Wet distillers grains (WDGS) price

Wet distillers grains (WDGS) are a protein feed, fed to raise a ration's crude-protein content. They are priced and tracked here, but they are not scored on the nutrient-cost screening board: no dry-matter-basis nutrient coefficient for them was verified against a primary extension or NRC table at build, and this site never guesses a coefficient. Prices are quoted per ton, and the cheapest board price is not the cheapest fed price once freight and moisture are counted (see the FOB-vs-delivered guide). Wet distillers grains are the same corn co-product as DDGS, pulled off the same dry-grind ethanol plants before the dryer and sold wet, at somewhere around two-thirds moisture. Because most of the ton is water, freight economics rule this market in a way they do not for the dried product: WDGS only pays within a short truck haul of its plant, so the market is local and plant-specific rather than national. Feedlots and dairies within range often contract for a steady daily supply, since a plant cannot stockpile wet cake the way it can bagged or bulk DDGS. When natural gas prices for drying rise, plants lean toward selling wet instead.

The wet discount is the dryer the plant did not run. Selling wet skips the drying step entirely. USDA's Economic Research Service notes that removing moisture takes large, capital-intensive dryers and raises energy costs, and that drying costs account for most of the price gap between co-products that differ only in moisture. So the wet price is argued against the dried one. North Dakota State University Extension values wet grains by carrying a dried-grains value over to the wet product's dry matter, then allowing for delivery, storage, handling and possible spoilage. The wet vs dry distillers grains guide works through that comparison.

Most of the load is water, and it does not travel. Plants sell wet cake at 60 to 65 percent water, or a modified wet cake near 50 percent, per NDSU Extension. University of Georgia Extension notes wet grains can mold in transit and calls them most practical within a 30 to 35 mile radius of the plant. ERS puts the plant's best case plainly: ship large volumes of high-moisture feed short distances, skipping the dryer while holding spoilage down. Plants also need product gone quickly to make room for the next batch and keep ethanol output at its peak, so a steady nearby taker is worth something to the seller.

Shelf life runs in days, and summer shortens it. NDSU puts the wet material's shelf life at under seven days in warm weather and two to three weeks in colder weather. UGA notes Georgia heat and humidity can cut it to two or three days at the height of summer without preservatives or special storage, and ERS flags moisture-driven spoilage and nutrient loss as worst when temperatures are higher. That is the market's documented seasonal edge: a summer buyer carries more shrink risk per ton and needs more frequent loads, while bunkers, trench silos and plastic silage bags let feeders hold wet product longer.

Feedlots near the plant are the anchor buyer. ERS found cattle feeders reported paying less for co-products than dairy, hog and cow-calf operations, used the wettest products and were twice as likely to order straight from the plant. University of Nebraska-Lincoln beef research gives them a reason: for finishing cattle, wet distillers grains carry the highest feeding value, followed by modified and then dried. Dairies take wet grains too, best bought fresh every five to seven days per NDSU's dairy specialist. Terms vary by region: ERS notes most livestock producers buy co-products on the spot market, while a study of Nebraska feeders, who sit close to plants, found most of their co-product sold on fixed-price annual contracts.
