Abstract：The experiment aimed to investigate the effects of chestnut tannin on the growth performance,serum biochemical indicators,hepatic antioxidant capacity,and muscle amino acid composition of the Pelodiscus sinensis.A total of 1 050 Pelodiscus sinensis with an initial body weight of(12.54±0.54)g were randomly divided into five groups,with three replicates per group and 70 turtles per replicate.The Pelodiscus sinensis in groups were fed diets containing 0％(control group),0.05％,0.10％,0.20％,and 0.40％chestnut tannin.The experiment lasted for 60 days.The results showed that on the 30th day,the feed conversion rate(FER)and protein efficiency rate(PER)of group 0.10％were significantly higher than those of control group(P＜0.05).On the 60th day,the final weight(FBW),weight gain rate(WGR)and specific growth rate(SGR)of experimental groups were significantly higher than those of control group(P＜0.05).Compared with the control group,the activities of serum total superoxide dismutase(T-SOD)and catalase(CAT)in 0.20％and 0.40％groups were significantly decreased(P＜0.05),and serum glutathione peroxidase(GSH-Px)in 0.05％,0.10％and 0.40％groups were significantly decreased(P＜0.05);Serum alkaline phosphatase(ALP)activity in 0.40％group was significantly increased(P＜0.05),serum high density lipoprotein(HDL)content in 0.40％group was significantly increased(P＜0.05),and serum total bilirubin(TBIL)content in 0.05％and 0.20％groups was significantly decreased(P＜0.05).Compared with the control group,the contents of muscle serine,leucine and proline in 0.20％group were significantly decreased(P＜0.05).The mRNA expressions of SOD1,SOD2,CAT,GPx3 and GPx4 in 0.20％group were significantly increased(P＜0.05).The study indicates that adding 0.20％and 0.40％chestnut monrather in the diet can improve the growth performance,promote the synthesis of sugar and lipid,and enhance the antioxidant performance of liver,but does not affect the muscle flavor and nutrition.
