So I have ten embryos I have to implant this spring. Some I'm not worried about as far as calving ease and BW. Some I want to use on older cows. Two questions. First on an Embryo how do you consider the calving ease? By the bull or the female or the average of both? Also how old is too old. I have a few ten year old cows that have no problem milking, udder quality or calving. Are they to old or should I use some 3 or 4 year olds that have better genetics therefore I would rather AI them and not use them as recips. Thanks Mike.
