I was first introduced to Haygain when we acquired a unit in our equine hospital for cases that have been diagnosed with respiratory issues. We have used it for foals with severe Rhodococcus equi pneumonia, to aid in reducing the amount of inhaled allergens when they eat hay. We have also steamed bedding (ie: straw) for the same reduction of potential inhaled allergens. For our colic surgeries that are not eating well, we have used the Haygain steamed hay to entice those horses to consume more roughage. The fresh aroma after the hay has been steamed appears to increase many horses’ appetite post-surgery. I have first-hand experience with this product because not only do I use the Haygain unit at my hospital, but for my own personal dressage and racehorses as well.
