**Production and Maintenance of Fermentation Beds**
Fermentation beds are an essential part of modern pig farming, offering a natural and efficient way to manage waste while promoting a healthier environment for both animals and farmers. The design and maintenance of these beds play a crucial role in ensuring their effectiveness and longevity.
The structure of the pigsty should be oriented east-west and face south to maximize sunlight exposure and optimize temperature regulation. Depending on local conditions, the building can be designed as a greenhouse or single- or double-row style. For better air circulation, it's recommended to install "four windows complete"—including skylights, underground vents, regular windows, and windbreaks. These features help maintain fresh air flow, prevent bad odors from accumulating in corners, and ensure smooth movement of air throughout the space.
The size of the fermentation bed should be carefully planned. A recommended area is between 20 to 45 square meters, which helps avoid common issues like "bad beds," "blisters," or "mud beds." Additionally, if the site allows, building the bed partially or fully underground can help prevent water seepage and maintain stable internal conditions.
When producing a fermentation bed, such as the Gold Baby Fermentation Bed, the process is straightforward and user-friendly. It follows a "dry spread" method with simple steps: one dose of material and five layers of fungi. For example, to create a 20-square-meter bed, you first mix 2 kg of gold treasure compound (in a 5:1 ratio) with 10 kg of rice bran or corn flour, then divide it into four parts. Next, prepare 10 square meters of dry sawdust (at least 50 cm thick), also divided into five parts. Then, layer the sawdust and fungi—five layers of sawdust and four layers of fungi. Once the bed is ready, place the pigs inside without adding extra water. Each pig should have at least 1.2–1.5 square meters of space. Piglets may require slightly less space, but it should still be adequate. After two or three days, the fermentation process begins, breaking down the manure naturally.
Maintaining the fermentation bed is just as important as its initial setup. Proper care ensures that the system functions efficiently over time.
**Humidity Control**
Maintaining the right moisture level is critical. The humidity in the excrement, urine, and central layers should stay below 65%. A simple test is to grab a handful of the material—if no water drips from your fingers and there’s no visible moisture, it’s just right. Too dry or too wet conditions can hinder the fermentation process. If too dry, microbial activity slows down; if too wet, the temperature rises slowly, and poor ventilation may lead to anaerobic environments, causing bad smells or even "dead beds." A drainage slot should be installed under the water trough to remove excess moisture. Generally, the surface should be around 20–30% humidity, while the middle layer should be 50–65%.
**Regular Turning**
To ensure even decomposition, the litter should be turned regularly, about 20–30 cm deep, once or twice a week. This helps mix the materials and maintain consistent fermentation.
**Ventilation**
Good airflow is essential. Skylights help release ammonia and nitrogen dioxide, while ground and regular windows allow for vapor and moisture drainage. During hot weather, using an induced draft fan enhances air circulation. In summer, open the skylight during the day and close it at night. Adjusting ventilation based on the season and weather ensures the bed stays warm in winter and cool in summer.
**Litter Management**
Over time, the litter will settle, so it’s necessary to add more organic material and beneficial bacteria periodically. This keeps the litter layer at the proper thickness, maintaining the core fermentation layer, protective layer, and buffer layer. This not only extends the life of the bed but also ensures continuous effective waste breakdown.
By following these guidelines, farmers can successfully implement and maintain a healthy, sustainable fermentation bed system that benefits both the environment and animal welfare.
