Condensed Corn Distillers’ Solubles

Date Issued: September 25, 2017


Condensed Corn Distillers’ Solubles is obtained by removing the ethyl alcohol by distillation from the yeast fermentation of corn by condensing the thin stillage fraction to a semi-solid liquid. This product is rich in residual yeast proteins, energy, minerals, vitamins and growth factors.

Storage and Handling

Condensed Corn Distillers Solubles (CDS) is a 30% DM liquid, which needs to be stored in a clean sanitary tank, protected as practical from temperature extremes. Ideal minimum storage tank size should be 10,000 gallons. The liquid can be moved by pumping or gravity flow where conditions permit. Ideally CDS should be fed to animals (ruminants) in a TMR to ensure proper and uniform intake.

Use and Application

Condensed Corn Distillers Solubles are an excellent protein and energy source for all ruminants, and an inclusion rate of 20 – 30% of the total ration dry matter is recommended. 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 Condensed Corn Distillers’ Solubles is a natural protein and recognized as a feedstuff with one of the higher proportions of by-pass protein. In swine rations, typical inclusion rates are 10 – 15% on a dry matter basis. CDS has also been used as a sealant for bunker silo storage of forages and high moisture grains. Consult your nutritionist and/or veterinarian to insure the proper balance and levels of required nutrients in the animal’s complete ration.
