Corn Dried Distillers’ Grains with Solubles
Date Issued: September 25, 2017
DescriptionCorn Dried Distillers’ Grains with Solubles (DDGS) is the feed product obtained after distillation of the ethyl alcohol from the yeast fermentation of corn. The coarse grain fraction of the whole stillage is separated by centrifugation and dried by methods employed in the grain distilling industry to the specifcations listed below. The feed is rich in cereal and residual yeast proteins, energy, minerals, vitamins and growth factors. The product is moderately coarse, friable and a golden to brownish colour. Fermentation of the starch, which is about 2/3 of the weight of cereal grains, results in a threefold concentration of non-starches such as proteins, fats, mineral and vitamins in the residual mash. In addition to these nutrients, protein, vitamins and growth factors are further synthesized by the growing yeast cells during the fermentative process.

Analytical MethodsThe AFIA recommends the following methods for the major components of distillers’ grains.
Storage and HandlingDDGS are handled in a manner like other dry feed bulk commodities; namely stored in free-flowing overhead bins, or some form of sheltered flat storage. The product flows easily or can be conveyed from bins, and also handled by usual front-end loader technique. Corn DDGS can be combined into a total mixed ration, or top dressed and fed accordingly.
Use and ApplicationDDGS are an excellent protein and energy source for all ruminants, and can readily comprise 20 – 30% of the total ration dry matter. In the rumen, Digestible Intake Proteins (DIP) are degraded by microbes, while the Undegradable Intake Protein (UIP) remains intact and “by-passes”, becoming available for digestion and absorption in the lower tract. Protein in Corn DDGS is a natural protein and recognized as a feedstuff with one of the higher proportions of by-pass protein. Corn DDGS are also an excellent source of energy and other essential nutrients. Like all feedstuffs, Corn DDGS should be properly incorporated into a ration/ complete feed, or preferably a total mixed ration (TMR) for ruminants. Consult your nutritionist and/or veterinarian to insure the proper balance and levels of the required nutrients in the complete ration.
