摘　　要：研究动物的基础氮代谢是测定蛋白质真消化率的关键步骤,是了解动物维持蛋白质需要的必要环节,准确测定动物的内源氮损失具有重要意义。本文对基础氮代谢、无氮日粮法及存在问题和影响无氮日粮配制的因素进行了综述。Study of animal basal nitrogen metabolism is a key step in determining the real digestibility of protein.It is important to study the maintain protein needs of animals and to accurately determine the loss of endogenous nitrogen in animals.In this paper,the basic nitrogen metabolism,nitrogen-free diets and the affected factors of the nitrogen-free diets compound were reviewed.

关 键 词：基础氮代谢 无氮日粮 维持蛋白质需要
