“…A literature review revealed dystocia in mixed mare populations, with rates of 10.1% (McCue & Ferris, 2012) and 11.2% (Ginther & Williams, 1996) Surveys conducted at stud farms indicated dystocia rates ranging from 2% to 13% across these breeds (Ellerbrock & Wehrend, 2023a).…”

“…This does not apply to the cases of the present study as obstetric assistance was provided on‐site by a specialized veterinarian. Regardless of the type of treatment, prolonged dystocias are also associated with an unfavourable prognosis for the mare's survival (Ellerbrock & Wehrend, 2023b). In Freeman et al.…”

“…(1996) observed a 4.5% dystocia rate in draught horse crosses. Surveys conducted at stud farms indicated dystocia rates ranging from 2% to 13% across these breeds (Ellerbrock & Wehrend, 2023a). This study, in turn, reveals closely aligned dystocia frequencies at 9.7% (20/207) across the groups.…”

“…Therefore, timely recognition of potential complications is necessary to prevent the fatal consequences of dystocia (Frazer et al., 1999; McCue & Ferris, 2012). A recent literature search revealed that the frequency of dystocia, its causes, and consequences in horses was typically determined retrospectively in previous studies (Ellerbrock & Wehrend, 2023a, 2023b). At present, there is a lack of data offering insights into how often horses, having encountered pregnancy disorders or parturition complications in a previous pregnancy, subsequently develop dystocia.…”

Dystocia typically presents a life‐threatening condition for both the mare and the foal. This prospective long‐term study aimed to ascertain whether mares with prior pregnancy disorders or a history of dystocia were at a higher risk of experiencing subsequent dystocia in comparison to those without such medical antecedents. To achieve this goal, the authors analysed 207 parturitions and 164 mares over a 10‐year period. Of these, 57 were associated with pregnancy disorders or prior dystocia (Group 1), while 150 parturitions followed uneventful pregnancies in mares that had not yet experienced dystocia (Group 2). Mares in Group 1 were significantly more likely to develop dystocia than those in Group 2 (p = .0180; odds ratio = 2.98). Foetal causes of dystocia were more prevalent than maternal causes (p < .0389). Maternal mortality stood at 0.5%, and neonatal mortality reached 1.9%. The results demonstrate that mares are at significantly higher risk of developing dystocia after experiencing pregnancy disorders or parturition complications during previous pregnancies, emphasizing the need for systematic birth monitoring.

ZusammenfassungDie Geburt des Pferdes ist dadurch gekennzeichnet, dass es bei Verzögerungen sehr schnell zum Tod des Fohlens kommt. Daher ist eine Geburtsüberwachung bzw. die möglichst schnelle Erkennung einer Dystokie von großer Bedeutung. Dazu ist es wichtig, zwischen Verhalten, das mit einer physiologischen Geburt und mit einer Schwergeburt assoziiert ist, zu unterscheiden. Ziel dieser Veröffentlichung ist es daher, anhand einer Literaturübersicht das physiologische Verhalten von Stuten in der Geburt darzustellen. Das Verhalten der Stuten in der Öffnungsphase der Geburt ist sehr individuell. Generell ist es durch eine Erhöhung der Bewegungsaktivität gekennzeichnet. In dieser Phase sind 13 verschiedene Verhaltensweisen beschrieben (z. B. Hinlegen und Aufstehen, Einstellen der Futteraufnahme, lokales Schwitzen, häufiger Kot- und Harnabsatz). In der Austreibungsphase und Nachgeburtsphase zeigen Stuten ein einheitlicheres Verhaltensmuster. Über 95% der Stuten gebären in Seitenlage. Nach der Expulsion des Fetus bleiben Stuten in der Regel noch einige Minuten liegen. Unmittelbar nach dem Aufstehen beginnen die Stuten intensiv mit dem Fohlen Kontakt aufzunehmen. Die Expulsion der Nachgeburt erfolgt meist im Stehen. Für die Praxis ist festzuhalten, dass die Erkennung der Geburt in der Öffnungsphase der Geburt aufgrund der individuellen Verhaltensweisen der Stuten schwierig ist.

Investigating the suitability of a transponder-based birth monitoring system attached to the vulva of a mare

Background and Aim: In horse breeding, birth monitoring is an important factor in minimizing losses during parturition. Although different birth monitoring systems are available for this purpose, the current literature lacks systematic suitability analyses. This study aimed to address this gap in the literature. In order to achieve this, we examined a large number of foaling mares to assess the suitability of a transponder-based birth monitoring system attached to the vulva. Materials and Methods: Seventy warmblood mares were observed during foaling, and 86 foals were born during the foaling seasons of 2021 and 2022. Video surveillance in the foaling stable provided video recordings of births. This allowed the opportunity to assess the birth monitoring system’s reporting accuracy. The exact times and reasons for each alarm were documented and the proportions of correctly detected births, false alarms, and unrecognized births were calculated. Results: Overall, 96.5% of foalings were correctly detected using the birth monitoring system, with a sensitivity rate of 96% and a specificity rate of 91%. False alarms were primarily caused when a mare rubbed her tail against the stable walls. Conclusion: These data suggest that the tested transponder is well suited for monitoring the birth of mares. However, it is recommended that this method should be used in combination with other birth monitoring methods because not all births were detected correctly. Keywords: birth alarm, mare, parturition, transponder system.
