Like has been said, it will depend on many things. Not only the horse or what else the horse is eating (pasture and feed). Another thing to consider is the quality of the hay. The better quality should last longer. A lower quality will have more waste. It will also depend on how you feed the hay. Are you feeding the hay in a feeder or just on the ground. You will hav more waste without a feeder, which means you'll go thru more hay.
General rule is a horse will eat 1 to 2% of their body weight. A horse that weighs 1000 lbs would eat 20 lbs of hay. Hay bales will vary in weight. Figuring one weighs 50 lbs, it would be safe to say a horse would eat 1/2 bale a day or 15/month. It is better to estimate high instead of the minimum and running short. Posted via Mobile Device
