Research and publications

Interesting summary article from Kentucky Equine Research of a recent research paper on Inflammatory Airway Disease (IAD) in asymptomatic horses (showing no clinical signs). The research group based out of Murdoch University in Perth, Australia found that 95% of the horses in the study were found to have IAD via bronchoalveolar lavage fluid (BALF) cytology. The instance of IAD was much greater than researchers anticipated, given that none of the horses showed any sign of the disease.

There are several other papers to support this high prevalence of undiagnosed inflammatory airway disease.

Petri dish: before and after hay steaming

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.

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

Proceedings of the Annual ACVIM Conference, 2012

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 bacteria

6th 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
