“I have been giving my gelding a loose salt product containing hi mag, it claims to be for the IR horse. I use Horse Guard. I don’t know how much magnesium is the correct percentage to give and if I need the loose salt with the hi mag or is Horse Guard enough? Don’t want to double dose. At your convenience I would love to hear your advice.”
Answer by Ph.D. Equine Nutritionist, Kelsey Johnson Nonella:
Thank you for the question. The addition of the loose salt with magnesium is perfectly safe, and good for your horse that is IR. Horse Guard contains 1.2 g of magnesium. Your horse requires 10 g per day. He is receiving most of his magnesium from the hay and concentrates you are feeding him. I don’t know how much your salt contains, but products designed for calming contain 5 g of magnesium and pair great with Horse Guard.
