DDGS (Dried Distillers Grains with Solubles) is a byproduct obtained from the production of ethyl alcohol, primarily derived from grain crops such as corn, wheat, and barley. Although it originates as a “residual” material after fermentation and distillation, DDGS is, in fact, a valuable feed ingredient, rich in protein, fiber, and energy components. Here’s a closer look at its characteristics, benefits, and essential role in the modern circular economy.

How DDGS is Produced

  1. Fermentation and Distillation: The grains are milled and fermented with yeast, which convert starch into ethyl alcohol and carbon dioxide. The mixture is then distilled to separate the alcohol.

  2. Fraction Separation: The remaining “distillers grains” are split into solid particles (Distillers Grains) and a liquid fraction (Solubles).

  3. Blending and Drying: The liquid fraction is often concentrated and mixed back with the solids, then dried to about 10–12% moisture. This process produces DDGS, a stable product with a long shelf life.

Nutritional Advantages

  • High Protein Content: DDGS typically contains between 25% and 35% crude protein, making it an excellent alternative or supplement to other protein sources.

  • Energy and Fiber: Residual carbohydrates and fiber support better digestion and help maintain high productivity in livestock.

  • Vitamins and Minerals: Fermentation preserves important micronutrients that support animal growth and overall health.

Livestock Applications

  1. Ruminants (Cattle, Sheep): DDGS boosts milk production and promotes healthy rumen function, thanks to its fiber and high protein content.

  2. Swine: Up to 10–30% DDGS can be included in swine feed, with careful consideration of amino acid profiles and potential supplementation (e.g., lysine).

  3. Poultry: Broilers and laying hens can benefit from DDGS, provided that protein and energy levels are balanced to maintain optimal meat and egg quality.

  4. Aquaculture: Certain fish species can utilize DDGS in their diets when precisely formulated to meet their specific amino acid and fatty acid requirements.

Role in the Circular Economy

DDGS usage showcases an excellent example of repurposing “waste” materials. After extracting ethyl alcohol from grains, the remaining proteins and fibers are transformed into a high-value feed product. This reduces organic waste and conserves energy, thereby enhancing the overall sustainability of the production process.

Why Choose Essentica’s DDGS

Essentica employs advanced technologies and strict production controls to maintain consistent DDGS quality. Every batch undergoes laboratory tests for protein, fat, fiber, moisture, and mycotoxins. As a result, farmers receive a reliable product that enhances livestock feed formulations and contributes to better overall performance.

DDGS (Dried Distillers Grains with Solubles) is a valuable resource for livestock and an integral part of the circular economy. Combining high nutritional value with cost-effectiveness, DDGS helps producers reduce expenses and meet evolving sustainability requirements.
