鱼类早期营养程序化对后期生长与代谢影响的研究进展

Research Progress on Effects of Early Life Nutritional Programming on Growth and Metabolism of Later Life in Fish

动物生命早期来自内源(亲本)和外源(饲料)的营养,可引发对机体或各器官功能产生长期以至终身的影响,即营养程序化。在鱼类中,亲本性腺发育阶段和鱼苗生命早期是营养程序化的关键窗口期。从养殖的经济性、环保性和成鱼的品质角度考虑,将植物原料、碳水化合物、多不饱和脂肪酸等的营养程序化应用于鱼类的培育,将为提高鱼类生产性能提供有力支撑。本文简述了近期营养程序化对鱼类生长与代谢影响的研究概况,以期为鱼类营养调控研究与应用提供理论线索。

Early animal life, nutrition from endogenous (parent) and exogenous (feed) can trigger long-term or even lifelong effects on the body or organ function, named nutritional programming. In fish, the stage of parental gonad development and early life of larval are critical window periods for nutritional programming. From the perspective of economy, environmental protection and quality of marketable fish, the application of plant materials, carbohydrates and polyunsaturated fatty acids in the nutritional programming of fish culture will provide strong support for improving fish production. In this paper, the effects of nutritional programming on the growth and metabolism of fish were reviewed, in order to provide theoretical clues for the research and application of fish nutritional regulation.
