Fencing for sows, also called sow barriers or gestation crates, are enclosures designed to provide pregnant pigs with a safe and well-controlled environment. They are widely used in modern pig farming where reproductive cycles need careful management and monitoring. 

The main benefits of these systems include protection from injury, the ability to house each sow separately, and the option to ensure controlled feeding. In this way, every animal receives the nutrition required for its specific stage of pregnancy, which supports both welfare and productivity. 

In addition, fencing helps reduce aggressive behavior and competition within the herd. The enclosures balance space for comfortable movement while limiting excessive activity that could cause health risks. Altogether, sow fencing supports safer conditions and more stable herd management.
