Here in mid-winter, cornstalks remain a great forage resource for livestock producers. So far, snow cover on cornstalks has been minimal, or what snow has fallen has mostly melted off. While cattle can graze with snow cover, remember that if an icy crust develops on the snow, this will limit grazing and supplemental feed may need to be provided.
