Pathology of cardiac disorders In cattle

Abstract

The present study was undertaken to assess the prevalence and pathology of various cardiac disorders in cattle. The data collected from the autopsy records maintained at the Centre of Excellence in Pathology, Mannuthy and hundred and one samples of heart obtained from both the slaughtered cattle and necropsy cases formed the basis of the study. Fifty five per cent hearts showed lesions of varying type. The highest incidence was for sarcocystosis (45 per cent). Vascular lesion~were present in 33.8 per cent cases. Other myocardial lesions encountered were myocardial degeneration, myocarditis and other cardiomyopathies of unknown etiology. Endocardial fibroelastosis and valvular sclerosis were observed in four cases. Valvular and coronary vessel lesions showed correlation with hypertrophic cardiomyopathy. The incidence of pathological disorders encountered were relatively high. The need and scope for investigation into the pathological disorders of bovine heart were highlightened.
