Mastering the Methods for Making Silage Feed
Grasses, legumes, and various green crops can all be used as silage feed. Not only does this improve feed quality, but it also enhances overall utilization. In today's environment where feed is expensive and in short supply, silage is a highly cost-effective solution. But how can we maximize its efficiency? Here are some practical methods to consider.
Using a silage starter like Goldbaby Type II can make the process fast, safe, and easy to learn. The key to success lies in mastering the "four essentials":
**1. Quality of Raw Materials**
First and foremost, timing is crucial. Forages and crops have varying nutritional values depending on their growth stage. Grasses should be harvested at the heading stage, while legumes are best cut during the bud stage. Additionally, selecting materials with higher sugar content is essential. Lactic acid bacteria need about 1% to 5% sugar to thrive, creating an ideal environment for fermentation. Legumes tend to be high in protein but low in sugar, so they’re often dried in the sun before use. To balance this, mix them with other high-sugar green feeds for better results.
**2. Moisture Content**
Maintaining the right moisture level is critical for successful silage. The ideal range is 65% to 75%, which supports optimal fermentation and minimizes dry matter loss. To check moisture: take a handful of material, squeeze it tightly for one minute, then release. If juice comes out, the moisture is over 75%. If it holds its shape without dripping, it’s between 70% and 75%. If it feels elastic and slowly loosens, it’s around 55% to 65%. If it falls apart immediately, the moisture is below 50%.
**3. Anaerobic Conditions**
Creating an anaerobic environment is vital. It allows lactic acid bacteria to multiply, producing lactic acid that inhibits harmful microbes and preserves nutrients. To achieve this, chop or crush the raw materials, press them tightly, and seal the silage immediately after filling. Regularly inspect the pits to prevent air leaks, which can ruin the batch.
**4. Proper Operation**
When using a silage starter like Goldbaby Type II, the dosage is 1 kg per ton of raw material. Mix the starter with corn flour in a 1:5 ratio (1 kg starter + 5 kg corn flour), then spread the silage in layers about 20 cm thick. After filling, sprinkle the mixture evenly and seal the silage. Adding a fermentation aid isn’t just optional—it helps eliminate oxygen quickly, forming a perfect anaerobic environment. This not only increases success rates but also reduces losses from improper handling, saving time and effort.
