New intelligent pig house, realizing fresh air filtration, independent ventilation and sterilization and deodorization

Qingdao Puhui: Leading the future of breeding and creating a new benchmark for all-round intelligent pig houses

The new intelligent pig house innovatively developed by Qingdao Puhui marks a solid step forward in the direction of high-tech, refined and welfare-oriented modern animal husbandry. The pig house system is not a simple equipment upgrade, but a comprehensive solution that deeply integrates cutting-edge technologies such as the Internet of Things, automatic control, and bio-environmental engineering. It aims to create a nearly ideal growth environment for pigs and fundamentally improve breeding efficiency and biosafety.

1. Core environmental control: precise guarantee of healthy air

* Fresh air filtration and independent ventilation: The system abandons the traditional model of relying on natural ventilation and adopts an active air treatment system. The external air first passes through multi-stage high-efficiency filtration (such as primary + medium efficiency or even high-efficiency filters) to effectively block the invasion of dust, pollen, pathogenic microorganisms (such as PEDV, PRRSV, etc.) and harmful aerosols, greatly reducing the risk of respiratory diseases. The interior adopts a partitioned independent ventilation design. According to the growth stage of pigs (such as suckling piglets and fattening pigs) and the location requirements of the pens, the air intake, wind speed and flow direction of each area are accurately controlled to avoid airflow dead corners and ensure uniform and fresh air.
* Dynamic environment intelligent control: Based on the established "pig comfort standard model" (covering key parameter thresholds such as temperature, humidity, wind speed, ammonia concentration, and carbon dioxide concentration), various sensors throughout the house (temperature and humidity, gas, pressure, light, etc.) collect environmental data in real time. The intelligent environmental control system is like the "brain" of the pig house. It analyzes the data in real time through complex algorithms and automatically links and controls the equipment:
* Accurate temperature control: Combined with floor heating, water heating, fan wet curtains, variable frequency fans, and even local heating lamps/insulation boards, accurate temperature control is achieved all year round, especially to meet the differentiated needs of piglets for high temperature and fattening pigs for suitable temperature.
* Humidity balance: Automatically adjust the ventilation volume and dehumidification/humidification equipment to prevent diseases caused by excessive humidity or dust increase caused by too low humidity.
* Harmful gas removal: Real-time monitoring of ammonia (NH₃), hydrogen sulfide (H₂S), carbon dioxide (CO₂) and other concentrations. Once exceeded, the system immediately increases the ventilation efficiency and may link special deodorization and sterilization equipment (such as UV photolysis, plasma, biological filtration, etc.) to efficiently decompose harmful gas molecules, significantly improve the air quality in the house, and protect the respiratory health of pigs and the living environment.

2. IoT-driven full-process real-time monitoring: transparent management and risk warning
IoT technology is the neural network of this smart pig house. By deploying sensors and smart devices at key nodes, a full-dimensional monitoring network covering "environment-pigs-equipment" is built:
* Visualization of environmental parameters: All environmental data (temperature, humidity, gas concentration, light, wind speed, negative pressure, etc.) are transmitted to the cloud platform or local control room in real time. Managers can view them at any time through computers or mobile phone APPs, and historical data can be traced and analyzed.
* Pig status perception (indirect): Combined with video monitoring, sound analysis (such as cough recognition), feeding and drinking water monitoring equipment (smart feed troughs, water meters), and the possible integration of automatic weight measurement and behavior analysis cameras in the future, the system can indirectly evaluate the activity, health status and growth trend of the pig herd, and promptly detect abnormal individual or group problems.
* Equipment operation monitoring and early warning: The operating status and energy consumption of key equipment such as fans, water pumps, heaters, and controllers are online in real time. The system can predict equipment failures (such as abnormal fan speed and reduced heater efficiency) and issue maintenance warnings in advance to minimize environmental fluctuations and production losses caused by equipment failures.

3. The core goal of health and welfare: building a biosafety barrier
The ultimate goal of all technologies is to create a healthy, comfortable, and low-stress growth environment for pigs:
* Disease prevention and control upgrade: Efficient air filtration and continuous sterilization and deodorization (such as regular or on-demand triggered UV-C and ozone disinfection) reduce the input and spread of pathogens from the source, significantly reduce the incidence of epidemics, and reduce dependence on antibiotics.
* Minimization of stressors: A constant comfortable environment (avoiding excessive cold, overheating, and drafts), fresh air, and appropriate lighting effectively reduce the environmental stress response of pigs, which is essential for improving immunity, promoting feeding and digestion and absorption, and improving meat quality.
* Support for precision nutrition and management: A stable environment is the basis for pigs to achieve optimal growth performance. Combined with a precision feeding system (integrable), pigs can only obtain nutrition that matches their stage needs and achieve better feed conversion rate (FCR) and daily weight gain (ADG) in a comfortable environment.

4. Comprehensive benefits: efficiency, quality, and sustainability
Qingdao Puhui's smart pig house solution not only improves animal welfare and health, but also brings significant economic and social benefits:
* Improved production efficiency: Reduce mortality, increase growth rate, improve feed conversion rate, and directly increase breeding income.
* Leap in management efficiency: Remote monitoring, automatic alarm, and data-driven decision-making greatly reduce manual labor intensity and management difficulty, and improve management accuracy.
* Product quality assurance: Healthier pigs and less medication lay a solid foundation for the production of safe and high-quality pork products.
* Environmental sustainability: Effectively control odor emissions and improve the farm and surrounding environment; accurate resource (energy, water, feed) utilization is in line with the development direction of green and low-carbon farming.
* Data asset accumulation: The massive environmental and production data accumulated over a long period of operation provide valuable scientific basis for optimizing farming models, conducting genetic breeding evaluations, and improving overall farming levels.

Conclusion:
Qingdao Puhui's new intelligent pig house goes beyond the scope of traditional farming facilities and is a modern agricultural technology crystallization that integrates environmental engineering, intelligent control, the Internet of Things and big data applications. It creates a highly controllable, transparent, healthy and comfortable growth space, which not only effectively guarantees the health and welfare of the pig herd, but also promotes the accelerated transformation of the farming industry to an efficient, intelligent, green and sustainable future, and sets a new benchmark for the construction of modern and intelligent pig farms.
