Having a debate with a friend of mine that thinks
you are neglecting your horse if you don't supplement with vitamins daily. I
have been told that if you feed high quality hay (mine is: Eastern Oregon
orchard grass) with beet pulp you should be fine. Mine are also on pasture in my
backyard and get Sel supplement since I'm in the NW. Is it true you must add
vitamins or just a waste of money?
