Özet
Bu çalışmada, saha şartlarındaki inekderde PGF+PGF GnRH + PGF PRID+ PGF ve deri alli implant + PGF uygulamalarının östrüs senkronizasyonu ve gebelik oranları üzerine etkisi araştinidi. Materyal olarak 125 baş Holstein ırkı inek kullanıldı. Inekler tesadüf örnekleme yöntemi le beş gruba aynidi. Birinci gruba (n= 25) 11 gün arayla iki kez PGF enjekte edildi. İkinci gruba (n=25) 0. gün GnRH ve 7. gün PGF enjeksiyonu yapıldı. Üçüncü gruptaki ineklere (n= 25) 12 gün süreyle PAID ve PRIDin uzaklaştırılmasından bir gün önce PGF uygulandı. Dördüncü gruptaki ineidere (n=25) ise kulak derisi altına yerleştirilen progesteron içeren implantlar 9 gün süreyle tutuldu ve implant uzaklaştırılmadan bir gün önce PGF enjekte edildi. Beşinci gruptakd inekler (n-25) kontrol grubunu oluşturdu. Tohumlamalar 1. grupta son uygulamadan 72 ve 96, II, III ve IV. gruplarda ise 48 ve 72 saat sonra iki kez yapıldı. Kontrol grubundaki inekler (n= 25) ise gelişen östrüslen takiben tohumland. Ineklerde gebelik muayeneleri II. tohumlamalan takiben 60-90 günlerde rektal mu ayene ile gerçekleştirildi. Araştırmada I, II, III, IV ve V. gruplarda sırasıyla östrus oranlan; %100, %96.00, %100, %100 ve %100, gebelik oranian ise; %84.00, %62.50, %84.00, %72.00 ve %52.00 olarak tespit edildi. Östrüs görülme oranları açısından gruplar arasında istatistiki farkdilik saptanmadi (P>0.05). I ve III. Gruplarda elde edilen gebelik oranian V. gruptan yüksekti (P<005). Bununla birlikte, I, II, III ve IV. gruplarda gebelik oranlanı açısından istatistiki farklak saptanmadi (P>0.05). Sonuç olarak, çift doz PGF GnRH + PGF ve implant+ PGF yöntemlerinin PRID+PGF yöntemine göre daha ekonomik, uygulama kolaylığı ve hayvan sahibinin tepkisi açısından değerlendirildiğinde ise çift doz PGF ve GnRH + PGF. enjeksiyonunun daha avantajlı olduğu belirlendi. Bununla birlikte, östrüs gözlemeden sabit zamanlı tohumlamaya imkan vermesi, östrüsü senkronize etmesi ve tohumlama sonrasında yüksek gebelik oranı elde edilmesine olanak sağlamasından dolayı çalışmada kullanılan bütün senkronizasyon yöntemlerinin saha ve işletme şartlarında kullanılabileceği kanısına varıldı.
In this study, the effect of PGF + PGF 20 GnRH+ PGF PRID+PGF and ear implant + PGF app lications on estrus synchronization and fertility in cows in field conditions were investigated. A total of 125 Holstein cows were used as material. Cows were randomly divided in five groups. Two injections of PGF was applied 11 days apart in the first group (n-25) GnRH (day 0) and PGF (7 day later) was injected in the second group (n=25) PRID's were inserted to the anterior vagina of each cow for 12 days and PGF was injected before the day of PRID removal in the third group (n-25) Ear implants were inserted to the ear of each cow subcutaneously for 9 days and PGF was injected before the day of implant removal in the fourth group (n-25). Cows in the group V (n-25) were served as control Artificial in seminations were performed twice at 72-96 hours in the group 1 and 48-72 hours in the groups , ill and IV after the last application. Cows in the control group (n=25) were inseminated with regard to the spontaneous estrous Pregnant cows were determined by rectal paipation between 60-90 days after the second inse ination Estrous and pregnancy rates were %100 %96.00 %100 %100 and %100, %84 00, %62.50 84.00, %72.00 an %52 00, respectively in the groups , TV and V identical estrous rates were found in all groups (P>0.05). Pregnancy stes in the groups i and ill were higher than group V (P<0.05). However pregnancy rates were similar in the groups I, I, il and IV (P005) In conclusion, it was de termined that two injections of PGF GnRH PGF and implant+ PGF, methods are more economic than PAID + PGF, method Looking the more advantegeous about application easiness and agreement of farmer, the injections of PGF 11 days apart and GnRH PGF, is more advantageous However, it was concluded that, all of the synchronization methods used in our study were determined as useful because of allowing fixed-time insemination without estrous detection synchronising estrous and increasing of pregnancy rates in field conditions.
