This study was carried out to improve the quality and nutritive value of corn stover, moisture content of corn stover was 30 %. Seven different corn stover silages added with rice bran (0, 5, 10, 15, 25, 30 %) and 2 % urea (DM basis) were made and moisture content of corn stover silage was 65 %. After 40 days, corn stover silage added with rice bran were analyzed chemical composition, in vitro dry matter digestibility (IVDMD) and volatile fatty acids (VFA). Crude protein, crude fat and IVDMD of corn stover silages added with rice bran and urea were higher than those of corn stover silage (control). Lactic acids of corn stover silage added with rice bran and urea were increased to the control silage (r=0.95* ). The optimum level of rice bran was above 25 %
