In a farrowing pen which includes a pit and over the pit a first floor section on which the sow can stand and lie and two further floor sections on each side of the first floor section for receiving piglets of the sow and confining walls for locating the sow on the first floor section there is provided an apparatus for lifting the sow away from the piglets to prevent crushing. The apparatus includes a base carries above the pit either on legs or on a cradle and a gas bag lift mechanism carried on the base above the manure and arranged to raise a plate carrying two parallel rails with the first floor section thereon. An air valve extends through the flooring and is operated by pressure from contact with the sow for actuating the controlling the flow of the air. The rate of lifting is faster than the rate of lowering. Extendible legs around the base support and guide the floor on the bag.
