左旋肉碱作为水产饲料添加剂的应用前景

The Prospect of L -Carnitine as a Additive in Fish Diets.

L-肉碱又称肉毒碱，其对于动物的营养代谢具有非常重要的作用。在水产动物饲料中添加适量的L-肉碱，有着提高水产动物生长速度，降低饲料系数；提高水产动物蛋白含量，降低体脂率，改善肉质，提高鱼类的繁殖率等功能，是一种新型的功能性营养添加剂。本文在大量相关研究文献的基础上，概述了L-肉碱的来源、水产动物对其吸收和代谢的机制、生物学功能以及在水产动物体内的营养生理学效应，并针对目前L-肉碱的使用存在的问题，提出了一些建议，展望了其广阔的应用前景。

L - Camitine is known as a vitamin - like nutrient, which processes β - oxidation. It is a new bioactive additive. It was applied in aquatic animals and got widely attention. The thesis reviewed the research progress on L - carnitine; summarized its nutrition effects on aquatic animal ;emphasized the significance of its application as a additive in fish diets, then put forward of its prospect.
