Abstract |
An abnormal Korean native cow of six years old with extra legs was observed macroscopically and radiographically. The results were summarized as follows; 1. External features included two normal forelimbs and hindlimbs, and two extra forelimbs which were underdeveloped. The extra forelimbs of different length attached laterally to the cranial regions of neck on right scapula. 2. The large extra forelimb had scapular meromelia. It consisted of underdeveloped humerus, antebrachial skeleton, several carpal bones, metacapal bone(MC3+4) and two digitis with each pairs of hoof and a rudimentary hoof of dewclaw. 3. The small extra forelimb had scapular and antebrachial meromelia. It consisted of underdeveloped metacarpal and carpal bone, severely deformed humerus, fused carpal bones, and two digitis with two hooves, and a rudimentary hoof of dewclaw. 4. The dermoid cyst was observed between the large and small extra forelimbs. |
