Important Environmental and Ventilation Tips for Small Swine Producers: Part 1

By Casey Zangaro

Investing in an optimal indoor environment for your swine herd is not just a task; it is a crucial step that significantly enhances their health and productivity. A well-designed facility with adequate space per pig ensures comfort and reduces stress, leading to a healthier and more productive herd. Configuring pens with solid dividers can help minimize aggressive behavior and facilitate easier management.

Configuring pens with solid dividers can help minimize aggressive behavior and facilitate easier management.

Ventilation systems are not just a feature; they are the cornerstone of maintaining air quality in your swine facility. While natural ventilation through windows and vents is necessary, mechanical ventilation systems with fans significantly enhance air exchange for closed facilities. Proper airflow management is crucial, such as directing fresh air away from pig areas to minimize drafts. Maintaining comfortable temperatures between 60 degrees Fahrenheit and 75F (15 degrees Centegrade to 24C) is vital, and fire-safe heater systems or heat lamps for piglets should be used during colder months to ensure warmth. These measures ensure the health of your herd and provide you with the peace of mind that comes from knowing your pigs are well-cared for.

An understanding of the best humidity control is a growing science. Research, as a consequence of understanding COVID-19 transmission, suggests that low humidity (below 50%) and high aerosol dust and pollutants help viruses to remain stable in the air, in other words, increasing the risk to your pigs. Perhaps more important to animal health is the number of times that fresh air enters the room and polluted air is exhausted. Air speeds (600 to 800 feet per minute) bring in fresh air and exhaust old air (air changes), will reduce the spread of airborne disease by lowering the concentration of dust particles and animal gas emissions (ammonia and carbon dioxide), as well as lowering temperatures in the summer.

Ventilation fans improve air changes, yet they can lose efficiency if allowed to build up with dust. Regular cleaning routines and ammonia detectors can help maintain safe air quality, while effective manure management practices can minimize odors.

Do not leave your pigs in the dark. Lighting is another crucial aspect; incorporating natural light through windows or skylights can improve pig well-being, while energy-efficient artificial lighting systems can help maintain consistent lighting schedules. Regular maintenance, including routine inspections of ventilation systems and pest control measures, is essential to ensure the effectiveness of the facility's environment. By staying on top of these tasks, you can feel confident in your proactive approach to maintaining a healthy environment for your pigs.

Implementing biosecurity measures is critical for preventing disease spread within the herd. Limiting access to the facility and establishing cleaning protocols for personnel and equipment can significantly enhance biosecurity. Designating isolation areas for sick or new animals further protects the herd's health, giving you the confidence that you are doing everything possible to keep your pigs healthy.

By adhering to these guidelines, small swine producers can take control and create a healthier indoor environment that significantly enhances the well-being and productivity of their herd. Your role as a producer is crucial in this process and by following these tips, you can feel empowered to impact pig health positively.
