[QUOTE="SRBeef, post: 975545, member: 7509"] I believe this discussion is coming together. In my small cow/calf and freezer beef operation I have found that the ratio of 205 day adj calf weaning weight to cow weight at weaning is the key measurement of cow performance, at least in my situation. The ratio of calf weight to cow weight at weaning seems like it would take into account both the milking ability and the growth ability. I want a herd of cows that every year wean a 205 day calf more than 50% of their own weight at weaning and does it on all grass with no creep. Creep masks many different things. Of course she has to be able to calve unassisted to get there also. Here is a picture of my favorite cow taken the day after weaning, Oct 24th this year. This cow calves easily every year, rebreeds quickly, and has always weaned a calf in the 55% of her weight at weaning. And she stays in good condition and around 1250 lb doing it. I have no idea what her epds are as she is a commercial I purchased locally for $600. a few years ago. I do use good calving ease and good milk epd bulls from Jerry Huth. [img]http://i1108.photobucket.com/albums/h414/SRBeef1/IMG_1427r_Molly10-26-12.jpg[/img] So it is possible to have good milk without giving up condition, calving ease or growth. I think if we selected cows and bulls for 205 day weaning weight as a percent of cow weight at weaning, with perhaps a 50% target, we might cover a couple bases at one time and not end up with a herd of dairy cows. jmh beginners opinion. Jim Here she is with this years calf three weeks before weaning [img]http://i1108.photobucket.com/albums/h414/SRBeef1/IMG_1134_abeautifulsightthistimeofyear100112-1.jpg[/img] [/QUOTE]
