Coming soon: Heat detection for your 2.5 collars

The breeding window is narrow. Miss it, and you're waiting another 21 days. Every farmer knows the feeling of being in the wrong place at the wrong time.

But what if every heat flagged itself, before the moment passed, across your entire herd? Better data means better timing, and better timing saves you money.

Already on the collar

Your 2.5 collars are already tracking activity, movement, and rumination around the clock. When a cow approaches heat, those patterns shift in a consistent, measurable way. The collar reads those signals and flags them in real time in your Nofence app, no additional sensors, no extra hardware.

Imagine what that can mean for your operation:

• Know when your heifers are cycling. Track first heat so you have a clear picture of where each animal is in her development, and plan your breeding season accordingly.

• Catch silent heats. Some cows cycle without showing visible signs. The collar picks up the behavioral shift even when there's nothing obvious to see.

• Identify open cows early. If an inseminated cow returns to heat, the system flags it early, whether she didn't settle or lost the pregnancy further down the line.

• Know when your cows are ready to rebreed. After calving, the app alerts you when a cow has returned to cycle, so you can act at the right time.

• Get ahead of bull breakdown. Whether a bull isn't serving at all or is covering cows that were meant for AI, the system flags unexpected returns to heat early.

Built on real data

We're currently testing this across markets and real-world conditions to ensure that when a notification reaches your phone, it's as precise as it can be. Early results are looking strong.

Heat detection is coming to all 2.5 collar users later this season. Your collars are about to get a lot more useful.

The cows bring the heat. We just pass on the message.
