observation A total of 394 calf observation hours were made on the 10 bull calves in the group and 749 calf hours on all 19 calves

Relative to our studies in confinement the rate of juvenile mounting in a typical range environment is very low A total of 15 mount intentions 12 mount attempts and 6 mounts (33 mount responses) were observed during the 40 hrs of observation Except for one mount intention all of the mounting activities were exhibited by bull calves The rate of mount responses was 0084 per bull calf per hour of observation Nearly all of the mounting behaviors were observed near the feed trough following feeding of supplements Supplemental feeding was terminated on February 25th and no sexual activity was observed among calves after that date

It was concluded that the mounting experience of 2-12 to 4-12 mo juvenilecalves in a ranqe environment is very limited

promising at present arc Monterey pine coast redwood and varieties of Pinus halepensis (brutia and eldarica) The most promising hardwoods to date are Eucalyptus globulus camaldulensis (2 variants) urnigera and grandis

In the lower Plot near the Yuba River deer and cattle damage al1d some porcupine debarking have greatly reduced the choice of species here The above pines Arizona cypress plus possibly tamarisk aphylla and coast redwood still appear promising

The North Plot after 3 years of trial plantings versus 4 for the other plots shows promising results for only Arizona cypress Eucalyptus grandis from 2 sources and tamarisk aphylla It is too early to rate the remainj~g species over-all survival rates of which are generally low

No fertilizer tablets have been applied to any of these plots because other factors limiting growth and survival appear more Important There was no serious rodent or insect damage noted in any of the 3 plots this past year and irrigation practices have been generally good probably supplying around 3 acre feet per growing season of about 6 months

It is now planned to establish semi-commercial plots of a minimum of 112 acre for each of at least 5 of the most promising species in another area of the Sierra Field Station

Development work continued in the Campbell Field A fall-1980 seeding of a perennia grass-legume pasture mixture on the new irrigated pasture areas was successful except for parts of some fields where irrigation water (surface flow) failed to reach In general the newly-installed irrigation system performed well

The following work was done on or related to the range fertilization study being conducted on the Forbes Flll44 series fields

a Soil samples were taken from each of the 16 fields Analyses will be made for P 5 Ca Mg K and pH

b In cooperation with M B Jones (HFS) field plots were established at eight locations (4 north-facing aspects 4 south-facing) A factorial design was used to compare 4 levels of N (as urea) and 4 levels of P (as low-S concentrated superphosphate) plus an exploratory for several combinations of NPS with two replications at each locati r

c Also in cooperation with M B Jones a greenhouse pot test was set up at the Hopland Field station with rate-element combinations to match those in the field plots using soil collected at the field locations for the eight replications The pots were seeded with a mixture of sub and rose clovers together with soft chess

d M R George and W J Clawson located sites for a grazing utilization study employing 10 x 10 exclosures

e A field-scale experiment with aerial application of nitrogen (as urea) at 0 40 80 and 120 kgha rates (two fields per replication two replications per treatment) is planned for fall 1982 following evaluation of the tests described above and results of a pre-experiment calibration grazing (with steers) beginning February 1982 Roy Hull J G Morris and R E Delmas are cooperators from the Department of Animal Science

6 Progress Report (Progress during report period toward reaching objectives of this research)

Four pairs of 14 acre plots were established during the fall of 1979 The Blue Oak overstory of these paired plots was approximately 0 25 50 and 75 The tree overstory was removed from one set of four plots by February 15 1980 and 12 wire mesh igloo type cages were placed on all plots by December 1980 Cages were located under tree canopy (or former tree canopy) and in the open using a stratified random procedure with proportional allocation

During 1981 three successive clippings were taken from inside the wire cages to determine the total standing crop present on February 21 (early season) April 3 amp 4 (mid-season) and June 2 (late season)

Preliminary Results (1981)

Uncleared plots 25 50 and 75 overstory cover Standing crop at any season did not differ appreciably by overstory level (Fig 1) When compared with uncleared open (0 overstory cover) plots standing crop was significantly less in uncleared plots at late season but not at early and mid-season Overstory cover and standing crop are not significantly correlated for any season (Fig 2)

