We have been using the Haygain hay steamers to steam oat hay and lucerne for the 160 racehorses in our yard on a daily basis. In addition, we have also used it for horses with allergies and have steamed their straw bedding. We are very happy with the product. The oat hay, lucerne and bedding are less dusty which has a positive impact on their respiratory health and well being. The horses also seem to enjoy the steamed roughage and we would recommend the Haygain as an excellent addition to a professional yard.
