STUDY ON THE PREVALENCE OF GASTRIC ULCER DIAGNOSIS IN THE CASPIAN MINIATURE HORSE BY ENDOSCOPY

The aim of the present study was to determination the prevalence of gastric ulcer in Caspian miniature horse. The design Field- laboratorial study on 23 Caspian miniature horses. Feed withdraw 12-16 hours before study and the owners or riders completed a form about housing, medication, age, sex, cell boold counts and the biochemical profile tests were carried out. Endoscope performed through the nostrils into the stomach for a systematic examination. Findings of endoscopy were analyzed by chi-squire test. Moreover, mean valus of the laboratorial values between horses with or without gastric ulcer were compared by T- test. Gastric ulcer was evident in 47. 82% of cases. However, 81. 9% and 18.1% of ulcers were in nonglandular and glandular regions of the stomach respectively. There was significant differences between glandular and nonglandular ulcers (p<0.01) and between genders (The females had higher incidence of gastric ulcer than males)(p<0. 05). Low incidence of gastric lesions were seen in horses which received antihelmentic drugs. Moreover, horses with history of long-term treatment with NSAID, had significantly higher incidence of gastric ulcer in the glandular region (p<0.05). The occurrence of gastric ulcer was associated with over exercise (p<0.05). There was no significant differences between serum Ca, Na, K, P, Mg and total protein levels in horses with or without ulcer. However horses suffered from gastric ulcer, showed a high serum levels of fibrinogen(p<0.05).
