This year's LAMMA will offer an opportunity for farmers to speak to animal collar specialists Nofence on their four years of use on UK farms. The system employs a blend of GPS, cellular communication, audio signals, and solar power.

Through the Nofence smartphone app, virtual fence perimeters can be established and monitored, taking into account animal behaviour. This allows livestock to graze within specified perimeters without the need for physical fencing.

"When an animal crosses a Nofence boundary, the collars emit an audio cue to alert it to the boundary perimeter. If the animal doesn't turn around upon hearing the predictable audio cue, the collars issue an electric pulse. The collars also track animal locations, providing data on detailed grazing patterns and animal movement.

They are also equipped with solar panels to ensure long-lasting battery life throughout the grazing season," says John Smout, Sales Manager for Nofence. "With Nofence, we train the animals to listen for their fence boundary. So, we are still relying on the animal’s senses to stay within the grazing parameter, but it is hearing rather than visual.

"The technology has proved to excel in a diverse set of applications. Our trial work and customer experience have shown that cattle can be grazed on intensive rotational and strip systems while successfully maintaining tight covers."

Nofence has also been a popular tool for upland producers looking to maximize land usage and better manage grazing without investing in physical fencing infrastructure.
