New Research Shows That Most Racehorses Have Inflammatory Airway Disease

Biopsies of the lung tissue of 95 Thoroughbred, Standardbred and Quarter Horse racehorses that had raced or trained before their deaths showed that the majority of the horses had inflammatory airway disease (IAD).

Performed by Canada’s Ontario Veterinary College, the lung tissue was examined under a microscope and the number of inflammatory cells found were quantified. The results show that IAD is much more prevalent than previously believed; most of the study horses had airway changes ranging from mild to severe.

None of the horses used in the sample had shown any signs that they were experiencing respiratory issues in their last three races, when IAD is usually seen.

Possible causes of IAD include atmospheric pollutants, persistent viral infections, deep inhalation of dust and recurrent pulmonary stress. Findings from the study will lead to a better understanding of IAD, a healthier equine athlete and a more-competitive racing industry.
