Liquid747 is also low in the vitamin department. It has a lot of different Amino Acids, but not very much of them. To get the nutrition your horse needs on a grain-free diet, you'd have to feed 10-12 oz a day, which makes it expensive to feed and the horse might appreciate that much "stuff".
Dr Foster's doesn't have any supplements that would be suitable for a horse on a grain/feed-free diet.
