[QUOTE="cotton1, post: 1305116, member: 14689"] Ebeneezer-What of my cattle that have BOTH high milk AND high maternal EPDs? I have several of those. My cattle milk well, AND breed back well. I understand the idea of maternal, or milk,but there can be both. There should be both. A good cow should raise her calf, and get pregnant while she does it right? Do they need extra foodstuff? I'm sure they do. The only way I see to make them better is to retain the milk ability, and fertility and reduce input needed by reducing overall size of the mature cow. High growth EPDs stacked are going to make larger cattle. Median growth EPDs are probably going to make cattle the same as the parents or vary a little either way but not very much in my opinion. Just saying that the larger the cow, the more input she requires most likely, but not always. The more she milks the more input required, but not always. The ones that will do it all are few and far I admit. Overall, I just believe a 1200lb cow can be productive in all facets with less input than a 1800lb cow. The irony to me is, that I want to reduce the size of my cattle over time because I want to run more cows per acre. The cows that I have found with both high milk and high maternal EPDs have been needle in a haystack to find. They all tend to be 1700-2000lb cows in my experiences.That does not give me much faith in the EPD system. I know what Ebeneezer is saying is right, not arguing, just thinking out loud I guess.
