Brought to you by Nebraska corn producers through their corn checkoff dollars— expanding demand for Nebraska corn and value-added corn products.


Corn milling co-products are expected to increase dramatically in supply as the ethanol industry expands. Distillers grains, corn gluten feed, or a combination of both co-products offer many feeding options when included in pasture and feedlot diets. These co-product feeds may effectively improve cattle performance and operation profitability. When these co-products are fed in feedlot diets, adjustments to grain processing method and roughage level may improve cattle performance. Innovative storage methods for wet co-products and the use of dried co-products offer small operations flexibility when utilizing co-products. As new co-products are developed by ethanol plants, they should be evaluated with performance data to determine their product-specific feeding values.
