Description

Technical Field

[0001] The utility model relates to the technical field of animal husbandry facilities, in particular to an energy-saving and environmentally friendly high-epidemic livestock and poultry house. Background Art

[0002] At present, the pig farming industry is constantly transforming towards scale and industrialization. Combined with the current requirements of the ecological and environmental protection environment, higher requirements for energy conservation and environmental protection are put forward for the construction of pig houses. Traditional pig houses have poor ventilation effects, and often require a lot of energy for cooling or insulation. At the same time, the large amount of feces and harmful gases produced by pigs are not well handled, causing pollution in the pig houses and endangering the health of pigs and workers. The odorous waste gas emitted affects the living and production environment in the immediate vicinity, causing the local breeding environment to be saturated and potentially creating safety hazards. In addition, in production, the disinfection and epidemic prevention process for pigs in pig farms requires a lot of manpower, but the disinfection effect still cannot meet the needs and cannot be fully disinfected, affecting the normal production of pig farms. Therefore, it is necessary to start from the source and take isolation measures. Utility Model Content
