The AMEn system was developed and then perfected based on this basis and assumption; that broilers will be fed on corn and soybean meal-based diets.

This is a question that was debated hotly during the last meeting of the American Poultry Science Association. Here, the question is not whether the net energy (NE) feed formulation system is superior to the one currently used, namely the AMEn, which stands for apparent metabolizable energy at zero-nitrogen balance. The theory behind the NE energy system is by default superior to that of the AMEn or any other expression of metabolizable energy. Simply, the NE system takes into account more losses of energy as the animal converts feed energy to body energy. As such, it is more accurate.