Cleared Plots 25 50 and 75 prior overstory cover Standing crop is positively correlated with prior overstory cover particularly when uncleared open (0 overstory cover) plots are included in the comparison (Fig 2)

Tree removal greatly increased standing crop at all three seasons of harvest for all overstory cover levels (Fig 1) When compared to uncleared plots of the same overstory cover level these increases were 100 early season 133 midshyseason and 80 late season

6 Progress Report (Progress during report perlod toward reaching objectives of this research)

The major objective of this study is to determine differences in the maternal care provided tw1n calves relative to the maternal behavior of cows with singleoffspring when placed 1n a range environment Observations were conducted duringJanuary February and March 1981 at SFRFS on 7 cows with single calves and 5 cows with twins housed in a 75A pasture The animals were observed for 15 hrs per week during the f1rst two hrs following sunrise and the two hrs preceding sunset

Data collected on mothers included frequency and duration of licking (grooming) calves vocalizattons butts and butt attempts directed at alien calves and behavioral responses to separatton from calf(ves) Calves were observed for frequency and duration of sucking on own and aUen mothers frequency and duration of resting runn1ng laying and grazing frequency of vocalizations and juvenilemounting and prox1m1ty to mother tw1n and nea~est unrelated calf

The data have been compiled but have not yet been analyzed statistically

Efficacy of sall as a vehicle for selenium supplementatio~

6 Progress Report (Progress during report period toward reaching objectives of this research)

This experiment was undertaken to assess the efficacy and safety of a salt selenium mixture for supplementing range cows

Approximately a years data have been obtained on two groups each of 19 mature Hereford cows grazing range and offered two salt-selenium mineral mixtures free choice The concentration of selenium in one mixture was 40 ppm (low Se group) and the other 80 ppm (high Se group) These levels represent 2 and 4 times the maximal level currently permitted by FDA

Blood selenium concentrations (Figure 1) were determined on each animal at weekly intervals initially then at monthy intervals Intake of the salt-selenium mixture was also measured at monthly intervals to obtain total group mean intake of selenium

Blood selenium concentration rose from the initial concentration of 0035 ~gml to a maxima of approximately 0225 ~gm1 in the high group and 0150 ~gm1 in the low group at about 12 weeks Then maximal concentrations are within the range of normality and in no way indicate selenium toxicity

Intake of the salt-selenium mixture was not well correlated with blood concentration of se1eniUffl

Then data indicate that the FDA maximal level of 20 ppm selenium in salt supplements is conservative and may be ineffectual in areas of selenium deficiency There was no significant difference in the weight of the cows at the time the calves were weaned - low group 487 ~ 48 kg high group - 481 ~ 57 kg

SlJotMARY OF COMMENTS

The foothills of California offer an ideal place for people

to pursue farming Farming in the tradi tional sense family cerltered

labor interlsive small machinery oriented conservation minded small

Hopefully the U C Sierra Foothill Range Field Station will accept

and meet the challenge of providing research and information appropriate

to the fledgling development of a foothill agriculture ethic in which

the quality of food and living is paramount Projects of this nature

are few in the 1981 annual report Possibly we can make II greeter

contribution to foothill farming in the future

6 Progress Report (Progress during report period toward reaching objectives of this research)

An evaluation was undertaken of the necessity for vitamin A supplementation of range cows

A group of 12 cows were grazed on range without access to irrigated pasture or B carotene supplements At monthly intervals over the past year liver biopsies were performed and blood collected for carotene and vitamin A determinations

At no time did circulating vitamin A concentrations indicate that supplementation was necessary

The relationship between hepatic reserves and circulating levels is being examined

There was no research activity at the SFRFS under this project during 1981 Two related studies were conducted at Davis as Masters Degree thesis research problems using plants of Ladino clover strawberry clover orchardgrass and perennial ryegrass co11eete from pasture fields at the SFRFS

