A thermally insulated, forced or naturally ventilated house divided into pens containing groups of pigs. May have:
Fully slatted floor. Pens have fully slatted floors with no physical separation between lying, feeding and dunging areas. Slurry is collected in a channel or pit beneath the floor that may connect to a central channel for emptying.
Partially slatted floor. Similar to above except the floor is divided into a slatted area (for dunging), with a slurry channel or pit beneath it, and a solid, non-slatted (for feeding and resting) area. Some straw is sometimes provided where there is a solid floors and a smaller slatted area. The solid floor may have a slight slope so that slurry and straw move towards the slats (straw flow system).
Solid floor. Straw is spread over the floor to provide bedding or in smaller amounts for animal welfare or may be washed down with water if no bedding is used.
