The pig house is the living environment of the pigs. It is of great significance to improve the pig house environment and improve the economic growth of the pigs. Generally speaking, for large-scale farms, they will actively promote the regulation and control of three indicators of a good pig house, namely, temperature, humidity and air cleanliness. In recent years, it has been popularized and quickly promoted. The golden treasure dry spreader bed, which is favored by friends for breeding, is not only littered at a constant temperature of about 20 degrees throughout the year, but has become a pig-breeding air-conditioned room, and is also uniquely endowed with air cleanliness in pig houses. The advantages are significant. Specific performance in the following areas: 1. The construction design of the fermentation bed is more scientific and rational. It emphasizes ventilation and ensures air safety and cleanliness. Fermentation bed pens are required to be built in a high-pitched and dry place. This will ensure that the pig farm has sufficient ambient light and good air circulation. The pig houses generally face the south and take the east-west direction. The major difference in the design of the Jinbao dry-sauce fermentation bed housing compared with cement ground housing is the importance of ventilation in the coordination of heat preservation and ventilation. In order to ensure ventilation, the doors and windows of the fermentation bed house were expanded as much as possible, and the air vents (ie, ground windows) at the root of the sunroof and the wall were added. This not only ensures the air flow over the pens, but also increases the multi-directional air convection including the bottom of the pens, which can fully remove the exhaust gas produced by the swine's breath and other harmful gases, ensuring the safety and cleanliness of the air. 2. The pig feed density has been scientifically planned to ensure healthy growth space. The pig rearing density is negatively correlated with the air cleanliness of the pig house. Pigs occupy not only the size of the ground, but also the depth of the upper space, and the upper space ensures the existence of air distribution and cushioning. Under normal circumstances, the area (m2) of fermented bed occupied by each pig in the Jinbao dry-type fermentation bed is not lower than the following standards: 0.5-1.0 for piglets, 1.5-2.0 for medium pigs, 2.0-2.5 for large pigs, and Pigs account for 6.0 to 8.0 per head, which guarantees sufficient space for pigs to grow up and also facilitates air cleanliness and disease prevention and control. 3. There are micro-organisms in the pig house hygiene, and harmful gases are difficult to generate. Most of the pungent smelly gas in the pig house is caused by the pig's excrement not being cleaned in time, such as ammonia, hydrogen sulfide, carbon dioxide and other toxic and harmful gases. The ginba dry fermentation bed can quickly decompose pig manure into nutrients that can be used through the fermentation of the functional microbes contained in the litter. At the same time, the construction of the fermentation bed also emphasizes ventilation, adding windows and skylights. In the pig house, more air flows are formed to fully remove the harmful gases generated in the pig house, ensuring a clean and fresh environment for the pigs. The regulation of temperature and humidity in the pig house is relatively simple, and the air cleanliness often becomes a difficulty for the breeding friends. From the site selection, design and construction of the golden treasure dry fermentation bed, the cleanliness of the air is fully taken into account, coupled with the efficient decomposition of the functional microbes on the excreta, to ensure the cleanliness of the pig house to the maximum extent and to ensure the The pig's healthy growth environment.
