Title: Assessment of Corn Distillers Dried Grains with Solubles (DDGS) from Ethanol Production on Performance and Carcass Quality of Growing-Finishing Swine – NPB #07-152 Investigator:

At each station, fortified corn-soybean meal diets containing 0, 15, 30 or 45% DDGS were fed to growingfinishing pigs in three phases. A common source of DDGS analyzing 26.3% crude protein, 0.96% lysine, and 9.7% fat was used at each station. Diets were formulated to contain 0.83, 0.70, and 0.58% true ileal digestible lysine during the three phases with diets changed at 133 and 200 lb, respectively. The DDGS replaced corn and soybean meal, and crystalline lysine and tryptophan were added to maintain constant true ileal digestible levels of the amino acids in each phase. At each station, two pigs from each pen in two replications were killed for carcass and belly flex measurements. A midline backfat core also was obtained for fatty acid analysis and determination of iodine values.
