Left and right horn length in both sexes ranged from 3.6 to 13.2 cm. Female goats had higher ear length than male goats. Tail length of Black Bengal goats ranged from 8.0±0.52 to 11.1±0.43 cm and tail breadth ranged from 2.1±0.10 to 3.6±0.43 cm for different age and sex group. Average male foreleg length in >24 months of age possessed higher than that of female. Average udder length and breadth of BBGs were 7.5±0.24, 11.7±0.44 and 14.3±0.46 and 5.9±0.16, 7.4±0.28 and 7.8±0.23 cm, respectively for age groups 6-12, 12-24 and >24 months of age. The average testis length and breadth in adult males were 9.1±0.18, 7.5±0.48 and 9.8±0.49 and 6.8±0.13, 5.2±0.27 and 6.3±0.32, cm respectively for 6-12, 12-24 and >24 months of ages groups.
