In this study, fifteen hip bones from known sex of Black Bengal goat were collected to investigate the osteological features to determine sex. The important osteological features of collected hip bone were studies and they were classified into two groups (male and female) on the basic of osteological features. Conjugated diameter of pelvic inlet was more in female (12.09±0.12 cm) compare to male (11.47±0.26 cm) group. Transverse diameter of pelvic inlet was also more in female (9.29±0.19 cm) than male (8.21±0.08 cm) group. Pelvic outlet and ischiatic arch were larger and wider respectively in female than male group. Wideness of ischiatic arch was larger in female (2.94±0.02 cm) compare to male (2.41±0.08 cm). Obturator foramina were smaller in male group. Anteroposterior diameter and mediolateral diameter of obturator foramina were more (3.60±0.08 and 2.01±0.09 cm) in female than male (3.21±0.08 and 1.81±0.08 cm); respectively. Those findings indicate that, the differences of important osteological features between two groups help to determine sex (male and female) in Black Bengal goat. 1519570482.php
