Summary

Objective: The effects of various parturition controlling measures in sows on the relevant parameters for parturition were investigated. Material and methods: A total of 1975 study animals were divided into five groups: control group: A (n = 710); trial groups: B (n = 719), C (n = 180), D (n = 175), E (n = 191). The control group (A) included sows that spontaneously farrowed until day 114 of gestation. The remaining sows were administered a PGF2α-analogue (175 µg cloprostenol) on day 114. All sows that farrowed within 24 hours after prostaglandin-medication were summarised in trial group B. Dams that did not farrow until day 115 were either administered oxytocin (20 IU i. m., group C) or carbetocin in two different doses (70 µg, group D or 35 µg, group E). The sows were monitored during the peripartal period over 24 hours. Results: 83.8% of the farrowings were without any complications. The percentage of dystocia varied between the individual groups. Given a complication-free farrowing the expulsion stage began 13.0 hours (group B), 2.4 hours (group C), 1.6 hours (group D) and 1.4 hours (group E) after medication. The expulsion interval of the farrowing of two piglets decreased from 21.1 minutes with spontaneous farrowings (group A) to 18.6 minutes (group E) as a result of the administration of 35 µg carbetocin. The rate of stillborn piglets as well as the incidence of puerperal disorders and the losses of the suckling piglets also gradually, partly even significantly (p 0.05) decreased from group A to E. Conclusion and clinical relevance: The results of this study show that the use of the long-acting oxytocin carbetocin has advantages compared to oxytocin (e. g. shortened duration of birth, reduction of stillbirths). The tested dosages of carbetocin (35 µg or 70 µg) proved to be equally effective. Administration of the lower dose is recommended, since this reduces use of the active ingredient.

Zusammenfassung

Gegenstand und Ziel: Überprüft wurden die Auswirkungen verschiedener geburtssteuernder Maßnahmen beim Schwein auf partusrele vante Parameter. Material und Methoden: Insgesamt 1975 Sauen wurden in fünf Gruppen aufgeteilt: Kontrollgruppe: A (n = 710); Versuchsgruppen: B (n = 719), C (n = 180), D (n = 175), E (n = 191). Die Kontrollgruppe (A) umfasste Sauen, die bis zum 114. Tag der Gravi dität spontan in die Geburt kamen. Die verbliebenen Sauen erhielten am 114. Tag ein PGF2α-Analogon (175 µg Cloprostenol). In Versuchsgruppe B wurden alle Sauen zusammengefasst, deren Geburt innerhalb von 24 Stunden nach der Prostaglandin-Medikation erfolgte. Sauen, die bis zum 115. Tag nicht mit der Geburt begonnen hatten, erhielten alternierend entweder Oxytocin (20 IE, Gruppe C) oder Car betocin in unterschiedlicher Dosierung (70 µg, Gruppe D bzw. 35 µg, Gruppe E). Die Sauen wurden im peripartalen Zeitraum über 24 Stun den überwacht. Ergebnisse: 83,8% der Geburten verliefen komplikationslos. Der An teil an Dystokien differierte zwischen den Gruppen. Bei komplikationsfreiem Geburtsverlauf erfolgte der Beginn der Austreibungsphase 13,0 (Gruppe B), 2,4 (Gruppe C), 1,6 (Gruppe D) und 1,4 Stunden post medicationem (Gruppe E). Das Intervall zwischen der Expulsation zweier Ferkel sank von 21,1 Minu ten bei spontanen Geburten (Gruppe A) auf 18,6 Minuten unter Wirkung von 35 µg Carbetocin (Gruppe E). Auch die Totgeburtenrate sowie die Inzidenz postpartaler Störungen und die Saugferkelverluste nahmen stufenweise, teilweise signifikant (p 0.05) von Gruppe A zu Gruppe E ab. Schlussfolgerung und kli nische Relevanz: Die Untersuchungen zeigen, dass die Verwendung des Langzeitoxytocins Carbetocin Vorteile gegenüber Oxytocin aufweist (unter anderem Verkürzung der Geburtsdauer, Verminderung der Totgeburtenrate). Die getesteten Carbetocindosierungen (35 µg und 70 µg) erwiesen sich als gleich wirksam. Um den Wirkstoffverbrauch zu reduzieren, sollte die niedrigere Dosierung Anwendung finden.
