Adapts to either end of the production unit. Crowding capacity is limited. May require using the sick pen when added to existing floors. Pens of 60 hogs can be sorted conveniently. Less building materials are required than for some others.
System is compact.
Swine are reluctant to cross the service alley and enter crowd. Location is south of the feeding floor. This system should handle groups of 60 hogs. Producers anticipate an advantage by heading hogs toward the vacated feeding pen. No positive crowd to force swine into the sorting alley.
