Cattle and sheep stanchions are installed between the livestock living area and feeding passage. When cattle and sheep eat feed, the self-locking device of the stanchion can fix their heads automatically, enabling each livestock to feed independently and stably, preventing feed scrambling and trampling accidents. We provide different sizes and specifications corresponding to calves, growing cattle & sheep and adult livestock according to their growth stages. Customized sizes are also available based on customers' breeding house dimensions and livestock breeds.
