家禽净能的测定方法、影响其测定的因素及研究现状
Net Energy Determination for Poultry: Methods, Influential Factors and Current Research Situation
摘要
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 uti-lization of nutrients into maintenance and production requirements. It is the only system by which energy re-quirements 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.关键词
