This study was conducted to evaluate the effect of Zingiber officinale extract (ZE) on digestive enzyme activity (chymotrypsin, trypsin, protease, amylase, and lipase) and some biochemical parameters (alkaline phosphatase (ALP), total protein (TP), albumin (ALB), globulin (GLU) and lysozyme) of Litopenaeus vannamei shrimp. A total of 600 post larvae shrimps (initial weight, 1.06±0.7 g) were randomly distributed into 12 fiberglass tanks representing four treatments at a rate of 50 shrimp in each tank. The control shrimp group (ZE0) was fed a ZE free basal diet. Other groups were fed the basal diet supplemented with 0.5 (ZE 0.5), 1.0 (ZE1) and 1.5 (ZE 1.5) g kg-1 diet. Results revealed that activity of protease, amylase, and lipase and value of TP, ALB and GLU of the shrimp have significantly increased (p<0.05) in the ZE0.5 and ZE1groups compared with the ZE1.5 group and control group. The highest amylase (1.35± 0.5 U mg -1protein) and lipase (0.09±0 U mg-1protein) activity was observed in the ZE1 group. It can be concluded that use of Z. officinale ZE0.5 and ZE1 kg-1diets could suggest for increasing digestive enzyme activity and some biochemical parameters of L. vannamei.
