Thank you for your question about your Appaloosa’s diet. This may vary quite a bit depending on what your horse does for a living!
We normally feed about -% of a horse’s bodyweight in forage or pasture equivalent. For a 1000 pound horse, that would be 15- pounds per head per day. If your horse is not doing much work, we might add a forage balance product at 1-2 pounds per head per day to provide additional amino acids, vitamins and minerals. Salt should be available free choice and fresh clean water should be available at all times. If your Appaloosa is being worked regularly, you would need to add a grain based feed to provide the extra Calories to maintain body condition and perhaps feed less of the balancer product.
Best of luck!
