Virtual fence (VF) has the potential to change grazing systems by allowing unprecedented impact over livestock distribution. The systems use invisible barriers, established by Global Positioning System (GPS) coordinates, to influence livestock movement with a combination of auditory and electrical cues without a physical fence. VF can be also be complicated and expensive.
This digital guide was created to provide practical, unbiased, vendor-neutral, and realistic information about VF.
Foundations of VF
- Virtual fence (VF) is an emerging precision livestock management tool with multiple interconnected components.
- Examining the costs and benefits of adopting a VF system in a cow-calf operation under different vendors and conditions.
- Virtual fence lines are created in VF software, which requires a digital map of an entire ranch or land management area.
- Equipment needed, strategies for proper fit, and safety when placing virtual fence collars on livestock.
- How livestock recognize and interpret the auditory and electrical cues can limit potential risks for animal health and welfare.
Battery life, collar disposal, strategies for collection in the field, and data organization.
- Special consideration is needed when training livestock, designing fences, managing incentives, and gathering livestock.
- Concise answers to common questions asked by people interested in virtual fence.
