In a three-year study, corn-dried distillers grains plus solubles (DDGS) were evaluated as a substitute for forage and nitrogen (N) fertilizer in yearling steers grazing smooth bromegrass in eastern Nebraska. Stocking rate increased with N fertilization and DDGS, and average daily gain (ADG) increased with DDGS. Total gain per acre increased by 53% with N fertilization and 105% with DDGS supplementation. N use efficiency was 139% greater per acre with DDGS supplementation compared to fertilizing with N alone. Feedlot ADG was similar among treatments with steers maintaining their BW advantage through the finishing phase.
