Corn Distiller’s Dried Grains with Soluble (DDGS) is the dried residue remaining after the starch fraction of maize is fermented with yeasts to produce ethanol. Following fermentation, the ethanol is removed by distillation and the remaining fermentation residues are dried.

Corn DDGS is valuable feed ingredients, rich in protein, moderately rich in fat and can be fed to all classes of livestock as it contains approximately 85% of the energy value in corn.

Corn DDGS is more efficient ingredient than maize grain in cattle, poultry and fish diet and has shown to decrease methane produce from enteric fermentation when they replace it.
