Purina’s Equine Adult is a complete and easy way to feed horses in their middle years, that are active, not so active or easy keepers. These are often the most demanding years of a horses life and maintaining proper dietary balance can be complicated and confusing for owners. Recognizing this, Purina’s Research Center developed Equine Adult to provide a total nutritional package of high-quality protein, energy, vitamins and minerals along with highly digestible fiber.
