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.
孟加拉邦的黑色孟加拉羊(BBG)是最适应环境、分布最广、最为突出的山羊品种,以高产、低饲料需求、能耐受恶劣天气条件和抗病能力以及优质的红色肉类和皮肤而闻名于世。已经发表了大量关于 BBG 的无差别的研究报告,但对于孟加拉国 BBG 不同生理特征的生产性能和繁殖性能的综述却很少。进行本次综述是为了调查和总结关于 BBG 的现有研究报告,以突出差距,并为孟加拉国可持续的 BBG 生产未来研究计划提供一致的建议。它涵盖了形态特征、饲养和营养、繁殖、疾病和健康管理、饲养实践以及 BBG 在当地条件下的生产性能方面的研究工作。由于当代对动物蛋白(肉类和牛奶)的需求增加,小反刍动物(尤其是山羊养殖)的范围随着其他大反刍动物养殖的增加而扩大。孟加拉国 BBG 生产的主要限制因素包括疾病流行率较高但管理不善、幼畜死亡率高、饲料和饲料供应不足以及营销渠道不畅,以及这种山羊的一些其他遗传潜力较差(体重增长缓慢、产奶量低)。未来的研究需要评估 BBG 对全年家庭经济和粮食安全的贡献,并评估限制因素、人工授精(AI)的适应和推广,以及使用分子技术和选择性育种计划对经济重要性状的遗传改良。
