Four functions of silage fermentation feed
Silage fermentation is a highly effective method of preserving and enhancing the quality of animal feed. Compared to direct drying and feeding of straw, silage offers several significant advantages that make it a preferred choice for farmers and livestock producers. Here are four key functions of silage fermentation:
1. **Nutrient Preservation**: When feed is stored through traditional methods like haying, it often leads to substantial nutrient loss due to exposure to sunlight, rain, and air. For example, during the haying process, up to 30-40% of nutrients can be lost. In contrast, silage fermentation minimizes these losses by creating an anaerobic environment that preserves most of the nutrients. Dry matter loss in silage is typically around 10%, making it a more efficient way to retain the nutritional value of the feed.
2. **Extended Green Feeding Season**: Fresh green feed is ideal for livestock, but its availability is limited by seasonal changes. In regions like the northwest of China, the green feeding season may last less than six months, leaving animals without adequate nutrition during the winter. By using silage fermentation, farmers can store high-quality feed for long periods, ensuring a steady supply of nutritious feed throughout the year. This helps maintain consistent animal health and productivity.
3. **Improved Palatability and Digestibility**: During the silage fermentation process, lactic acid bacteria produce lactic acid, which gives the feed a pleasant aroma and makes it soft and juicy. This not only enhances the taste but also encourages animals to eat more. Additionally, the fermentation process breaks down complex plant materials, making the feed easier to digest. Studies have shown that silage improves the digestibility of feed, as demonstrated in Table 1 below:
| Feed Type | Dry Matter (%) | Crude Protein (%) | Crude Fat (%) | Ammonia-Free Extract (%) | Crude Fiber (%) |
|---|---|---|---|---|---|
| Hay | 65 | 62 | 53 | 71 | 65 |
| Silage | 74 | 73 | 70 | 75 | 72 |
4. **Convenient and Durable Storage**: Silage fermentation using products like Jinbao is simple and efficient. Once properly fermented, silage can be stored for long periods without spoiling, provided it remains sealed. Unlike hay, which is sensitive to weather conditions, silage is not affected by rain or sun. It also takes up less storage space and is safer to handle. This makes it an ideal solution for farmers looking to optimize their feed management and reduce waste.
