The chests of 11 adult male goats were examined at 3 th - 6 th intercostal space on both sides of the thorax using 2.6-6 MHz convex transducer. All chambers of the heart were clearly visualized in the parasternal long axis view from both sides. The both ventricles and ventricular outflow with appearance of the aortic root is best to visualize from the right side at 4 th RICS (right inter costal space) and the transducer rotate bet 0°to30°caudally. Left ventricle with papillary muscle, chordea tendenea, mitral valve, aortic valve and pulmonary artery views were visualized at 4 th RICS (right inter costals space) 2 cm above elbow and the transducer rotate at different angles bet 0°to90° perpendicularly on inter costals space. During systole and diastole, dimensions of the left ventricle were greater than those of right ventricle, whereas size of the ventricles was significantly greater during diastole than systole (p>0.01). The dimensions of the interventricular septum, left and right ventricular free wall were greater in systole than diastole. Key words : Echocardiography- Egyptian Zarabi goats Introduction The domestic goat (Capra hircus) is a subspecies of goat domesticated from the wild goat. The goat is a member of the family Bovidae and is closely related to the sheep as both are in the goat- antelope subfamily Caprinae. There are over 300 distinct breeds of goat. Goats are one of the oldest domesticated species, and have been used for their milk, meat, hair, and skins over much of the world. ( Coffey et al, 2008 )
