氯化胆碱、肌醇和胆汁酸对鲤鱼生长、血清生化及免疫指标的影响

在基础饲料中分别添加氯化胆碱、肌醇和胆汁酸,以基础饲料为对照组饲喂鲤鱼,观察抗应激添加剂对鲤鱼生长性能、血清生化指标和血清非特异性免疫指标的影响。经过60d的饲喂试验,结果表明:①3种物质的添加均有良好的促生长效果,其中氯化胆碱组、肌醇组和胆汁酸组的增重率与对照组相比显著提高(P<0.05),饲料系数与对照组相比显著降低(P<0.05);②3种物质中,肌醇和胆汁酸的添加对提高鲤鱼的免疫力作用更明显,其中肌醇能显著提高血清碱性磷酸酶(ALP)、溶菌酶(LSZ)和超氧化物歧化酶(SOD)的活性(P<0.05),显著降低血清天门冬氨酸转氨酶(AST)的活性(P<0.05);胆汁酸的添加可以显著提高溶菌酶(LSZ)的活性(P<0.05),显著降低丙氨酸转氨酶(ALT)和天门冬氨酸转氨酶(AST)的活性(P<0.05);氯化胆碱的添加可以显著降低鲤鱼血清丙氨酸转氨酶(ALT)活性(P<0.05)。

The effects of choline chloride, inositol and bile acid on growth performance,biochemical and immune indexes of carps

Carps were fed with basal diet containing choline chloride,inositol and bile acid respectively for 60 days.The growth performance, non-specific immune function and biochemical indexes of carps were determined respectively. Results showed that: ①The three substances to the diet had a significant growth-promoting effect.Compared with control group, the weight gain were increased significantly and feed coefficient were decreased significantly (P<0.05). ②Inositol and bile acid played an obvious role in improving immunity. Compared with control, the activities of ALP, LSZ and SOD were increased signifi-cantly by adding inositol. The AST content of blood serum were decreased significantly by adding inositol(P<0.05). Compared with control, the LSZ activities were increased significantly by adding bile acid. The ALT and AST content of blood serum were decreased significantly by adding bile acid(P<0.05). The ALT content of blood serum were decreased significantly by adding choline chloride (P<0.05).