1 In the first study- plant shoot root and nodule morphological and yield response

to applied nitrogen (0 60 120 and 180 kgha) and to variation in soil (rootnodule zone) temperature variations (with emphasis on the higher-than-optimal temperatures of mid-summer) were studied using micro-swards established in containers measuring 35 em x 3 em x 285 em (ht width depth)

In the second stud~ plants of Ladino clover and strawberry clover grown in a controlled environment facility were subjected to one two or three short-term watershystress cycles (wilting for 10 day-light hours followed by restoration of soil moisture) Responses were measured as alterations in plant growth (both shoot and root) and by use 0

The objectives of this research were outlined in the 1980 report Many of the same trends observed in 1980 were repeated in 1981 Body weights of the cows were positively related to level of supplementation

(Table 1) The greatest effect was observed at the start of the breeding season where the difference between the unsupplemented and 25 times supplemented cows was nearly 100 kg

Weaning weight of the calves (Table 2) reflected the plane of nutrition of the cows Although weaning weights were enhanced by supplementation the largest differences in body weights occurred at the times the dams were mated Body weights of the calves reflected differential milk production of the cows

As in the previous year birth weight of the calves was not affected by plane of nutrition of the cows

6 Progress Report (Progress during report period toward reaching objectives of this research)

The major objectives of this research with Hereford cattle are (1) to determine if individual differences in mounting frequency by juvenile males correlate with individual differences in sexual motivation and performance as adults (2) to determine the degree of correlation between sexual behaviors and other biological traits (eg aggressive behavior semen characteristics hormone levels body size scrotal circumference) (3) to determine the function of mounting exshyperience on the development of sexual behavior and (4) to determine the role of penile stimulation on the development of sexual behavior

Over the last 4 years 78 bulls have been obtained from the SFRFS herd to investigate these questions Twenty-four male calves were brought to Davis from SFRFS in May 1981 to be used in studying objective 114 No observations were made on this group at the Field Station

Prior to 1981 all of our observations on juvenile mounting (Objectives 1 and 3) were made in confined situations where estrous heifers were provided as mountingstimuli and inter-animal contacts were frequent To determine the frequency of juvenile mounting in a more typical range environment 10 male and 9 female purebredHereford calves were observed between January 13 and March 22 1981 for a total of 40 hrs (29 different days) The calves ranged in age from 48 to 102 days (x = 80 days) at the start of observation A total of 394 calf observation hours were made on the 10 bull calves in the group and 749 calf hours on all 19 calves

Relative to our studies in confinement the rate of juvenile mounting in a typical range environment is very low A total of 15 mount intentions 12 mount attempts and 6 mounts (33 mount responses) were observed during the 40 hrs of observation Except for one mount intention all of the mounting activities were exhibited by bull calves The rate of mount responses was 0084 per bull calf per hour of observation Nearly all of the mounting behaviors were observed near the feed trough following feeding of supplements Supplemental feeding was terminated on February 25th and no sexual activity was observed among calves after that date

It was concluded that the mounting experience of 2-12 to 4-12 mo juvenilecalves in a ranqe environment is very limited

CO1tinued work in the Tea Garden Plot fairly well protected from deer has show~ reasonably good resul ts for only a few coni fer~ ad hardwoods The 100St

promising at present arc Monterey pine coast redwood and varieties of Pinus halepensis (brutia and eldarica) The most promising hardwoods to date are Eucalyptus globulus camaldulensis (2 variants) urnigera and grandis

In the lower Plot near the Yuba River deer and cattle damage al1d some porcupine debarking have greatly reduced the choice of species here The above pines Arizona cypress plus possibly tamarisk aphylla and coast redwood still appear promising

The North Plot after 3 years of trial plantings versus 4 for the other plots shows promising results for only Arizona cypress Eucalyptus grandis from 2 sources and tamarisk aphylla It is too early to rate the remainj~g species over-all survival rates of which are generally low

No fertilizer tablets have been applied to any of these plots because other factors limiting growth and survival appear more Important There was no serious rodent or insect damage noted in any of the 3 plots this past year and irrigation practices have been generally good probably supplying around 3 acre feet per growing season of about 6 months

