Abstract

Although abomasal ulcers in cattle have been recognized in the past, an epidemiological study on buffaloes and data on frequency and topographic location of ulcers in abomasum is still lacking. This case control study evaluated the prevalence of type 1 abomasal ulcers in slaughtered buffaloes of India. The sample size was calculated by a standard epidemiological method. The location, number and type of ulcers were recorded photographically and on a predesigned sketch diagram, representing all anatomical parts of the abomasum and both surfaces. On the basis of their macroscopic and microscopic appearance, the type 1 ulcers were classified into four subtypes, viz. type 1a, 1b, 1c and 1d. Out of 134 examined abomasa, 66.42% had type 1 ulcers. The prevalence was significantly higher during the summer than in winter. Buffaloes studied during the summer had 3.39 times greater odds of having a higher prevalence of type 1 ulcers than buffaloes studied during the winter. Although the prevalence did not differ significantly between different age groups, older animals had greater odds of having abomasal ulcers. Type 1b and 1c were the most frequently observed ulcers. Although the abomasal body had 12.32 times and 6.12 times greater odds of having abomasal ulcer than fundus and pylorus, respectively, the ulcer location did not change with increasing age. All ulcers, except type 1a were more concentrated in the caudal third of the parietal surface of the abomasal body, along the greater curvature, and were usually multiple. We believe that abomasal ulcers may be an important cause of the decreased production of buffaloes in this region due to the high prevalence and multiple etiology.
