ABSTRACT The data on 837 birds representing five crosses (Aseel x PD-1, Aseel x PD-2, Aseel x PD-6, Aseel x PB-1 and Aseel x PB-2) survived up to 12 weeks of age were evaluated for various growth, meat quality, meat composition, sensory attributes and carcass traits as an alternative to native chicken farming. Body weights and shank lengths significantly (P≤0.05) differed at all ages. Aseel crosses with coloured broiler lines (PB-1 and PB-2) had significantly (P≤0.05) higher body weights while Aseel x PD-1 cross recorded higher shank length at all ages. The fat and ash proportion varied significantly (P≤0.05) among the crosses. The pH values of the breast meat ranged 5.89 to 6.29. The Shear force values (SFV) and Hydroxyproline (HP) concentration differed significantly (P≤0.05) among the crosses. Meat colour differed significantly (P≤0.05) with respect to yellowness (b*) and red (a*) colouration. The proportion of legs, wings, back, neck, meat and bone significantly (P≤0.05) differed among the crosses. The cluster analysis of means of all traits revealed that least distance exists between Aseel x PD-1 and Aseel x PD-6. The study concludes that, Aseel x PD-1 and Aseel x PD-6 crosses may be a viable and suitable alternative for native chicken farming.

适合小规模集约化肉鸡养殖的Aseel杂交种生长、胴体和肉质性状研究

摘要 对代表 5 个杂交（Aseel x PD-1、Aseel x PD-2、Aseel x PD-6、Aseel x PB-1 和 Aseel x PB-2）的 837 只鸡的数据进行了评估，这些鸡存活至 12 周龄各种生长、肉质、肉成分、感官属性和胴体特征，作为本地养鸡的替代品。体重和小腿长度在所有年龄段都有显着差异（P≤0.05）。与有色肉鸡品系（PB-1 和 PB-2）杂交的 Aseel 具有显着（P≤0.05）更高的体重，而 Aseel x PD-1 杂交在所有年龄段都记录了更高的小腿长度。杂交种间脂肪和灰分比例差异显着（P≤0.05）。胸肉的 pH 值范围为 5.89 至 6.29。剪切力值 (SFV) 和羟脯氨酸 (HP) 浓度在杂交之间存在显着差异 (P≤0.05)。肉色差异显着（P≤0. 05) 关于黄色 (b*) 和红色 (a*) 着色。腿、翅、背、颈、肉和骨的比例在杂交之间存在显着差异（P≤0.05）。所有性状均值的聚类分析表明，Aseel x PD-1 和 Aseel x PD-6 之间存在最小距离。该研究得出的结论是，Aseel x PD-1 和 Aseel x PD-6 杂交可能是本地养鸡业可行且合适的替代方案。
