To clarify the influence of feeding of the silage using leftover vegetables on the milk production and nutritional status, seven multiparous and three primiparous dairy cows were assigned to one of two diets which contained 15% leftover vegetables silage in dry matter (group T) or 12% corn and sorghum mixed silage in dry matter (group C) . The following results were obtained: (1) There was no significantly difference in body weight, dry matter intake, nutrient (ME, TDN and CP) sufficiency to Japanese Feeding Standard between the two groups, (2) Judging from the rumen fluid character, there was no abnormal condition in ruminal fermentation. Only molar percent of butyric acid to total volatile fatty acids were significantly lower after feeding for group T than group C, however there was no significantly difference at pre-feeding. (3) In the blood metabolism, there were nothing nutritional disorder, though albmin and blood urea nitrogen were significantly lower both pre and after feeding for group T than group C. These results indicated that the milk production and nutritional status were not affected by feeding of the leftover vegetables silage in total mixed rations feeding system and dietary ingredients of this feeding trial.
