Studies have shown , a lot of kinds of timber because contain the harmful to animal material without suitable for making bedding and padding. So the work of research and develop new type animal used as test bedding and padding very meaningful. Chinese Academy of Agricultural Sciences Harbin veterinarian scientific research staffs of research institute in order to grow on perennial herb broad leaf cattail of wetland, the Northeast of China, as the research object, Study about resource, distributed, biological characteristic, physical characteristic, polluting situation and toxicity, etc. Proved the stem or leaf of cattail to be abundant and cheap resource, and get easy, the quality is soft , absorb water, suck strong ammonia, include no harmful toxicity material to animal, It is no harmful effects to grop, development and breed of rodents, It is a kind of better bedding and padding material.展开更多
