[QUOTE="robert, post: 639070, member: 9171"] EPD stands for Expected Progeny Difference, obtained when you randomly mate cows to different sires, the numbers on a yearling bull whether they were in a large group of contemporaries or small provide only a prediction of what he potentially may sire based on pedigree and individual performance. Until there are progeny to compare in multiple herds against other sires then your bulls epds will not dramatically increase in accuracy. My main contention with epds in seedstock operations is that they are more of a modern day pi$$!ng contest that is supposedly more 'scientific' than a highly accurate selection tool because in many cases the numbers never get proven in a real world sense. (yearling or young cows flushed to the 'latest, greatest' with the 'best' numbers to create another generation of 'latest, greatest' that amount to little more than paper tigers). [/QUOTE]
