The most important thing in a horse’s diet is water. Provide plenty of fresh clean water at all times. All forage grazing animals need long stem forage in their diets. The long stem forages can be supplemented with hay forages made into cubes and pellets. We recommend that you feed by weight and not by volume. 1-2% of a horse’s weight should be fed daily in hay forages. This amount may vary depending on the animal’s needs and the horse’s activity. Therefore, if a horse weighs 1,000lbs and is a performance horse, 20lbs of forage would be sufficient, however, consult with a veterinarian or nutritionist for selected forage types and specific needs for your animal(s). Make feed changes gradually over a period of 7 days.
