We believe our steer has an ulcer. We wormed him with safeguard today and will be giving him yogurt tonight. I was reading through all of the old posts about ulcers and read where a couple of people recommended GastroGuard. Has anyone else used it? I'm curious if the dosage and treatment length is the same for cattle as it is for horses. The cost made me take a deep breath, but we've invested so much in the project already I'm willing to try this if others have had really good results.
