Abstract: In order to examine the rate of Chinese herbal medicine on rate of body weight-gain,death rate,biochemical indicator of blood,and provide reference data for the development, so we added 5 kinds of Chinese herbal medicine in the feed of 1+ age Hucho taimen. There were 30 individuals in each group including experiment groups and a control group, and each had a parallel group, fed diets contained different Chinese herbal medicine or not at rate of 2.0% according to body weight. When the feeding experiment finished, body weight and death rate were counted and the samples were adopted for determining biochemical indexes. The results showed that Glycyrrhiza had better effects on growth, but the effects of Poria cocos were opposite. Except Cyrtomium fortuneian and Poria cocos group, the other groups were no death. The total bilirubin in Cyrtomium fortunei had obvious rise; in licorice low dose group and the Astragalus high dose group, urea nitrogen in serum was obvious rise; remaining several biochemical indicators and controlled group compared to no obvious changes. The experiment results showed that, in different Chinese herbal medicine in feed on blood biochemical indexes of Hucho taimen changes were closely related to types of drug and dosage.
