| The objective was to evaluate the effect of the ratio of degradable intake protein (DIP) to non-structural carbohydrate (NSC) on the nitrogen flows to duodenum of steers by replacement alfalfa silage with corn silage. Six Holstein steers fitted with ruminal and duodenal cannulae were divided into two 3 x 3 Latin squares with 20d periods. In the first Latin squareï¼ the steers were fed three diets contained (dry matter basis): 1) 100% alfalfa silage (AS100)ï¼ 2) 80% alfalfa silageï¼ 20% corn silage (AS80)ï¼ or 3) 60% alfalfa silageï¼ 40% corn silage (AS60). In the another Latin squareï¼ the steers were fed three diets contained (dry matter basis): 1) 40% alfalfa silageï¼ 60% corn silage (AS40)ï¼ 2) 20% alfalfa silageï¼ 80% corn silage (AS20) or 100% corn... |

| 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... |
