From Paper Notes to Phone Alerts: A Slovenian Family’s Experience With a Cow Monitoring Collar

For Urban Hajšek and his family in Slovenia, noticing that a cow was in heat used to mean making a note on paper and calling an insemination service. Sometimes, by the time they saw the signs and arranged a visit, they were already running late.

The family checked their animals as part of everyday farm work. But a walk through the barn could only tell them so much about what had happened between visits, particularly when signs were subtle or appeared at night.

That uncertainty was one reason they introduced MooCollar Bree. All 45 cows on the family farm now wear MooCollar devices. After around two years of use, Urban describes having a better view of individual animals and their heat histories, with less guesswork between routine checks.

Urban is also affiliated with HAJ-TECH, a Sveaverken partner in Slovenia. Here, he shares how the system has become part of life on his family’s own dairy farm.

Why the Family Chose Wearable Cow Collars

Urban wanted technology to make working with animals easier. Unlike a person, a cow cannot explain what is bothering her. The family had to work out what was happening from what they could see, and the clearest signs did not always appear when someone was there to notice them.

Before MooCollar Bree, they had not used another electronic monitoring system. Their own observations, together with handwritten records, were what they had to work with.

Introducing wearable cow collars gave them something else to refer to. Between barn visits, Urban could open the app on his phone and review information about an animal, rather than relying entirely on the last time he had seen her.

The family still knew and watched their cows. They now had a more complete record to bring to those observations.

Using Cow Collars for Heat Detection Between Routine Checks

Understanding What Manual Observation Could Miss

Timing had been a recurring difficulty. First, someone needed to notice that a cow was in heat. Then the family needed to contact the insemination service and arrange a visit. Seeing the signs late left less time for everything that followed.

Urban also described heat events with less obvious signs, or signs that appeared during the night. Even with regular checks, those could be missed.

Once the family began using the collars, they identified more heat events than they had noticed before. Urban’s understanding was that some of those events had been happening all along; the family simply had not seen them.

That changed what they knew between visits to the barn. There was more to work with than the signs visible at the moment someone happened to be watching.

Reviewing Cow Monitoring Collar Alerts Alongside Heat History

With current alerts and earlier heat records in one app, Urban could look back at what had happened before. A recorded event no longer meant searching through handwritten notes to find the previous one.

He described reviewing the timing information in the app when planning insemination. For his family, using cow collars for heat detection made those decisions better informed by an animal’s history.

There was still room for what he saw himself. If Urban observed a heat event, he could record it. If an alert did not match his assessment, he could add that information too. The records and the family’s observations became part of the same routine.

Turning Cattle Collar Sensor Information Into Practical Decisions

A Change in Rumination Prompted a Closer Look

One of the family’s early experiences involved a cow they knew as an animal that spent a substantial amount of time ruminating. When her rumination activity decreased, the change stood out.

The information prompted the family to investigate and respond to a health issue. What mattered was the difference from that particular cow’s usual pattern: there was a reason to go and take a closer look.

The system had not provided a diagnosis on its own. It had drawn the family’s attention to an animal that needed checking.

Keeping the Farmer’s Observations in the Process

Other situations called for Urban to compare an alert with what he could see on the farm. He described recording a heat event he had observed, or marking an alert that did not match his assessment. He found those steps straightforward.

His experience gives a practical meaning to cattle collar sensor information. It needs to be easy to review, check against the animal and add to when the farmer has something to record.

For Urban, being able to do that was part of making the information useful in daily work.

Bringing MooCollar Bree Into the Farm Routine

Getting started involved both setting up the equipment and fitting the collars to the cows.

Urban described getting the gateway running within a few hours, with internet access available where it was installed. Handling the animals took longer. He estimated half a day to a full day to fit the collars, depending on how easily the cows could be handled.

He then paired the devices with the app by scanning a QR code or using NFC.

The family also has cows that graze outside. Urban reported that connectivity had worked well in their setting, allowing the system to remain part of their routine when those animals were out grazing.

Those timings and connection experiences belong to this farm. They describe how the family got started, rather than a fixed installation time or coverage result for every location.

What Changed for the Family?

The family reports more pregnancies and lower insemination costs since adopting MooCollar Bree. The way those changes unfolded was more involved than simply installing the collars.

At first, identifying more heat events meant calling the insemination service more often. Later, Urban’s father completed the qualification to carry out insemination himself. Both the information available to the family and the way they organised insemination had changed.

Their account does not provide a measured pregnancy-rate improvement, and it does not isolate a cost reduction attributable to the collars alone. The family’s cost experience includes that change in how insemination was carried out.

What Urban describes most clearly is the difference in everyday confidence. He can look up records on his phone, review events the family might previously have missed, and use that information when deciding which animal deserves closer attention.

The family still observes the herd and makes the decisions. There is now more information to bring to each check, and less uncertainty about what may have happened since the last one.

As Urban puts it:

“Above all, they have given us peace of mind about our animals’ health and fertility.”

For his family, the move from paper notes to phone alerts has become part of how they care for their 45 cows, one observation and one decision at a time.
