Abstract
In this study,Xenocypris davidi was taken as the subject.By adding different levels of taurine into feed,the effects of taurine on the activities of various enzymes in liver and muscle of Xenocypris davidi were studied.A total of 300 Xenocypris davidi with an initial body weight of about 10 g were randomly divided into 5 groups with 3 parallels and 20 tails in each group.The culture cycle of the experiment was 8 weeks.The results showed that taurine supple-mentation had significant effects on various enzyme activities of Xenocypris davidi(P<0.05).In liver and muscle,CAT(catalase),MDA(malondialdehyde),T-SOD(total superoxide dismutase),AKP(alkaline phosphatase),ACP(acid phosphatase)and other enzyme activities were regulated to varying degrees,among which CAT activity reached the highest value in D3 group,MDA activity reached the lowest value in D3 group.T-SOD activity increased with the increase of taurine supplementation,and then decreased after reaching the peak value in D4 group.AKP and ACP activities showed different trends in different treatment groups,but were significantly higher than those in control group.The comprehensive analysis showed that taurine could regulate the activity of various enzymes in Xenocypris davidi,which was of great significance for maintaining physiological function and antioxidant capacity of organism.关键词
