The objective of the study was to measure the beneficial effects of lactic acid bacteria (LAB) inoculation on the nutritive value of oat silage collected from thirteen regions in the Republic of Korea. The contents of crude protein, acid detergent fiber (ADF), neutral detergent fiber (NDF) and crude ash (CA) were slightly lower in LAB inoculated silage when compared with the control silage, whereas inoculation of LAB resulted in increased total digestible nutrient (TDN). Higher number of LAB, but lower count of yeast and fungi indicated the effectiveness of the LAB inoculation on oat silage fermentation. LAB inoculation resulted in low pH silage, which may prevent undesirable microbial growth. The LAB inoculation promoted lactic acid dominant fermentation with marginal levels of acetic acid and butyric acid in oat silage. These data suggest that the LAB inoculation may preserve oat silage at better quality for ruminant animal production.
