If you have ever owned a bull or stallion you know how much work/money/ and stress it is to own one. It is MUCH easier to go with AI (Artificial Insemination). Also with the natural way there are dangers. Twice since I have got my bull he has mounted a cow and the cow was in a weird position when mounted and hurt or broke its hip. One of the cows had to be sent for meant because a broken hip in cows cannot be fixed. The other cow just severely bruised the hip and is ok but had to stop being milked and I lost all money that could have been made from her milk.
OMG, that's aweful..So how much weight is a bull? I mean to do that much damage they have to weigh a good TON
