The aim of this work was to investigate the performance response of broilers fed diets with different Energy Density and Ideal Protein Profile levels. The experiment was carried out with a total of 240 1-day-old male broiler chickens randomly allocated in a completely randomized block design with 3 replicates with a 3 x 3 factorial arrangement. Experimental diets included the combination of 4 Energy Densities (3000, 3100, 3200 and 3300 Kcal ME/kg) and 4 Ideal Protein Profile Levels (90, 100, 110 and 120%). Birds were fed according to NRC (1994) requirements, adjusting the starter level of lysine from 1.10 to 1.21%. Energy Density levels of 3000, 3100 and 3300 Kcal ME/kg were obtained from the level of Energy Density of 3200 Kcal ME/kg recommended by NRC (1994) for both Starter and Grower diets. The amino acid levels corresponding to each Energy Density were considered 100% for the calculation of the Ideal Protein Profile Levels of 90, 100, 110 and 120%, so that the Ideal Protein Profile Level was constant. Maximum response for Body Weight, the most efficient feed conversion and maximum margin over feed, at the end of the growing period, was reached with the Energy Density level of 3200 Kcal ME / kg and Ideal Protein Profile Level of 110%.
