Housing systems for farrowing sows have changed very little in the past 30 years. At the mid 20th century, two farrowing environments were common the outdoor hut in a pasture or lot, and an indoor farrowing pen. The farrowing pens were in low-cost buildings and thus the cost per square foot of building space was relatively low compared to todays buildings. Farrowing sows indoors has proved to be beneficial for both the producer and the sow and her piglets. However, recent criticism of the traditional farrowing crate has led to increased efforts to find suitable alternatives that still provide maximum production efficiency.
