WHAT IS VIRTUAL FENCING?
New to virtual fencing?
Virtual fencing replaces physical barriers with GPS collars that guide cattle using audio cues.
No posts, no wire, no gates. Watch the short video below to see how it works.
The collar design follows the subtle movement of the cow's neck, so when she begins to turn,
the pitch adjusts immediately. These directional cues give precise fence boundaries and
intuitive signals for the animals so they learn quickly and respond consistently.
Animals learn quickly, boundaries hold, and you control everything from an app on your phone.

NEW FEATURES 2026
Monil cattle collars are more than a virtual fence.
Beyond fencing, Monil gives you earlier visibility into what's changing across your herd. A cattle collar that fences, monitors, and manages your herd.
Activity tracking
The first signal. Catch changes early.
In the 2025 season, we implemented the Increased Activity Alert, notifying you when an animal is more active than usual. Increased activity can be a sign of heat, but it can also be triggered by other factors. It was a useful start, and the foundation for something more precise.
Rumination tracking
The second signal. A clearer picture.
Because the collar sits around the cow’s neck, it can also track rumination: the subtle chewing pattern that reflects health and behaviour. When a cow comes into heat, rumination decreases. That second signal is what makes the difference between a best guess and a reliable alert.
Increased activity + Decreased rumination = More reliable heat detection
By combining two signals instead of one, the improved model significantly reduces the risk of false alerts. Giving you confidence to act when it matters.
Improved heat detection:
our strongest model yet.
The improved model combines activity and rumination into a single, more reliable heat alert. When activity rises and rumination drops at the same time, that pattern is a strong indicator your cow is in heat. Fewer false alerts, better timing, and a notification sent directly to the Monil app when it matters most. This is our strongest heat detection model yet, and it becomes a powerful tool for optimising your breeding season.
FROM COLLARS TO COWS
Detection is just the beginning.
The record is what compounds.
Knowing when a cow is in heat is valuable. Knowing how that cow has responded to breeding decisions over two, three, or five seasons – that's where real gains are made. The Monil app connects every alert to an individual animal, so you can build a breeding history that gets more useful over time.
1 Detect
Heat alert received
Activity rises, rumination drops. You get a notification in the app.
2 Decide
Act on the signal
Choose when and how to breed, with confidence in the timing.
3 Note
Log it to the cow
Add a note against that animal: breeding date, method, outcome.
4 Learn
Build her history
Season by season, her record grows. Next year, you start with more.
Track each animal on the map using her ear tag. Add notes at any point in the season: a difficult calving, a missed cycle, a change in behaviour.
“If something’s off, you know about it sooner. That’s where it pays for itself.”
