If you leased a bull, what would/should it cost? I know about the trich test (before and after) and necessary vaccinations, etc. Had a neighbor ask about leasing one of my bulls. He has a small fall calving herd. I'm not-at this time-worried about loss of the bull but know it's part of the risk. 60 day breeding period starting December 1. If I agree to this, do I charge the value of one calf?
