摘　　要：用添加蛭弧菌的饲料喂养草鱼,能够显著加快草鱼的生长发育,降低饵料系数。同时明显影响各项免疫指标,胸腺的免疫器官指数逐渐升高,头肾的免疫器官指数开始时升高然后下降,血液中的NBT阳性细胞数量逐渐增加, 36d内相对生长率可提高32. 6%。用温和气单胞菌疫苗免疫后,草鱼的免疫应答水平明显提高,免疫力增强。蛭弧菌适宜的添加剂量为0. 5%。The research indicated that the feed with additive of Bdellovibrio bacteriovorus could significantly fasten growth and development of Ctenopharyngodon idellus, lower feed coefficient and markedly affect varieties of immune indexes; the immune organ index of thymus raised gradually, the immune organ index of head kidney increased initially and then decreased, the amount of NBT-positive cells increased gradually, and the relative growth rate in 36 days could increase by 32.6%. The immune response level of Ctenopharyngodon idellus was improved apparently and the immunity was enhanced after inoculation with single cell bacterium vaccine. The appropriate addition dose was 0.5%.
