The aims of current investigation were to study the growth performance, carcass traits, meat quality and expression profile of (), (), () and () genes in three commercial broiler strains including Ross (Ross 308), Cobb (Cobb 500), and Arian in 2023. A total number of 240 one-day-old chicks were reared under an equalized standard management condition for 6 weeks. Performance, organ weights, meat quality and the expression level of the myogenic genes in the pectoral muscle were investigated. The lowest body weight (BW), feed intake, weight gain and highest feed conversion ratio (FCR) was observed for Arian at the end of the study. The meat quality was similar between strains. The expression level was significantly higher on 42 days of age in Cobb compared to Ross and Arian. The expression level was significantly higher on 28 days of age in Cobb compared to Ross. The expression level was significantly lower in Arian compared to Cobb on 42 days of age. Furthermore, the expression level was significantly lower in Cobb compared to Ross and Arian on 42 days of age. The remarkable differences in gene expression levels at the end of the rearing period was supported by higher growth performance and BW of Cobb compared to Ross and Arian strains. In conclusion, the findings of current study could conveniently help assess the performance of these broiler strains under similar rearing condition.
当前研究的目的是在2023年研究罗斯（罗斯308）、科宝（科宝500）和阿里安这三个商业肉鸡品系中（）、（）、（）和（）基因的生长性能、胴体性状、肉质和表达谱。总共240只一日龄雏鸡在均衡的标准管理条件下饲养6周。研究了生长性能、器官重量、肉质以及胸肌中肌源性基因的表达水平。在研究结束时，阿里安的体重（BW）、采食量、体重增加最低，饲料转化率（FCR）最高。各品系之间的肉质相似。与罗斯和阿里安相比，科宝在42日龄时（）的表达水平显著更高。与罗斯相比，科宝在28日龄时（）的表达水平显著更高。在42日龄时，阿里安的（）表达水平显著低于科宝。此外，在42日龄时，科宝的（）表达水平显著低于罗斯和阿里安。与罗斯和阿里安品系相比，科宝在饲养期结束时更高的生长性能和体重支持了基因表达水平的显著差异。总之，当前研究的结果可以方便地帮助评估这些肉鸡品系在相似饲养条件下的性能。
