    Abstract: A farrowing pen for a group farrowing pen arranged in the farrowing pen includes a piglet protection device having a first side part, a second side part, which is arranged substantially parallel to the first side part and is spaced apart therefrom in such a manner that the first and the second side part laterally delimit a receiving space for a sow, and a rear-side door element movable between a closed position and an open position, which, in the closed position, delimits the receiving space on the rear side and, in the open position, opens up a rear-side access to the receiving space. The farrowing pen designed such that the sow can automatically enter and/or leave the receiving space of the piglet-protection device, with the rear-side door element being transferred by the sow into the closed position if the sow has entered the piglet-protection device.
