EPD Information
Performance EPDS :
Calving Ease Direct (CED or CE): The Calving Ease Direct EPD measure the ease at which a bull's calves will be born. This EPD is expressed as a difference in percentage of unassisted births, with a higher value indicating greater calving ease 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.
Maternal EPDS:
Heifer Pregnancy (HP): 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. Calving Ease Maternal (MCE or CEM): 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. Milk (MILK): A predictor of a sire's genetic merit for milk and mothering ability as expressed in his daughters compared to daughters of other sires. In other words, it is that part of a calf's weaning weight attributed to milk and mothering ability.
Mature Weight EPD (MW): Expressed in pounds, is a predictor of the difference in mature weight of daughters of a sire compared to the daughters of other sires.
Stayability and Functional Longevity (STAY or FL ): An indicator of longevity and sustained fertility of a bull's daughters in the cow herd. A higher value is more desirable.
