Prevalence of gastric and duodenal ulceration in 691 nonsurviving foals (1995–2006)

The prevalence of ulcers in nonsurviving foals is low. Foals with gastrointestinal disease are more likely to have ulcers than foals with other primary diagnoses, and older foals are more likely to have ulceration than neonates. The prevalence of ulceration did not appear to be related to hospital-wide antacid medication use in neonates.
