The global distiller's grain market is witnessing robust growth, driven by the expanding ethanol industry and rising demand for cost-effective, nutrient-rich animal feed. According to Fortune Business Insights, the global distillers grain market size was valued at USD 17.42 billion in 2025 and is projected to grow from USD 18.81 billion in 2026 to USD 34.72 billion by 2034, exhibiting a CAGR of 7.96% during the forecast period.
Distiller's grain is a co-product of ethanol production, generated after starch is extracted from grains like corn and wheat during the fermentation process. The remaining material is rich in protein, fat, fiber, and phosphorous, making it a highly valuable feed ingredient for livestock. It is available in three primary forms — Wet Distillers Grain (WDG), Dried Distillers Grain (DDG), and Dried Distillers Grain with Solubles (DDGS) — each varying in nutritional content, shelf life, and ease of transport.
The surge in ethanol production across the globe is the primary growth driver for the distillers grain market. As ethanol output rises, so does the availability of distillers grain as a by-product. This has positioned distillers grain as a favorable and economical substitute for conventional feed ingredients like soybean meal, which carries a comparatively higher price tag.
Distiller's grain contains 25 to 35 percent crude protein, making it an effective source of energy and nutrition for livestock, especially during winter. Unlike conventional corn-based feed, distillers grain has starch removed, meaning its energy comes from digestible fiber — a healthier option for animal digestion. It also reduces the need for additional phosphorous supplements in livestock diets.
Growing global demand for quality milk, meat, and poultry products has further strengthened the market. The Food and Agriculture Organization (FAO) reported global meat consumption at around 325 million tonnes, highlighting the scale of the livestock feed industry. As dairy farms and poultry producers seek affordable, high-protein feed solutions, distillers grain has emerged as an attractive option.
Despite its advantages, the presence of sulfur in distillers grain can be harmful to the health of beef cattle if used without proper nutritional assessment. Additionally, wet distillers grain (WDG), while more nutritious, is difficult to store and can spoil within 5–7 days due to high moisture content. These factors require farm managers to carefully evaluate nutritional composition before incorporating distillers grain into animal diets.
The market is segmented by type into DDGS, DDG, and WDG. By source, corn dominates due to its widespread use as the primary feedstock in ethanol production. Corn-derived distillers grain is economical, widely available, and protein-rich. By livestock, the market covers ruminants, swine, poultry, and other animals, with ruminants and poultry holding significant demand shares.
North America leads the global distillers grain market, owing to its large-scale corn production and well-established ethanol industry. The United States is a major contributor, supported by free trade frameworks like the North American Free Trade Agreement (NAFTA), which facilitates cross-border trade of distillers grain between the U.S. and Canada. The expansion of ethanol plants across the region continues to increase supply and improve cost-effectiveness of the product for livestock producers.
Leading companies in the global distillers grain market include Green Plains Inc., Pacific Ethanol Inc., Flint Hills Resources, Valero, CropEnergies AG, ADM, Husky Energy, Bunge Limited, Purina Animal Nutrition, Poet LLC, Didion Milling Inc., and Greenfield Global. These players are actively expanding production capacities and innovating product forms to meet growing demand.
Q1. What is the size and share of the distillers grain market? The global distillers grain market was valued at USD 17.42 billion in 2025 and is projected to reach USD 34.72 billion by 2034, growing at a CAGR of 7.96%. North America holds the largest regional market share due to its dominance in corn and ethanol production.
Q2. What are the major types of distillers grain? The three primary types are Wet Distillers Grain (WDG), Dried Distillers Grain (DDG), and Dried Distillers Grain with Solubles (DDGS). DDGS are easier to transport and store, while WDG offers higher nutritional value but a shorter shelf life of 5–7 days.
Q3. What is driving the growth of the distillers grain market? The key growth drivers include rising global ethanol production, increasing demand for affordable livestock feed, and the expanding dairy and poultry industries. The high protein and fiber content of distillers grain makes it a cost-effective substitute for expensive feed ingredients like soybean meal.
