Livestock manure has been regarded as an important resource containing nutrients such as nitrogen and phosphorus. Over 90% of livestock manure heads to arable land in the form of compost. Particularly, Hanwoo raises on bedding floor which gives comfort and sanitation. However, a main bedding material in Korea is sawdust and have been selected with some conditions of prices, less dust, carbon supply, and so on. This study was carried out to prove alternative bedding materials; e.g., Miscanthus availability. Firstly, the evaluation of comfort was analyzed via checking the resting time of Hanwoo. Secondly, when bedding materials are mixed with manure, biodegradability of Micanthus under composting environment was compared with sawdust. As result of the experiments, Miscanthus gave Hanwoo equal comfort with sawdust and the lowest moisture content in the barn was reported in pelletized Miscanthus. Biodegradability of Miscanthus showed over two fold higher than that of sawdust. Thus, Miscanthus showed enough performance to replace sawdust and could be expected as an economic bedding material over sawdust.
