AMERICANANGUS ASSOCIATION SELECTIONTOOLS

We’re committed to “Driving the science of better breeding” by providing youwith the American Angus Association selection tools but we’re doing sowithmore reliability and predictability through genomically enhanced EPDs.

All lotswith the above designation offer you TWO IMPORTANT ADVANTAGES: # 1 They have been parent verified to ensure pedigree accuracy. You can place 100%confidence that the genetics you’re purchasing are accurately represented. Genomic test results have already been factored into their individual EPDs providing youwith higher accuracy EPDs that are the equivalent of that individual already having produced and recorded 8-33 calves depending on the trait measured. For commercial and seedstock producers that’s valuable insight for more accurate selection, easier identification of genetic outliers andmore reliability and predictability for genetic progress. # 2

Calving Ease Direct (CED) is expressed as a difference in percentage of unassisted births, with a higher value indicating greater calving ease in first-calf heifers. It predicts the average difference in easewithwhich a sire’s calveswill be bornwhen he is bred to first-calf heifers. BirthWeight EPD (BW) expressed in pounds, is a predicator of a sire’s ability to transmit birthweight to his progeny compared to that of other sires. WeaningWeight EPD (WW) expressed in pounds, is a predictor of a sire’s ability to transmit weaning growth to his progeny compared to that of other sires. For example, you can expect progeny froma sirewith a 60WW EPD toweigh 20 lbs heavier on average at weaning than progeny froma sirewith a 40WWEPD. YearlingWeight EPD (YW) expressed in pounds, is a predictor of a sire’s ability to transmit yearling growth to his progeny compared to that of other sires. Scrotal Circumference EPD (SC) expressed in centimeters, is a predictor of the difference in transmitting ability for scrotal size compared to that of other sires. Docility (DOC) expressed as a difference in yearling cattle temperament,with a higher value indicatingmore favorable docility. It predicts the average difference of progeny froma sire in comparisonwith another sire’s calves. In herdswhere temperament problems are not an issue, this expected differencewould not be realized. Heifer Pregnancy (HP) is a selection tool to increase the probability or chance of a sire’s daughters becoming pregnant as first-calf heifers during a normal breeding season. A higher EPD is themore favorable direction and the EPD is reported in percentage units. Maternal Milk EPD (Milk) is a predictor of a sire’s geneticmerit for milk andmothering ability as expressed in his daughters as compared to daughters of other sires. In other words, it is that part of a calf’sweaning weight attributed tomilk andmothering ability. CarcassWeight EPD (CW) expressed in pounds, is a predictor of the difference in hot carcass weight of a sire’s progeny compared to progeny of other sires. Marbling EPD (Marb) expressed as a fraction of the difference in USDAmarbling score of a sire’s progeny compared to progeny of other sires. Ribeye Area EPD (RE) expressed in square inches, is a predictor of the difference in ribeye area of a sire’s progeny compared to progeny of other sires.

Maternal Weaned Calf Value ($M) an index, expressed in dollars per head, predicts profitability differences fromconception toweaningwith the underlying breeding objective assuming that individuals retain their own replacement femaleswithin herd and sell the rest of the cull female and all male progeny as feeder calves. Themodel assumes commercial producerswill replace 25%of their breeding females in the first generation and 20%of their breeding females in each subsequent generation. Traits included are as follows: calving ease direct, calving easematernal,weaningweight,milk, heifer pregnancy, docility,mature cowweight, clawset and foot angle. Weaned Calf Value ($W) an index value expressed in dollars per head, is the expected average difference in future progeny performance for preweaning merit. $W includes both revenue and cost adjustments associatedwith differences in birthweight,weaning direct growth,maternal milk andmature cowsize. Feedlot Value ($F) an index value expressed in dollars per head, is the expected average difference in future progeny performance for postweaningmerit compared to progeny of other sires. Grid Value ($G) an index value expressed in dollars per head, is the expected average difference in future progeny performance for carcass grid merit compared to progeny of other sires. Beef Value ($B) an index value expressed in dollars per head, is the expected average difference in future progeny performance for postweaning and carcass value compared to progeny of other sires. Combined Value ($C) an index, expressed in dollars per head,which includes all traits that make up bothMaternal Weaned Calf Value ($M) and Beef Value ($B) with the objective that commercial producerswill replace 20%of their breeding females per year with replacement heifers retainedwithin their own herd. The remaining cull heifer and steer progeny are then assumed to be sent to the feedlot where the producers retain ownership of those cattle and sell themon a quality-based carcassmerit grid. Expected progeny differences (EPDs) directly influencing a combined index: calving ease direct (CED) andmaternal (CEM),weaningweight (WW), yearlingweight (YW),maternal milk (Milk), heifer pregnancy (HP), docility (DOC),mature cowweight (MW), foot angle (Angle), clawset (Claw), drymatter intake (DMI),marbling (Marb), carcassweight (CW), ribeye area (RE) and fat thickness (Fat).
