Eight hundred and sixty four broiler chicks were used, with average weight of 160 ± 5g, randomly distributed in 48 boxes (experimental unit), experimental unit in a factorial 4x4 with four levels of ME (2,700, 2,825, 2,950, and 3,075 kcal kg-1) and four levels of DL (1,080; 1,187; 1,295 and 1,403%) resulting in 16 treatments with three replications.
Increases in levels of ME and DL in the diets caused significant interaction (P 0.05) in weight gain and feed conversion.
