Abstract

The study was conducted in Adami Tulu Jidokombolcha, Bora, Dodola, Shala and Negele-Arsi districts with the objective of assessing cattle breeding practices and the rate of inbreeding. Two hundred forty respondents were identifi ed using random sampling techniques. The study’s results indicated that farmers traditionally use names and ear cuts to identify their local cattle. Body size was ranked as the primary selection criteria for bulls, while reproductive fi tness and milk yield traits were primordial selection criteria for cows. Many of the respondents rear bulls for draught purposes, while few of them rear them for breeding purposes. The study indicated that breeding was mostly panmectic as most of the bulls were owned communally. The fi ndings revealed that the majority of respondents were unaware of the negative effects of inbreeding. Most of the respondents practiced culling of unproductive cattle. Poor reproductive fi tness and milk yield were frequently used as primary culling criteria for cows, while poor draft power and old age were ranked as prime culling criteria for male cattle. The information generated on farmers’ breeding practices should be used as a baseline for future cattle breeding improvement strategy in the studied and similar areas.

埃塞俄比亚奥罗米亚中部裂谷的传统养牛做法和近交率
该研究在阿达米·图鲁·吉多孔博尔查、博拉、多多拉、沙拉和内格勒-阿尔西地区进行,目的是评估牛的育种做法和近交率。使用随机抽样技术确定了240名受访者。研究结果表明,农民传统上使用名字和耳痕来识别他们当地的牛。体型是公牛的主要选择标准,生殖健康和产奶量性状是奶牛的主要选择标准。许多受访者饲养公牛是为了役用,而很少有人饲养公牛是为了繁殖。该研究表明,由于大多数公牛是公有的,因此繁殖主要是panmectic。调查结果显示,大多数受访者没有意识到近亲繁殖的负面影响。大多数答复者实行扑杀非生产性牛的做法。生殖健康状况差和产奶量差经常被用作奶牛的主要淘汰标准,而牵引力差和年龄大则被列为雄性牛的主要淘汰标准。所产生的关于农民育种做法的信息应作为所研究地区和类似地区未来牛育种改进战略的基线。研究论文:埃塞俄比亚奥罗米亚中部裂谷传统牛养殖实践和近交率Aman Gudeto1*, Tadele Mirkena2和Tesfaye Kebede3 1埃塞俄比亚adami Tulu农业研究中心2埃塞俄比亚亚的斯亚贝巴联合国粮食及农业组织3挪威生命科学大学,挪威收稿日期:2021年8月14日接收日期:2021年9月13日发表日期:2021年9月14日*通讯作者:Aman Gudeto, Adami Tulu农业研究中心,埃塞俄比亚,E-mail:
