Distillers’ dried grains with solubles (DDGS) are a protein- and energy-rich feed ingredient produced by grain ethanol plants. FUSHKOV GCG supplies DDGS to feed manufacturers and livestock producers worldwide on Incoterms 2020 terms.
In dry-grind ethanol production, grain starch is fermented into ethanol. The remaining protein, fat, fibre and minerals are concentrated roughly threefold compared with the original grain. The wet grains are combined with the condensed solubles and dried to produce DDGS, a golden to brown free-flowing meal or pellet. Most DDGS in world trade is made from corn (maize); wheat-based DDGS is produced in some regions. The United States is by far the largest exporter.
| Parameter | Typical value |
|---|---|
| Moisture, max | 12% |
| Crude protein | Typically 26–30% (corn DDGS) |
| Crude fat | Typically 5–10%, depending on oil extraction |
| Protein + fat (profat), min | As agreed in the contract |
| Crude fibre | Typically 7–9% |
| Colour | Golden to light brown; dark colour may indicate heat damage |
| Mycotoxins | Within the limits of the destination country |
| HS code | 2303 30 |
Reference values for typical commercial grades. The final specification is fixed in the contract; the final classification of a lot is confirmed by the customs declarant.
DDGS is used in rations for dairy and beef cattle, pigs, poultry and aquaculture, partly replacing maize and soybean meal as a source of energy and protein. It is especially valued in ruminant feed, where its digestible fibre and bypass protein are used efficiently. Major import markets include feed manufacturers in Asia, the Middle East, Mexico and Europe.
DDGS is shipped in bulk in vessel holds, in bulk in containers lined for the cargo, and in big bags or bags, by sea, rail or multimodal routes. Pelleted DDGS flows better and is less prone to caking than meal-form product during long voyages.
Profat is the combined content of crude protein and crude fat. It is a common commercial parameter for DDGS, because plants that extract more oil produce DDGS with lower fat.
Colour is used as a quick indicator of drying conditions. Golden DDGS usually has better amino acid digestibility, while very dark product may have been overheated, which reduces lysine availability.
Brewing or distilling dregs and waste, including DDGS, are classified under HS 2303 30. The final classification of a lot is confirmed by the customs declarant.
