The present study was carried out on the humerus of six Blue bulls. The shaft of the humerus was slightly twisted, cylindrical and presented four surfaces. The lateral surface presented a nutrient foramen in its distal third. It bore a small teres tubercle placed at the proximal third. The musculo-spiral groove was shallow. The deltoid tuberosity was found as small rough convexity and less prominent. In the proximal extremity, head was roughly rounded and faced caudo-dorsally. The neck was well-defined and was distinct only caudally and laterally. The lateral tuberosity was large and curved over the inter-tubercular groove. It consisted of a prominent cranial part and a less well defined small caudal part, which was triangular in outline. The minor tubercle was much smaller and did not divide noticeably. The inter-tubercular groove was present between both the tubercles. The distal extremity had two condyles, two epicondyles and two fossae. The coronoid fossae and olecranon fossae communicated by a small supra-trochlear foramen in some specimens.
