Why 80% of These Horses May Have Asthma

Horses, with their large lung and respiratory capacities, are very susceptible to respiratory disease. In fact, it’s estimated that 80% of racehorses have asthma, according to research by Laurent L. Couëtil, DVM, Ph.D., director of Purdue University's Equine Sports Medicine Center, and colleagues. The Purdue researchers have described two types of equine asthma. One is more severe and typically affects older horses, leading to mucus production, coughing and difficulty breathing. The other type is milder and is often seen in younger racehorses. Although it may not affect quality of life like the more severe form, it interferes with athletic performance. The researchers are looking into the disease in horses and have revealed that while genetics can play a role, asthma in horses may be largely due to environmental factors, including dust and mold exposure from hay.  Read more....
