Effects of Different Bile Acids on Growth Performance,Serum Biochemical and Lipid Metabolical Indexes of Spotted Seabass(Lateolabrax maculatus)
This study investigates effects of different bile acids on growth performance,serum biochemical and lipid metabolism indexes of spotted seabass(Lateolabrax maculatus).A total of 240 fish((16.00±0.50)g)were randomly divided into 12 tanks.The fish were fed with basal diet,diets supplemented with carri-er bile acid,bile acid NE and liquid bile acid L,respectively.After 8 weeks of feeding,samples were collected and analyzed.The results showed that,compared with the control group,bile acid NE group significantly in-creased the weight gain rate(WGR),food intake(FI)and the serum lysozyme activities(P＜0.05);liquid bile L group significantly reduced the WGR and FI(P＜0.05),and no significant effect on serum immunity was observed(P＞0.05);however,carrier bile acid had no significant effect on WGR and serum immunity(P＞0.05).Compared with control group,other 3 bile acid supplementation groups significantly decreased the activ-ities of serum glutamic oxaloacetic transaminase,liver acetyl-CoA carboxylase(P＜0.05).Moreover,bile acid NE group significantly increased hepatic lipoprotein lipase activities(P＜0.05),and improved the liver tissue structure.In conclusion,bile acid NE could improve fat catabolism,reduce fat deposition to maintain liver health.Based on the comprehensive analysis of growth performance,serum biochemical and lipid metabolism indexes of spotted seabass,the bile acid NE might be suitable form for the supplement of bile acid.
