Corn Distillers Dried Grains with Solubles in Rations for High-Producing Hens

Abstract

SLOAN (1940) reported that a special distillers dried grains with solubles (solvent extracted) fed in combination with meat scraps and soybean meal could satisfactorily contribute one-fourth of the protein in a chick starting ration. When fed at a 30 percent level as the only protein supplement, growth was unsatisfactory. Sloan (1941) extended these findings and found that distillers dried grains with solubles could be substituted on a weight for weight basis for dried skim milk as a source of riboflavin. In this latter study he concluded that this material could comprise 12 to 15 percent of the total crude protein in rations for growing chicks and laying hens. D’Ercole et al., 1939; Shea et al., 1941; Dickens et al., 1941; Parkhurst et al., 1942, 1945; and Nelson et al., 1944; confirmed and extended the observations of Sloan. These workers showed that distillers dried grains with solubles was a source of …
