Implementation of a Net Energy System for Meat Chicken Feed Formulation

During this study a series of diets were formulated using NE and AME and some diets were fed to broilers in a closed-circuit indirect calorimetric chamber to determine energy values. The findings showed that both AME and NE can be used to formulate broiler diets. Using NE versus AME to formulate broiler diet will impact the procurement strategy for raw materials. Protein ideally balanced with NE dictates the performance, live weight and FCR, and not AME content of the diet. The supremacy of the NE system is greater in lower energy diets and when formulating diets during the early age of the broilers. NE is a better performance predictor than AME.
