This experiment was conducted to determine the effect of management practices on the quality of round baled grass silage at experimental field of grassland and Forage Crops division, National Livestock Research Institute, RDA, Suwon from 1997 to 1998. The experiment was consisted of three different wilting days : 0 (unwilted), 0.5 and 1 day with three replications. Crude fiber content was increased with prolonged wilting period, but other components did not show any trends. There was no significant differences in acid detergent fiber (ADF) and neutral detergent fiber (NDF) content between wilting periods, but there was significant difference in IVDMD (in vitro dry matter digestibility) between one-day wilted and unwilted silage. Dry matter (DM) content changed from 23.7% to 40.5% in relation to prolonged wilting period. Wilting treatment caused a decrease in each organic acid content of round baled grass silage and an increase in the silage quality. Wilting also could reduce the DM loss. This study demonstrated that one-day wilting would be a recommendable method for making high quality round baled grass silage.
