Heaves, also known as Severe Equine Asthma, is more common than you think and we are here to help

Studies show that 68 to 80% of pleasure horses and racehorses suffer from mild to moderate equine asthma (Couetil et al., 2020). And up to 17% of horses —based on research in cool climates—battle the more severe form of the disease (Hotchkiss JW, Reid SWJ, Christley RM. Equine Veterinary Journal., 2007).These horses cough, have exercise intolerance, increased respiratory efforts at rest, and nasal discharge, and can become lethargic and uncomfortable. But scientists widely suspect that many more horses are affected by mild equine asthma but have gone undiagnosed due to their less obvious clinical signs, like poor performance (Dauvillier, Woort and van Erck‐Westergren, 2018).

There’s no cure for this debilitating disease affecting the horse’s general health, welfare, and performance over the horse’s entire lifetime. Medications can help, but the number one management strategy is prevention, keeping horses free of the triggers found in their environment—and especially their hay. And that’s where Haygain excels. Scientific research has shown, study after study, overwhelming evidence for Haygain Hay Steamers’ ability to nearly eliminate the pathogens in hay and thus to reduce the incidence of Inflammatory Airway Disease (IAD) and other respiratory diseases in horses.

Scientific research has shown, study after study, overwhelming evidence for Haygain Hay Steamers’ ability to nearly eliminate the pathogens in hay and thus to reduce the incidence of Inflammatory Airway Disease (IAD) and other respiratory diseases in horses.

Horses breathe in nearly 5 million particles of dust and other triggers with every breath while eating hay, making this the biggest contributing factors to heaves.

Hay starts out as wet grass that gets bailed up before it’s completely dry, trapping humidity that promotes the growth of microscopic quantities of mold that are often invisible to the naked eye—even in high-quality hay dried in good conditions. This leads to the production of harmful spores and dust, the key causes of respiratory diseases like heaves.

Dry hay contains typically of 932 thousand Airborne Respirable Dust (ARD) particles per liter of air. Given that horses inhale 5 liters of air with each breath, this means they’re inhaling about 4.6 million ARD particles every time they fill their lungs with their noses hovering over their hay (Journal of Equine Veterinary Science Moore-Colyer et al., 2015).

Haygain Hay Steamers offer the only effective, science-backed solution to the management of heaves


Haygain Steamers provide a sustainable way to improve respiratory health and keep your horse breathing comfortably

Corticosteroids and bronchodilators provide immediate relief for severe clinical symptoms. But because of their long-term side effects, these drugs can only be used for brief periods.

Haygain steamers, however, offer a lifelong solution, due to the overwhelming evidence for their effectiveness in reducing Inflammatory Airway Disease (IAD) and other respiratory diseases in horses. In fact, no other tested method of feeding hay has been found to be as effective (Dauvillier, Woort and van Erck‐Westergren, 2018).

Soaking: the treacherous “solution”

Soaking hay may dampen respirable particles by 90%, making horses less likely to breathe them in while eating. However, soaking does not kill these living organisms, which continue to thrive and rapidly multiply in this now extra-humid environment, with bacteria alone increasing by 150% within 10 minutes of soaking. While the horses might not be breathing in all those bacteria and other proliferating particles, they’re eating them. Once in the digestive system, these pathogenic bacteria, mold, and fungal spores can still elicit allergic reactions and other inflammatory responses.

Soaking also makes the hay less tasty to horses, with studies showing that they prefer the taste of dry hay. Steaming hay in a Haygain steamer, however, makes the forage actually taste better, with horses consistently choosing Haygain-steamed hay in taste tests.

Soaking also causes important nutrients to seep out of the hay, getting wasted in the hundreds of liters of runoff water which actually turns into a toxic soup that’s nine times more polluting that raw sewage.

By contrast, Haygain steamers use only 3.5 liters of water per steam cycle, much of which gets absorbed into the hay or released into the air, resulting in a residue of only about a teacup full of condensation water that drains through a hole at the bottom of the hay chest.

Experts agree that the single-most important treatment for heaves is improving the environment by reducing exposure to dust and molds. It’s the only long-term solution, as clinical signs always return after medication is discontinued if the horse remains in a dusty, moldy environment (www.ksvhc.org, n.d.).

The Best Way to Reduce Allergies: Reduce the Allergens

Sensitivity to one allergen often increases your horse’s sensitivity to other allergens, compounding the challenges for horses with heaves. Haygain’s ability to significantly reduce allergens in hay helps prevent this never-ending spiral of hypersensitivity. 

The Power of Prevention: Horses fed Haygain-steamed hay are 65% less likely to develop IAD

Haygain Hay Steamers don’t just help horses that are battling heaves, but every single horse in your barn. That’s because when you feed virtually dust-free forage, you’re reducing the overall quantity of airborne dust in the whole stable and actually reducing the chances of healthy horses ever developing a respiratory disease. Results from a large-scale study have shown that Haygain-steamed hay cut the risk of mild equine asthma (IAD) by 65% (Journal of Veterinary Internal Medicine Dauvillier, Woort and van Erck‐Westergren, 2018).


The Power of Prevention: Horses fed Haygain-steamed hay are 65% less likely to develop IAD

Haygain Hay Steamers can help all the horses in your barn, not only those affected by heaves. Feeding virtually dust-free forage to your heaves horse helps reduce the overall quantity of airborne dust in the whole stable.

For healthy horses, Haygain is a powerful tool for keeping them that way. Results from a large-scale study demonstrate that feeding Haygain Steamed Hay reduces risk of Inflammatory Airway Disease (mild equine asthma) occurrence by 65% (Journal of Veterinary Internal Medicine Dauvillier, Woort and van Erck‐Westergren, 2018).

"Haygain hay steamers are a simple, fool proof solution to improve our horse’s respiratory health. I recommend it for my patients and those owners who have adopted it really see the daily benefit it brings to their horses and would not revert to normal hay; and the horses love it!” 

Wren Burnley DVM

"I never want to go back to soaking hay again; as an asthmatic and an athlete myself, I cannot stick my nose in a regular bale of hay, but I can in a bale that has come out of the Haygain machine!"
