The Ultimate Guide: Proper Ways to Store Spent Grain for Cattle Feeding

If you’re a brewer, you know that spent grain is an inevitable part of the brewing process. While it may be tempting to toss this byproduct, did you know that it can make for great cattle feed? In fact, spent grain is high in protein and fiber, making it a nutritious addition to any bovine’s diet. That being said, proper storage techniques are essential when it comes to safely feeding your cows spent grain.

The importance of storing spent grain correctly

Spent grains are essentially wet mash after the brewing process has removed all the fermentable sugars. Because of its high moisture content (upwards of 80%), if not stored properly, spent grain can quickly become rancid and moldy which could lead to botulism or other health issues in cattle.

Storing on-site vs off-site

You have two options when it comes to storing your excess spent grains: on-site or off-site.
On-site storage means keeping the leftover mash right at your brewery location while off-site refers to having another facility store them for you. Both options have their pros and cons depending on how much space you have available on site as well as what kind of relationship is established with local farmers.

How should I store my Spent Grain?

Drying out Spent Grain before Storage

Before storing away those buckets fulls or bags brimming with moist fibrous material from your latest batch just laying around like sleeping giants waiting patiently for their chance back into life again; they must first go through a drying process so that they don’t rot too soon due excessive moisture content inside each piece individually composed! This will involve spreading them evenly over some kind flat surface allowing air circulation around every inch then let them dry naturally under direct sunlight for about 4-5 hours before transferring them into airtight containers.

Air-tight Containers

Once the spent grains are dry, they can be stored in airtight containers until you’re ready to use them. Ensure that the container is clean and completely sealed to avoid moisture buildup inside which could lead to mold growth.

Labeling & Expiration Dates

Before storing, always make sure to label your storage containers with information regarding when it was packaged and how long you can store it safely. A clear expiration date will also ensure that you don’t end up feeding your cattle rancid feed by mistake.

Conclusion

Storing spent grain may seem like an afterthought when compared with the brewing process itself, but proper storage is key if you want to reuse this valuable byproduct as cattle feed. Drying out and sealing in air-tight containers is essential for ensuring that the spent grain stays fresh for longer periods while providing all of its nutritional benefits. By following these simple instructions on how best store your spent grain, not only will you save money on expensive feeds but also contribute positively towards sustainable livestock farming practices!
