abstract
Comparative macro morphological study on the Appendicular Skeleton of Arm Region of Domestic pig (Sus Scrofa indicus) and Pygmy hog (Porcula salvania) was conducted. The study was carried out in Department of Anatomy and Histology, College of Veterinary Science, Assam Agricultural University, Khanapara, Guwahati, Assam, India in August month, 2015. The results showed that appendicular skeleton of arm region of dome pig (Sus scrofa domesticus) and Pygmy hog (Porcula salvania) was formed by humerus, a long bone. The humerus of Pygmy hog could be easily distinguishable from that of dome pig by some unique gross features viz., the radial and olecranon fossae of Pygmy hog communicated with each other by way of supratrochlear foramen, and presence of well-developed deltoid tuberosity.
