ABSTRACT
In this study sixty three farmers mainly from land-less and small category, having some previous experience of rearing goats were selected. There were three genetic groups viz. I) jamunapari male × black bengal female ii) selected black bengal male × selected black bengal female and iii) random black bengal. Feeding and management systems of keeping goats were almost similar. No extra inputs were provided to them except grazing from morning to evening. The main objective of this study was to investigate the effect of selection and crossbreeding in black bengal goats on various reproductive characteristics. Traits considered for the present study were age at puberty, number of services per conception, gestation length, litter size, age at first kidding, post partum heat period, kidding interval, abortion rate and survival rate of kids. Analysis of variance indicated a highly significant (p<0.01) effect of genetic groups on post-partum heat period, kidding interval and abortion rate. Gestation length was significantly (p<0.05) affected by genetic groups. Age at puberty, number of services per conception, litter size, age at first kidding and survival rate were not affected significantly (P>0.05) by genetic groups.
