NoFence is a virtual fencing system with the aim of finding a solution to the problems with keeping animals within a predefined when physical fences not are an option. The system consists of a collar based on GPS technology. When an animal wearing an activated collar crosses a predefined border, a sound signal will be given. If the animals then turns and walks back into the grazing area, the sound signal will stop. If the animal instead continue to walk over the border, the collar will give the animals an electric correction through two electrodes placed on the neck of the animal. Bioforsk Økologisk was hired to perform an independent evaluation about the welfare situation among animals on NoFence pastures. The aim with the trials 2012 was hence to do a first evaluation if/how NoFence affects sheep welfare and how quick the animals can learn the system.
