Use DDG to Supplement Grazed Corn Residue

By Cheryl Anderson , DTN Staff Reporter

Grazing corn residue can cut winter feeding costs, but feed supplements such as distillers grains are often necessary to supplement nutrients, according to an article by Grainnews.com (http://bit.ly/…).

The cornstalks, leaves, husks and some intact ears left after harvest provide about 50 pounds of total residue for grazing beef cows per bushel of corn harvest. Only about 25% of that is useable feed due to weather degradation and cattle wastage.

The feed value of stover is comparable to wheat or barley straw. So to support early to mid-gestation beef cows, nutrient supplements are necessary. Many producers supplement dried distillers grains to supplement energy and protein. Since DDG is 75% TDN and 28% crude protein, producers can add about 3.5 lbs. of DDG to raise a diet with 23 lbs. of residue from 5-8% protein.

Although more costly, distillers grains or molasses-based lick blocks can also be used for cattle grazing on corn stover fields.
