In den letzten Jahren wurde wiederholt \u00fcber den\n erfolgreichen Einsatz von equinen Choriongonadotropin (eCG) in diesem\n Zusammenhang berichtet, andere Studie konnten keine positiven Effekte einer\n eCG-Gabe auf die puerperale Involution von K\u00fchen nachweisen. Aufgrund\n der differenten Ergebnisse in der Literatur war es Ziel dieser Feldstudie, zu\n \u00fcberpr\u00fcfen, ob sich eine Applikation von eCG am 10. Tag post\n partum (p.p.) positiv auf die Uterusinvolution, die Ovaraktivit\u00e4t und\n die Fruchtbarkeitskennzahlen bei Fleckvieh-K\u00fchen auswirkt.<\/jats:p>\n Material und Methoden In 9 milchviehhaltenden Betrieben wurden 203\n Fleckviehk\u00fche per Los in 3 Gruppen eingeteilt: Die Tiere der Gruppe 1\n erhielten 500 I.E. eCG, der Gruppe 2 50\u2009\u00b5g Gonadorelin und die\n Tiere der Gruppe 3 250\u2009mg Butafosfan und 125\u2009\u00b5g\n Cyanocobalamin (Kontrollgruppe). Die Behandlung erfolgte jeweils am 10. Tag p.p.\n Die Tiere wurden am 10., 25. und 42. Tag p.p. klinisch und ultrasonografisch\n untersucht sowie die Zeit bis zur erneuten Besamung und Tr\u00e4chtigkeit\n erfasst. Der Gruppenvergleich hinsichtlich der erfassten Parameter erfolgte\n zuerst ohne Beachtung von St\u00f6rfaktoren durch eine Varianzanalyse. Im\n zweiten Schritt erfolgte die Ber\u00fccksichtigung potenzieller\n St\u00f6rvariablen (Laktation, Milchleistung der ersten 100 Laktationstage,\n Ver\u00e4nderung der R\u00fcckenfettdicke, Auftreten von\n Nachgeburtsverhalten und Schwere der Geburtshilfe) sowie der Kombination der\n zuf\u00e4lligen Faktoren \u201eBetrieb\u201c und \u201eEinzeltier\n innerhalb des Betriebes\u201c.<\/jats:p>\n Ergebnisse Die Applikation des eCG hatte keinen signifikanten Effekt auf\n die Uterusinvolution, sehr wohl aber auf die Involution der Zervix. In der\n Gruppe der K\u00fche mit eCG-Applikation konnte am 25. Tag p.p. signifikant\n h\u00e4ufiger eine Ovarialzyste nachgewiesen werden (p=0,04). Dieser\n Unterschied bestand am 42. Tag p.p. nicht mehr. Weder Rast- noch\n G\u00fcstzeit wurden durch die Verabreichung von eCG signifikant\n verk\u00fcrzt. Die Laktationszahl zeigte einen signifikanten Einfluss auf die\n Uterusinvolution. Die F\u00e4rsen wiesen eine schnellere Involution bis zum\n 42. Tag p.p. als die K\u00fche auf.<\/jats:p>\n Schlussfolgerungen Die Gabe von eCG am 10. Tag p.p. an\n Fleckviehk\u00fche zeigt keinen ausreichend positiven Effekt auf die\n Involution des Uterus.<\/jats:p>\n Klinische Relevanz Auf den Einsatz von eCG im Fr\u00fchpuerpium zur\n F\u00f6rderung der Fruchtbarkeit bei der Kuh sollte verzichtet werden.<\/jats:p>","DOI":"10.1055\/a-2142-4111","type":"journal-article","created":{"date-parts":[[2023,10,11]],"date-time":"2023-10-11T22:32:50Z","timestamp":1697063570000},"page":"211-217","source":"Crossref","is-referenced-by-count":0,"title":["Einfluss
