ABSTRACT
Due of the high cost that the feeding represents on poultry production, the knowledge about chemical and energy food composition is required to get accurate ration formulas, aiming a better performance and high economy. So, the aim of this work was determine the chemical composition, energetic values and the values of metabolizability coefficients of different corn cultivar for poultries. The total excreta collecting method was used to determine the energetic values, with nine different corn cultivars, one reference ration, four replicates and five birds per experimental unit. The values for apparent metabolizable energy (AME) and AME nitrogen corrected (AMEn), variety from 3113 to 3550 kcal/kg MN and from 3069 to 3473 kcal/kg MN, respectively. Differences (P
