[Methods for parturition monitoring in the mare – an overview].
Abstract: Various systems are available for birth monitoring in horses, whereby a distinction must be made between methods for more accurate prediction of the date of birth in order to intensify monitoring of the mare in a timely manner as well as methods for detecting individuals that are in labor. Basically, it should be noted that there are almost no studies that compare different methods on the same population of mares. As the time of birth approaches, physiological parameters of mare and fetus change, but their variability is too high to predict the exact parturition time point prospectively. The best method currently available is the detection of a decrease in the pH value and an increase in the calcium concentration of the udder secretions.Continuous camera monitoring is currently the method of choice for the detection of the start of the parturition process. However, the downside of this method is that the recordings have to be evaluated by a human.Recent developments based on the use of artificial intelligence could provide significant improvement. Before these methods are ready for practical use, the combination of camera monitoring and a sensor that is sewn into the vulva and activated during the opening phase of parturition is the safest method. Zur Geburtsüberwachung beim Pferd stehen verschiedene Systeme zur Verfügung. Dabei muss zwischen den Methoden zur genaueren Vorhersage des Geburtstermins, um zeitnah die Überwachung der Stute zu intensivieren, und den Methoden, um Tiere in der Geburt zu detektieren, unterschieden werden. Grundsätzlich ist festzustellen, dass fast keine Untersuchungen, die verschiedene Methoden an einer gleichen Population von Stuten vergleichend testen, vorliegen. Mit Annäherung an den Geburtszeitpunkt verändern sich physiologische Parameter von Stute und Fetus, deren Variabilität jedoch zu hoch ist, um den exakten Geburtszeitpunkt prospektiv vorauszusagen. Die derzeit beste Methode ist der Nachweis des Absinkens des pH-Wertes und der Anstieg der Kalziumkonzentration im Eutersekret.Zur Detektion der Geburt ist zum jetzigen Zeitpunkt die durchgängige Kameraüberwachung die Methode der Wahl. Nachteilig ist, dass die Aufnahmen von einem Menschen bewertet werden müssen. Neuere Entwicklungen durch den Einsatz der künstlichen Intelligenz könnten hier Entlastung schaffen. Bevor diese Methoden praxisreif sind, ist die Kombination von Kameraüberwachung und einem Sensor, der in die Vulva eingenäht und in der Öffnungsphase der Geburt aktiviert wird, die sicherste Methode.

The paper outlines different methodologies employed for birth monitoring in mares. It sheds light on how variations are noted between methods of predicting birth dates for enhanced mare monitoring and those designed to detect laboring individuals. The study concludes with recommending continuous camera monitoring coupled with a sensor sewn into the mare’s vulva as the most effective method until more advanced technologies using artificial intelligence become practical for use.
Context
- The research paper revolves around the mechanisms and systems for birth monitoring in horses. More specifically, it discusses in detail the distinction between methods predicted for estimating the date of birth, which can help in intensifying the mare’s monitoring at the right time, and methods aimed at identifying individuals that are in labor.
Comparative Studies
- The paper bemoans an apparent lack of comparative studies on related themes, noting that very few studies compare various methods within the same mare population. The physiological parameters of mare and fetus change as birth time draws near, but the paper highlights the vast variability in these changes – so vast, in fact, that it’s next to impossible to predict the exact birth time based on them.
Best Available Methods
- According to the study, the current best method involves detecting a decrease in pH value, coupled with an increase in calcium concentration in udder secretions. This combination forms a relative indicator of the approaching birth.
Camera Monitoring
- For detecting the onset of the parturition process, the paper recommends continuous camera monitoring as the best option available today. However, it also highlights a significant drawback of this method, which is the necessity of manual evaluation by humans.
The Role of Artificial Intelligence
- The study proposes that the use of artificial intelligence could dramatically improve camera monitoring. New developments using AI could ideally relieve some of the human-manual evaluation burden and increase effectiveness.
Most Effective Combination
- With AI-based methods still not ready for practical use, the study concludes by recommending a combination of camera monitoring and a sensor sewn into the mare’s vulva. This sensor is activated during the opening phase of parturition, thus providing a reliable method of detection.
