Straw is the traditional bedding for horses, with wheat straw being the most suitable. Oat and barley straw should not be used for equine bedding. Straw is relatively cheap, fairly easy to dispose of and looks warm, cosy and comfortable.
Straw is derived from grasses and is regarded as a renewable building material since its primary energy input is solar and it can be grown and harvested. Straw bales were first used for building over a century ago. Straw is the springy tubular stalk of grasses like wheat and rice that are high in tensile strength. It is not hay, which is used for feeding livestock and includes the grain head. Straw is composed of cellulose, hemicellulose, lignins and silica.
