Probed horse bedding is a haulm based product which 'behaves' just as wood shavings when working with it. Because it is not wood based it tends not clog together when wet. It can be used light or deep littered, with or without rubber mats.Probed horse bedding has been treated with anti fungal and anti bacterial agents and has been tested by the Irish Equine Centre so is safe to use with horses. It is treated with eucalyptus to promote easy breathing. Because it has a very bitter taste your horses will not eat it as they can sometimes do with straw. Probed horse bedding has gone through three separate dust extraction processes, which makes it one of the best products in the marketplace. Each bale is approximately 140 litres which means that you should only need four to five bales to make a new bed.
