We are raising a holstein bull calf for beef, he's 4 months old. he lives with the goats and think's he is one of them. I'm not sure if I saw this or not, but I'm pretty sure he tried to mount to doe goat a few days ago. He has not been castrated. My wife has come up with the idea of getting a heiffer to raise with him and therefore saving us the expense of buying another calf to replace him when we butcher him, since in theory, he would have impregnated the heiffer. (I haven't really applied any thought to this at all) My first thought was that to cross a holstein with anything else, it would have to be another big framed cow like another holstein or else the calf would be too big to deliver. It seems to me that a holstein heiffer calf would be quite an investment, probably at least twice the cost of a bull calf. Is there anything else of comparable size that could be crossed with a holstein? Would it make more sense to just look for a bred heiffer and just continue to raise our bull calf as planned?
