Crop residues are great forage, but snow and ice can impact nutrition and how animals graze. #Nfield— Ben Beckman (@HuskerHerdsman) November 14, 2020
Too much snow and ice limits grazing
Moisture leaches nutrients, energy first
Muddy fields = trampling and fouling@UNL_CropWatch @UNLBeef @ForagesGuy @CropTalkMegan pic.twitter.com/qGn6hgRISn

Pull animals tonight.
Wait 5-7 days from the last frost before grazing again.
New shoots are also a danger, pull animals if present. pic.twitter.com/AWUrzv05Vd

Do not harvest after a soft frost (30-32°F)of stored reserves
Need forage, wait for a killing frost (24-29°F) @UNL_CropWatch @HuskerHerdsman @ForagesGuy @Pasture_Forage pic.twitter.com/37JZ93RJCf
