Virtual fencing for
livestock management
Vence is a virtual fencing livestock management system for cattle. Our tool controls cattle movement, manage grazing, create virtual fences to dictate grazing behavior, and monitor animal location and movement.
Why virtual fencing?

How it works
![Vence basestation icon](https://www.merck-animal-health-usa.com/wp-content/uploads/sites/54/2023/09/Group-2348.png)
Place base station
Base stations are strategically placed on ranch property. One base station
covers 5,000-10,000 acres, depending on terrain.

Place collars
Each CattleRider collar contains a global positioning system (GPS) transceiver that tracks its position and a radio frequency (RF) transceiver.

Set grazing boundaries
Using our HerdManager system, lines can be endlessly redrawn to include or exclude specific areas, which helps with rotational grazing and protecting environmentally sensitive land.

Keep cattle within boundaries
Using sound cues and an animal-safe and humane electric pulse, the collars help cattle learn to avoid stimuli by moving away from the boundary.
Fences at your fingertips
Virtual fencing brings together profit, sustainability and real-time information about your herd — all for considerably less time, effort and money than traditional fencing requires. Hear from Jim Strickland, managing partner at Blackbeard’s Ranch in Mykka City, FL., about how virtual fencing from Vence is transforming his ranch in Florida.

Sustainability
Rotational grazing through Vence mimics the natural movement of cattle across the land to prevent overgrazing, allowing for better long-term management of grass and rangelands, protection over sensitive areas like burn zones and waterfront areas, improved soil health, and more.
