A study was conducted in 2022 in the Liban Jawi district to characterize the breeding practices of indigenous chickens. A total of 192 farmers were surveyed, revealing diverse breeding objectives, including income generation, egg consumption, savings, and meat consumption. Limited selective breeding was observed, with plumage color, egg number, broodiness, hatchability, and male body weight as common selection traits. Most farmers practiced uncontrolled natural mating and were unaware of the risks of inbreeding. Culling underproductive chickens, undesirable colored cockerels, or pullets at an early age, along with selling or slaughtering, were employed to prevent unwanted mating. Correspondence Analysis (CA) revealed significant relationships among phenotypic traits, with Dimension 1 accounting for 39.43 % of total inertia, indicating that environmental conditions heavily influence trait selection. The Chi-Squared Distance analysis highlighted strong preferences for Egg Number (D= 15.23) and Hatchability (D = 12.45), both showing highly significant P-values (p = 0.001 and p = 0.002 respectively). Additionally, farmers expressed significant preferences for Disease Resistance (D = 11.56, p = 0.003) and Body Size (D = 10.12, p = 0.012). This research provides valuable insights into the breeding practices of indigenous chickens in the unique context of the Liban Jawi District, Ethiopia. By combining qualitative and quantitative analyses, the study emphasizes the significance of indigenous knowledge, identifies challenges, and underscores the implications for sustainable rural livelihoods. The findings advocate for effective trait selection and the implementation of controlled mating systems to mitigate inbreeding risks and enhance productivity in indigenous chicken populations.
2022年在利班贾维地区开展了一项研究,以描述当地土鸡的养殖方式。共对192名农户进行了调查,结果显示养殖目标多样,包括创收、食用鸡蛋、储蓄以及食用鸡肉。观察到有限的选择性育种,羽毛颜色、产蛋数、抱窝性、孵化率和公鸡体重是常见的选择性状。大多数农户采用不受控制的自然交配,且未意识到近亲繁殖的风险。淘汰低产鸡、不理想毛色的公鸡或过早淘汰小母鸡,并通过售卖或屠宰来防止不必要的交配。对应分析(CA)揭示了表型性状之间的显著关系,第一维度占总惯性的39.43%,表明环境条件对性状选择有很大影响。卡方距离分析突出了对产蛋数(D = 15.23)和孵化率(D = 12.45)的强烈偏好,两者的P值均极显著(分别为p = 0.001和p = 0.002)。此外,农户对抗病性(D = 11.56,p = 0.003)和体型(D = 10.12,p = 0.012)也表现出显著偏好。本研究为埃塞俄比亚利班贾维地区独特背景下的当地土鸡养殖方式提供了有价值的见解。通过定性和定量分析相结合,该研究强调了本土知识的重要性,识别了挑战,并强调了对农村可持续生计的影响。研究结果主张进行有效的性状选择并实施可控交配系统,以降低近亲繁殖风险并提高当地土鸡种群的生产力。
