There are almost as many answers to those questions as there are bulls out there! It depends on what caliber bull ur talking about, where the bull comes from & who's involved in selling him. Most people who are shopping for bulls are looking for a bull to breed cows, and I'd say the majority pay $2-5,000 for full interest/full possession. If you're talking about an interest in a stud quality bull, that's a bigger range and a bigger price tag. A lot of variation among different breeds, but most of those bulls in the breed I'm famiar with sell for $10-50,000 and may have a few partners or several. I think most of those deals get put together between folks who know each other or have done business prior to, meaning not many folks are looking for a partner they don't know. As far as what can be made off of em, I doubt some of em ever make much if anything. The few that hit probably pay pretty good, but you have to sell a bunch of semen at $25/straw before you ever start making money on a bull like that.
