摘 要：
准确评定饲料能量的有效能值是以最佳效率满足家禽的营养需要以及保证其良好的生产性能的关键。净能体系在代谢能体系的基础上考虑了热增耗的损失,在能量分配上更加全面,作为评定体系逐渐被推广,能量饲料原料作为家禽重要的日粮能量来源,提高其能值评定的准确性不仅有利于饲料配方的设计,还能降低生产成本、提高利润。因此,文章综述了家禽净能体系的构建及优势,及其在能量饲料原料上的应用研究进展。

摘 要：
Accurate evaluation of the effective energy value of feed is the key to meet the nutritional requirement of poultry and industrial requirement for poultry production performance with the best efficiency. Net energy system is more comprehensive in energy partitioning since it has considered the loss of heat increment compared with metabolizable energy system. Thus, as an evaluation system, the net energy system has been gradually promoted. As energy feedstuff is an important source of dietary energy for poultry, improving the accuracy of its energy evaluation could not only improve the configuration of feed formulation, but also reduce the production costs and increase profits. Thus, this article summarized the construction and advantages of poultry net energy system and its application research advances on energy feedstuffs.
