Looking at her grain alone, triple crown senior(6.5lbs/day) she is only getting 1,105 IU's, She gets 6-9lbs(can't remember if she gets 1 or 1.5 scoops a feeding) of alfalfa pellets a day also, I can't seem to find if there is vitamin E in alfalfa tho. She also gets grass hay, but from what the vet told my barn owner, that isn't going to have much vitamin E in it.
I read that they should get minimum of 2,000 IU's per day. So should I add some vitamin E to her diet? My barn owner also said not to get one with Selenium. Does anyone know the max Selenium they should have in their diet?
