| The objective was to evaluate the effect of different proportion of alfalfa silage and corn silage on the nitrogen utilization and milk production of dairy cows. Eighteen lactating Holstein cows were divided into three treatment groups. The cows in the three treatment groups were fed mixture of alfalfa silage and corn silage，which were formulated (dry matter basis) at 1) 80:20 (AS80)，2) 60:40 (AS60) and 3) 40:60 (AS40) ratios，respectively. Grass hay and concentrate were fed also to adjust silage ratio (65% of total DM)，roughage ratio (70% of total DM) and CP contents (15%DM) of the diets among AS80，AS60 and AS40. The ratio of degradable intake protein (DIP) to non-fibrous carbohydrate (NFC) in AS80，AS60 and AS40 were 0.27，0.27 and 0.28，respectively. Milk... |
