Prevalence of omasal and abomasal disorders in cattle and buffaloes: A retrospective study

The present study was undertaken to ascertain the prevalence of omasal and abomasal disorders in cattle and buffaloes. This was a retrospective study of 2028 bovines. The overall prevalence of omasal and abomasal disorders was 6.71%, being similar for cattle (6.63%) and buffaloes (6.78%). The omasal and abomasal disorders comprised of omasal impaction, abomasal ulceration, abomasal impaction, abomasal bloat and late pregnancy indigestion, with an overall prevalence of 1.92%, 3.65%, 0.35%, 0.05% and 0.74%, respectively. Significantly higher incidence of omasal impaction in buffaloes (2.59%) compared to cattle (1.27%), and abomasal ulceration in cattle (4.68%) compared to buffaloes (2.59%), is new and interesting finding which could not be explained. The prevalence of other disorders did not differ significantly between cattle and buffaloes. The overall case prevalence was highest during post-monsoon (8.58%) and summer seasons (8.23%). The prevalence of omasal impaction was highest during summer season than other seasons except for winter season. The prevalence of abomasal ulceration in pre-summer was significantly lower than monsoon and post-monsoon seasons. The data so generated would be a basis for further research to establish the causes for species predisposition to omasal impaction and abomasal ulceration, and association of these disorders with seasons.
