It all depends on the quality of the grazing. Normally you allow one acre of land per horse but on poor quality grazing I would say one horse per two acres. Poor grazing is better than good grazing for ponies, donkeys and mules. You might be able to get 75 or 80 horses on 72 acres but if the grazing were poor, a more realistic figure would be 40.
