Abstract:

The present study was conducted to know the productive and reproductive performance of Black Bengal goats in relation to different coat colors. A total of 609 Black Bengal goats were selected from 35 private owned farms in Sylhet division during November 2017 to October 2018. Average birth weight and adult body weight gain after 12 months of white, solid black, black with Dutch belt spotting, and brown bezoar coat color goats were varied significantly. Birth weight is high in black with Dutch belt spotting coat and the adult weight gain after 12 months is high in solid black coat color. The average daily milk yield and the average lactation period of white, solid black, black with Dutch belt spotting, and brown bezoar coat color goats were varied significantly. The age at puberty varied according to the coat color. The age of first kidding of white, solid black, black with Dutch belt spotting and brown bezoar coat color goats did not vary significantly. The average gestation period in 1st parity, age at first conception and post-partum estrous of Black Bengal goat were not affected by the coat colors. Number of litter per kidding was higher in solid black i.e. the reproductive performance is better in solid black coated goats than that of other coat colors. From the present study, it may be concluded that the performances of solid black color goats were better than other coat colors in terms of adult weight of does, daily milk yield, lactation period, age at puberty, service per conception and litter size.
