Wet Distillers Grains Plus Solubles or Solubles in Feedlot Diets Containing Wet Corn Gluten Feed

Effects of the addition of 0% to 40% wet distillers grains plus solubles (WDGS) or 0% to 20% condensed corn distillers solubles (CCDS) to feedlot diets containing high moisture corn (HMC) and 35% wet corn gluten feed (WCGF) were evaluated. As WDGS replaced HMC, average daily gain (ADG) decreased linearly and dry matter intake (DMI) tended to decrease. Replacement of HMC with WDGS in the 35% WCGF diet caused a linear decrease in ADG and a trend for a linear decrease in DMI. When CCDS replaced HMC, no difference in steer performance was observed. The sulfur content, rather than fat content, of WDGS may be the limiting factor with feeding WDGS in combination with WCGF, and solubles may effectively reduce the dietary inclusion of corn by up to 20% of diet DM in finishing diets containing 35% WCGF.
