If a horse is receiving 4 lbs of grain at .60 ppm of selenium this would be 1.36 grams of selenium. The say some adds a multi vita/min containing 20 mg of selenium per pound which is 1.25 mg for one ounce and 2.5 mg for the recommended 2 ounce dose. This would mean a total of 3.86 mg of selenium from concentrate and supplement alone. I have read that 1-3 mg for an average 1000lb horse at maintenance. Is this correct?
