Pig Indoor Air Quality and Respiratory Welfare

Poor air quality in pig buildings causes respiratory disease and welfare compromise, with ammonia, hydrogen sulfide, dust, and inadequate ventilation being key targets for welfare improvement.

Key Facts

Welfare Considerations

Air quality in intensive pig housing is a fundamental welfare issue that directly causes respiratory disease and chronic discomfort. Pigs in high-ammonia environments experience persistent mucous membrane irritation equivalent to humans living in a heavily polluted environment. Respiratory disease is one of the most common causes of mortality and production losses in indoor pig production. Welfare-conscious producers who invest in ventilation design and air quality monitoring reduce disease rates and improve the daily welfare experience of every pig in the building. Simple measurements like ammonia concentration are accessible indicators of indoor air welfare status.
