Siklik ve Siklik olmayan Sütçü İneklerde Ovsynch Protokolüne Verilen Yanıtın Karşılaştırılması

Abstract

Ovsynch protokolü, iki GnRH ve bir PGF2α uygulamasından oluşan ve ovulasyonu sinkronize eden zaman ayarlı suni tohumlama (ST) protokolüdür (GnRH–7gün-PGF2α–56saat–GnRH–18 saat-ST). Bu protokolün avantajı, östrus tespitine gerek kalmadan ST’ye olanak sağlamasıdır. Yapılan çalışmalarda Ovsynch protokolü hem siklik hem de siklik olmayan ineklerde ovulasyonu başarılı bir şekilde sinkronize etmesine rağmen, elde edilen gebelik oranlarında farklılıklar mevcuttur. Bu çalışmanın amaçları; 1) siklik olmayan ineklerde Ovsynch öncesi en büyük follikül çapını belirlemek 2) siklik olmayan ineklerde follikül çapının Ovsynch sonuçları üzerine etkisini saptamak 3) siklik ve siklik olmayan ineklerde Ovsynch protokolüne verilen yanıtı karşılaştırmaktı. İneklerin siklik olup olmadıklarını saptamak amacıyla 7 gün arayla iki kez ovaryumların ultrasonografik muayenesi yapıldı. Çalışma, 181 baş siklik, 69 baş ise siklik olmayan toplam 250 baş inekte gerçekleştirildi. Siklik olmayan ineklerde Ovsynch öncesi en büyük follikül çapı 16-24 mm olan inek oranı (%44.9), 9-15 mm (P
