  • Patent number: 6382135
    Abstract: A pig pen has side walls joined together by end walls to form a substantially rectangular enclosure. An angled divider is pivotable inside the pen, having a first end pivotably arranged on a pivot on one end wall and second end attachable to any one of a plurality of mounts on the opposite end wall. The divider has a first straight portion joined at an angle to a second straight portion, and a lower bar attached with one end adjacent the first end and an opposite end adjacent the second end of the divider. The lower bar is shorter than the total length of the divider and arranged below it, to break the fall of a sow lying down on her side adjacent the divider to provide time for any piglets close to the sow to move away from the sow.
