We recently spent $2,500 on a young Black Angus bull. We put him out with the herd, but he just ate grass and wouldn't even look at a cow. I was beginning to suspect he was gay, if that's possible with a bull. Anyhow, I had the Vet come have a look at him. He said the bull was very healthy but possibly a little young, so he gave me some pills to feed him each day. The bull started to service the cows within two days. All of my cows! He even broke through the fence and serviced all my neighbor's cows! I don't know what was in the pills the Vet gave him, but they kinda taste like peppermint.
