Comparing Dry, Wet, or Modified Distillers Grains Plus Solubles on Feedlot Cattle Performance
A University of Nebraska–Lincoln pen mean meta-analysis (2011 Nebraska Beef Cattle Report, pp. 40-41) determined a feeding value for wet distillers grains plus solubles (WDGS), modified distillers grains plus solubles (MDGS), and dried distillers grains plus solubles (DDGS) relative to dry-rolled corn (DRC) in feedlot diets. The feeding value for WDGS is 143 - 130%, 124 - 117% for MDGS, and 112% for DDGS. However, little research has been conducted comparing WDGS, DDGS, and MDGS in the same study. Therefore, the objective of this study was to compare the effects of drying ethanol co-products produced from the dry milling process on feedlot cattle performance by feeding WDGS, MDGS, and DDGS in the same study.
