Just thought people might like to know about the new Hoffman's Ration feed product. It is NOT a mineral/supplement, but a feed. My friend has a horse that she has had much difficulty with keeping weight on. She started him on the Hoffman's Ration and he gained weight! :)
More info at: Hoffmans Horse Minerals - Horse Ration there are additional links at the bottom of their page.
I use the Hoffman's mineral and would definitely try this feed if I had a hardkeeper.
