Abstract

A carcass of 9 months old male Surti buffalo calf was presented to the Department of Veterinary Pathology, Kamdhenu University, Navsari, Gujarat with the history of swelling over eye region and partial off feeding in the last 5 days. A necropsy was performed to clarify the cause of death. External examination revealed rigor mortis in whole body, protruded tongue, swelling at eye ball, severe congestion of eye mucous membranes, shrunken eye ball, erythema on right inner thigh hind limb, prepuce and thoracic sternal area. Internal examination revealed liver was slightly enlarged and friable with bulging off the cut surface. There was presence of granular thick bile in gall bladder. Lungs showed cranioventral consolidation and focal emphysema with oozing out of blood on cut surface. Examination of heart revealed petechial haemorrhages on epicardium with grey, white shiny and 1–2-inch sized uneven shaped patches on right and left ventricle. Myocardium also revealed focal grey white patches. In left ventricle, at 4 places large grey white patches noted. Endocardium of right ventricle was thin with slightly white and left ventricle was comparatively thick with white patch. Upon cutting of left ventricle, gritty sound was heard. Histopathology of heart revealed fibrosis in myocardium as well as endocardium with infiltration of leukocytes. Animal was dead. On the basis of these findings, it may be concluded that the animal might have been died due to restrictive cardiomyopathy as a result of f ibrosis in endocardium and myocardium.
