胆汁酸是胆固醇衍生的一类固醇酸,各种胆汁酸以一定的比例存在于不同动物胆汁中,在动物脂肪代谢过程中起着重要作用。作为一种新型的饲料添加剂,生产实践中已验证了胆汁酸的功效,胆汁酸的使用范围也越来越广泛。为使胆汁酸的作用与功能为更多的人所认识了解,并合理地选择和使用胆汁酸产品,本文首先介绍了胆汁酸的生理作用机制,随后综述了近年来胆汁酸在水产动物中的营养研究进展。多年的研究结果表明,适宜的胆汁酸产品能够有效地促进水产动物的生长,并在改善养殖鱼类品质方面有显著的效果。 Bile acids are a kind of sterol acids derived from cholesterol. Various bile acids exist in bile of different animals in a certain proportion and play an important role in animal fat metabolism. As a new type of feed additive, the efficacy of bile acids has been verified in production practice. The use of bile acids is also becoming more and more widespread. In order to understand the function and function of bile acids for more people and to select and use bile acid products reasonably, this paper first introduced the physiological mechanism of bile acids, and then reviewed the recent progress of bile acids in aquatic animals Advances in Nutrition Research. Years of research have shown that suitable bile acid products can effectively promote the growth of aquatic animals and have a significant effect in improving the quality of farmed fish.
