The objective of this study was to determine the digestibility coefficient (DC) of nutrients and the digestible energy (DE), and metabolizable energy (ME) values of distillers dried grains with solubles (DDGS) produced in Brazil by different methods. Eight barrows with 23.3±4.1 kg were housed in metabolic cages in a randomized block design and fed diets containing 0, 200, 400, and 600 g kg–1 of corn DDGS. We determined the digestibility of dry matter (DM), organic matter (OM), crude protein (CP), ether extract (EE), mineral matter (MM), neutral detergent fiber (NDF), and gross energy (GE) by the total collection (TC) and chromium oxide marker (Cr) methods. Distillers dried grains with solubles provided the respective DM, OM, CP, EE, MM, NDF, and GE values of 910, 863, 286, 66.9, 46.8, 500 g kg–1, and 4,780 kcal kg–1. The DE and ME values of DDGS were 3,739 and 3,401 kcal kg–1 and 3,691 and 3,213 kcal kg–1 as determined by TC and Cr methods, respectively. The growing inclusion of DDGS did not affect the DE or ME values. The digestibility coefficients of DM, OM, CP, EE, MM, and NDF were 767, 765, 827, 691, 883, and 821 g kg–1, respectively, by the total collection method. The Cr underestimated the values of all variables compared with TC method. Levels up to 600 g kg–1 of the test ingredient do not influence the DE and ME of DDGS, but compromises the digestibility coefficients of DM, OM, and NDF.
