Should I supplement my horse’s diet with selenium?
Selenium is an important antioxidant for the protection of cellular membranes. However, excess selenium in the horse’s diet can lead to substitution of sulfur in the keratin fibers with selenium, resulting in poor structural integrity. Chronic selenium toxicity can result in hair loss, coronitis and bleeding of the coronary band, as well as sloughing of the hoof and even laminitis.
