AB  - The study was conducted to know the productive and reproductive traits of goats, estimates their
genetic association and selection of the superior does. Data was collected from 170 goats of Jamunapari, Black
Bengal and their cross (Jamunapari×Black Bengal) from the rural and Metro Politian areas of Bangladesh. The
Economic Values (EVs) of different traits and profitability per doe per year were estimated using a linear model
and Breeding Values (BVs) by animal model. Selection index was constructed as the sum of the product of BVs
with the EVs of each trait. Jamunapari goat produced higher daily milk yield (0.65-0.68 kg) than Black Bengal
and crossbred. Birth weight (1.68-1.86 kg) and liveweight (32-35 kg) of Jamunapari does were higher than other
breeds but the litter size (2) and kidding interval (158-168 days) of Black Bengal goats were better. Heritability,
genotypic and phenotypic correlations of all traits were positive for all breeds except liveweight and kidding
interval was negative. The profitability of Black Bengal goats was higher than other breeds due to its regularity
of kidding and larger litter size. Finally, according to the selection index the highest ranking does were selected
as parents for the production of offspring.
