Why Don’t We Need to Worry About Heat in Summer with Ecological Pig Raising?
Ecological fermentation bed farming is an innovative agricultural method that uses beneficial microorganisms as the central "converter" of energy and materials, based on microbiology, ecology, fermentation technology, and animal nutrition. The main idea behind this system is to continuously and efficiently transform animal waste and urine into useful substances and energy through a powerful and diverse microbial community. This process not only reduces pollution but also achieves zero emissions by completely breaking down pig waste. It's considered one of the most advanced and eco-friendly methods of livestock farming today. The success of this system depends largely on the construction and maintenance of the "fermentation bed." A well-managed fermentation bed ensures better economic returns and environmental sustainability.
There are two key principles behind this approach. First, the principle of air circulation and sunlight exposure. Pig houses are designed according to local conditions, taking full advantage of seasonal air flow. They are equipped with adjustable ventilation systems like shutters, which help control airflow and temperature inside the house. The roof and windows are designed to optimize sunlight exposure and natural lighting throughout the year.
The second principle involves using the greenhouse effect in winter and the pavilion effect in summer to regulate the pigs’ comfort. In cold months, insulation curtains are lowered, turning the entire pig house into a warm greenhouse, while the fermentation bed itself generates heat, keeping the pigs comfortable. During hot summers, open windows allow for natural breezes and drafts, creating a cool environment for the pigs—similar to how people feel under a shaded tree on a sunny day.
Because of these two principles, the design of the pig house plays a crucial role. The orientation, structure, and type of the building must all be carefully planned to ensure proper ventilation and a comfortable living environment for both pigs and microbes. For example, experts from Jinbao’s ecological fermentation bed suggest:
First, the direction of the pig house should be south-facing. The long axis of the building should be within 15 degrees of due south to maximize sunlight and airflow. This helps maintain a balanced internal climate throughout the year.
Second, the structure of the pigsty needs to have “four windows†– regular windows, skylight windows, and even fan-style windows. Many users of the “bucket-type†or “water bucket-type†fermentation beds often misunderstand the importance of ventilation, leading to poor performance. Experts recommend a minimum height of 3 meters for the pig house to prevent overheating in summer and to ensure good air circulation, which helps remove harmful gases and improves heat dissipation from the pigs. This creates an ideal environment for the beneficial microbes in the fermentation bed.
Third, the type of pig house can vary depending on the local climate—closed, semi-open, open, greenhouse-style, or single-column structures. These designs are combined with rolling shutters to create a flexible, comfortable microclimate for the pigs. The goal is to provide adequate ventilation in summer and insulation in winter, while also considering local water levels—such as ensuring paddy fields are impermeable to prevent moisture issues.
In short, as long as the fermentation bed is built correctly and its principles are properly understood, there’s no need to worry about heat in summer. Even though the core temperature of the fermentation bed can exceed 50°C, the surface remains around 20°C due to heat transfer through the medium. Pigs raised in such an environment enjoy a cool and comfortable setting, similar to how humans feel under a well-ventilated tree. As long as the space is well-ventilated, the summer heat becomes less of a concern. So, if you create a good airflow system, your pigs will stay cool and healthy all year round.
