Ventilation: Essential for the Proper Functioning of the Fermentation Bed!

I. Basic Conditions for the Normal Operation of the Fermentation Bed
After the ecological fermentation bed is built, the next step is to start and maintain it. With the use of the Fermentation Bed Activator, it can be started within 1-3 days during summer, while in cold winters with temperatures as low as -10°C or even lower, a well-insulated environment can still allow startup within 3-5 days. This shows that the Jinbao Fermentation Bed is easy to start and not significantly affected by seasonal climate. However, the key lies in daily management and post-operation maintenance. To ensure the smooth operation of the fermentation bed, it's crucial to understand its basic requirements: microbial species, litter thickness, moisture content, temperature, nutrients (provided by animal waste), and most importantly, ventilation. Microorganisms are the core of the process, as they break down pig waste through their biological activities. The types, activity levels, and number of beneficial bacteria all play a vital role. The Jinbao Fermentation Bed contains over a dozen functional microorganisms, with more than 3.5 billion viable cells per gram, ensuring strong bacterial activity. Moisture is also critical, as the ideal water content in the bedding should be around 60%. Too much or too little moisture can hinder decomposition. Litter thickness is another important factor—Jinbao requires 50 cm, while other systems often need 80–100 cm. If the thickness is too low, the "core fermentation layer" becomes a "protective layer," reducing the space for bacteria to thrive and leading to reduced efficiency or failure of the system. Temperature has a minor impact on the already activated fermentation bed but significantly affects pig health. Extreme temperatures can reduce feed intake and growth. Therefore, proper ventilation is essential to maintain a stable and safe environment.II. Negative Consequences of Poor Ventilation in the Fermentation Bed
Poor ventilation directly impacts bacterial vitality, moisture, and temperature inside the house. Here are some common issues: 1. **Slow or No Decomposition of Feces**: Inadequate airflow leads to low heat and poor microbial activity, as most bacteria in the system are aerobic. Without enough oxygen, decomposition slows down, leading to fecal buildup, high ammonia, and carbon dioxide levels. Anaerobic bacteria then dominate, producing harmful gases like hydrogen sulfide and ammonia, which irritate pigs' respiratory systems, causing diseases and stunted growth. 2. **Increased Humidity and Water Droplets**: During operation, water vapor and COâ‚‚ are produced. Without proper ventilation, these gases accumulate, causing condensation on ceilings and walls, especially in winter. This moisture can lead to wet bedding, killing beneficial bacteria, and promoting fly larvae and cold-related illnesses in pigs. 3. **Unstable Temperatures**: Poor ventilation in winter prevents the house from warming up, making pigs prone to colds. In summer, lack of airflow causes heat buildup, excessive COâ‚‚, and ammonia, affecting pig health and growth.III. Effective Measures to Improve Ventilation
Ventilation depends on many factors, including season, region, and climate. It’s important to adapt strategies accordingly to promote healthy pig growth. 1. **Optimize Building Design**: Pens should ideally face south, have proper height and span, and be located on elevated ground. These structural considerations help improve air circulation naturally. 2. **Ensure Complete "Four Windows"**: For large farms, skylights, windows, and exhaust fans should be installed to facilitate both natural and mechanical ventilation. Small-scale farmers can use regular windows and skylights. Opening windows during midday in winter and using fans in hot weather helps manage temperature and gas levels. 3. **Regular Turning of the Litter**: Tumbling the bedding improves aeration and reduces compaction, preventing anaerobic conditions. It also helps remove excess moisture, especially in summer, when quick drying is crucial. 4. **Replace Concrete Partitions with Iron Fences**: Using iron fences instead of concrete walls enhances air flow and reduces dead zones where harmful gases accumulate. Proper ventilation, combined with other maintenance practices, ensures the safe and stable operation of the fermentation bed.
