Ultrasonography of the heart using Brightness mode (B-mode) and Motion mode (M-mode) was conducted using six apparently healthy crossbred female buffaloes to determine characteristic features and patterns in the normal heart. Ultrasonograms of the heart were obtained from the 3rd and 4th intercostal spaces in both the left and right sides of the thorax. There was no difference on the location of the heart observed among the six buffaloes. Ultrasonographic examination revealed distinct structures of the heart, including right ventricle, left ventricle, right atrium, left atrium, interventricular septum, interatrial septum, mitral valve, tricuspid valve, aorta, and left ventricular ou tflow tract. M-mode echocardiography revealed different patterns of the motions of the different structures of the heart. Gross examination of the heart revealed no abnormal lesions in all chambers and vessels. The heart appeared more visible on the left than on the right side resulting in more structures seen in the left side of the thorax than on the right. The measurements of the different cardiac structures obtained through gross examination were higher than those obtained through ultrasonography (P<0.01). This can be attributed to the constant motion of the heart during ultrasound examination. The results of the present study show that ultrasonography can be used to image the different structures of the heart in buffaloes. The B-mode and M-mode ultrasonograms obtained in the present study can be used as a reference for diagnosis of cardiac diseases and disorders in buffaloes.
