Milk EPD is a prediction of weaning weight differences due to milk and maternal ability of the dam. For a sire, the Milk EPD predicts the maternal ability of his daughters expressed in pounds of calf weaned. Milk EPD s do not specifically predict pounds of milk produced, but pounds of calf weaned due to maternal production of the dam. It has no accuracy value since it is simply a combination of two other EPD s. Scrotal EPD is based on a bull's 365-day adjusted yearling scrotal circumference measured in centimeters.
Scrotal circumference is directly related to a bull's fertility and reproductive performance.
Yearling weight EPD based on adjusted 365-day yearling weight. Yearling weight EPD is related to overall growth prior to and after the yearling period. Breeding cattle with higher REA EPD s should produce slaughter progeny with less external fat thickness. Ribeye Area EPD is an adjusted 365-day carcass ribeye area measure based on ultrasound measurements of live yearling cattle. Breeding cattle with higher REA EPD s should produce slaughter progeny with more muscle.