It is now planned to establish semi-commercial plots of a minimum of 112 acre for each of at least 5 of the most promising species in another area of the Sierra Field Station

Development work continued in the Campbell Field A fall-1980 seeding of a perennia grass-legume pasture mixture on the new irrigated pasture areas was successful except for parts of some fields where irrigation water (surface flow) failed to reach In general the newly-installed irrigation system performed well

The following work was done on or related to the range fertilization study being conducted on the Forbes Flll44 series fields

a Soil samples were taken from each of the 16 fields Analyses will be made for P 5 Ca Mg K and pH

b In cooperation with M B Jones (HFS) field plots were established at eight locations (4 north-facing aspects 4 south-facing) A factorial design was used to compare 4 levels of N (as urea) and 4 levels of P (as low-S concentrated superphosphate) plus an exploratory for several combinations of NPS with two replications at each locati r

c Also in cooperation with M B Jones a greenhouse pot test was set up at the Hopland Field station with rate-element combinations to match those in the field plots using soil collected at the field locations for the eight replications The pots were seeded with a mixture of sub and rose clovers together with soft chess

d M R George and W J Clawson located sites for a grazing utilization study employing 10 x 10 exclosures

e A field-scale experiment with aerial application of nitrogen (as urea) at 0 40 80 and 120 kgha rates (two fields per replication two replications per treatment) is planned for fall 1982 following evaluation of the tests described above and results of a pre-experiment calibration grazing (with steers) beginning February 1982 Roy Hull J G Morris and R E Delmas are cooperators from the Department of Animal Science

f Using Sobrante-Las Posas soil collected at the SFRFS a study of effects of levels of single superphosphate with and without N and effects of fertiizer placement on emergence growth and nodulation of sub clover was completed at Davis- bull

6 Progress Report (Progress during report period toward reaching objectives of this research)

Four pairs of 14 acre plots were established during the fall of 1979 The Blue Oak overstory of these paired plots was approximately 0 25 50 and 75 The tree overstory was removed from one set of four plots by February 15 1980 and 12 wire mesh igloo type cages were placed on all plots by December 1980 Cages were located under tree canopy (or former tree canopy) and in the open using a stratified random procedure with proportional allocation

During 1981 three successive clippings were taken from inside the wire cages to determine the total standing crop present on February 21 (early season) April 3 amp 4 (mid-season) and June 2 (late season)

Preliminary Results (1981)

Uncleared plots 25 50 and 75 overstory cover Standing crop at any season did not differ appreciably by overstory level (Fig 1) When compared with uncleared open (0 overstory cover) plots standing crop was significantly less in uncleared plots at late season but not at early and mid-season Overstory cover and standing crop are not significantly correlated for any season (Fig 2)

Cleared Plots 25 50 and 75 prior overstory cover Standing crop is positively correlated with prior overstory cover particularly when uncleared open (0 overstory cover) plots are included in the comparison (Fig 2)

Tree removal greatly increased standing crop at all three seasons of harvest for all overstory cover levels (Fig 1) When compared to uncleared plots of the same overstory cover level these increases were 100 early season 133 midshyseason and 80 late season

6 Progress Report (Progress during report period toward reaching objectives of this research)

This experiment was undertaken to assess the efficacy and safety of a salt selenium mixture for supplementing range cows

Approximately a years data have been obtained on two groups each of 19 mature Hereford cows grazing range and offered two salt-selenium mineral mixtures free choice The concentration of selenium in one mixture was 40 ppm (low Se group) and the other 80 ppm (high Se group) These levels represent 2 and 4 times the maximal level currently permitted by FDA

Blood selenium concentrations (Figure 1) were determined on each animal at weekly intervals initially then at monthy intervals Intake of the salt-selenium mixture was also measured at monthly intervals to obtain total group mean intake of selenium

Blood selenium concentration rose from the initial concentration of 0035 ~gml to a maxima of approximately 0225 ~gm1 in the high group and 0150 ~gm1 in the low group at about 12 weeks Then maximal concentrations are within the range of normality and in no way indicate selenium toxicity

