  26. 26. Questions
  27. 27. Your Questions: <ul><li>Should you feed supplements to &quot;prevent&quot; ulcers? If so, what would you recommend? </li></ul><ul><li>Does one dose a day of Gastrogard act as a preventative for ulcers? </li></ul><ul><li>Someone has told me that Ulcergard can actually cause ulcers when the medicine is discontinued – is this true? </li></ul><ul><li>How do you help reduce causes of ulcers when you are in a boarding situation? </li></ul><ul><li>I heard music playing in a barn can cause ulcers in horses-is this true? </li></ul><ul><li>How do probiotics factor in prevention/symptom management of ulcers? </li></ul><ul><li>Bute and ulcers... should you give ulcer preventive along with meds? </li></ul><ul><li>Is grinding of my horse’s teeth a symptom of ulcer pain? </li></ul><ul><li>Can ulcers be caused by bacteria as in humans - H. pylori and is there a treatment for same? </li></ul>
  28. 28. Your Questions: <ul><li>I have read many articles that alfalfa hay is a great way to naturally buffer the acid in the stomach. How much do you recommend giving a day and how often? </li></ul><ul><li>Does sweet feed really cause ulcers? </li></ul><ul><li>Are there natural alternatives to treat ulcers? </li></ul><ul><li>My horse was fighting pneumonia and taking alot of meds. While adding Ulcergard in the morning, I also added Zantac at night to prevent colic or ulcers. The Ulcergard is very costly, but I was very nervous about his stomach and had to do something. Your thoughts? </li></ul><ul><li>What do wild roaming mustangs do to support their gastric health? </li></ul><ul><li>Does it make sense to go to the expense of scoping (particularly if you have to travel a long distance to get this done) for definitive diagnosis? </li></ul><ul><li>Can you discuss ranitidine and sucralfate, as well as compounded omeprazole? </li></ul>
