A.  aRehydration of dry corn grain as an alternative for conservation purposes.h[electronic resource]  c2018  aGlycerol, the main constituent of crude glycerin, has high energy efficiency and may provide energy to microorganisms in silage. Therefore, we evaluated the effect of including crude glycerin (CG) and a bacterial inoculant on the chemical composition, losses, fermentation profile, microbial population and aerobic stability of rehydrated corn grain silage. The dry corn grain (800 g kg-1 dry matter (DM)) was milled to 5 mm and rehydrated with water and glycerin to achieve 32.5% moisture content. Crude glycerin was added at 0, 75, 150 and 225 g kg-1 (natural matter (NM)), with or without bacterial inoculant. The experiment was randomized, and included three replicates in a factorial scheme, with or without bacterial inoculant, four crude glycerin levels and five fermentation periods. CG inclusion in silage decreased the nitrogenous and fibrous fractions, gas losses, DM recovery, and microbial growth. However, CG addition increased effluent and total DM losses. Treatment with 0 and 75 g kg-1 CG (NM) resulted in lower pH (4.6; 4.28) at 64 days of fermentation. Silage without CG remained stable to oxygen after 12 days. The bacterial inoculant did not influence the variables analyzed. We conclude that CG inclusion, bacterial inoculant or a combination of these additives is not recommended for this type of material. Nevertheless, rehydration with water (125 g kg-1 DM) is an alternative for storage of corn grain silage through the ensiling process.  aBiofuels  aGlycerol  aLactobacillus  aSilage1 aPEREIRA, D.
