Abstract：2 weeds old male and female AA broilers with the number of 75 respectively were se-lected in order to investigate the reason of differences in production performance between male and female. Production performance was observed at the age of 4 and 6 weeks old by detecting 17 blood indexes such as growth hormone using ELISA. The results indicated that daily feed intake(AD-FI), daily gain(ADG), and feed/gain ratio of male were extremely significant higher than female(P<0.01).Blood EPI, NE, TSH, GH, IGF-Ⅰand T4 in male were higher than that in female at 4 weeks old, while LP, T3 and INS were lower, among which T3 and INS were significance lower than femal broilers (P<0.01). ACTH and NE in 6 week old male birds were higher than female, and NE was in signifi-cance level. There were significant differences in other indexes.
