1DDGS-HPLincolnway and DDGS-CV were used in both experiments, whereas corn was used only in Exp 2.
2DDGS-HPLincolnway = high-protein distillers dried grains with solubles from Lincolnway Energy; DDGS-CV = conventional distillers dried grains with solubles.
3IDF = insoluble dietary fiber; SDF = soluble dietary fiber; TDF = total dietary fiber.
4AEE = acid hydrolyzed ether extract.
