Abstract: 【Objective】 This study was conducted to evaluate the effects of hydrolysable and condensed tannins on growth performance,body composition,digestive enzyme activities,serum biochemistry and antioxidant indexes of Litopenaeus vannamei.【Method】 A total of 800 shrimp (initial body weight was 1.04 g±0.02 g) were randomly divided into 5 groups with 4 replicates per group and 40 shrimp per replicate.Five diets including CON (control),HT0.1 (adding 0.1% hydrolysable tannins),HT0.2 (adding 0.2% hydrolysable tannins),CT0.1 (adding 0.1% condensed tannins) and CT0.2 (adding 0.2% condensed tannins) were formulated.The experiment lasted for 56 d.At the end of the experiment,the weight,quantity,and feed intake of shrimp per tank were counted to calculate the growth performance.Shrimp were randomly selected from each tank to determine the body compositions.Blood was collected from the cardiocoelom of shrimp to separate serum for determination of serum biochemical and antioxidant indexes.Hepatopancreas of shrimp were separated to determine the antioxidant indicators.Intestine of shrimp was separated for determination of the intestinal digestive enzyme activity.【Result】 Compared with CON,the final body weight (FBW),feed intake (FI),weight gain rate (WGR) and specific growth rate (SGR) in HT0.1 were significantly increased (P<0.05),the FI in CT0.1 was significantly decreased (P<0.05),and the FBW,FI,WGR and SGR in CT0.2 were significantly decreased (P<0.05).The intestinal trypsin and lipase activities of shrimp in CT0.1 and CT0.2 were significantly decreased (P<0.05).Compared with CON,HT0.2,CT0.1 and CT0.2 had higher (P<0.05) serum alanine transaminase and aspartate aminotransferase activities,HT0.1 and HT0.2 had higher (P<0.05) total antioxidant capacity (T-AOC),HT0.1 had higher (P<0.05) but CT0.2 had lower (P<0.05) serum catalase (CAT) activities,the serum malondialdehyde (MDA) level of shrimp in HT0.1,HT0.2,CT0.1 and CT0.2 were decreased (P<0.05).Compared with CON,the hepatic T-AOC of shrimp in CT0.1 was increased (P<0.05),the hepatic superoxide dismutase activity of shrimp in HT0.1,HT0.2,CT0.1 and CT0.2 were increased (P<0.05),the hepatic CAT activity of shrimp in HT0.1 and CT0.1 were increased (P<0.05),and the hepatic MDA level of shrimp in HT0.2 was decreased (P<0.05).【Conclusion】 Taking the growth,digestion and antioxidation of Litopenaeus vannamei as the comprehensive evaluation indexes,the effects of supplementation of hydrolysable tannins was better than that of condensed tannins,and the appropriate ratio of dietary hydrolysable tannins was 0.1%.
