Term Definition

 (Expected progeny difference) Estimates the difference in the expected performance of the offspring of an individual for a specific trait, given in units of that trait. The difference between two EPDs from two different animals would tell you on average the expected difference between their offspring. For instance, if Bull A has a weaning weight EPD of 60 and Bull B has a weaning weight EPD of 50, on average Bull A's calves will weigh 10 pounds more at weaning than Bull B's calves.
