Abstract 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.
