New to site and new to cattle. I currently have 20 acres of very nice prarie grass. About 12 of it I put up in hay, keep some for the horses and sell the rest. The 12 that I hay I would like to put some cattle on and still be able to get about 350 squares per year off of it. My question is how many cattle can I safely put on and still be able to get that much hay per year? I know it probably depends on exactly how good the grass is but would 4 be out of the question? Looking at bred cows and then sell the calves.
