Popis:	Corn silages were treated at harvest with 0.5% urea or 1.3–2.2% ammonia-molasses-mineral solution. Apparent recoveries of added nitrogen in the corn silages ranged from 95 to 100% in both experiments. Water-insoluble N and lactic acid contents were increased in the treated silages as compared to the control. Four diets containing either (1) grass-legume (GL) silage (38% DM) + medium grain (MG); (2) 0.5% urea-treated corn (CU) silage (31% DM) + MG; (3) 2.2% ammonia-treated corn (AC) silage (32% DM) + MG; (4) AC silage + low grain (LG) were fed to eight Holstein cows in a latin square design. Silage DM consumption, milk production and milk composition were not different (P > 0.05) among treatments. Reducing the level of grain feeding from 32 to 23% of the diet with ammonia-treated corn silage resulted in a decrease (P
