[QUOTE="simme, post: 1675855, member: 40418"] Joe Davis' father was the principal of my school growing up and we went to the same church. Don't know if that qualifies me to respond or not. EPD's are a tool to predict performance/quality. EPD's also have an associated accuracy for each cow and trait that can help you decide how much you should trust the number for that cow. If your cows are commercial non-registered animals, their EPD's are initially assigned by the ASA based solely of breed composition. Say you purchase a black baldy cow of undocumented parentage and enroll her in the ASA THE program. You state that she if 1/2 Hereford and 1/2 Angus since that may be all you know or think you know about the genetics. You don't know the specific Hereford sire or Angus dam. The ASA will assign EPD's based on breed average Hereford and Angus EPD's and the accuracies will be very low. If you know the specific Hereford sire, you can provide that info and get better EPD's and accuracy. Over much time and generations of being in the program with lots of data on calves reported for a long time, the accuracies will go up and better reflect the genetic potential of the cows.
