  • Patent number: 4541359
    Abstract: A litter covering for placement over litter used in poultry houses. The litter covering comprises a sheet of paper which is gradually degradable into litter within 28 days. The paper is treated with ferrous sulphate hepta hydrate for ammonia control and is sufficiently water absorbent to facilitate moisture control in the poultry house. The paper has an indented design for cushioning and providing good footing for young chicks. The litter covering serves both as a physical barrier between the poultry and the litter and as a barrier of masking ammonia produced from used litter.
