What is the diet for a rocky mountain horse?

The diet of a Rocky Mountain horse will not be any different than a horse of another breed. This is because they may be different breeds, but they are the same species and eat the same things.

Hard feeds (Grains and manufactured feeds) are added in by humans when the horses caloric and nutritional needs cannot be met by hay or grass alone. this typically occurs when the horse is in work, pregnant, growing, or a hard keeper.
