Abstract: A necropsy case of Vrindavani cattle was presented at the ICAR-Indian Veterinary Research Institute, Izzatnagar, Bareilly (Uttar Pradesh). The postmortem examination of a six-year-old female Vrindavani cattle revealed slipped and dislocated femur bone, resulting in immobility for four days prior to death despite treatment efforts. External examination showed good carcass condition, pale mucous membranes, hind limb rigor mortis, hemorrhages, pus formation, and black discoloration in affected muscles. Gross examination displayed frothy exudates, tracheal and pulmonary hemorrhages, emphysema in cranial lung lobes, consolidation in caudal lobes, and fibrinous pleural appearance. Petechial hemorrhages were present on the epicardium and endocardial wall, along with clotted blood in the heart's ventricles. Liver exhibited rounded borders, black patchy discoloration, and mottled necrotic areas on cut sections. Spleen and kidneys displayed petechial hemorrhages, cortico-medullary junction congestion, and severe serosal congestion and mucosal congestion in the intestines. Microscopic examination revealed mild subacute bronchointerstitial pneumonia in the lungs, vacuolar degeneration and mononuclear cell infiltration around the central vein in the liver, and severe interstitial infiltration of mononuclear cells in the kidneys. The findings suggest death by trauma-induced septicemia resulting from femur bone displacement and associated complications.
