Pig Air Quality Welfare Monitoring

Air quality in pig buildings significantly affects respiratory health and welfare, with ammonia, hydrogen sulphide, and dust as primary concerns.

Key Facts

Ammonia concentrations above 25 ppm cause respiratory irritation and welfare compromise in pigs
Hydrogen sulphide from slurry handling causes acute toxicity and can be rapidly fatal
Dust in pig buildings carries pathogens and irritates respiratory airways
Regulatory limits exist for ammonia in pig housing but are rarely monitored in practice
Ventilation system maintenance and slurry management are primary air quality control measures

Welfare Considerations

Pigs living in poor air quality environments experience chronic respiratory irritation that reduces feed intake, compromises immunity, and causes long-term welfare harm. Routine air quality monitoring would significantly improve welfare outcomes.

What You Can Do

Advocate for mandatory air quality monitoring in pig housing as part of farm welfare inspection
Support farms investing in improved ventilation systems and slurry management
Choose pork from farms with documented air quality monitoring protocols
