[QUOTE="Frankie, post: 462015, member: 13"] I think you misunderstand. EPDs strip out management, climate, etc. Since they're created with information on animals from all across the country, in different climates, different management, they are the best indicator of an animal's breeding ability. If you use just the actual performance of an animal, his own BW, WW, YW, etc., those could be manipulated by management. A young animal's EPDs are possibly going to change as he gets older and information is reported on his calves, his siblings, etc. But the key to avoiding that is to AI to only established bulls with high accuracies on their EPDs. Or buy a bull whose parents are from a long line of cattle with the EPDs you're interested in. [/QUOTE]
