Feed instructions: Caution: you only need to feed a very tiny amount of this product. A tiny (1ml) scoop has been provided with your bag. One level scoop holds 0.6 grams of product which provides 1.2 milligrams of selenium. The Nutritional Requirements Council advises that a sedentary 500kg horse requires 1 to 1.25mg of selenium per day, and a performance horse needs 2-3mg per day. 1 scoop= 1 daily dose for a 500kg horse at maintenance assuming half of the daily selenium requirements have been met from the pasture. Increase to two scoops for a horse in heavy work.
We recommend working with a nutritionist or a vet to determine your horse’s daily selenium requirements.
