Abstract

Expected progeny differences, or EPD, have become widely accepted by beef cattle producers. Commonly available EPD include birth weight, weaning weight, yearling weight, milk and total maternal. Using these EPD, producers may tailor their breeding herds to levels of these traits appropriate to their environment and management. One complaint about the traditional EPD, however, is they do not address reproductive performance. The stayability EPD predict the probability that females will remain in
 production until a specific age, and may provide genetic evaluations for reproductive performance in beef cows.
