Don't forget that the number one risk factor for gastric ulcers in horses is a change in stabling. If you are traveling to a show, using an gastric protectant is recommended. GastroGard® and Ulcergard® contain Omeprazole, which is extremely effective for treating and preventing ulcers. Compounded versions of Omeprazole have been tested and many contained only 20% of the Omeprazole necessary so using brand-name Omeprazole is strongly recommended. he only downside of Omeprazole is that it takes 3 days to take full efficacy. Ranitidine is a faster-acting ulcer prevention but may be slightly less effective than Omeprazole. For most horses, using Ranitidine during travel should be enough to prevent ulcers caused by change in stabling.
