My horse has had chronic diarrhea pretty much his whole life. It goes away almost entirely when he is in consistent work, on grass pretty much 24/7, and in warmer months. He gets 1/2 lb pro elite diet balancer and 1/2 lb alfalfa, along with 3 flakes of hay morning and night. In the summer he doesn’t get the hay or alfalfa, just the 1/2 lb of balancer each feeding. He can not tolerate any grain other than that (will colic) He hasn’t been in work much lately due to the temperatures and ice... i don’t have an indoor. He has terrible diarrhea (like running down his legs) and I’ve tried almost everything as far as supplements. Gastrotech, daily gold, succeed, probios, etc. I’ve heard bio sponge by platinum performance is the way to go, but I am also looking into platinum performance’s platinum balance. He DOES NOT have stomach ulcers, but I have pretty good reason to believe it may be hind gut ulcers which are of course a pain to treat and diagnose. Any thoughts/suggestions? Thank you!
