Beginning November 3rd, Purina Equine Senior and Senior Active is releasing a newly formulated and improved feed. As horses age, it’s important to adjust their diet accordingly to meet all their nutritional needs. New technology and research has allowed us to do this more efficiently. Equine Senior and Senior Active is still the same feed you love and trust, but now with an added prebiotic called ActivAge. ActivAge is a proprietary of Purina and will aid in battling against increasing inflammation and a declining immune system. Research has found that horses eating Equine Senior with the ActivAge prebiotic maintained or decreased inflammatory cytokine levels and had a stronger response to the flu vaccination. Equine Senior & Senior Active is still the #1 Veterinary Recommended feed. Find it today at Bar None Country Store!
