[Methods] Three kinds of compound Chinese medicines (respectively called A, B and C) were added into basic material feed as feed additives, continuous fed 1 ^+ age Acipenser schrenckii for 35 d, then weight gain rate was determined and superoxide dismutase (SOD) activity, malondialdehyde (MDA) content, total antioxidant capacity (T-AOC) and glutathione peroxidase (GSH-PX) activity in serum and liver were detected. [ Results ] Chinese medicine formulae could increase the superoxide dismutase (SOD) activity, total antioxidant capacity (ToAOC) and glutathione per- oxidase (GSH-PX) in serum and liver of sturgeon. Especially SOD enzyme activity of serum in the three formulae groups was significantly higher ( P 〈 0.05) than control group, SOD enzyme activities of fish liver in group A and C were significantly higher ( P 〈 0.05) than control group; T-AOC activities of serum and liver in the three formulae groups were both incressed, but had no significant differences with that of the control group; only GSH-PX activities of fish serum in group B and C had significant differences (P〈0.05) with that of control group, GSH-PX activities of liver in the three formulae groups had no significant differences with that of control group; and traditional Chinese medicine could significantly reduce malondialdehyde (MDA) content of sturgeon serum, MDA contents of serum and liver in three formulae groups had significant differences (P 〈 0.05) with that of control group. [ Conclusion] The selected three kinds of compound Chinese medicine additives had different degree of ability to improve sturgeon antioxidant function.展开更多
