鱼类糖营养生理的研究进展

摘要

Protein ,lipid and carbohydrate are the three major nutrients in fish feed .Carbohydrate ,as one of the important energy sources ,not only inexpensive ,also has the protein-sparing effect .The appropriate supplementation of dietary carbohydrate can improve grow th performance and feed effi‐ciency of fish .However ,a prolonged postprandial hyperglycemia and persistent metabolic stress were generally observed after feeding carbohydrate-rich diets .For nearly 30 years ,especially in recent 10 years ,the carbohydrate nutrition physiology of fish was studied extensively ,a certain achievements were obtained in fish’s capacity of carbohydrate utilization and its influence factors as well as the opti‐mal dietary carbohydrate levels . T his paper review s the research achievements and methods of this field ,by reviewing and summarizing related researches both in domestic and abroad ,to provide litera‐ture data for the carbohydrate nutritional physiology research of fish .%蛋白质、脂肪和糖类是鱼类饲料中的三大营养物质，糖类作为重要的能量物质，不仅价格低廉，还具有节约蛋白质、保护环境等作用。饲料中添加适量的糖类可以促进鱼类生长、提高饲料效率。而糖类的过量添加会导致鱼类血糖升高，甚至产生一系列的病理反应，影响其生长和健康。因此，糖类物质在饲料中的正确使用十分重要。近30年来，人们对鱼类糖营养生理领域进行了广泛的研究，特别是近10年来在鱼类对糖的利用能力和特点、影响因素和最适添加水平等方面取得了一系列成果。本文通过对国内外相关研究的回顾和总结，对这一领域的研究成果和研究方法进展进行综述，以期为鱼类的糖营养生理研究提供文献数据。
