dc.description.abstractThe life expectancy of macaw ranges from 35- 50 years. Pet birds are many times deprived of conveniences as compared to their free-living counterparts. Captivity leads to boredom due to restricted area, lack of exercise and psychological changes in spite of good maintenance and precipitates into diseases in the long run of which one such condition is the risk of cardiovascular disease. A female severe macaw (chestnut fronted macaw) aged 7.5 years was presented for necropsy with a history of severe loss of feathers, wasting, chronic illness and death with a suspicion of avian tuberculosis. External examination revealed aberrations on the skin, erosions on the beak and injury on the right wing suggestive of self-mutilated wound. Grossly, carcass appeared dehydrated, blanched mucous membrane, thin watery blood, faecal material aroundthe cloaca and matting of feathers. The right leg was twisted and slightly deformed. Liver was swollen, dark brown in colour with enhanced lobular pattern and diffuse pale areas. Heart had a roughly elongated patchy pale area (approx. 0.5mm by 0.85mm) in the left ventricular myocardium, solitary nodule in the distal femur with cheesy exudate, meningeal congestion and strikingly all the bones were highly brittle and porous with grey white bone marrow. The cheesy exudate was negativefor acid fast organisms by Ziehl–Neelsen staining. Histopathologically the chief lesion was multifocal necrosis of cardiac myocytes and perivascular degeneration of fat in the cardiac vessels suggestive of cardio myopathy. In addition, multifocal coagulative necrosis of the liver and diffuse congestion of the lungs was noticed. This documentation highlights the need for more studies on avian cardiology as clinical signs on cardiac compromise seems to be subtle and owners fail to recognise these changes.en_US
