Horse Respiratory Disease and Air Quality Welfare

Respiratory disease is among the most common health and welfare problems in stabled horses. Understanding the relationship between stable environment and respiratory health helps owners take protective action.

Key Facts

Equine asthma affects up to 14% of horses in temperate climates
Dust and mould spores from hay and bedding are the primary triggers for equine respiratory disease
Horses evolved for continuous outdoor movement and are poorly adapted to enclosed stabling
Good stable ventilation significantly reduces airborne dust and respiratory disease incidence
Soaking or steaming hay reduces respirable dust by up to 95% compared to dry hay
Horses with chronic respiratory disease show reduced exercise tolerance and quality of life

Welfare Considerations

Stable air quality directly affects equine respiratory health and welfare. Horses in dusty, poorly ventilated stables breathe air containing concentrations of particulates that would be considered unsafe for humans. This causes chronic inflammation and respiratory compromise that affects quality of life and performance. Simple management changes including ventilation improvement, low-dust bedding, and hay treatment can dramatically reduce disease burden and improve welfare.

What You Can Do

Ensure your horse stable has good natural ventilation without draughts
Switch to low-dust bedding materials like rubber matting, shavings, or paper
Soak or steam hay for horses with respiratory sensitivity
Keep affected horses outdoors as much as possible
Work with your vet to monitor respiratory health and adjust management accordingly
