How Staffing Challenges Affect Modern Pig Farming

Factors such as temperature, air quality, and overall barn stability shape how pigs behave, how efficiently they convert feed, and how vulnerable they are to disease. Modern production systems increasingly rely on real-time environmental monitoring to maintain these conditions, ensuring pigs live in a stable, predictable climate that supports their biological needs.

Why the Barn Matters for Growth

Pigs are highly sensitive to their surroundings. Even small fluctuations in temperature or air quality trigger stress responses which reduce feed intake, slow weight gain, and increase susceptibility to illness. A well-managed environment supports:

• Optimal feed conversion - Pigs use energy for growth instead of fighting heat or cold stress
• Stronger immune function - Stable conditions reduce respiratory challenges and pathogen pressure
• Better welfare - Comfortable pigs are calmer, more active, and show fewer stress-related behaviors
• Lower mortality and medication use - Healthy environments reduce disease outbreaks and treatment needs

These benefits translate directly into improved productivity and profitability for producers.

Key Environmental Factors That Influence Pig Growth

Temperature Stability

Continuous temperature monitoring helps producers maintain the ideal climate for each growth stage - from weaners to finishers.
‍

Air Quality and Ventilation

Air quality is one of the most overlooked drivers of pig health. High levels of ammonia, CO₂, dust, and humidity can damage the respiratory system and increase disease risk.
‍

Humidity Control

Humidity interacts with temperature influencing pig comfort. High humidity makes barns feel warmer, while low humidity increases dust levels in the air.

Noise and Stress Reduction

Environmental stressors - such as sudden noises, drafts, or inconsistent lighting - can disrupt feeding patterns and increase aggression. A calm, predictable environment supports steady growth and reduces injuries.

One of the most important things in farm management, when it comes to profit, is that the data you collect from your farms are accurate and easily withdrawn from the farms. Our climate sensors fit all farm controllers and can be customized for your specific needs. In this way you can collect, share, and compare data from all your farms in one system.

Identify the course of abnormal behaviour

Monitoring the level of ammonia and CO2 can reveal the course of abnormal behaviour at your farm.

Ammonia is a byproduct of animal urine and feces, and high levels of ammonia in the air can irritate the respiratory tract and cause coughing, sneezing, and other respiratory problems in animals. High levels of ammonia can also lead to reduced appetite and weight gain, as well as an increased risk of respiratory infections.

CO2 is a gas produced by the breathing of animals and the decomposition of organic matter. High levels of CO2 in the air can lead to respiratory problems and reduced productivity in animals. It can also be harmful to humans, causing symptoms like headache, dizziness, and fatigue.

Ammonia (NH₃) is one of the most significant environmental and welfare challenges in modern pig production. While it is a natural by-product of livestock systems, excessive ammonia emissions can negatively affect animal health, worker safety, and the surrounding environment. Understanding how ammonia is produced — and how it can be managed — is essential for sustainable, efficient pig farming.

What Is Ammonia and How Is It Produced?

In pig production, ammonia is primarily formed when urea and uric acid in manure and urine are broken down by bacteria. The enzyme urease, naturally present in feces, catalyzes this conversion, releasing ammonia gas into the air.

Key factors influencing ammonia formation include:

• Temperature: Higher temperatures accelerate bacterial activity and volatilization.
• pH: Ammonia release increases when manure pH is above 7.5.
• Ventilation: Inadequate ventilation allows ammonia to accumulate in barns.
• Manure management: Frequent removal and cooling of manure reduce emissions.

Impacts of Ammonia in Pig Housing

1. Animal Health and Welfare

High concentrations of ammonia irritate the pigs’ respiratory tract, leading to:

• Reduced lung function and increased susceptibility to respiratory diseases.
• Lower feed intake and growth rates.
• Increased stress and reduced overall welfare.

Concentrations above 20 ppm are considered harmful to pigs, and levels above 10 ppm are generally discouraged in modern facilities.

2. Worker Health

Ammonia exposure can cause eye and throat irritation, headaches, and long-term respiratory problems in farm workers. Maintaining clean air is therefore not only an animal welfare priority but also a matter of occupational safety.

3. Environmental Impact

Once emitted into the atmosphere, ammonia contributes to acid rain among other things. This has downstream effects on soil, water quality, and climate. The pig industry and other industries are under increasing regulatory pressure to reduce ammonia emissions as part of broader sustainability goals.

4. Production Performance and Efficiency

Ammonia doesn’t just affect welfare — it has a direct impact on productivity. Chronic exposure to elevated ammonia levels has been shown to:

• Reduce average daily gain (ADG) and feed conversion efficiency (FCR).
• Delay the time to reach market weight, increasing feed costs per kilogram of gain.
• Lead to uneven growth within groups, complicating management and marketing.

Studies indicate that pigs exposed to ammonia concentrations above 25–30 ppm may experience growth rate reductions of 5–10%, depending on duration and housing conditions. Maintaining low ammonia levels therefore supports both animal health and economic performance.
