三种中药复方对鲤幼鱼生长及免疫性能的影响

本试验研究了灌服三种复方中药水煎剂后鲤鱼生长、免疫以及血液生化指标的变化.选用健康1龄鲤鱼,按平均体重分四组,每组40尾,设置两个重复在相同条件下喂养.连续灌服中药28 d后采样检测各项指标.结果表明,三个灌服中药组鲤鱼的增重率均比对照组有显著的提高.方剂AH、AB在有细菌性抗原侵入时能提高血清中总蛋白(TP),白蛋白...

Effect of three kinds of Chinese herbal compound on growth and immunity of Cyprinus carpioio

Effects of three kinds of Chinese herbal compound(PESM) on growth,immunity and blood biochemical indicator of Cyprinus carpio were studied.A total of 160 fingerlings were divided into four groups.Two repeats were contained in one group.We investigated the growth,immunity and biochemical indices of Cyprinus carpio after feeding the Cyprinus carpios with PESM continuously for 28 days.The results showed that testing groups exhibited an apparent increase in the weight growth rate compared to control group.It was found that formula AH and AB could increase the concentration of TP,ALB and GLU when bacterial antigen invades.As for AKP concentration,AH group appears to be increased significantly in all the situations.For the indices of liver function,all these three formulas could reduce the concentration of ALT and AST obviously while only formula AH can also reduce the concentration of LDH.In addition,formula CD could significantly increase the concentration of BUN and CREA as well as the blood sugar concentration;formula AH and AB could give a significant rise to the concentration of Fe in serum.The content of Complement 3 and Complement 4 were both increased significantly by three kinds of PESM compared with the control groups.For NO and NOS,the findings showed a larger difference between the organizations.The contents of NO and NOS in serum of Cyprinus carpios feed with Chinese herbal compound were significantly higher than them in control groups.However,in liver,only the contents of iNOS presenced the same change when bacterial antigen were injected.This work demonstrated that these three formula compounds can facilitate the growth of Cyprinus carpio as well as improve its immune system.
