This research indicates that steaming reduces the RAO-affected horse’s response to hay which coincides with a reduction in viable fungal content of hay.

A second and separate palatability trial further demonstrating that horses prefer to eat steamed hay compared with haylage and dry hay.

This study found the HAYGAIN HG600 to be the most effective treatment for improving the hygienic quality of the hay while soaking was found to vastly increase bacteria.

An increase of 64% TVC (bacteria) and 75% mould concentrations was found in haylage open and left for 4 days. Steaming haylage in the HG600 significantly reduced microbial growth, even after 4 days of being left open.

A comparison of different steaming techniques was done in this experiment which showed that steaming in a specifically designed hay steamer (HG 600) was significantly more effective at reducing microbes in hay compared with home-made steamers and soaking.

Soaking hay for 9 hours followed by steaming for 50 minutes in the HG steamer was the most effective method for reducing both WSC and microbial contamination in hay.

Forage in the stable – techniques for reducing the respirable challenge and microbial content in hay.

Steaming and disinfecting straw reduces RP and microbial content and will allow the horse to benefit from the behavioural advantages of straw without compromising respiratory health.

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

Investigation into the effect of different treatments on Hay and Haylage on forage pH levels, in relation to EGUS in the horse.

Soaking hay for 9 hours followed by steaming for 50 minutes in the HG steamer was the most effective method for reducing both WSC and microbial contamination in hay.