Intake of the salt-selenium mixture was not well correlated with blood concentration of se1eniUffl

Then data indicate that the FDA maximal level of 20 ppm selenium in salt supplements is conservative and may be ineffectual in areas of selenium deficiency There was no significant difference in the weight of the cows at the time the calves were weaned - low group 487 ~ 48 kg high group - 481 ~ 57 kg

SlJotMARY OF COMMENTS

The foothills of California offer an ideal place for people

to pursue farming Farming in the tradi tional sense family cerltered

labor interlsive small machinery oriented conservation minded small

Hopefully the U C Sierra Foothill Range Field Station will accept

and meet the challenge of providing research and information appropriate

to the fledgling development of a foothill agriculture ethic in which

the quality of food and living is paramount Projects of this nature

are few in the 1981 annual report Possibly we can make II greeter

contribution to foothill farming in the future

An evaluation was undertaken of the necessity for vitamin A supplementation of range cows

A group of 12 cows were grazed on range without access to irrigated pasture or B carotene supplements At monthly intervals over the past year liver biopsies were performed and blood collected for carotene and vitamin A determinations

At no time did circulating vitamin A concentrations indicate that supplementation was necessary

The relationship between hepatic reserves and circulating levels is being examined

There was no research activity at the SFRFS under this project during 1981 Two related studies were conducted at Davis as Masters Degree thesis research problems using plants of Ladino clover strawberry clover orchardgrass and perennial ryegrass co11eete from pasture fields at the SFRFS

1 In the first study- plant shoot root and nodule morphological and yield response

to applied nitrogen (0 60 120 and 180 kgha) and to variation in soil (rootnodule zone) temperature variations (with emphasis on the higher-than-optimal temperatures of mid-summer) were studied using micro-swards established in containers measuring 35 em x 3 em x 285 em (ht width depth)

In the second stud~ plants of Ladino clover and strawberry clover grown in a controlled environment facility were subjected to one two or three short-term watershystress cycles (wilting for 10 day-light hours followed by restoration of soil moisture) Responses were measured as alterations in plant growth (both shoot and root) and by use 0

6 Progress Report (Progress during report period toward reaching objectives of thi 5 research)

The objectives of this research were outlined in the 1980 report Many of the same trends observed in 1980 were repeated in 1981 Body weights of the cows were positively related to level of supplementation

(Table 1) The greatest effect was observed at the start of the breeding season where the difference between the unsupplemented and 25 times supplemented cows was nearly 100 kg

Shrunk all others full body weight

Weaning weight of the calves (Table 2) reflected the plane of nutrition of the cows Although weaning weights were enhanced by supplementation the largest differences in body weights occurred at the times the dams were mated Body weights of the calves reflected differential milk production of the cows

As in the previous year birth weight of the calves was not affected by plane of nutrition of the cows

6 Progress Report (Progress during report period toward reaching objectives of this research)

The major objectives of this research with Hereford cattle are (1) to determine if individual differences in mounting frequency by juvenile males correlate with individual differences in sexual motivation and performance as adults (2) to determine the degree of correlation between sexual behaviors and other biological traits (eg aggressive behavior semen characteristics hormone levels body size scrotal circumference) (3) to determine the function of mounting exshyperience on the development of sexual behavior and (4) to determine the role of penile stimulation on the development of sexual behavior

Over the last 4 years 78 bulls have been obtained from the SFRFS herd to investigate these questions Twenty-four male calves were brought to Davis from SFRFS in May 1981 to be used in studying objective 114 No observations were made on this group at the Field Station

Prior to 1981 all of our observations on juvenile mounting (Objectives 1 and 3) were made in confined situations where estrous heifers were provided as mountingstimuli and inter-animal contacts were frequent To determine the frequency of juvenile mounting in a more typical range environment 10 male and 9 female purebredHereford calves were observed between January 13 and March 22 1981 for a total of 40 hrs (29 different days) The calves ranged in age from 48 to 102 days (x = 80 days) at the start of observation A total of 394 calf observation hours were made on the 10 bull calves in the group and 749 calf hours on all 19 calves

