Summary and Implications
Feed co-products from the ethanol industry are readily available in the state of Iowa and are a high protein and energy product. Cornstalk grazing is utilized by Iowa cow-calf producers each year in the fall according to ISU-IRMSPA records at the rate of 1.9 acres per cow with a grazing period length of approximately 45 days. Extending this cornstalk grazing period would assist producers in lowering their total annual feed cost.
