The chemical composition, the apparent metabolizable energy (AME) and apparent metabolizable energy corrected by nitrogen (AMEn) of six feed of vegetal origins were determined by the total excreta collection method. A total of 252 male broiler chicks of the lineage Ross with 21 days of age were distributed in a completely randomized experimental design, with seven treatments (one basal reference diet and six test diets), six replicates and six birds per experimental unit. The evaluated feeds were: corn (CO), high oil corn (HOC), whole corn germ meal (WCGM), toasted whole soybean (TWSB), soybean hulls (SH), high protein soybean meal (HPSM) with 50% crude protein. The evaluated feeds were included in the diets-test in 40% and 25% of the reference diet, for the energy and protein feeds, respectively. The values of AME, in kcal/kg of as fed, for the feeds CO, HOC, WCGM, TSB, SH and HPSM were 3.402, 3.627, 3.019, 3.419, 814 and 2.070 and the AMEn values were: 3.393, 3.595, 2.935, 3.279, 741, and 1.984, respectively.
