Some senior horses are easy keepers who maintain body condition on hay or pasture alone, or are not able to eat the minimum recommended amount of another feed without gaining unwanted weight. These horses need a concentrated source of amino acids, vitamins, and minerals. They can also benefit from Outlast(R) gastric support and ActivAge(R) prebiotic technology. Enrich Plus(R)Senior is a concentrated, pelleted ration balancing horse feed that may be fed as a horse's sole ration along with quality hay or pasture to provide the proper balance of nutrients without unnecessary calories. Also a good choice for performance horses have lower calorie needs or get most of their calories from quality hay or pasture. | Purina Enrich Plus Senior Ration Balancing Horse Feed | Size 50 lbs
