Update
I was beginning to think I had paid more for that bull than he was worth.
Anyway I had the Vet come and take a look at him.
He said,, the bull was very healthy, but possibly just a little young, so he gave me some pills to feed him once per day.
The bull started to service the cows within two days . all my cows!
He even broke through the fence and bred with all of my neighbours cows!
Hes like a machine!
I dont know what was in the pills the Vet gave him but they kind of taste like peppermint.
