Mastering the method of making silage fermentation feed
Silage fermentation is an effective method to preserve green forage, such as grasses, legumes, and other green manures. Not only does it enhance the nutritional value of the feed, but it also improves its overall utilization. In today’s environment where feed is both expensive and scarce, silage offers a cost-effective solution. But how can we maximize the efficiency of this process? Here are some practical methods to improve the utilization rate of silage.
Using a silage starter like Goldbaby Type II makes the process faster, safer, and easier to master. To achieve the best results, there are four key factors to consider:
**1. Quality of Raw Materials**
First, it's crucial to harvest the forage at the right time. The nutritional content varies greatly depending on the growth stage of the plant. Grasses should be harvested at the heading stage, while legumes are best collected during the budding stage. Additionally, selecting materials with high sugar content is essential. Lactic acid bacteria need about 1% to 5% sugar to multiply rapidly and create a good silage environment. Legumes tend to have more protein but less sugar, so they are often dried in the sun before being mixed with other high-sugar forages to balance the composition.
**2. Moisture Content**
Moisture level plays a critical role in successful silage. The ideal moisture range is between 65% and 75%. A simple way to check is to grab a handful of material, squeeze it tightly for a minute, and then release it. If juice comes out, the moisture is over 75%. If it holds its shape without dripping, it's around 70%-75%. If the material feels elastic and slowly loosens, that's 55%-65%, and if it falls apart immediately, the moisture is below 50%.
**3. Anaerobic Conditions**
Creating an anaerobic environment is vital for promoting lactic acid bacteria activity. This helps suppress harmful bacteria and preserves nutrients. To achieve this, the raw materials should be chopped or crushed, then compacted and sealed immediately after filling. It’s also important to regularly check silage pits for air leaks, as even small gaps can spoil the process.
**4. Proper Operation**
When using the Goldbaby Type II starter, mix 1 kg of the starter with 5 kg of Corn flour (a 1:5 ratio). Spread the silage in layers about 20 cm thick, and sprinkle the mixture evenly. After all the material is in place, apply the final layer of the starter mixture and seal it tightly. Adding a fermentation aid like Goldbaby not only speeds up the process but also reduces the risk of failure due to improper handling, saving time, labor, and resources.
By following these steps, you can significantly improve the quality and success rate of your silage, making it a valuable and sustainable feed source for livestock.
