摘要

埃塞俄比亚是非洲牲畜数量最多的国家。尽管牛的数量最大,但其生产和繁殖性能非常低,生产力是投入和产出之间的关系。关于埃塞俄比亚小农的生殖和生产绩效的信息有限。因此;本审查文件的目的是强调埃塞俄比亚情况下生殖和生产业绩参数的全面方面。繁殖性能是奶牛企业非常重要的一项指标。牛奶的生产在很大程度上取决于生殖活动。生殖性能指标包括单胎服务数(NSC)、产犊间隔(CI)和开放天数(DO)。泌乳长度(LL)、泌乳量(LY)和日产奶量(DMY)是奶牛生产效益的重要指标。在埃塞俄比亚,杂交奶牛主要是瘤牛与荷斯泰因-弗里马杂交,平均繁殖性能如CI和生产性能如LL接近最佳。地方品种繁殖和生产性状的平均值低于弗里西亚及其杂交品种。然而,关于热带地区,特别是埃塞俄比亚的小农、城市和城郊奶牛场奶牛的繁殖和生产性能的信息有限。通过对奶牛的有效管理,可以提高奶牛的生产性能。由此可见,通过改善奶牛的基因组成,有可能提高埃塞俄比亚奶牛的繁殖性能和生产性能。

Review on Reproductive and Productive Performance of Dairy Cow in Ethiopia
Ethiopia has largest livestock population in Africa. Despite the largest cattle population, its productive and reproductive performance is very low productivity is relationship between inputs and outputs. The information about reproductive and productive performance in Ethiopia is limited for smallholder. Therefore; the objective of this review paper was to highlight the overall aspects of reproductive and productive performance parameters under Ethiopian condition. Reproductive performance is a trait of outstanding importance in dairy cow enterprises. The production of milk depends heavily on reproductive activity. Reproductive performance traits include number of service per-conception (NSC), calving interval (CI) and days open (DO). Productive performance traits include lactation length (LL), lactation yield (LY) and daily milk yield (DMY) are important criteria for profitable dairy farming. In Ethiopia, crossbred dairy cattle mainly are crosses of zebu with Holstein-Friesian and the mean reproductive performance like CI and productive performance like LL were near to the optimum. The mean values of reproductive and productive traits lower in case of indigenous breed than Friesian and their crosses. However, information is limited about the reproductive and productive performance of dairy cows in smallholder, urban and peri-urban dairy farms in the tropics, particularly in Ethiopia. With efficient management of cows, it is possible to improve performance traits. It is concluded that by improving genetic makeup of dairy cow it is possible to improve the reproductive and productive performance of dairy cattle in Ethiopia.
