Morphometric features and performances of Black Bengal goat in Bangladesh.

Black Bengal goat (BBG) is the most adaptable, widely distributed, and prominent goat breed in Bangladesh, well known in the world for its high prolificacy, low demand of feed, tolerance to harsh weather conditions, and disease resistance with remarkably good quality red meat and skin. A large number of indiscriminate research reports on BBG have been published; however, the review on the productive and reproductive performances with different physiological features of BBG in Bangladesh is scarce. This review was conducted to investigate and summarize the available research reports on BBGs to highlight the gaps and provide coherent recommendations for the future research plan for sustainable BBG production in Bangladesh. It covers research works in morphometric features, feeding and nutrition, reproduction, diseases and health management, husbandry practices, and production performances of BBG under local conditions. Due to the contemporary increased demand for animal protein (meat and milk), the scope of small ruminants, especially goat farming, increases with other large ruminants farming. The key constraints of BBG production in Bangladesh include higher disease prevalence with low or no management practices, kid mortality, inadequate feeds and fodder supply, and poor marketing channel with some other stumpy genetic potentialities (slower body weight gain, low milk production) of this goat. Future research would be required to assess the contribution of BBG to household economies and food securities throughout the year and evaluate the constraints, adaptation and extension of artificial insemination (AI), and genetic improvement of economically important traits using molecular techniques and the selective breeding program.
