How to Make the Most of Straw Fermentation Starter
Straw fermentation starter is a powerful tool that can quickly and efficiently turn straw into high-quality animal feed. However, to achieve the best results, it's important to follow some key techniques. Let's take Jinbao straw fermentation starter as an example and explore how to use it effectively:
First, always ensure that the raw materials you use are fresh and free from rot or toxins. Using spoiled or contaminated straw can inhibit the growth of beneficial microorganisms, leading to poor fermentation quality.
Second, when stacking the straw, avoid compacting it too tightly. Good ventilation is essential for proper fermentation. If the pile becomes too dense, air circulation will be limited, which may result in bad odors or uneven fermentation.
Third, store the fermentation starter in a cool, dark place. Direct exposure to sunlight can damage the functional microbes, reducing their effectiveness. Always keep it away from light.
Fourth, different types of straw have varying nutrients and odors, which can affect the final taste of the fermented feed. To maximize nutritional value, consider mixing different straws. For example:
- Combine coarse and fine materials, such as adding about 10–15% cornmeal to the straw during fermentation.
- Mix different crop straws, like corn stalks and wheat straw, to create a more balanced nutrient profile.
- Adjust the feeding ratio based on the animals' needs. Fermented straw should be mixed with complete feed at the right proportions. Cows, sheep, ducks, and geese can eat it directly, while pigs and chickens should have it in smaller amounts.
The weight of each batch should not be less than 15 kg. Smaller batches may not generate enough heat, making it difficult to maintain consistent fermentation quality.
It’s best to use the fermented feed immediately after preparation. If storage is necessary, do not keep it for more than two days. If longer storage is required, use an anaerobic method—cool the material and seal it tightly. For small-scale farmers with just a few pigs or chickens, it's ideal to mix the straw with other ingredients like corn flour before fermenting. After fermentation, combine the fermented feed with concentrates and feed them together. This not only improves digestion but also helps reduce feed costs and waste.
