Can you tell me how much salt I would need to include in my horse's daily feed if I were to feed by hand? I normally feed salt free choice, but my one horse eats way too much salt block if left on his own. Also, is there any particular type of salt that I should feed (if I add to feed manually)? For example, is regular table salt the same thing that salt blocks are made of?

The National Research Council Nutrient Requirements of Horses publication states that "horses are tolerant of high levels of salt in their diets if they have access to fresh drinking water." In addition, 10 to 60 grams of salt should be added to the horse's ration daily depending on the size of horse, type of ration, and amount of exercise. Rations high in hay do not require as much salt as high-grain rations. Loose salt can be obtained at most feed stores. Salt blocks or mineral blocks are preferred, but both should not be used at the same time. Read more about feeding salt.
