摘要:

本研究以高价值经济鱼种马口鱼为研究对象,针对其人工养殖中因饲料营养不合理引发的内脏脂肪沉积、肝肠健康受损等问题,设置对照组(商业化饲料)、胆汁酸添加组、胆汁酸与牛磺酸复合添加组开展56 d养殖试验,通过代谢组学技术分析马口鱼肝脏代谢物。结果表明,胆汁酸添加组、胆汁酸与牛磺酸复合添加组均能改变马口鱼肝脏的代谢谱,差异代谢物主要富集于花生四烯酸代谢、初级胆汁酸合成、胆汁分泌等脂肪代谢与消化系统相关通路。其中,单独添加胆汁酸抑制马口鱼肝脏中胆固醇转化合成胆汁酸与结合型胆汁酸。在饲喂胆汁酸基础上添加牛磺酸会促进马口鱼肝脏中游离初级胆汁酸与结合型胆汁酸的合成。以上结果可为马口鱼高效复合胆汁酸饲料添加剂配方开发提供理论基础,解决其人工养殖的饲料营养不适配的问题。

Abstract:

This study focused on the high-value economic fish species Opsariichthys bidens as the research object. In response to the problems of visceral fat deposition and liver and intestinal health damage caused by unreasonable feed nutrition in its artificial breeding,a control group(commercial feed),a bile acid addition group,and a bile acid and taurine composite addition group were set up for a 56-day breeding experiment. Metabolomics technology was used to analyze the liver metabolites of Opsariichthys bidens. The results showed that both the bile acid addition group and the bile acid-taurine composite addition group could alter the metabolic profile of Opsariichthys bidens liver. Differential metabolites were mainly enriched in pathways related to fat metabolism and digestive system,such as arachidonic acid metabolism,primary bile acid synthesis,and bile secretion. Among them,the addition of bile acid alone inhibited the conversion of cholesterol into bile acid and conjugated bile acid in the liver of Opsariichthys bidens. Adding bile acid-taurine composite can promote the synthesis of free primary bile acids and conjugated bile acids in the liver of Opsariichthys bidens. The above results can provide a theoretical basis for the development of an efficient composite bile acid feed additive formula for Opsariichthys bidens,and solve the problem of nutritional incompatibility in its artificial breeding feed.
