Net energy in poultry: Its merits and limits

Development of a net energy (NE) system in poultry has been a topic of research for many decades, following its successful implementation in pigs. However, up to now, no such system for poultry is in use, as the added value of a NE system in poultry over the current AME system(s) has not yet been demonstrated. In this paper, the merits and limits of a NE system in poultry are discussed for fast-growing broilers.
