Summary of the Value of Distillers Grains Plus Solubles for Feedlot Cattle

Summary with Implications An analysis of over 6,100 head of finishing cattle across 50 experiments was conducted to determine the feeding value of full-fat and de-oiled distillers grains. This analysis was limited to studies where dry-rolled corn, high-moisture corn, or a combination of the two corn processing methods were displaced by 15% or more distillers grains. Dry distillers grains plus solubles (DDGS), modified distillers grains plus solubles (MDGS), and wet distillers grains plus solubles (WDGS) were evaluated as either full-fat or de-oiled. The feeding value of distillers grains was assessed relative to a corn-based control diet containing no distillers. Results indicate that removing fat from distillers grains reduces its feeding value by 8 percentage units, from 120.7% to 112.8%, across all distillers types. Additionally, feeding WDGS results in improved feed conversions compared to MDGS which is improved compared to DDGS.
