As you can see from my horse's profile pictures, he's a hard keeper. So far I've been adding corn oil to feed, mixed in senior feed with his regular Sweet Mix, and am currently feeding him 6 flakes of hay + 1 flake of alfalfa hay per day (we can't afford much more than that in hay plus this is more than what he will usually finish) So far I'm getting very minimal results. I don't have as much of a problem in the summer time with all the grass but winter has kicked his butt as of now. I'm buying Farnum Weight Builder in about a week so hopefully that will help.
Any other suggestions?
