Treating grass silage with an effective biological inoculant will
improve nutritional value significantly across a wide range of
dry matters and cuttings dates, according to recent studies at
the Dutch research institute at Lelystad.
Reporting on his work at Wageningen UR at Alltech's recent
feed industry Symposium in Kentucky, USA, Dr Ad van Vuuren showed
that treatment of grass silage with the bacteria and enzyme inoculant
Sil-All4x4 led to the synthesis of 6% more microbial protein -
the best form for milk production - when compared with an untreated
A significant improvement in microbial protein was achieved at
three varying dry matters (20%, 30% and 50%), and at cutting dates
in May and September, indicating that valuable benefits are gained
under the vast majority of UK silage making conditions.
Extra feed value resulting from the Sil-All4x4 treatment was shown
in the Lelystad work to equate to significant additional milk production.
When interpreted under typical UK conditions, this extra feed value
would support an estimated 0.7 - 0.8 kg/cow/day of milk production,
which Alltech's European Forage Product Manager Matthew Smith says
makes the inoculant cost effective whatever the conditions.
"It is significant that these results remained consistent
across the full spectrum of conditions in the study, so farmers
can be more confident about a strategy of routine inoculant use," he
"The important thing for any farmer is to assess the value
of the extra production against the cost of the inoculant, bearing
in mind that improved feed value is only part of the story. The
true value of the inoculant should include increased production,
and also any savings in bought in feed and reduced ensiling losses."
