The domestic processing of corn to produce high-fructose corn syrup has made available an increasing amount of corn gluten feed. In many locations in Kentucky, corn gluten feed is one of the few and most economical by-product or co-product feeds available. Used correctly, corn gluten feed is an excellent supplement for forage-based programs. Corn gluten feed is produced from the wet milling of corn. The corn is soaked in sulfurous acid. The resulting steep liquor contains protein, minerals, vitamins and energy sources. The oil and starch are extracted from the swollen kernels. The remaining fiber (bran) is then mixed with the steep liquor to create wet corn gluten feed. The amount of steep liquor inclusion affects both the color and nutrient content of the final product. The wet corn gluten feed can then be dried from 40 percent dry matter to 90 percent to create the dry product which is most commonly available across the state.
