金黄疏肝应激散对靶动物草鱼的安全性试验

Safety of Jinhuang Shugan stress powder on target animal in grass carp

为评价金黄疏肝应激散对靶动物草鱼(Ctenopharyngodon idella)的安全性,选择健康草鱼进行养殖试验,分别为对照组和低剂量、中剂量、高剂量3个试验组,饲养3周,观察各组摄食及活动行为,测定各组生长性能指标、血液生理生化指标,剖检试验动物做组织切片。结果表明,各试验组鱼的摄食、呼吸、游动和外观均无异常变化。添加金黄疏肝应激散低、中剂量试验组平均增重率与对照组相比有一定的提高,但差异不显著(P>0.05),高剂量试验组的增重与对照组相比差异不显著(P>0.05)。血液生化指标和组织病理切片结果表明,金黄疏肝应激散对草鱼的健康没有产生影响,金黄疏肝应激散在饲料中添加使用对草鱼是安全的。

In order to evaluate the safety of Jinhuang Shugan stress powder to Ctenopharyngodon Idella,healthy Ctenopharyngodon Idella were selected and divided into 4 groups for culture experiment:control group,low dose group,middle dose group and high dose group.After 3 weeks,the feeding and activity of each group were observed,and the growth performance,blood physiological and bio⁃chemical indexes were determined.The results showed that there were no abnormal changes in feeding,respiration,swimming and ap⁃pearance.Compared with the control group,the average weight gain rate of the low-and middle-dose test group was increased,but the difference was not significant(P>0.05),and there was no significant difference in weight gain between the high dose test group and the control group(P>0.05).The results of blood biochemical indexes and histopathology showed that Jinhuang Shugan stress powder had no effect on the health of grass carp,and Jinhuang Shugan stress powder was safe for Ctenopharyngodon Idella when added to feed.
