Calves are the future of dairy herd
It is said that “good animals are raised, not purchased”.
Raising calves is by far the most difficult operation in a dairy farming
enterprise
Mortality rate of calf is very high (15-35 %)
Successful calf growth & health- good management & nutrition of young
calf
For maintaining efficiency of production, 20 - 25% of cows should be
replaced with heifer-cows
Introduction
![Page 3: FEEDING OF CALF](https://reader031.fdocuments.us/reader031/viewer/2022022604/62183f6a7ee69d1515690f71/html5/thumbnails/3.jpg)
Cont.
Well grown, vigorous animals are usually those that have had
excellent care from birth
Undersized calves may be due to lack of knowledge of the
principles of scientific feeding and practices of calf rearing
Scientific rearing of calf is necessary
Higher the plane of nutrition, earlier is the onset of puberty &
quicker the return of capital

Cont.
Feed cost : > 60% of total expenditure
Effective way of minimizing the high feed costs of calf rearing
through early weaning early rumen development
reduced milk feeding milk replacers
Whole milk would be the most natural feed for calves, but
due to its high cost, it is well replaced by calf milk replacer
(CMR)

Practical feeding of calf
May be divided into fallowing category
feeding during last trimester of pregnancy
Pre-ruminant period- before rumen development
post ruminant period- after rumen development

feeding during last trimester of pregnancy
Nourishment of calf should be taken care much before it is born
Extra nutrient should be given during last trimesterof gestation
Expectant dam should be provided with 15-20 kg green fodder
daily – to make colostrum rich in vit A
If green not offered, calf should be given 10000 IU vit A in its 1st
feed
Thereafter dosage may be 1000-2000 IU daily

Pre-ruminant period- 0-3 month
Feeding during pre-ruminant stage can be divided
into fallowing steps
1. Colostrum feeding
2. Whole milk feeding
3. Skim milk
4. Calf starter
5. Milk replacer
6. Roughase – hay

Importance of Colostrum feeding
Provide passive immunity
Laxative effect
Antitrypsin action
Excellent source of Vit A,D, & E
Excellent economic diet for both the neonates &
older calves
Contain antibacterial substances- lactoferrin,
lactoperoxidase & lysozyme

Milk replacer
High cost of milk
Competition with the humans for food
Convenience and economics – drive the increase in use of milk replacers
Increased use of milk replacers – continue as long as the price differential between milk and milk replacers remains
23
Need for milk replacer feeding:
![Page 24: FEEDING OF CALF](https://reader031.fdocuments.us/reader031/viewer/2022022604/62183f6a7ee69d1515690f71/html5/thumbnails/24.jpg)
Made from byproducts of the dairy industry.
Whey proteins form the major protein sources in milk
replacers, containing only milk protein.
Whey is usually much cheaper than other milk proteins
such as casein and skim milk.
24
![Page 25: FEEDING OF CALF](https://reader031.fdocuments.us/reader031/viewer/2022022604/62183f6a7ee69d1515690f71/html5/thumbnails/25.jpg)
The use of high quality, lower cost ingredients makes milk
replacer a more economic choice than whole milk.
Diseases can be transmitted from cow to calf through
unpastuerized milk.
25
![Page 26: FEEDING OF CALF](https://reader031.fdocuments.us/reader031/viewer/2022022604/62183f6a7ee69d1515690f71/html5/thumbnails/26.jpg)
Goals of milk replacer feeding program
Achieve optimum growth rate,
Minimize health disorders,
Stimulate and optimize rumen development,
Minimize the cost of feeding the young
calves.

Essential properties of milk replacers:
• Nutritiously adequate.
• Easy to use, palatable and economical.
• Properly formulated
• Achieve comparable weight gain to that of whole milk.
• Supply sufficient energy, high quality protein, minerals and vitamins
27
![Page 28: FEEDING OF CALF](https://reader031.fdocuments.us/reader031/viewer/2022022604/62183f6a7ee69d1515690f71/html5/thumbnails/28.jpg)
• Low in fibre , contain minimum of 22% total protein.
• Contain 10-20% fat.
• Ingredients should make a homogeneous mixture
with water.
• Must be good in consistency and remain in
suspension for some time for calf consumption.

Calf starter
It is a solid feed consisting of ground grains, oil cakes, animal protein
supplements & brans fortified with vitamins, minerals & antibiotic feed
supplements
It should contain 18%DCP OR 23-26 % CP & 75% TDN
Constituent can be altered acc to availability of feeds
Remember that calf does not grow on % of protein but rather on the amount
of protein & other nutrients
31
![Page 32: FEEDING OF CALF](https://reader031.fdocuments.us/reader031/viewer/2022022604/62183f6a7ee69d1515690f71/html5/thumbnails/32.jpg)
Essential properties of calf starter
Nutritiously adequate.
Easy to use, palatable and economical.
• Properly formulated
Highly digestible
Supply sufficient energy, high quality protein, minerals and
vitamines
Low in fibre -less than 7% fiber because low level of fibrous
material benefits starter intake and calf growth

Importance of starter
Improves the health of calves
Reduces the stress of weaning
Reduces the growth depressing factors
It reduces the chances of diarrhea in calves
Improve immune system
Help in rumen development

Hay
Hay is also important to a calf’s diet
Start giving long, dry hay to calves at about two months of
age
Hay helps the calf’s stomach grow
It also gives the calf extra energy
Feeding dry feed is cheaper than milk
