Abstract

The aim of the study was to identify the breeding objectives and selection criteria of farmers for indigenous chickens in southern region of Ethiopia. Data were subjected to GLM procedures of Statistical Analysis System (SAS 2012, ver. 9.4) by fitting zones as independent variable to analyze the chicken population composition. Moreover, ranking analyses were used for computing data on breeding objective and selection criteria of indigenous chicken. Indexes were used to calculate data collected from rankings using weighed averages. Hens and chicks showed significantly (p<0.05) higher in number for Wolaita; however, the number of cockerels is significantly (p<0.05) higher in Hadiya followed by Wolaita zone. The results of this study suggested that farmers have different breeding objectives for their chicken. Across all the three studied zones, egg production was ranked first; however, rearing chickens for the cultural purpose is documented as less across all the three studied zones of the southern Ethiopia. The selection criteria used for selection of breeding hen; egg number, plumage color, hatchability, broodiness and egg size were the traits of highest importance for selection purpose with an index values of 0.365, 0.129, 0.129, 0.120 and 0.102 respectively. The highest selection criteria used to select breeding cock were body size, growth rate, plumage color and comb type. Development of a breeding programs for improvement of indigenous chicken strains should focus on the traits prioritized by farmers because of breeding goals developed without considering the needs of all the stakeholders have high chances of failerity by end users.
埃塞俄比亚南部土鸡生态型的育种目标和农民的看法
本研究旨在确定埃塞俄比亚南部地区农民饲养土鸡的育种目标和选择标准。数据采用统计分析系统(SAS 2012,9.4 版)的 GLM 程序,将地区作为自变量来分析鸡的种群组成。此外,还使用了排序分析来计算土鸡育种目标和选择标准的数据。使用指数来计算从排名中收集的数据,使用的是称重平均值。Wolaita 地区的母鸡和雏鸡数量明显较多(P<0.05);然而,Hadiya 地区的公鸡数量明显较多(P<0.05),其次是 Wolaita 地区。研究结果表明,养殖户的养鸡目标各不相同。在所研究的三个地区中,产蛋量都排在第一位;然而,在埃塞俄比亚南部所研究的三个地区中,为文化目的而饲养鸡的记录较少。用于挑选种母鸡的选择标准中,鸡蛋数量、羽毛颜色、孵化率、育雏能力和鸡蛋大小是最重要的性状,指数值分别为 0.365、0.129、0.129、0.120 和 0.102。体型、生长速度、羽色和梳型是选择种公鸡的最高标准。为改良土鸡品系而制定的育种计划应侧重于农民优先考虑的性状,因为不考虑所有利益相关者需求而制定的育种目标很有可能会被最终用户淘汰。
