Corn co-products from the ethanol industry have become a common feed ingredient in Midwest feedlot diets. However, nutrient composition, especially moisture, can vary by as much as 15% from load to load even from the same ethanol plant. Knowing the exact moisture content of the co-product is advantageous for proper ration formulation and cattle efficiency. This study demonstrates that near infrared spectroscopy (NIRS) technology shows promise for rapid, accurate assessment of moisture in wet corn co-products.
