Purina® Equine Senior® Active Horse Feed, 50 lb



Purina® Equine Senior® horse feed, the trusted original senior horse feed, has been helping senior horses live healthy, long lives sinceits national launch in 1993. Todays horses are staying active longer than ever, and new findings suggest that healthy aging horses may benefit from a higher-calorie diet designed with controlled starch and sugar and balanced nutrients. Purina’s Ph.D. Equine Nutritionists and Veterinarians never stop researching new ways to address the specific needs of aging horses. Amplify® high-fat nugget and ActivAge™ prebiotic are just two of the senior horse nutrition breakthroughs included in Equine Senior® Active horse feed.