Relative to our studies in confinement the rate of juvenile mounting in a typical range environment is very low A total of 15 mount intentions 12 mount attempts and 6 mounts (33 mount responses) were observed during the 40 hrs of observation Except for one mount intention all of the mounting activities were exhibited by bull calves The rate of mount responses was 0084 per bull calf per hour of observation Nearly all of the mounting behaviors were observed near the feed trough following feeding of supplements Supplemental feeding was terminated on February 25th and no sexual activity was observed among calves after that date

It was concluded that the mounting experience of 2-12 to 4-12 mo juvenilecalves in a ranqe environment is very limited

Progress Report (Progress during report period toward reaching objectives of this research)

To repeat the mejor- objective of this experimental tree-planting pogrC1m is to develop species and cultural practices which can be used to improve he retJi~ to the h1d-oltl1er Ild al the same time the quality of the site a1d i S poductive capacity for- multiple uses

CO1tinued work in the Tea Garden Plot fairly well protected from deer has show~ reasonably good resul ts for only a few coni fer~ ad hardwoods The 100St

promising at present arc Monterey pine coast redwood and varieties of Pinus halepensis (brutia and eldarica) The most promising hardwoods to date are Eucalyptus globulus camaldulensis (2 variants) urnigera and grandis

In the lower Plot near the Yuba River deer and cattle damage al1d some porcupine debarking have greatly reduced the choice of species here The above pines Arizona cypress plus possibly tamarisk aphylla and coast redwood still appear promising

The North Plot after 3 years of trial plantings versus 4 for the other plots shows promising results for only Arizona cypress Eucalyptus grandis from 2 sources and tamarisk aphylla It is too early to rate the remainj~g species over-all survival rates of which are generally low

No fertilizer tablets have been applied to any of these plots because other factors limiting growth and survival appear more Important There was no serious rodent or insect damage noted in any of the 3 plots this past year and irrigation practices have been generally good probably supplying around 3 acre feet per growing season of about 6 months

It is now planned to establish semi-commercial plots of a minimum of 112 acre for each of at least 5 of the most promising species in another area of the Sierra Field Station

6 Progress Report (Progress during report perio toward reaching objectives of this research)

Development work continued in the Campbell Field A fall-1980 seeding of a perennia grass-legume pasture mixture on the new irrigated pasture areas was successful except for parts of some fields where irrigation water (surface flow) failed to reach In general the newly-installed irrigation system performed well

The following work was done on or related to the range fertilization study being conducted on the Forbes Flll44 series fields

a Soil samples were taken from each of the 16 fields Analyses will be made for P 5 Ca Mg K and pH

b In cooperation with M B Jones (HFS) field plots were established at eight locations (4 north-facing aspects 4 south-facing) A factorial design was used to compare 4 levels of N (as urea) and 4 levels of P (as low-S concentrated superphosphate) plus an exploratory for several combinations of NPS with two replications at each locati r

c Also in cooperation with M B Jones a greenhouse pot test was set up at the Hopland Field station with rate-element combinations to match those in the field plots using soil collected at the field locations for the eight replications The pots were seeded with a mixture of sub and rose clovers together with soft chess

d M R George and W J Clawson located sites for a grazing utilization study employing 10 x 10 exclosures

e A field-scale experiment with aerial application of nitrogen (as urea) at 0 40 80 and 120 kgha rates (two fields per replication two replications per treatment) is planned for fall 1982 following evaluation of the tests described above and results of a pre-experiment calibration grazing (with steers) beginning February 1982 Roy Hull J G Morris and R E Delmas are cooperators from the Department of Animal Science

f Using Sobrante-Las Posas soil collected at the SFRFS a study of effects of levels of single superphosphate with and without N and effects of fertiizer placement on emergence growth and nodulation of sub clover was completed at Davis- bull

