Poor air quality in livestock housing causes respiratory disease, behavioral impairment, and chronic welfare problems across multiple species.
Animals housed in buildings with poor air quality experience continuous low-grade welfare harm that accumulates over the production cycle. High ammonia concentrations irritate eyes and respiratory tracts, impair immune function, and cause behavioral changes including avoidance of contaminated areas. For poultry, birds cannot escape chronic exposure in enclosed buildings, making air quality management particularly critical. Adequate ventilation must be balanced against temperature requirements, creating design challenges that are well understood but not always adequately resourced. Regular air quality monitoring using ammonia meters provides objective data to drive management improvements.
