摘要

摘要刘建军,刘建军,刘建军,等。埃塞俄比亚南部Dawro区和Konta特区选定地区土鸡的生产系统和饲养实践。农业学报,5:72-83。本研究旨在了解鸡的生产系统、育种实践、选择标准和生产限制,为研究区域未来的生产策略提供基线。数据是通过个人访谈、焦点小组讨论和个人观察收集的。利用粮食及农业组织准则编制的半结构化问卷收集了答复者的意见。根据鸡的数量、生产潜力和道路可达性,我们考虑了来自6个kebeles的90户家庭进行单独访谈。采用SPSS 23.0软件对数据进行分析,并对家畜重要性、养鸡目的、选择标准、扑杀标准、养鸡生产约束条件等各排序变量计算指数。中部农业生态的肉类生产和创收指数分别为0.28和0.26。低洼生态农业的创收指数值和肉类生产指数值分别为0.31和0.25。综上所述,饲养雌鸡和雄鸡主要是为了创收,其次是肉类来源。在育种选择中,一个优先考虑的变量是雄性和雌性鸡的体型和健康状况。大多数应答者在健康状况、产蛋量和年龄方面选择种鸡,指数值分别为0.44、0.36和0.15;而其种鸡在体型、抗病性和颜色上的指数值分别为0.36、0.29和0.28。疾病和捕食者是研究区鸡生产的主要制约因素。因此,解决这些限制对于设计一个成功的遗传改良方案是很重要的。

Production system and breeding practice of indigenous chickens in selected districts of Dawro zone and Konta special district, Southern Ethiopia
Abstract. Melak A, Kenfo H, Aseged T, Hailu A. 2021. Production system and breeding practice of indigenous chickens in selected districts of Dawro zone and Konta special district, Southern Ethiopia. Asian J Agric 5: 72-83. This study was conducted to understand the production system, breeding practices, selection criteria, and production constraints of chickens to have a baseline for future production strategies in the study area. The data was collected through individual interviews, focus group discussions, and personal observations. A semi-structured questionnaire using Food and Agriculture Organization Guidelines was used to avail the views of the respondents. Based on chicken population, production potential, and road accessibility, a total of 90 households from six kebeles were considered for an individual interview. The data was analyzed using SPSS software version 23.0 and an index was calculated for all ranked variables like the importance of livestock, purpose of keeping chicken, selection criteria, culling criteria, and constraints of chicken production. The index value of meat production and income generation in midland agroecology were 0.28 and 0.26 respectively. Also, the index value of income generation and meat production in lowland agroecology were 0.31 and 0.25 respectively. It is concluded that both female and male chickens are maintained mainly for income generation followed by meat sources. A variable that was given a higher priority in breeding selection was body size and health conditions, for male and female chickens respectively. Most of the respondents select their breeding hen in health, egg production, and age with an index value of 0.44 and 0.36 and 0.15 respectively; while their breeding cock in body size, disease resistance, and color with an index value of 0.36, 0.29, and 0.28 respectively. Disease and predators were the major constraints of chicken production mentioned in the study area. Therefore, addressing these constraints is important to design a successful genetic improvement scheme.
