In small operations the weaning area may be a part of the farrowing barn. In large operations one or several specialised weaning rooms let the producer maintain the warmer environment preferred by the weaning pig.
Weaning pigs must be kept especially clean to maintain good health. The traditional way to do this was to use ample bedding and clean the pens frequently. Now, pens with slotted perforated or mesh floors are used to keep pigs clean enough at this stage.
