Abstract

An abnormal female Korean native calf at five months age with five legs was observed macroscopically and radiographically. External features included two normal forelimbs, and hindlimbs, and an abnormal forelimb which was underdeveloped. A rudimentary forelimb, which was attached to the pectoral region, was observed at the right axillary part. The extra forelimb was scapural and humeral meromelia. It consisted of an underdeveloped forearm (antebrachium), several carpal bones (three bones), large metacarpal bone (Mc. 3 + 4), and two digits with two hoofs. The proximal, middle and distal phalanges, proximal and distal sesamoid bones are normal.
