The study was conducted to investigate the reproductive and productive performance of Black Bengal goat in different parity reared in semi-intensive system. Twenty-five pre-puberal (6-7 months) female Black Bengal goats were selected on the basis of their phenotypic characteristics and their ancestral history from goat Development farm, Savar, Dhaka. The animals were vaccinated against peste Des petits Ruminants dewormed and deeped in 0.5% malathion solution. They are allowed to graze once concentrate supplement was fed at the rate of 300, 200 and 100 g/d to does buck and kid, respectively. Different reproductive and productive characteristics of the Black Bengal goat were recorded during 2 years. Young female attained puberty at an average age and weight of 209 ± 32.25 days and 8.08 ± 1.28 kg, respectively. Mean age and weight at 1st kidding were 401.5 ± 32.08 days and 15.41 ± 1.35 kg, respectively. Growth rate at 1st gestation period was 49.56 ± 9.15 g/d. Sex ratio of male: female kids born was found to be 56:44, 48:52 and 51:49 in the 1st, 2nd and 3rd parity, respectively. It required 1.2-1.4 services per conception with average gestation length of 148 days. Average litter size in the 1st, 2nd and 3rd parity was 1.08, 1.76 and 1.96, respectively. Post partum heat period was 48, 43 and 38 days for 1st, 2nd and 3rd parity, respectively. Kidding interval also reduced significantly (p<0.05) from 199 days in 2nd parity to 187 in 3rd parity. Average birth weight of male was higher (1.14 kg) then female (1.06 kg). Total litter size production in the 1st, 2nd and 3rd parity was 1.22, 1.79 and 2.03, respectively. Live weight at kidding in 1st, 2nd and 3rd parity was 15.41, 18.43 and 19.99 kg, respectively. Kid mortality was reduced from 22.2 to 8.16% with the parity. Reproductive and productive performances of Black Bengal goat were better in 3rd parity than that of the 1st and 2nd parity.
