Abstract: 【Objective】 This experiment was conducted to study the effects of different levels of cassava meal on production performance,serum biochemical parameters,and immune indexes of Wenchang chickens. 【Method】 A total of 600 eighty-one-day-old healthy female Wenchang chickens were randomly divided into 5 groups with 6 replicates per group and 20 chickens per replicate.Chickens were fed diets supplementing 0(CM0),5%(CM5),10%(CM10),20%(CM20),and 25%(CM25) cassava meal,respectively.The trial period lasted for 40 days.The experimental chickens were weighted on the end of the experiment and the growth performance was calculated. Two chickens’ serum in per replicates were collected for the measurement of serum biochemical indicators and serum immune indexes,and slaughter performance and organ coefficients were measured after slaughter. 【Result】 ①Compared with CM0 group,daily gain of Wenchang chickens in CM10,CM20 and CM25 groups was significantly increased (P<0.05),while the ratio of feed to gain were significantly decreased (P<0.05).②Supplementing different levels of cassava meal had no significant effects on slaughtering performance and organ coefficients of Wenchang chickens (P>0.05).③Compared with CM0 group,serum glucose levels of Wenchang chickens in CM20 and CM25 groups were significantly increased (P<0.05);Serum glutathione peroxidase content of Wenchang chickens in CM20 group was markedly increased in comparison to CM0 group (P<0.05). Compared with CM0 group,the serum immunoglobulin A content of Wenchang chickens in CM5 group was significantly increased (P<0.05),but serum tumor necrosis factor-α content of CM25 group was significantly decreased (P<0.05). 【Conclusion】 Supplementing appropriate amount of cassava meal could improve production performance of Wenchang chickens,and improve the glyco metabolism as well as antioxidant properties.Therefore,it was recommended that the appropriate level of cassava meal in the diets of Wenchang chickens aged from 81 to 120 days was 20%.
