How Barn Air Quality Affects Your Horse’s Respiratory Health
Poor air quality can increase the risk of respiratory issues like equine asthma. Dust, mold, fungal spores, and ammonia can irritate a horse’s lungs, making clean air especially important for horses that spend much of their time indoors. Good ventilation helps reduce these airborne irritants and supports healthier breathing in barns, trailers, and indoor arenas.
Key Findings Referenced
- Ammonia accumulation is associated with poor ventilation and wet bedding.
- Mechanical ventilation reduces ammonia concentrations.
- Dust, mold, spores, and ammonia contribute to respiratory inflammation.
