How the Horse Hay Needs Calculator works
Most horses eat about 1.5 to 2.5 percent of their body weight in forage each day, so hay per day = weight × percent ÷ 100 × number of horses. Bales needed = total hay ÷ bale weight. Pasture grazing reduces the amount you need to feed, while hard work, cold weather, and lactation raise it. Buy extra for waste, because horses trample and drop some hay. Example: A 500 kg horse eating 2 percent of its weight needs 10 kg a day, which is 15 bales of 20 kg a month.
