How Heat Siecker Works


When a cow is in heat, and other cows mount her, the patch senses the pressure


That individual cow’s data is sent from the HeatSiecker Gateway Antenna to your phone.


Then you can prioritize insemination based on real-time data and detect the perfect breeding window.

Happy Customers


Yackley Ranches

“We used the HeatSiecker program on a group of virgin heifers. We put the patches on in May and only had one fall off out of the 65 when we pulled the bulls out in mid-August. Like any new system, there is a learning curve. However, with the HeatSiecker app, the data received is easy to interpret. They system is quick and easy to install and very economical.”


Bar A Cattle
Nocona, TX

“We used HeatSiecker on 30 receipt cows and had excellent results. We did it in December and the days were short so not only did the system work extremely well for picking up heats but it saved us many hours of checking cows in the dark. Knowing exactly when the cows started standing was valuable info when we put eggs in and catching the repeats two weeks later worked great. Our cows have had the patches on for almost 60 days and we have not lost a patch. I’m a believer in HeatSiecker.”

“The HeatSiecker system has revolutionized our timed insemination of our donor battery as well as maximized the use of our receipt herd and allowed us to use and find more cows and accurately implant eggs at the appropriate times.”


Pope Farms Embryo Transfer
Ravenna, NE

“By using HeatSiecker we have been able to do a much better job of detecting heats on donor cows in between flushes. This allows us to do a better job of scheduling their next flush and work with tiger natural schedule. It especially helps in the winter when it gets dark earlier. It’s amazing how many mounts are recorded at night when we are not watching. Not having to spend as much time watching the cows means more time with family. I can be sitting at a basketball game in town and receive an alert on my phone informing me that I need to breed a cow early the next morning.”

Precision Agriculture is a phrase that gets used a lot in agriculture right now. With HeatSiecker, you can truly have great precision in your breeding program. We run a very aggressive AI and ET program. HeatSiecker makes heat detection simple and accurate!”


Reproductive Services LLC
Lincoln, NE

“The HeatSiecker program will be a game changer for many operations. Timing of heats and the uncertainty play a big roll in the success in most situations. Proper heat detection is time consuming, and with everyone’s busy lifestyle, HeatSiecker can save even the smallest cattleman many hours that can be spent elsewhere. In our operation I would not be without it.”


DJC Genetics
Phillips, NE

“We had a chance to use HeatSiecker patches. They proved to be a very good tool to aid us in heatchecking. I liked that we could tell the onset of standing heat. This made it easier to group the recipes as well as the cows we AI. I can see this to be very beneficial when breeding donors and when using sexed semen where timing is more critical. We will be using HeatSiecker again.”
