Autopsy Found To Be Low in Selenium


“I had a horse expire last week at Washington State University, WSU. The doctor said she was deficient in selenium and thought it wise to give my other horse supplements, since they were on the same feed schedule. My horse did not die from low selenium but this was something picked up during autopsy. Do you have a recommendation?”

Answer by Ph.D. Equine Nutritionist, Kelsey Johnson Nonella:

The Northwest is notoriously selenium deficient. Horses that are selenium deficient have suppressed immune system and therefore are more susceptible to diseases they encounter, and can’t have optimal muscle function.

I would recommend starting your horses on Horse Guard right away. It will ensure that they are receiving 3 mg of organic selenium a day along with other vitamins and minerals that are typically lacking in a horse’s diet.

If you have any older and performance horses they could benefit from Trifecta. Trifecta contains a full dose of Horse Guard to ensure all their vitamin/mineral needs are being met, a gut supplement, hoof and hair supplement, and a powerful joint supplement (5000 mg glucosamine, 5000 mg MSM, and 100 mg hyaluronic acid) in one dose. All fifteen of our horses are fed Trifecta.

I hope this helps, and good luck with your horses.
