Hello lovely HHO'ers!I'm looking for recommendations for a Mineral/salt lick for a (greedy guzzle-guts!) horse with ulcers. Are the Protexin Gut Lix ones any good? The Himalayan block in the stable doesn't get touched. I have bought the Horslyx ones before, and not only have they disappeared ridiculously fast, but I'm trying to go sugar-free... Any suggestions/reviews gratefully received!Thanks.
