Rhode Island Red (RIR) and Fayoumi chickens were evaluated on-station in a college farm and on-farm in village farms, whereas local chickens were only tested under on-farm condition. Traits recorded are egg production and egg quality, body weight and feed efficiency at 4, 8 and 12 months of age. Significant age effect was found for most traits except for shell thickness, albumen height and egg length. Also, significant breed by management system interactions were found for all traits measured in both systems. Fayoumi chickens were higher in egg production in both management systems. Moreover, they were higher than RIR in feed efficiency. RIR were higher in most egg quality traits and had higher weight gain. Local chickens performed below the two exotic breeds in most of the traits, but had higher weight gain than Fayoumi. Chickens kept on-farm had poorer performance than those kept on-station in all traits except for yolk colour.
罗德岛红鸡（RIR）和法尤米鸡在大学农场进行了场内评估，并在乡村农场进行了农场实地评估，而本地鸡仅在农场实地条件下进行了测试。记录的性状包括产蛋量和蛋品质、4、8和12月龄时的体重和饲料效率。除了蛋壳厚度、蛋白高度和蛋长外，大多数性状都发现了显著的年龄效应。此外，在两个系统中测量的所有性状都发现了品种与管理系统之间的显著交互作用。在两种管理系统中，法尤米鸡的产蛋量都更高。此外，它们的饲料效率高于罗德岛红鸡。罗德岛红鸡在大多数蛋品质性状上更高，体重增加也更多。本地鸡在大多数性状上的表现低于这两个外来品种，但体重增加比法尤米鸡高。除了蛋黄颜色外，在所有性状上，农场饲养的鸡的表现都比场内饲养的鸡差。
