Proteins at low
GRASS silage protein levels are at their lowest level for seven years, according to silage analysis results from Frank Wright.
Protein levels have fallen from 13.2% last year to 12.6%, says the companys David Wilde. "Producers will need to compensate for lower silage protein by increasing the protein of concentrates this winter. But this will add £5-10/t to compound costs."
There is, however, some good news with average silage dry matter up from 27% last year to 31.8%, reducing silage production costs/t. Digestibility and energy values are also better than last year. "The lower silage production cost/t virtually offsets the extra cost of higher protein compound feed, helping to maintain margins this winter," explains Mr Wilde. *
