[QUOTE="UG, post: 1516987, member: 714"] I don't blame the breed associations for the trend in certain EPDs. EPDs are tools that the associations provide their members and commercial customers. It is interesting to see how so many breeders jump on a trait, and has been stated before, they feel that more is better. A very wise and older seedstock producer has often commented that as we put selection pressure on one trait, it will generally have a negative effect on another (i.e. more milk often results in decreased breed back of cows; higher growth often results in larger birth weights and more frame). A trend that seems to be picking up with some producers is selecting for smaller, "more efficient" cows. Around 2000 Kit Pharo was one of the only producers out there promoting that a smaller cow is more efficient. It seems in the past five to ten years more and more breeders and "experts" are promoting that as well. Though I agree that our cows were getting too big 20 years ago, it seems that for many environments we may be going to far the other way. Feeders want calves that will grow, and they are not bidding as much (or at all) for the smaller framed calves, as they recognize that they will finish too early and lack carcass weight. [/QUOTE]
