Abstract: This experiment aims to investigate the effects of Chinese herbal medicine on the growth performance， immune organ indices， slaughter performance， serum biochemical indicators， reproductive hormones， immunoglobulins，antioxidant performance，egg ? laying performance，and egg quality of Wenchang broilers hens during the growing period and to enhance the physical reserve of Wenchang meat breeding chickens during the 13-20 week growing period. 540 healthy Wenchang broilers hen breeders at 13 weeks of age with similar body weight were randomly divided into 6 groups，with 6 replicates in each treatment group and 15 chickens in each replicate. The control group was fed with the basic diet. The treatment groups included the POL group（basic diet + 0.1% POL powder），the TG group（basic diet +0.1% TG powder），the RSF group（basic diet +0.1% RSF powder），the PS group （basic diet +0.1% PS powder），and the TFU group（basic diet +0.1% TFU powder）. The experimental period was 7 weeks. The 20?week?old body weight，average weekly body weight and the weight at the beginning of egg production of Wenchang chickens in the POL group and the TG group were significantly higher than those in the CON group，while the feed conversion ratio was significantly lower than that in the CON group（P<0.05）. The leg muscle rate and yolk color of Wenchang chickens in the POL group were significantly higher than those in the CON group and the PS group （P<0.05）. The abdominal fat rate，intermuscular fat width and serum MDA content of Wenchang chickens in the RSF group and the TFU group were significantly lower than those in the CON group（P<0.05）. The abdominal fat rate of the RSF group in Wenchang chickens was significantly lower than that of the TG group（P<0.05）. The bursa index of the PS group in Wenchang chickens was significantly higher than that of the CON group and the TG group（P<0.05）. The albumen height and Haugh unit of Wenchang chickens in the TG group，RSF group，PS group and TFU group were significantly higher than those in the CON group（P<0.05）. The serum ALB levels of the TG group and the PS group in Wenchang chickens were significantly higher than those of the CON group and the RSF group（P<0.05）. The level of serum TG in the TG group of Wenchang chickens was significantly lower than that in the CON group，the POL group and the RSF group，while the spleen index in the TG group was the opposite（P<0.05）. The levels of serum IgG and E2 in Wenchang chickens in the POL group，TG group and RSF group were significantly higher than those in the CON group（P<0.05）. The activity of serum GSH?Px in the TG group and the PS group of Wenchang chickens was higher than that in the CON group，while the activity of serum GSH?Px in the TG group was significantly higher than that in the POL group，the RSF group and the TFU group（P<0.05）. The activity of serum T?AOC in the POL group of Wenchang chickens was significantly higher than that in the CON group and the TFU group（P<0.05）. Studies have shown that POL and TG can improve the growth performance of Wenchang chickens，enhance their serum reproductive hormones，immunity and antioxidant capacity，while RSF，TFU and PS can improve the slaughter performance and egg quality of Wenchang chickens.
