I had a group of cows I purchased where one had been Ai'd to him. He (the calf) was always head and shoulders above the rest, wide feet, heavy muscled, lots of eye appeal, my only complaint would be he occasionally has a little too much attitude, occasionally. I liked the calf enough, I left him intact and use him as an extra bull or something to use in a small pasture. This was just one calf I've seen so someone else might have a completely different opinion.
I have a cow by him and am pretty happy with her. She has a Black Granite son that I love and he is built right. I'm getting ready to flush her here in a couple of weeks as she is a great looking cow with everything I could ask for genetically.
