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
