For feedlots close to ethanol plants, wet distillers’ grains can cost-effectively substitute for some corn in finishing rations. In a trial reported in the University of Nebraska’s 2007 Beef Cattle Report, researchers tested various levels of wet distillers’ grains with solubles in rations that also contained 30 percent wet corn gluten feed.

The researchers included WDGS at 0, 10, 15, 20, 25 and 30 percent of dry matter in the rations, using a dry-rolled corn/high moisture corn-based ration as a control. Using 30 percent wet corn gluten feed in the diets significantly increased dry matter intake, average daily gain and feed conversion compared to the control diet. Intake and daily gains were highest with the rations containing 15 to 25 percent WDGS and declined slightly at the 30 percent level. The level of WDGS did not appear to affect feed conversion.
