Two barns for breeding laying hens in South Korea have been equipped with Hotraco automation. The well-known ORION poultry system was installed by our local dealer. Each barn, 80 metres long by 16 metres wide, houses 200,000 animals. The ORION system regulates optimal ventilation in the barn. The air inlets, fans and curtains are perfectly attuned with each other and the ORION system uses silo weighing to regulate and record feed consumption in the barn.
