[QUOTE="Frankie, post: 740535, member: 13"] You're dealing with Red Angus, so I'm not going to try to talk about specific bulls. But, in general, EPDs are built by using data from individuals, their offspring, their sisters, brothers, aunts, uncles, and their offspring. Management plays a big role in actual weights. For example, if you breed a bull to a Charalois cow and a Jersey cow, would you expect the calves to have similar BW, WW and YWs? Or if you creep feed, you'd likely get heavier weaning weights. BUT if you take the actual weights of the several hundred calves these bulls have sired across the country, plus the weights of calves his brothers, sisters, uncles, etc., have produced, you'll get a pretty good indicator. That's what EPDs do. (More data is better than less, of course) EPDs are much more reliable than using actual data. As Dun says, accruacies are important. In a young bull, accuracies may change over time. I've seen flush brothers, same EPDs when born, but with very different EPDs as older bulls. [/QUOTE]
