    What Are Distillers Grains and Why Are They Important?

    What happens to grains that are used for the production of alcohol or ethanol? They aren’t simply thrown away.

    They become something quite useful, something that is referred to as distillers grains, which are extensively used for animal nutrition.

    They come mostly from corn, wheat, or barley. The grains are concentrated with energy, protein and other crucial nutrients, which makes them a good supplement for animal feed.

    These byproducts are fast becoming in demand. According to GMI Research, The Distillers Dried Grains with Solubles (DDGS) Market is anticipated to reach USD 18.4 billion in 2032. This illustrates the growing significance of these products in the agriculture and livestock sectors.

    How Distillers Grains Are Produced

    The process is fairly simple and here's how it can be broken down.

    First, grains are ground and mixed with water. Next, some enzymes are added to facilitate the conversion of starch to sugar. Then the fermentation begins.

    During this process, some sugars are converted to alcohol and carbon dioxide.

    Once the alcohol is removed by distillation, the material left is the solid residue, which is referred to as distillers grains.

    Straightforward operation. Intelligent use of by-products.

    Distillers Grains: What You Need to Know

    Not all distillers grains are created equal. However, they can typically be categorized into two basic types.

    Wet Distillers Grains (WDG)

    These have approximately 70% moisture content. Because of that, they have a short shelf life and need to be used quickly.

    Dried Distillers Grains with Solubles (DDGS)

    This is moisture WDG with moisture content of 10-12%, so it can be kept for a long time.

    When it comes to storage and transport, DDGS tends to be the preferred option.

    The Practical Side of DDGS in Animal Feed

    Right now, let’s get down to the facts.

    DDGS is a great source of protein, fiber, and fat. This nutritional trifecta makes it an excellent supplement for the feed of cattle, pigs, poultry, sheep and even fish.

    This nutritional supplement also positively imapcts growth, development and overall health of the animals.

    The final reason farmers choose DDGS is the price.

    DDGS is often cheaper than most traditional feed constituents. Hence, it provides nutrition without increasing costs excessively.

    The wide gap between quality and price is what makes the real difference.

    Analyzing DDGS options

    DDGS options available on the market originate from different sources such as corn and wheat. The most popular option is from corn.

    The process starts with the fermentation of corn starch, which is then separated to obtain the ethanol. The remaining content is then dried and can be utilized as livestock feed.

    DDGS from corn can be very effective due to the protein and fiber content. Because of such nutritional value, it is recommended to be included in all livestock feeds as an energy and protein providing supplement.

    In many situations, it can even substitute soybean meal in the feed, and no negative impacts will be observed in growth performance and meat quality. That is a huge bonus.

    Wheat DDGS

    Wheat DDGS is considered to be another strong option as it is produced similarly to corn DDGS, but uses wheat.

    It is also a good option as it is still high in protein and is a good feed constituent, especially for poultry and cattle.

    In comparison to corn DDGS, it might not be used as much but depending on the region and the availability, it is still very important.

    Conclusion

    The by products from the industry are often considered waste. However, in the case of distillery by products, they show that such materials can be useful. Used in livestock feed, the by products also help to reduce feed costs and overall efficiency.

    And with demand continuing to grow, DDGS is likely to remain a key part of the animal feed industry for years to come.
