  • Patent number: 6435135
    Abstract: A wood based product comprises condensed natural wood fibres. The wood fibres have bulk density of about 20 lbs/ft3 or greater at moisture content of about 15% by weight or less, and each particle of the wood fibres has a particle size of less than about {fraction (3/16)} inch. By using such condensed wood fibres, the wood based product is capable of functioning as physical bedding for poultry that can absorb moisture and ammonia for a complete production cycle of commercial poultry operations.
