University of Illinois research reports that swine producers can feed distiller’s dried grain with solubles (DDGS) to their pigs without concern for sulfur content.
“When you buy DDGS, you don’t have to be concerned about the level of sulfur it contains because there doesn’t appear to be any impact on pig performance,” said U of I animal sciences professor Hans Stein.
According to the researcher, DDGS, a co-product of the ethanol industry, is used as a feed ingredient in diets fed to swine.
To maintain a stable pH in fermentation vats, ethanol producers use sulfuric acid, which results in a sulfur content in the DDGS that varies according to how much sulfuric acid was used. Until now, the effect of low levels of sulfur in the diet on growth performance in pigs fed DDGS had not been determined, he said.
“Sulfur is toxic to cattle. If there is 0.4% sulfur in the diet, cattle start getting sick,” Stein said.… Continue readingRead More »
