Abstract

ABSTRACT Ethiopia’s 60 million chickens are reared primarily in free range, smallholder systems. Therefore, upgrading smallholder poultry to small-scale commercial systems is central to rural development. With the aim of providing access to improved chicken by rural farmers in Ethiopia, the live body weight at week 17 and number of eggs per bird per week for one locally improved and three tropically adapted dual-purpose chicken strains was tested through a project called the African Chicken Genetic Gains. Both traits were analyzed by fitting a linear mixed model with week and pen as random effects, and station and breed as fixed effects. The result showed that both breed and station effects were significant for both traits. The introduced breeds performed better than the local improved breed for both traits. Thus, the introduction of system-appropriate high-yielding tropically adapted breeds has the potential to increase the productivity of chicken.

埃塞俄比亚引进鸡和地方鸡的活体重和产蛋量的评价

埃塞俄比亚的6000万只鸡主要是在自由放养的小农系统中饲养的。因此，将小农家禽升级为小规模商业系统对农村发展至关重要。为了向埃塞俄比亚农村农民提供改良的鸡，通过一个名为“非洲鸡遗传增益”的项目，对一种当地改良的和三种热带适应的双用途鸡品种的第17周活体重和每周每只鸡的蛋数进行了测试。以周和栏为随机效应，工位和品种为固定效应，拟合线性混合模型对两种性状进行分析。结果表明，这两个性状的品种效应和站位效应均显著。引进品种在这两个性状上均优于地方良种。因此，引进适合系统的高产热带适应品种有可能提高鸡的生产力。
