NEW TOOLS FOR COMMERICAL USERS OF ANGUS GENETICS
HEIFER SELECTION DECISION POINTS
Select heifers with most earning potential
Select sires to produce the best heifer calf crop
Select the best sires to breed to heifers (A.I. and/or natural)
TraitCorrelations (%GV) for GE-EPDs

Maternal Traits – GE-EPD accuracy equals an average of 14 daughters’ information
Growth & Efficiency – GE-EPD accuracy equals an average of 17 progeny with performance data
Carcass Traits – GE-EPD accuracy equals an average of 10 progeny with carcass data
GE-EPDS AND ACCURACY POWERED BY HD 50K1
TRADITIONAL HEIFER SELECTION
WHICH ONESWILL MAKE THE MOST PROFITABLE COWS?
• Visual • Earliest Born• Reproductive Tract Score• Dam’s Production / Soundness
GENEMAX ADVANTAGE FEATURES
1 Three GeneMax Advantage economic index scores that encompass maternal, growth, efficiency & carcass traits
2SMART Outlier Reporting – identifies extremes for cow costs, docility, tenderness and marbling (top/bottom animals)
3 Sire Match to your Zoetis HD 50K-tested Angus bull battery
GENEMAX ADVANTAGE INDEX SCORES
Revenue/cost assumptions consistent with Angus indexes 2 – 8
Cow Advantage ScoreConception to Weaning
Feeder Advantage Score
Weaning to CAB carcass
Total Advantage ScoreConception to Carcass
ECONOMIC INDEX SCORES
Describes Differences in Net Return (1 - 100, higher score better, average = 50)
Cow Advantage
Cow productivity from heifer pregnancy, calving ease, milk, cow size and growth transmitted to calf
Feeder Advantage
Postweaning progeny growth, feed intake & carcass merit on CAB grid. Complements GeneMax Focus gain & grade
Total Advantage
Total genetic contribution for productivity from conception to CAB carcass (Cow & Feeder)
TOTAL ADVANTAGE SCORE – RELATIVE TRAIT CONTRIBUTIONS
Maternal
Heifer Pregnancy,Calving Ease TotalMaternal, Milk &Cow Size

Carcass Merit

SMART OUTLIER REPORTING
Cow Cost fromSize and Milk
Identifies highest-cost cows from
extremes in size & milk
Bottom 5%
Docility
Identifies genetic
potential for less desirable temperament
Bottom 5%
Marbling
Identifies low and high marbling
Top & Bottom 25%
Tenderness
Identifies unfavorable
outliers
Bottom 5%

USING GENEMAX ADVANTAGE FOR DECISION-MAKING
Registered, transferred, Black Angus sire - ideally Zoetis HD 50K tested
≥ 50% Black Angus Dam
CAN I USE GENEMAX ADVANTAGE FOR NON-ANGUS COMMERCIAL FEMALES?
GeneMax Advantage is for commercial females that are 75% or greater Black Angus breed composition.
HEIFER SELECTION DECISIONS
• Test heifers at weaning or bangs vaccination• Rank and select replacements on Total Advantage Score• Exclude outliers for cow cost and/or temperament • Allocate to A.I. and/or natural service sires
– Complementary mating (balance Cow & Feeder Advantage Scores – correct tenderness & marbling outliers)
– Minimize Inbreeding

FREQUENTLY ASKED QUESTIONS
HOW DO I ORDER GENEMAX ADVANTAGE TESTS?
1. Log in to the AAA/GeneMax customer site for information and to order collectors and tests:
• Available at www.angusonline.org/genemax/logon.aspx
2. Obtain sample collectors• Blood cards are available from the American Angus Association or Zoetis Genetics• Allflex Tissue Collectors are only available through Zoetis Genetics
3. Collect samples• Demonstration videos are available on the Zoetis Genetics YouTube channel, as
well as via links on the AGI/AAA and CAB websites
4. Send samples to:Angus Genetics Inc.
3201 Frederick Ave.
Saint Joseph, MO 64506
Phone: 816-383-5100
WHAT TYPES OF GENETIC SAMPLES ARE ACCEPTABLE FOR GENEMAX ADVANTAGE?
• Blood or tissue samples• Blood cards are available from
Angus Genetics Inc or Zoetis Genetics
• Allflex tissue collectors are only available from Zoetis Genetics
• Do not use Allflex tissue collectors for GeneMax Focus or HD 50K for Angus
HOW LONG DOES IT TAKE TO GET RESULTS?
• 3 – 4 weeks from the time samples and order forms are received to available results
• An email will alert you when the report is available on the AGI website
WHAT IF MY BULLS ARE NOT ZOETIS HD 50K TESTED?
• Angus bulls must be Zoetis HD 50K tested to enable the Sire Match feature for tested progeny
• Buy registered, HD 50K tested Angus bulls and request that they be transferred to you to enable seamless Sire Match assignment
• You may have your registered Angus bulls tested with Zoetis HD 50K either prior to or after progeny are GeneMax tested
TODAY’S HEIFER ECONOMICS
Adapted from Hughes, H., 2012. Expansion arithmetic, BEEF Magazine, pp. 12-13.
Heifers retained in 2014 will be among the most expensive commercial replacements in history.
Replacement females will need to produce and wean more than 4 calves to return a profit.
