I fed Poulin E-Tek Ration Balancer to a number of horses with success for years, but got an OTTB with gastric ulcers last fall and despite lots of ulcer meds, wasn’t doing as well as I had hoped.
My vet recommended switching to Platinum Performance GI, and it has made a world of difference. Not the least expensive, but I now have a happy horse, gaining weight and progressing in his work. Saving money as I don’t have to give Gastroguard/ Ulcerguard. Added bonus, the feed comes with colic care eligibility.
