Horse Respiratory Health - Advanced Management

Advanced management of equine respiratory conditions including equine asthma, IAD, and EIPH, covering environmental and medical approaches.

Key Facts

Equine asthma (formerly heaves/RAO) affects up to 14% of horses in temperate regions
Dust and mould in hay and bedding are the primary environmental triggers for equine asthma flares
Soaking or steaming hay reduces respirable dust exposure by 70-90%, the most important environmental intervention
Corticosteroid inhaler therapy using a spacer device enables targeted lung delivery with reduced systemic effects
Exercise-induced pulmonary haemorrhage (EIPH) affects up to 75% of racehorses during high-intensity exercise

Welfare Considerations

Respiratory disease causes distress, exercise intolerance, and reduced quality of life in affected horses. Many cases are managed inadequately because signs are subtle or attributed to poor fitness. Environmental management - particularly dust reduction - is both the most important and most underimplemented intervention. Horses managed in high-dust environments without hay treatment suffer preventable chronic respiratory compromise.

What You Can Do

Switch to steamed or haylage forage for horses with recurrent respiratory signs
Improve stable ventilation with minimum 4 air changes per hour in horse housing
Use low-dust bedding alternatives including paper, cardboard, or dust-extracted shavings
Discuss inhaled corticosteroid or bronchodilator therapy with your vet for moderate to severe cases
Avoid exercising horses with active respiratory flares, particularly in dusty arenas
