chinois. 为了研究解耦联蛋白基因(uncoupling protein，UCP)对鸡(Gallus gallus)初生重及活性氧含量的影响，本实验通过对3个品种鸡初生重、UCP C353T多态位点基因型以及肌肉组织活性氧(ROS)含量的测定，发现丝羽乌鸡ROS值显著低于白莱航、寿光鸡，UCP TT基因型ROS值显著高于CT和CC基因型， 而ROS含量与雏鸡初生重之间存在着正向的相关性(r=0.5011)，UCP TT基因型的初生重显著高于CT和CC基因型。实验结果揭示了鸡UCP基因型对初生重性状具有选择效应。

In order to explore the effect of uncoupling protein gene (UCP) on birth weight and content of reactive oxygen species(ROS) in chickens (Gallus gallus), the birth weight, UCP C353T mutation genotyping and muscle ROS contents from three chicken breeds were analyzed. The results indicated Silky chicken had higher ROS contents than that of White Leghorn and Shouguang chickens, and ROS contents for genotype TT of UCP appeared notably higher than that of CT and CC genotypes. ROS contents presented a positive correlation with chicken birth weight(r=0.5011). The birth weight for genotype TT of UCP demonstrated notably higher than that of CT and CC genotype. The findings showed UCP genotypes can impact chicken birth weight for selections.
