Abstract
A one sided creep area farrowing crate fabricated principally from flat material, sheet metal, plastic, wood, etc., has a molded sow pen entrance door with integral rump guard and a longitudinal sheet metal barrier separating the sow pen from the litter creep area while allowing nursing due to the elevation of the sheet metal barrier above the floor surface. Adjacent pairs of farrowing crates may be arranged back to back so as to share a common sow pen wall. With this arrangement a significant floor space reduction is achieved and the mother sow is forced to lie always on the same one side when nursing. Other floor plans may accomplish the same space saving features with this one side creep area, such as the single sow system described herein, or the linear row (side exit) system.
