Abstract: [Objective] The experiment was conducted to study the effects of bamboo-leaf-flavonoid on the immune function and growth performance in immunosuppression broilers. [Method] In the present work, 120 1-day-old AA female broilers were randomly divided into four groups, and each group contained 3repeats. All of the broilers were fed basal diet. Besides, group 1was treated with cyclophosphamide, group 2with bamboo-leaf-flavonoid and cyclophosphamide, and group 3with bamboo-leaf-flavonoid. All broilers were raised for 35 days. [Results] Bamboo-leaf-flavonoid could promote the health and growth of immunosuppression broilers. The index of bursa of fabricius in the group 2was extremely significant higher than that in group1 at 35 days (P<0.01). Bamboo-leaf-flavonoid could extremely significant improve antibody levels of avian influenza and Newcastle disease in immunosuppression broilers (P<0.01). [Conclusion] The bamboo-leaf-flavonoid could improve the performance and immune function in the immunosuppression poultry.
