The available Expected Progeny Difference (EPD) numbers are included in the catalog and were current as of 2/9/23, as reported by the American Angus Association or American Simmental Association. EPDs are predictions of how future progeny are expected to perform in each of the traits listed, as compared to the progeny of a breed average bull. EPDs ranking in the top 25% of their breed contemporaries are footnoted.

PRODUCTION/MATERNAL EPDs:

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 ease with which a sire’s calves will be born when he is bred to first-calf heifers.

Birth Weight (BW), expressed in pounds, is a predictor of a sire’s ability to transmit birth weight to his progeny compared to that of other sires.

Weaning Weight (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.

Yearling Weight (YW) expressed in pounds, is a predictor of a sire’s ability to transmit yearling growth compared to that of other sires.

Scrotal Circumference (SC), expressed in centimeters, is a predictor of the difference in transmitting ability for scrotal size compared to that of other sires.

Docility (Doc), is expressed as a difference in yearling cattle temperament, with a higher value indicating more favorable docility. It predicts the average difference of progeny from a sire in comparison with another sire’s calves.

Heifer Pregnancy (HP) EPDs are designed to characterize differences among sires for daughters’ heifer pregnancy. A higher EPD sire would be expected to have daughters with a greater probability or chance of becoming pregnant during a normal breeding season than a sire with a lower EPD.

Calving Ease Maternal (CEM) is expressed as a difference in percentage of unassisted births, with a higher value indicating greater calving ease in first-calf daughters. It predicts the average ease with which a sire’s daughters will calve as first-calf heifers when compared to daughters of other sires.

Maternal Milk (Milk) is a predictor of a sire’s genetic merit for milk and mothering ability as expressed in his daughters compared to daughters of other sires. It is that part of a calf’s weaning weight attributed to milk and mothering ability.

CARCASS EPDs:

The genetic evaluation produces a single set of EPDs for carcass weight, marbling score, Ribeye area and fat thickness. The units of measure are in carcass trait format and analyzed on an age-constant basis.

Carcass Weight (CW), expressed in pounds, is a predictor of the differences 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 USDA marbling 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.

ANGUS $VALUE INDEXES

$Value indexes are multi-trait selection indexes to assist beef producers by adding simplicity to genetic selection decisions. $Values are reported in dollars per head, where a higher value is more favorable. The $Value is an estimate of how future progeny of each sire are expected to perform, on average, compared to progeny of other sires in the database if the sires were randomly mated to cows and if calves were exposed to the same environment.

Maternal Weaned Calf Value ($M): Predicts profitability differences from conception to weaning with the underlying breeding objective assuming that individuals retain their own replacement females within herd and sell the rest of the cull female and all male progeny as feeder calves. The model assumes commercial producers will replace 25% of their breeding females in the first generation and 20% of their breeding females in each subsequent generation. Traits included: CED, CEM, WW, Milk, HP, Doc, Mature Cow Weight, Claw Set and Foot Angle.

Weaned Calf Value ($W): Predict profitability differences in progeny due to genetics from birth to weaning. The underlying objective being producers will retain 20% of the female progeny as replacements and sell the rest of the cull females and their male counterparts as feeder calves. Traits included are: BW, WW, Milk, Mature Cow Weight.

Feedlot Value ($F): Predicts profitability differences in progeny due to genetics for postweaning feedlot merit compared to the progeny of other sires

Grid Value ($G): Predicts profitability differences in progeny due to genetics for carcass grid merit compared to progeny of other sires.

Beef Value ($B): A terminal index to predict profitability differences in progeny due to genetics for postweaning and carcass traits.

Combined Value ($C): An index which includes all traits that make up both Maternal Weaned Calf Value ($M) and Beef Value ($B).
