Abstract: A rearing unit, suitable for piglets, has a heated nest box with openable roof, a pen in communication with the nest box having a perforated floor, a liquid feeding device in the pen having one or more artificial nipples and a solids feed device.The nest box temperature may be thermostatically controlled by a sensor below a perforated floor of the nest box.The unit may be constructed from a slotted framework and boards, the boards being sealed in the slots by an adhesive or inert water-repellant sealant.The unit may house very young piglets up to a weight of from 5 to 8 kg. At that weight, they may then be transferred to a similar unit with a larger nest box until they weigh from 10 to 15 kg.
