This intelligent separation system is specifically designed to meet the needs, activities and demands of high density, high performing production sows. Sows using this system have total freedom to develop their natural behaviours, favouring the tranquillity of this dynamic grouping system. The separation system identifies the chip carried by each sow and, according to the data collected, lets the sow go to the next station or make them repeat according to the data characteristics. In this way the sows stay organised, and given enough space to eat in turn maintains a peace of mind during gestation.
