Abstract:

To use the Chinese herbal medicine feed additive in culture of sturgeon, effects of three kinds of Chinese herbal compound on growth and antioxidant defenses of Amur sturgeon (Acipenserschrenckii Brandt) were studied. The three Chinese herbal compounds (compound A, compound B and compound C) were added into the base material as feed additive, and the one-year-old Acipenserschrenckii Brandt were fed with the experimental feed and the basic feed for 35 days. The growth rate of weight was investigated. The activities of SOD, T-AOC, GSH-PX and the content of MDA were measured by the test. The results showed that the Chinese herbal compound could obviously increase the activities of SOD, T-AOC, GSH-PX. In particular, the SOD activity of the serum of three groups was higher than that in the control group significantly. Moreover, Group A and C both exhibited an apparent increase in the SOD activity of the livers. In comparison with control group, the activities of T-AOC of the serum and livers of three groups remained unchanged remarkably through all the test periods; However, the activities of T-AOC had a little gone up. Only the Group B and C showed obviously increase in the activities of GSH-PX of the serum of Group B and C, nevertheless, the activities of GSH-PX of the livers of three groups had no significant differences. Furthermore, the contents of MDA in serum of Amur sturgeon were lower than that in the control group, and there were significantly different in the serum and livers of three groups. Our results evidently the selected prescriptions have the function to promote antioxidant defenses of Amur sturgeon in the different levels.
