Present study was undertaken to ascertain the improvement of reproductive performances through selective breeding. Reproductive data of 339 Black Bengal goats comprising of 2 genetic groups namely selective mating group and random mating group was recorded during the year 2004-05 and 2005-06. The study was conducted in 3 adopted villages namely Hatikanda, Ganguria and Panchpota villages in the Nadia district of West Bengal state of India under All India Coordinated Research Project on goat improvement, Black Bengal Field Unit. It was observed that effect of years, villages or genetic groups on age at first mating, age at first kidding, service per conception, weight at first mating, gestation period, service period and kidding interval was nonsignificant while effect of selection was significant (p<0.05) on weight at first kidding. The does of the selective group came on heat, served and kidded early during the year 2005-06 in comparison to the previous year. The kidding interval as well as service period was also decreased among the goats of selective group and service required per conception was also less. The body weight at first kidding of Black Bengal does of selective group was higher than random mating group during 2005-06. The reproductive efficiency was improving through selective breeding of Black Bengal goat under field condition. Indication of the result of present study was justifying the selection process as well as effectiveness for conservation of Black Bengal goat in their home tract. |
