Abstract: 【Objective】 This study was conducted to evaluate the feeding effect of different plant tannin preparations on Litopenaeus vannamei.【Method】 A total of 600 shrimp were randomly selected and divided into 5 groups with 3 replicates per group and 40 shrimp per replicates.Five isonitrogen and isolipid diets were prepared containing 0 (G1), 0.1% (G2) and 0.2% (G3) Chinese gallotannin preparations, and 0.1% (G4) and 0.2% (G5) chestnut tannin preparations.The experiment was lasted for 42 days.At the end of the experiment, the weight, quantity, and feed intake of shrimp each tank were counted to calculate their growth performance.Blood was collected from the cardiocoelom of the sampled shrimp to separate serum for determination of serum biochemical and serum antioxidant and immune indicators, and the intestine of the shrimp was separated for determination of intestinal digestive enzyme activity.【Result】 Compared with G1, the feed coefficient of shrimp in G5 was significantly increased (P<0.05), while the intestinesomatic index and meat rate were significantly decreased (P<0.05).The content of serum triglyceride of shrimp in G3 was significantly decreased (P<0.05), and the contents of serum glucose, triglyceride and urea nitrogen of shrimp in G5 were significantly decreased (P<0.05).Compared with G1, the content of serum malondialdehyde in G3 was significantly decreased (P<0.05), while the content of serum immunoglobulin M in G5 was significantly increased (P<0.05).Compared with G1, intestinal trypsin activity of shrimp in G2 and G3 were significantly increased (P<0.05).【Conclusion】 Taking growth performance, antioxidant capacity and intestinal digestive enzyme activity as comprehensive evaluation indicators, 0.2% Chinese gallotannin preparation had a good application effect on Litopenaeus vannamei.
