New study shows that feeding Haygain steamed hay reduces the incidence of horses developing IAD by 63%. 


The abstract of this new study by Dr Dauvillier and Dr van Erck-Westergren was presented last month at the Journées de la Recherche Equine in Paris, and parts of which were previously presented at the American College of Veterinary Internal Medicine in June 2016.


Steaming hay in the Haygain hay steamer drastically improved the hygiene quality of whole bales of hay. The microbial contamination was reduced to zero for fungi and yeasts and by 98.84% for bacteria.

Spring steam! 


As Spring starts to get closer horses can spend more time outside grazing but be aware of the sugar rich grass, which is low in fibre.


The only nutrient lost after a 50 minute cycle in the Haygain HG1000 was WSC (sugar), which was a small but significant reduction.

Steaming reduces the RAO-affected horse’s response to hay, coinciding with a reduction in viable fungal content of hay.

Soaking hay for 9 hours followed by steaming for 50 minutes is the most effective method for reducing WSC and microbial contamination.

A 50 minute steam in the Haygain HG1000 was effective at reducing respirable particles in all hays, whether slightly dusty or very contaminated.

The HG600 steamer is the most effective treatment for improving the hygienic quality of the hay, while soaking was found to vastly increase bacteria6th.


European Workshop for Equine Nutrition, 2012


This study found that the HG 600 is significantly more effective at reducing microbes in hay compared with home-made steamers and soaking.


Proceedings of the European Equine Health and Nutrition Congress, 2013


This study underlined that horses preferred to eat steamed hay compared to haylage and dry hay.


Proceedings of British Society of Animal Science Conference, 2013


Steamed hay was preferred over dry and soaked hay: once tasted, Haygain hay was always the first to be consumed.  


Advances in Animal Biosciences, 2012


Steaming hay in the HG600 significantly reduces microbial growth, even after 4 days of being left open.
