Keys for Cornstalk Grazing

By Aaron Berger

Nebraska has 10.5 million corn acres and 1.5 million beef cows — more than enough acres of corn residue for grazing beef cows through the winter.

Scouting fields before grazing is important to determine the amount of corn present and to look for spilled corn that could cause grain overload, which could result in cattle bloat or death. If there are more than 8-10 bushels of corn on the ground per acre as ears of corn, a grazing strategy to control corn intake will need to be used to minimize grain overload risk. 

When there is a minimum of ears of corn on the ground, the number of cattle to be grazed and the length of time for grazing should be determined based on corn bushel yield per acre and the average weight of cattle. The UNL Corn Stalk Grazing Calculator is an Excel® spreadsheet that can be used to calculate this.
