Mr. David Hagan:

Yes. When making silage out of multispecies swards, because the dry matter is lower in the herbs in the sward, it is necessary to just allow it to wilt that bit longer. The standard wilt time would be anywhere from 12 hours to 24 hours. In this case, we recommend at least 30 hours, if not 36 hours, of wilting time to get the dry matter up as best as is possible.
