While driving, have you ever wondered why there are so many fences to interrupt your soul-satisfying, wide-open-spaces experience? Until recently, that was the only way to keep livestock in their place, so to speak. But today’s wire fencing and posts soon will be augmented with virtual fencing that erases these visual barriers from the landscape.
The concept is simple: You simply equip the animal with a global positioning system (GPS) and a few pieces of electronic hardware. Add a little software that can help send auditory cues where and when they’re needed, with varying levels of intensity, and what do you have? Directional virtual fencing (DVF™).
You can’t let cows linger too long in one area or they might overgraze the available forage. But the vast spaces out West can make it difficult to keep up in person with a herd’s movements.
This new system locates the cows on the range with global positioning and sends auditory signals—such as a human voice—that can be raised or lowered in volume. The commands can range from “gathering songs” sung by cowboys during roundups to sirens that are almost sure to get cows to move or stay away from forbidden areas. This is a more humane method of herd control than using a “one size fits all” approach.
The system is even automated so ranchers can cue their cattle at any time, and track the herd’s movement from a computer.
