CONCLUSIONS
Distillers grains, CGF, or a combination of both co-products, offer many feeding options to producers when included in feedlot diets. These co-product feeds may effectively improve cattle performance and operation profitability. WDGS and WCGF have feeding values greater than DRC in beef finishing diets. Drying appears to reduce the feeding value of co-products.The ability to keep cattle on feed and acidosis control are likely responsible for the higher apparent feeding values and may be the primary advantages of using WDGS and WCGF in feedlot diets. Understanding and managing variations in fat and sulfur levels in DGS products may help optimize DGS inclusion in feedlot diets. It appears that WDGS feeds better with HMC and DRC than with steam flaked corn.With feedlot cattle, more intense corn processing may be optimal for diets containing WCGF. It appears that WCGF is a complementary feedstuff for diets containing WDGS, SFC, HMC, and DRC. The quality and quantity of roughages may be minimized in finishing diets containing co-products. In the future, with increased supply of coproducts, feeding combinations of WDGS and WCGF may be advantageous.The high UIP value of the DGS and WCGF make them excellent protein sources for young, rapidly growing cattle and lactating cows. Alternate day (or three days/week) feeding appears to be feasible and DGS may have an advantage to grains, non-protein nitrogen sources, and more degradable protein sources in alternative day feeding systems. Innovative ways of storing wet products offer opportunities for smaller producers to capture the value of co-products feeds. It also appears that new co-products will be available in the future as the processes of making ethanol and other products from corn evolve.These new feeds should be evaluated with performance data to determine their respective feeding values.
