<p>Bedding for poultry is formed by a litter consisting of a layer of short strips or pieces of absorbent non-toxic paper. The paper, e.g. in the form of newspaper sheets, is first shredded. The shreds are then cut into short strips or small diced pieces which are used as the bedding material. The pieces have a size distribution such that they congeal and form a surface crust or cake at an early stage of use and subsequently break up to form a readily friable material. The layer may take the form of a 'top dressing' covering an existing bedding material to extend its useful life.</p> |
