Distillers Dried Grains

Distillers Dried Grains with Solubles is the product obtained by condensing and drying the stillage remaining after the removal of ethyl alcohol by distillation from a yeast fermentation of grain or grain mixture. The coarse fibrous material is separated from the soluble and finely suspended portion by a centrifuge. The liquid fraction is concentrated by evaporation to a syrup which is then combined with

the coarse fibrous fraction and dried in heated air dryers. The feed is rich in cereal and residual yeast proteins, proteins, energy, minerals, B-vitamins and growth factors. Fermentation of the starch results in a three fold concentration of nonstarches such as proteins, fats, minerals and vitamins. In addition protein, vitamins and growth factors are further synthesized by the growing yeast cells during the fermentation process and are included in the dry residue.

The product flows or can be conveyed from bins or handles by the usual front end loader technique. Distillers Dried Grains can either be combined into a total mixed ration or topdressed and fed accordingly.

USE AND APPLICATION
Distillers Dried Grains are an excellent protein and energy source for all ruminants and can readily comprise 15 – 20% of the ration dry matter (6 to 8 pounds per head per day, maximum). Consult with a nutritionist for proper feeding recommendations. It is a medium protein feed with 120% of the energy value of

ground corn. The protein in Distillers Dried Grains is a natural protein and recognized as a feedstuff with one of the highest proportions of digestible insoluble protein.one of the highest proportions of digestible insoluble protein. It is a very palatable feed, is safe to feed in large quantities and may be included in the grain mix at high levels.
