The objectives of this study were to evaluate the chemical composition and energetic values of diferent high moisture corn grain silages (HMCGS) for swine, and to adjust prediction equations for digestible (DE) and metabolizable (ME) energy based on the chemical composition. The treatments consisted of eight diferent high moisture corn grain silages that substitued 30.0% of the basal diet. The analysis of DM, CP, EE, ADF, NDF, Ca and P were performed for the refered silages. To determine the energetic values 36 swines were used, alloted in a randomized blocks design with four replicates. The values of DE and ME of the HMCGS varied from 3494 to 3701 kcal/kg of DM and from 3392 to 3613 kcal/kg of DM, respectively. The equations adjusted to predict the DE and ME values of the HMCGS did not show a good adjustment, showing low determination coefficients, and the fat content showed a positive relation and the CF a negative one, for the energetic values studied.
