[QUOTE="alexfarms, post: 771526, member: 8677"] I once sold a bull to a man who was very attentive to epd's . The bull I sold him had a negative bw epd and a bw ratio of over 100. Not surprisingly, he was dissappointed in the bull. He said the bull never threw any really big or really small calves, but his bull calves were in the upper 80's and just a little too thick for him. He went on to explain that he believed the bull would have been alright if he just would have thrown some small calves to bring the average down like most of his low bw sires did. I responded 'so you're criticizing the bull for being consistent?'. He sold the bull, but not before enough data had been sent into the TPR system to get him listed as a bw trait leader. I beleive one of the drawbacks of epds is they don't express a bull's consistency, only averages and that is kind of what your bell curves expresses also. Some pretty smart people have told me I am wrong and epds do express consistency. They may be right, but I don't see it. I think epds are displayed with the assumption of consistency, which often isn't there. [/QUOTE]
