A horse needs hay for roughage. There are many hay substitutes on the market, they should always be feed in addition to hay. Hay should never be dusty or damp. Approximately six flakes (There are between nine to 12 flakes in a bale of hay) a day is average per horse. A horse has a very small stomach in relation to its body, three meals a day is preferable to two. Salt is extremely important to the diet of the horse and can be purchased in blocks. The red iodized salt is better than the plain. Feeding hay alone is never enough for the working horse, he must also have grain. The more work done, the more grain he needs and vice versa for less work. The amount of necessary grain varies for each horse according to his size, weight, and amount of exercise he receives. In cold weather, cracked corn is excellent to help keep the horse warmer. Never over grain (or over work the horse without proper cooling) as this can cause the horse to founder. Always make sure the grain is in good condition before feeding (not moldy, etc.). Vitamin and mineral supplements are a good additive to the horse's diet. Fresh water should be kept in front of him at all times except when he is too hot from a work out. Then only small sips should be allowed.
