Land O’Lakes Purina Feed, St. Louis, MO, has developed its new Equine Senior Active Healthy Edge horse feed, which joins the original Equine Senior horse feed formula as a nutritional choice for feeding aging horses. Because not all senior horses require a complete feed with roughage built in, Purina has introduced a more calorically dense formulation specifically designed for the active, aging horse that still has the ability to chew and digest forage effectively. The new product is a pelleted feed with a high fat and fiber, controlled starch and sugar formula that delivers all the vitamins and minerals the aging horse needs.
