Abstract

A meta-analysis of UNL feedlot trials replacing dry-rolled or high-moisture corn with wet distillers grains plus solubles (WDGS) indicated WDGS fed between 15% to 40% of diet DM was 130% the feeding value of corn. Feed: Gain, ADG, marbling score, and fat thickness responded quadratically as WDGS inclusion increased. In most cases, performance and carcass characteristics improved up to 30% to 40%, then gradually decreased. Feeding WDGS up to 40% of diet DM improved performance and quality grade.