6 Progress Report (Progress during report period toward reaching objectives of this research)

This is the third year in which numbers of infective parasite larvae on pasture has been assessed by placing 2 worm-free tracer calves on pasture at monthly intervals Since this is only one of several locations where these studies are being conducted not all laboratory analyses have been completedNevertheless studies over the three year period demonstrates the occurrence of infective nematode larvae on pastures is repetitive and predictable The season for the occurrence of disease producing numbers of various species differs little in such diverse regions as the San Joaquin Valley (Elk Grove) the East Slope of the Sierras (Susanville) or the Sierra Foothills (UCSFR) This studycorroborates the newly emerging concepts of safe and unsafe grazing periods The application of data from this study can be utilized in managerial decisions and thus in Integrated Pest (parasite) Control programs It is planned that trials designed to establish the value of these IPC programs will be initiated at several locations including UCSFR during the 1981-82 year

6 Progress Report (Progress during report period toward reaching objectives of this research)

Four pairs of 14 acre plots were established during the fall of 1979 The Blue Oak overstory of these paired plots was approximately 0 25 50 and 75 The tree overstory was removed from one set of four plots by February 15 1980 and 12 wire mesh igloo type cages were placed on all plots by December 1980 Cages were located under tree canopy (or former tree canopy) and in the open using a stratified random procedure with proportional allocation

During 1981 three successive clippings were taken from inside the wire cages to determine the total standing crop present on February 21 (early season) April 3 amp 4 (mid-season) and June 2 (late season)

Preliminary Results (1981)

Uncleared plots 25 50 and 75 overstory cover Standing crop at any season did not differ appreciably by overstory level (Fig 1) When compared with uncleared open (0 overstory cover) plots standing crop was significantly less in uncleared plots at late season but not at early and mid-season Overstory cover and standing crop are not significantly correlated for any season (Fig 2)

Cleared Plots 25 50 and 75 prior overstory cover Standing crop is positively correlated with prior overstory cover particularly when uncleared open (0 overstory cover) plots are included in the comparison (Fig 2)

Tree removal greatly increased standing crop at all three seasons of harvest for all overstory cover levels (Fig 1) When compared to uncleared plots of the same overstory cover level these increases were 100 early season 133 midshyseason and 80 late season

Efficacy of sall as a vehicle for selenium supplementatio~

4 Project Leader J G Morri 5 1 5 bull Period Covered QL sectL - 1L A by this Report mo yr mo yr

6 Progress Report (Progress during report period toward reaching objectives of this research)

This experiment was undertaken to assess the efficacy and safety of a salt selenium mixture for supplementing range cows

Approximately a years data have been obtained on two groups each of 19 mature Hereford cows grazing range and offered two salt-selenium mineral mixtures free choice The concentration of selenium in one mixture was 40 ppm (low Se group) and the other 80 ppm (high Se group) These levels represent 2 and 4 times the maximal level currently permitted by FDA

Blood selenium concentrations (Figure 1) were determined on each animal at weekly intervals initially then at monthy intervals Intake of the salt-selenium mixture was also measured at monthly intervals to obtain total group mean intake of selenium

Blood selenium concentration rose from the initial concentration of 0035 ~gml to a maxima of approximately 0225 ~gm1 in the high group and 0150 ~gm1 in the low group at about 12 weeks Then maximal concentrations are within the range of normality and in no way indicate selenium toxicity

Intake of the salt-selenium mixture was not well correlated with blood concentration of se1eniUffl

Then data indicate that the FDA maximal level of 20 ppm selenium in salt supplements is conservative and may be ineffectual in areas of selenium deficiency There was no significant difference in the weight of the cows at the time the calves were weaned - low group 487 ~ 48 kg high group - 481 ~ 57 kg

SlJotMARY OF COMMENTS

The foothills of California offer an ideal place for people

to pursue farming Farming in the tradi tional sense family cerltered

labor interlsive small machinery oriented conservation minded small

Hopefully the U C Sierra Foothill Range Field Station will accept

and meet the challenge of providing research and information appropriate

to the fledgling development of a foothill agriculture ethic in which

the quality of food and living is paramount Projects of this nature

are few in the 1981 annual report Possibly we can make II greeter

contribution to foothill farming in the future
