Quality of grass silages varies extremely this year. Many silages were cut very early or late. Thus optimal quality of silages was not reached. Deficiencies in grass silage have to be balanced in rations, to further enable best milk performance.

Good grass silage usually shows 30-40 % dry matter and crude protein contents of 16-20 %. More than 13,5 % crude protein should be reached. Crude fibre content idally ranges between 22 and 25 percent.
