 | Equine Ulcers and GI Health | Most Performance Horses Thought to Have Ulcers | Cindy Hale for HorseChannel.com | Research published in 2005 revealed the presence of ulcers in the colons of performance horses. According to the study, conducted by Frank Pellegrini, DVM, 63 percent of horses involved in competition sports, ranging from dressage to racing, suffered from colonic ulceration. Read |
| Equine Ulcers and GI Health | Performance Horse: Attitude Problem or Ulcer? | Madalyn Ward, DVM for horse911.com | Horses can’t use words to communicate with us so they have to send us signals when things aren’t right. How many times do we confuse their attempts to communicate with a bad attitude? When a horse is punished for trying to communicate it causes him even more stress and discomfort, and the downward spiral continues. How many good horses have had their careers cut short because of discomfort from ulcers? Find out the warning signs and symptoms for equine gastric ulcers. Read |

| Endotoxemia and the Equine Mesentery | Mesenteric Arterionecrosis in Natural and Experimental Equine Endotoxaemia | M. Oikawa; N. Masawa and H. Yoshikawa | To test the hypothesis that mesenteric arterionecrosis (MA) occurs in horses with naturally occurring endotoxaemia (ET) and in those with experimentally induced ET, the mesentery and gastrointestinal tract of 21 Thoroughbred racehorses (15 with spontaneous colic suspected to be due to ET, and six with experimentally induced ET) were examined.

| Colic in Horses | Prevalence, Demographics, and Risk Factors of Colic | Nathaniel A. White II, DVM, MS | Colic is one of the most difficult diseases to study with epidemiologic methods due to the large number of diseases, which create the signs of colic. Making a specific diagnosis is not always possible in horses with colic; therefore classification of the simple colic is a challenge. Information about incidence, mortality, and risk factors is helpful to the clinician in making decisions about individual cases as well as herd problems. An overview of the prevalence, demographics and risk factors of colic. Download PDF |
