What does the research show?
In a large scale study with almost 750 horses, the key findings were:
- 88% of horses were found to be suffering from IAD (higher than in previous studies)
- Horses fed steamed hay from a Haygain hay steamer were 65% less likely to develop IAD
- The impact of IAD on performance was also shown. Poor performance/exercise intolerance was more frequent in horses with fungal particles found in their airway than horses without
- The alternatives to steaming hay did not significantly reduce the risk of IAD. Feeding soaked hay, feeding haylage, or commercial ‘dust free’ hay did not decrease the risk of a positive IAD diagnosis
This study is in line with a preliminary study showing a high prevalence of IAD and the effect of steaming hay with a Haygain hay steamer, but here we have results from a much larger sample and showing even more impact on IAD from steaming than ever before, while also now receiving the endorsement of peer review and publication in the most authoritative journal in its field. The Journal of Internal Veterinary Medicine is the official publication of the American College of Veterinary Internal Medicine, the European College of Veterinary Internal Medicine, the European College of Veterinary Neurology, and the European College of Equine Internal Medicine.
The study also found that steaming hay with a Haygain hay steamer had a protective effect against the development of IAD which suggests it should be used in all horses on an ongoing basis as a preventative measure.
