The aim of this study was to evaluate the chemical composition, energy values and nutrient metabolizability coefficients of corn grown using different organic fertilizers and its use for feeding slow-growing broilers. Two experiments were conducted. In the first experiment, two hundred 21-day-old broilers were distributed in a completely randomized design, with five treatments and four replicates of 10 birds per experimental unit. The treatments were a control diet and four test diets (corn fertilized with crotalaria, corn fertilized with millet, corn fertilized with humus, and corn without fertilization), including corn at 30% in the control diet. The apparent metabolizable energy, apparent metabolizable energy corrected for nitrogen balance, and apparent metabolizability coefficients of dry matter, crude protein and gross energy were determined. In the performance trial, two hundred and fifty 1-day-old chicks were distributed in a completely randomized design into five treatments (T1 control diet with commercial corn, T2 corn without fertilization, T3 corn fertilized with humus, T4 corn fertilized with millet and T5 corn fertilized with crotalaria) and five replicates of 10 birds per experimental unit. Weight gain, feed intake, feed conversion and final weight at 20 days were evaluated. The AME and AMEn values of corn fertilized with crotalaria, millet, humus and corn...
