[QUOTE="Frankie, post: 20389, member: 13"] I don't know that any breed association puts actual weights on EPDs. They shouldn't anyway. So why would you expect an actual marbling amount when you look at marbling EPDs? Bull #1 has a marbling EPD of .25 and bull #2 has a marbling EPD of .50. No one can tell you how their calves will marble because of management and the cow's influence. But we will EXPECT bull #2's calves to marble twice as much as bull A's calves. The .25 marbling you reference will only be useful if you're comparing another animal's marbling EPD. That's how EPDs work. As far as actual data is concerned, it is heavily influenced by management. Calves born in the spring are generally heavier than calves born in the fall. Creep fed calves with the same genetics will likely wean heavier than non-creep fed calves. Animals with the same genetics might wean heavier calves in areas of moderate tempertures than where it's excessively hot or cold. EPDs takes all that into consideration. You may not like them or use them and that's fine. But if you're expecting to sell breeding stock, you may find your customers are pretty well schooled in EPDs. [/QUOTE]
