摘      要：Two control diets based on the commercial formula were designed to contain high(27%,D1)and low(22%,D2)levels of fish meal,*** D2,500,1000 and 1500 mg kg 1 of yeast extract were added,respectively,yielding three experimental diets(YE1 through YE3).Shrimp(initial body weight 0.30 g±0.02 g)were fed with the experimental diets,five tanks each diet and 30 shrimp individuals each tank,for 8 weeks,and then challenged with Vibrio *** results showed that the specific growth rate(SGR)of shrimp in D2 was significantly lower than that of shrimp in D1(P0.05).YE significantly improved the activity of glutathione *** concentration of glutathione(GSH)and the total serum anti-oxidative capacity(T-AOC)of D1 were significantly higher than those of shrimp feeding other diets(P0.05).In conclusion,1000 1500 mg kg 1 of YE was suggested to be supplemented into the practical diets to improve the growth,anti-oxidative capacity and intestinal mor-phology of shrimp ***.
