Zusammenfassung
Gegenstand und Ziel: Beschreibung der verschiedenen hormonellen Fruchtbarkeitsprogramme bei Kühen. Material und Methode: Literaturübersicht. Ergebnisse: Es werden die physiologischen Grundlagen und die Durchführung von Hormonprogrammen auf Basis von Prostaglandinen und des kombinierten Einsatzes von Prostaglandinen und GnRH-Analoga dargestellt. Dabei erfolgt eine Beschreibung von Vor- und Nachteilen der verschiedenen Programme. Ausgehend vom Ovsynch-Programm werden dessen Modifikationen Cosynch, Select Synch, Heatsynch und Ultrasynch dargestellt. Klinische Relevanz: Die Darlegung der verschiedenen Fruchtbarkeitsprogramme soll dem Tierarzt helfen, das optimale Vorgehen für die von ihm betreuten Betriebe zu gestalten.
Summary
Introduction: Description of different hormonal reproductive programs in cows. Material and methods: Literature review. Results: The underlying physiological principles and the implementation of hormonal programs based on the use of prostaglandins and combinations of prostaglandins with GnRH analogues are presented. In this context, the advantages and disadvantages of each program are explained. Based on the Ovsynch program, its modifications, Cosynch, Select Synch, Heatsynch and Ultrasynch, are described. Clinical relevance: The description of the different reproductive programs is designed to assist the attending veterinarian in choosing the optimum strategy for each farm.
