The objective of this work was to evaluate the chemical characteristics of Miyagi grass silage (Megathyrsus maximus cv. Miyagi), with the addition of moisture sequestrants (ground corn grain - GCG, and dried distillers grain with solubles and high fiber, DDGS), and addition of inoculant (SiloSolveMC) and/or acid (Mold-Nil Liquid). The experimental design was completely randomized in a 3x3 factorial arrangement, with five replications: factor 01, the use of moisture scavengers (without additive, with the addition of GCG and/or DDGS), and factor 2, the use of bacterial inoculant (SiloSolveMC) and/or acid (Mold-Nil Liquid). For the chemical evaluation of the silage, the percentage of dry matter (DM), the insoluble fiber in neutral detergent (NDF), mineral matter contents (MM), and crude protein (CP). There were no interactions between moisture scavengers, bacterial inoculants, and/or acids. The use of moisture scavengers interfered with DM (P<0.05), observing a value with GCG and DDGS use of 36.18% and 35.46%, respectively, higher than MGS (27,68%). For NDF values using GCG and DDGS, values of 51.39% and 65.47%, respectively, lower (P<0.05) than MGS (70.72%) were observed. The use of microbial inoculant and acid did not alter (P>0.05) the OM values, with an average value of 92%. As for CP, there was no interaction (P>0.05) of moisture scavengers, microbial inoculant, and/or acid. It is recommended to include moisture-sequestering foods associated with MGS to obtain better DM, NDF, and CP values after opening the bag and the use of microbial inoculants and/or acids in the MGS did not influence these characteristics.
