Metabolizable energy (ME) of corn with different geometric diameters was determined in European quail with 26 days of age with 124 g of mean live weight, using the Total Collection of Excreta Method. One hundred and twenty five quails were divided in five treatments, five replications with five quails each, with one treatment used to determine endogenous losses. Values of Average Geometric Diameter (AGD) of the corn were 600, 800, 1000 and 1200 µm. ME of corn was not affected by AGD. Average values were 3079, 3274, 3300, 3137 Kcal/kg respectively for apparent metabolizable energy, corrected apparent metabolizable energy, true metabolizable energy, corrected true metabolizable energy.
