It was determined by the total collection of excreta method, with broilers from 22 to 32 days of age, the coefficients of apparent metabolism of dry matter, crude protein and crude energy and apparent metabolizable energy corrected for zero nitrogen balance (AMEn) of the ethanol co-products of corn: acid oil and dried distillery grains with soluble (DDGS). The DDGS and corn acid oil presented nutritional metabolization coefficients ranging from 43 to 83% and AMEn equal 2393.5 and 7859.2kcal/kg respectively, and may be food alternatives to soybean meal and soybean oil.(AU)
