Experiments were to compare fermentative quality and intake by dairy heifers of combined (nonchopped but bound) fresh rice straw silage (combined silage) with those of chopped fresh rice straw silage (chopped silage), which were prepared with or without molasses (M) or a mixture of molasses and lactic acid bacteria (M + L) as additives. Fermentative rate of chopped silage was higher than that of combined silage and intake of DM of the combined silage by heifers was 2.4 times that of chopped silage. Silage quality was greatly improved by M + L, giving no butyric acid, little ammonia N and much lactic acid. Scores representing the quality of silage based on composition of organic acids were 0 for control, 16 to 49 for M, and 100 for M + L. There was little difference in intake by heifers between combined silage with or without additive.
