One of the most important aspects of caring for your horse is proper feed and nutrition. If you are buying the horse from another owner, you may already know its diet. If not, you need to take a crash course in nutrition.
Many feed stores can give you advice and there are independent feed specialists available. In addition, most major manufacturers have advisors who will work with you to design a good program for your horse.
