Inflammatory Airway Disease

“Horses live and work in environmental conditions that promote chronic respiratory inflammation. The prevalence of lower airway diseases is largely underestimated because it is not always accompanied by obvious clinical signs. Medications treat the symptoms but not its initial cause, which often lies in the environment. Changes in environmental management are essential to bring long term relief. 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!”Emmanuelle van Erck-Westergren, DVM, PhD Dip.

“I love using Haygain Steamed Hay because it helps improve my horses’ respiratory conditions and stopped them from coughing,” “With Haygain’s help, I can make sure the hay wherever I go is never dusty and it’s bacteria free, so my horses don’t have any issues during competitions.”Jessica Springsteen, Team USA

You may not have noticed your horse coughing, but even the slightest of coughs could be a sign of Inflammatory Airway Disease. What are the implications and what can be done?

Coughing could be a sign of Inflammatory Airway Disease (IAD)

A recent study* found 88% of horses were suffering from Inflammatory Airway Disease (IAD). IAD can affect horses of all ages and clinical signs include poor performance (exercise intolerance and poor recovery), nasal discharge and occasional coughing at rest and/or during exercise. Clinical signs are often subtle and horses have normal breathing at rest, so IAD can go unnoticed while affecting the horses ability to perform.Common treatments prescribed by veterinarians include bronchodilators and corticosteroids but the key to both prevention and management of IAD is reducing exposure to airborne dust.

Steam, don't Soak

The IAD study found that IAD was closely linked to the dust found in hay, and that simply by steaming hay with a Haygain hay steamer the incidence of IAD reduced by 65%.

Other benefits of steaming your hay include:

  • Increased palatability - several studies show how horses prefer steamed hay over dry and soaked hay

  • Hydration - steamed hay provides a useful additional source of water in high temperatures

  • Retains nutritional value – unlike soaking, steaming retains the nutritional goodness of the hay including protein and minerals with just a small, variable loss of water soluble carbohydrate

“[We] take the smaller unit away to competitions all over Europe, which we find essential. The horses have been free from coughs and nasal discharge, they are healthy and performing well”

What the veterinarians say

“We have used Haygain for foals with severe Rhodococcusequi pneumonia to aid in reducing the amount of inhaled allergens when they eat hay. We have also steamed bedding (ie: straw, not shavings) for the same reduction of potential inhaled allergens. For our colic surgeries that are not eating well, we have used Haygain to entice those horses to consume more roughage. The fresh aroma after the hay has been steamed appears to increase many horse's appetite postsurgery. I have first-hand experience with this product because not only do I use Haygain at my hospital, but for my own personal dressage and racehorses as well.”
