Effects of Dietary Bacillus amyloliquefaciens on Growth Performance and Hepatic Function in Juvenile Black Seabream (Sparus macrocephalus)
摘要
Abstract
In order to investigate the effect of bacterium Bacillus amyloliquefacieus on growth performance,digestive enzymes activities,serum proteins levels and liver superoxide dismutase (SOD) activity in juvenile black seabream (Sparus macrocephalus),this paper reared the fish with 7 g body weight in a small cement pool of an indoor microwater circulation system and fed diets containing Bacillus amyloliquefacieus at a dose of 0,0.025%,0.05%,and 0.1%,respectively.After 56 d,the results showed that the bacterium led to improve weight gain rate (WGR) and specific growth rate (SGR) in juvenile black seabream.The WGR and SGR were significantly higher in juvenile black seabream fed by diet supplemented with 0.05% of Bacillus amyloliquefaciens than that of the fish fed by control diet.The intestinal protease and lipase activities in the fish fed by diet supplemented with Bacillus amyloliquefaciens were significantly higher than that of the control group.The total serum protein levels of juveniles fed with 0.025% Bacillus dietary supplement were significantly higher than that of the control group,among them the globulin and albumin levels were extremely increased.In addition,the intestinal amylase activity and hepatic SOD activity were also obviously higher in the 0.1% Bacillus amyloliquefaciens dietary supplement group than that of the control.These results indicated that optimal dose of Bacillus amyloliquefaciens administration could increase the intestinal digestive enzyme activity,improve antioxidant ability in juvenile black seabream,and promote their growth performance.关键词
