I just have commercial cows, I do however AI a sprinkling of them each year. I took the class, and have the stuff. I might as well do a few of them any way. Anybody ever use any of the club calf bulls on bull barn on just commercial cows. I don't want a show calf, I just want to try about three of my cows on one of them. Or, are they a little to impractical for what I do?
