    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.

    Abstract: A piglet-protection device for a farrowing pen is equipped with a first side part, with a trough console, which is connected to the first side part, and with a second side part, which is connected to the trough console so as to be pivotable about a pivot axis. By pivoting the second side part, the piglet-protection device can be brought into a piglet-protection position, in which the second side part is arranged substantially parallel to the first side part, and into a movement position, in which the second side part is spread away from the first side part. A first door element and a second door element delimit the piglet-protection device at the rear in the piglet-protection position. The first door element and/or the second door element are arranged in a length-adjustable manner on the first and second side part, respectively.
