Methoden der Geburtsüberwachung bei der Stute – eine Übersicht
Methods for parturition monitoring in the mare – an overview
Zusammenfassung
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.
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.
