PLAZMA PROGESTERON DÜZEYLERİNE GÖRE PGF2α ile ÖSTRÜS SENKRONİZASYONU ve SABİT ZAMANLI TOHUMLAMANIN GEBELİK ORANI ÜZERİNE ETKİSİ

Year 1998, Volume: 14 Issue: 2, 77 - 83, 01.06.1998

Abstract

Bu çalışma, inelderde plazma progesıeron düzeylerine göre PGF2a ile östrus senkronizasyonu ve sabit zamanlı tohumlamanın etkinli{Jinin araştırılması amacryfa yapılmıştır. Araşıırma, 3 • 5 yaşlı toplam 34 baş isviçre Esmer ırkı inek üzerinde gerçekleştirildi. fneklerden östrus sildusunun evresine bakılmaksızın 10 gün arayla 3 kez kan ôme{Ji alındı. Her ömeklemede plazma progesteron düzeyleri yüksek (:2: 0.5 ng i ml) olan ineklere PGF2o. (O. 150 mg D • CIop­r05lenol) uygulanarak 72 ve 96. saatlerde sabit zamanlı tohumlama yapıldı. Gebelik Ianısı tohumlamadan sonra 21, günde plazma progesıeron düzeyterine ve 60 gün sonra rektal palpasyorı bulgularına göre yapıldı. Araştırmada kul­lanılan ineiderin ilk ömeklemeleri sonunda 23'Onde progesteron dOzeyi yüksek bulundu ve yapılan senkrorıizasyon ve tohumlama sonunda lS'sl gebe kaldı. ikinci örneklemeye kalan 11 baş inek'ten S'inde progesteron düzeyi yOksek bulundu ve yapılan tohumlama sonunda 4'0 gebe kaldı. Üçüncü ömeklemeye kalan 3 baş inekte ise progesıeron düzeyi yine düşük bulundu. Toplam olarak 31 inek progesteron düzeyine göre PGF2a ile senkronize edildi ve yapılan sabiı zamanlı tohumlama sorıunda 20 ("lo 66.6)'si gebe kaldı. Sonuç olarak, plazma progesteron düzeyterine göre lu­teal aktivite belirlenen ineiderin PGF2o. ile senkronizasyonu ve sabit zamanlı tohumlanmaları sonunda sağlanan ge­belik oranı memnuniyet verici düzeyde bulunıııuştur. Ayrıca, luteal aktiviteye sahip olmayan ineklem teşhisi ve bu ineklere yapılacak PGF2o. enjeksiyonunun elimine edilmesi açısından da faydalı bulundu

The effect of Timed İnsemination on Pregnancy Rates of Cows Synchronized with PGF2α Based on Plasma Progesterone Levels

Year 1998, Volume: 14 Issue: 2, 77 - 83, 01.06.1998

Abstract

This study was conducled to [nvestigate the ellectiveness of oestrus synchronisation with PGF2o. and timed·insemination based on plasma progesterone levels in cows. The study was carried out in 34 Brown Swiss cows, aging between 3 and 5 years old. Blood samptes were coltected at ten day intervals 3 times without cyclic stage of the cows. In each sampling, the cows with high plasma progesterone levels (�.5 ng i ml) were intramuscularty in­jected with PGF2o. analogue (0.150 mg 0- eloprostenol), and inseminated at 72 and 96 th. hours fixed-tlme after the injections. Blood samples were collecled to monitore Ihe progesterone levels for pregnancy diagnosis on the day of 211h af ter inseminatlons, then rectal examination were conducted to deıect the pregnancy on the day ol 60 after the inseminations. In the first sampling. high progesterone levels were loond in 23 of 34 cows. These cows were synchro­nized with PGF2a and 16 of 23 cows became pregnant following the fixed-time inseminations. In the second samp­ ing, S ol the 11 cows had high progesterone levels and 4 ol these S cows with high progesteron levels became preg­nant after the synchronization and inseminalions. In the 3 th sampling, 3 cows had lower levels than 0.5 ng i ml plasma progesterone. Total of 31 cows were synchronized based on high progesterone levels and 20 ("lo 66.6) of these cows became pregnant lollowing the inseminations. As a resuı , synchronization done wilh PGF2o. in the cows with luteal aclivity based on plasma progesterone levels and fixed-tlme inseminalions showed satislactory pregnaney rates. Lı was also beneliclal for the diagnosis ol the cows wilh no luleal activity and elimination ol ıhe PGF2a injections ıo these cows
