Virtual fencing is an animal-friendly fencing system that enables livestock to be confined or moved without using physical, fixed fences. It uses Global Positioning System (GPS) sensors and wireless technologies to control the movement and location of animals within an area.
The Nofence system consists of collars with transmitters that connect each animal to an app. With the app, you can define the boundaries of your pastures and change these boundaries with the touch of a finger.
Traditional fences rely on the animal's vision. Electric fences work because the animal sees the fence and remembers that touching it causes discomfort. Nofence Grazing Technology instead focuses on the animal's sense of hearing.
Each animal carries a collar. When an animal gets too close to the virtual boundary, the collar will generate a unique tone scale that gradually gets louder. Because the animal interprets this signal as a warning that an electric pulse is about to come, it turns and goes back to the Nofence pasture to switch off the audio and avoid the pulse.
If the animal ignores the audio warning and keeps moving towards the boundary, a half-second, light electric pulse is generated as a last resort to keep them from leaving the grazing zone.
The app also lets you track individual animals using GPS, so you can find them easily.
Virtual fencing with Nofence Grazing Technology makes it easy to manage livestock in a way that maximises resource use as well as satisfying animals' natural behavioural needs.
