Abstract

Evaluation of energy value in poultry feeds has been most commonly based on metabolizable energy(ME) system. However, the closest estimate of the "true" energy value of a feed should be net energy(NE) system. NE system takes into account of the heat increment(HI), which is the amount of heat released from the energy costs in ingestive, digestive and metabolic processes. In addition, NE system divides the energy utilization of nutrients into maintenance and production requirements. It is the only system by which energy requirements and feed or diet energy values are expressed on a same basis. This article reviewed the methods of determination, influential factors and current research situation of NE in poultry.
