[Method]About 180 female Wenchang chickens were divided into five groups at random with three repetitions for every group and twelve chickens for a repetition. Group 1 was control group and the chickens were fed with basic forages; the 2nd group was control group of antibiotics and the chickens were fed with basic forages and 600 mg /kg of aureomycin; group 3,4 and 5 contained 0. 1%,0. 2% and 0. 3% of the additives respectively,besides basic forages. Chickens at average weight were chosen six from every group on 35th and 56th days,respectively, to prepare serums for biochemical indices of bloods and analyze effects of additives on the indices. [Result]Serum cholinesterase activity and albu- min content were both improved by 0. 1%,0. 2% and 0. 3% of the additives （ P 〈0. 05） ; activity of alkaline phosphatase was enhanced,and serum cholesterol was lowered both by 0. 2% and 0. 3% of the additives （ P 〈0. 05） . [Conclusion]Additives of traditional Chinese medicines have an ac- tive effect on blood biochemical indices of Wenchang chickens.展开更多
