Monitoring Foaling: How to Choose the Right Foaling Alarm
Every spring, the same tension returns to the breeding farms: the mare is nearing term, and foaling almost always starts at night, often within minutes. A normal foaling is quick — but when complications arise, every minute counts. Yet it’s impossible to stay awake for weeks on end. That’s where the foaling alarm comes in: a tool that alerts you at the right moment so you can be present when needed. Here we explain how these systems work, how to choose one, and especially how to monitor properly — the alarm being just one link in the chain.
How a foaling alarm works
The principle is simple and based on an old observation by breeders: at the time of foaling, the mare adopts a characteristic posture — lateral recumbency, lying flat on her side — accompanied by typical movements (rolling, agitation). The sensor aims to detect this behavior.
Depending on the systems, detection relies on one or more indicators:
- The lying on the side posture: an inclination/position sensor, attached to the surcingle, reacts when the mare remains flat (lateral recumbency) for longer than a certain time.
- The associated movements (rolling, agitation) that accompany this posture, depending on the technology used.
- For your information: other manufacturers offer vulvar probes based on a different principle. This is a technology not covered by the Birth Alarm range presented here, which operates with a position/inclination sensor worn on the surcingle.
When triggered, the transmitting unit alerts the breeder: phone call, SMS, or signal to a receiver box, depending on the model. You are alerted wherever you are and can reach the stall.
Which system for which breeding
The right choice mainly depends on the number of mares, your setup (network, stall), and your budget. Here are some guidelines to help you decide — to be refined with us according to your situation.
| Profile | What matters | Our approach |
|---|---|---|
| Private breeder, 1 to 2 mares | Simplicity, controlled cost, alert by phone call (SIM card) | Birth Alarm Lite 2.0 — entry-level model, reliable and economical |
| Breeding attached to an autonomous radio system, without relying on the mobile network | Reliability of a battery-powered transmitter + fixed receiver, robustness | Birth Alarm Classique 433MHz (with surcingle) — reliable radio system |
| Demanding breeding / enhanced monitoring, multiple recipients | Versatility, advanced features, app management | Birth Alarm Premium Plus — high-end version, the most versatile |
In all cases, two questions to ask beforehand. First, how does the alert reach you? The Birth Alarm Lite 2.0 and Premium Plus use the mobile network (SIM card) — so check that your stall is properly covered; the Birth Alarm Classique 433MHz works via radio between a battery-powered transmitter and a fixed receiver, without relying on the mobile network. Next, who receives the alert, and what backup is in place if the first person doesn’t respond? A well-designed system includes a human plan B.
Good monitoring practices
The alarm only works well if the surrounding monitoring is solid. Our recommendations:
- Anticipate the signs. Watch the development of the udder, the “wax” on the teats, and ligament relaxation. The alarm complements this observation; it does not replace it.
- Prepare the stall. Clean, bedded, disinfected, without dangerous corners, with a water point and lighting quickly accessible.
- Test the system before the due date. Install and check the alarm several days before the expected date: alert reception, battery, sensor or surcingle adjustment.
- Keep useful numbers handy. Vet informed of the approximate date, number displayed, and a way to reach them at night.
- Prepare a foaling kit. A few essentials to gather in advance: clean disposable gloves, disinfectant for the foal’s navel (such as chlorhexidine or iodine solution), a clean rope or tie, and the vet’s number noted and reachable at night. Also, know how to recognize what is normal and what is not.
False alarms: this is normal. Expect “rest” alerts in the days before the due date: a mare lying flat on her side just to sleep can trigger the sensor. This is not a system fault — better an unnecessary disturbance than a missed foaling. Your first movements will quickly teach you to distinguish rest from the true start of foaling.

Frequently Asked Questions
Does a foaling alarm detect all foalings?
No. These systems detect the typical behavior of a foaling mare (lying on her side, associated movements), but no device guarantees 100% detection. A mare can foal standing or very quickly. The alarm greatly reduces the risk of missing the moment, without eliminating it: your vigilance remains essential.
Does the alarm replace my presence at night?
No. It allows you to rest while being alerted at the right time, but it assists monitoring, it does not replace it. You must be able to reach the stall quickly, and the vet must be reachable in case of complications.
Is it normal to receive false alerts?
Yes, it is to be expected. In the days before the due date, a mare lying flat on her side to sleep can trigger the sensor. These "rest" alerts are normal: better an unnecessary disturbance than a missed foaling. With experience, you will quickly distinguish rest from the true start of foaling.
What is the range or battery life of these systems?
These features vary depending on the model and your setup (network, distance, stall). We prefer not to give figures that could mislead you: refer to the manufacturer's manual and always test the system at home before the due date.
How to choose between the different models?
Depending on your setup and the level of comfort desired. The Birth Alarm Lite 2.0, a reliable and economical entry-level model, is suitable for an individual with one or two mares (alert via call through SIM card). The Birth Alarm Classique 433MHz is a reliable radio system (battery-powered transmitter + fixed receiver) that does not depend on the mobile network. The Birth Alarm Premium Plus, a high-end version, is the most versatile thanks to its advanced functions and app management. If in doubt, contact us.
When to install and test the alarm?
Several days before the expected foaling date. Check the alert reception, battery, and the adjustment of the sensor or surcingle. A cold test prevents unpleasant surprises during the night.
