Oops, forgot to add one thing---most of the grains and grass hays are
low in Vitamin E, so if your horse isn't being fed alfalfa, then you
might want to supplement JUST A LITTLE. Adult horses only need 2-3 IU
of Vitamin E per kg of body weight, growing horses a little more. There
are some suggestions that higher levels may be beneficial to performance
horses, and that's fine, but don't go overboard too far on this one, as
it could interfere with the absorption of other fat-soluble vitamins.
Maximum levels should be under 20 IU/kg of body weight.
