摘要: 能量是肉鸡各种生命活动的基础,也是肉鸡饲料中价格占比最高的元素,主要源于日粮中碳水化合物、脂肪和蛋白质的化学能。准确评估肉鸡能量需要量和日粮成分能量水平在肉鸡营养和生产中具有重要的科研和经济价值。代谢能(ME)体系是目前用于家禽饲料原料能值评定的成熟体系,在家禽营养和配方中被广泛使用。但和净能(NE)体系相比,代谢能体系忽略了饲料中不同原料成分摄食和消化过程中的热增耗(HI)差异对原料能值评价的影响,降低了原料能值评定的准确性。因此,作者结合国内外肉鸡净能相关研究进展,重点就肉鸡净能测定方法、肉鸡原料净能预测方程和影响肉鸡净能体系应用因素等方面进行综述讨论,以期为净能体系在肉鸡生产中的应用提供参考。

Abstract: Energy is the basis of all life activities for broilers,and it is also the most expensive part of broiler diets.Grains,protein meals and edible oils consumed by broilers yield energy when oxidised during metabolism.Accuracy energy requirement continues to gain economic importance and research importance as a component of broiler feed.Almost all poultry feed is currently formulated on the basis of metabolisable energy (ME).Formulation of broiler feed on a net energy (NE) basis may be more accurate than the ME system as it takes into account the energy lost as heat increment (HI).Therefore,combined with the related research progress of net energy of broilers at home and abroad,this paper focuses on the methods of measuring net energy of broilers,the prediction equation of net energy of raw materials and the factors affecting the application of net energy system of broilers,in order to provide reference for the application of net energy system in broiler production.

Key words: broiler; net energy; determination methods
