AMERICAN ANGUS ASSOCIATION SELECTION TOOLS Expected Progeny Difference (EPD), is the prediction of how future progeny of each animal are expected to perform relative to the progeny of other animals listed in the database. EPDs are expressed in units of measure for the trait, plus or minus. Interim EPDs may appear on young animals when their performance has yet to be incorporated into the American Angus Association National Cattle Evaluation (NCE) procedures. This EPD will be preceded by an “I”, and may or may not include the animal’s own performance record for a particular trait, depending on its availability, appropriate contemporary grouping, or data edits needed for NCE.
PRODUCTION Calving Ease Direct (CED) , 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 to his progeny compared to that of other sires. Scrotal Circumference (SC), expressed in centimeters, is a predictor of the difference in transmitting scrotal size compared to that of other sires. MANAGEMENT Claw Set (Claw) , expressed in units of claw-set score, a lower EPD is more favorable, indicating a sire will produce progeny with more symmetrical, even and appropriately spaced toes compared to another sire. Foot Angle (Angle) , expressed in units of foot-angle score, a lower EPD is more favorable, indicating a sire will produce progeny with an angle closer to 45 degrees at the pastern and appropriate toe length and heel depth compared to another sire. Docility (DOC), expressed as a difference in yearling cattle temperament, with a higher value indicating more favorable docility in a sire’s offspring compared to another sire. MATERNAL 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 the more favorable direction, and the EPD is reported in percentage units. Maternal Milk (Milk), expressed in pounds of calf weaned, is a predictor of a sire’s genetic merit for milk and mothering ability in his daughters. In other words, it is the part of the calf’s weaning weight attributes to milk and mothering ability. CARCASS 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 (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 (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.
Fat Thickness EPD (Fat), expressed in inches, is a predictor of the differences in external fat thickness at the 12th rib (as measured between the 12th and 13th ribs) of a sire’s progeny compared to progeny of other sires. $VALUE INDEXES $Value Indexes, expressed in dollars per head, are multi-trait selection indexes where a higher value suggests more profit. The $Value is an estimate of how future progeny of each sire are expected to perform, on average, compared to progeny of other sires if sires were randomly mated to cows and if calves were exposed to the same environment. Maternal Weaned Calf Value ($M) , expressed in dollars per head, predicts profitability differences in progeny due to genetics from conception to weaning by decreasing mature cow size and improving docility, foot structure and fertility while maintaining weaning weights consistent with today’s production. Weaned Calf Value ($W) , expressed in dollars per head, provides the expected difference in future progeny pre-weaning performance from birth to weaning. Energy Value ($EN) , expressed in dollar savings per cow per year with a larger value being more favorable. It assesses differences in cow energy requirements, due to maternal milk and mature cow size. Feedlot Value ($F) , expressed in dollars per head, is the expected average difference in future progeny performance for post-weaning feedlot merit (growth and feed efficiency) compared to progeny of other sires assuming producers retain ownership of cattle through the feedlot phase and sell on a carcass-weight basis. Grid Value ($G) , expressed in dollars per carcass, is the expected average difference in future progeny performance for carcass grid merit, including quality and yield grade attributes, compared to progeny of other sires. Beef Value ($B) , expressed in dollars per carcass, represents the expected average differ- ences in the progeny post-weaning performance and carcass value compared to progeny of other sires. This index assumes commercial pro ducers wean all male and female progeny, retain ownership of these animals through the feedlot and sell on a carcass merit grid. Combined Value ($C), expressed in dollars per head, which includes all traits that make up both Maternal Weaned Calf Value ($M) and Beef Value ($B) with the objective that commercial producers will replace 20% of their breeding females per year with replacement heifers retained within 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 them on a quality-based carcass merit grid.
