摘      要：[Objectives]The effect and mechanism of grape seed and sweet wormwood extract on growth of Monopterus albus were studied.[Methods]1 500 healthy *** with average mass of 23.8 g/tail were randomly divided into 5 *** control group was fed with basal diet and the experimental groups were fed with 10,20,30 and 40 g/kg of grape seed and sweet wormwood extract,*** growth performance of the fish was measured after 60 d of feeding at 23-28℃.[Results]The addition of grape seed and sweet wormwood extract in basal diet could increase the body weight gain rate,specific growth rate and protein efficiency,and decrease the feed *** activity of digestive enzymes,glutamic-oxaloacetic transaminase,glutamic-pyruvic transaminase,blood alkaline phosphatase and serum total protein was increased,and the contents of blood glucose and triglyceride were *** with the control group,the above indexes showed significant difference(P0.05)when the dosage was 10 and 40 g/kg(P0.05).[Conclusions]As a feed additive,the plant extract from grape seed and sweet wormwood could increase digestive enzyme activity and regulate blood biochemical parameters of fish *** had the function of promoting the digestion and absorption,enhancing the metabolic activity of 3 main nutrients,and hastening the growth of fish.
