Abstract

Indigenous chickens play a crucial role in the livelihoods of smallholder farmers in rural Ethiopia. This study aimed to phenotypically characterize indigenous chickens in the Liban Jawi district, focusing on measurements of phenotypic characteristics. The multi-stage sampling method selected 192 households with at least two mature indigenous chickens from 2,166 households, resulting in the sampling of 224 chickens (138 females and 86 males) for phenotypic characterization. Qualitative trait analysis revealed that male chickens exhibited a plain head shape (54.7%), single combs (39.5%), red feather plumage (26.7%), yellow shanks (54.7%), red earlobes (51.6%), and white skin (68.6%). Female chickens showed single combs (75.4%), red earlobes (51.4%), yellow shanks (50.1%), and brown mottled feathers (23.9%), with red (23.1%) and black (9.4%) feathers observed. Quantitatively, cocks had an average body weight of 1.46±0.02 kg, while hens weighed 1.21±0.01 kg. Cocks exhibited larger body dimensions, with significant measurements in body length (38.05±0.26 cm) and wingspan (38.56±0.13 cm). For hens, the average body length was 31.55±0.33 cm. Shank length emerged as a moderate predictor of body weight for both sexes (r = 0.45 for hens and r = 0.44 for cocks), indicating it should be combined with other factors for accurate assessments. Cluster and multivariate analysis revealed distinct phenotypic groupings among the indigenous chickens, highlighting significant variations in both qualitative and quantitative traits. This suggests the potential for improvement through selective breeding at the community level, influenced by unique environmental conditions and practices. These findings provide valuable insights into the phenotypic characterization of indigenous chickens, serving as a foundation for future breeding programs and conservation efforts aimed at enhancing productivity and preserving genetic diversity. Further molecular-level characterization is recommended to validate the current phenotypic results.

摘要

本地鸡在埃塞俄比亚农村小农户的生计中发挥着关键作用。本研究旨在对利班贾维地区的本地鸡进行表型特征描述,重点是对表型特征的测量。多阶段抽样方法从2166户家庭中选取了192户至少有两只成年本地鸡的家庭,从而抽取了224只鸡(138只母鸡和86只公鸡)进行表型特征描述。定性性状分析表明,公鸡表现出平头形状(54.7%)、单冠(39.5%)、红色羽毛(26.7%)、黄色胫(54.7%)、红色耳垂(51.6%)和白色皮肤(68.6%)。母鸡表现出单冠(75.4%)、红色耳垂(51.4%)、黄色胫(50.1%)和棕色斑驳羽毛(23.9%),观察到有红色(23.1%)和黑色(9.4%)羽毛。在数量上,公鸡的平均体重为1.46±0.02千克,而母鸡体重为1.21±0.01千克。公鸡的身体尺寸更大,体长(38.05±0.26厘米)和翼展(38.56±0.13厘米)有显著测量值。对于母鸡,平均体长为31.55±0.33厘米。胫长是两性体重的一个适度预测指标(母鸡r = 0.45,公鸡r = 0.44),这表明应将其与其他因素结合起来进行准确评估。聚类和多变量分析揭示了本地鸡之间不同的表型分组,突出了定性和定量性状的显著差异。这表明在独特的环境条件和养殖方式影响下,通过社区层面的选择性育种有改进的潜力。这些发现为本地鸡的表型特征描述提供了有价值的见解,为未来旨在提高生产力和保护遗传多样性的育种计划和保护努力奠定了基础。建议进一步进行分子水平的特征描述,以验证当前的表型结果。
