Özet:

 The objective of this study was to investigate the impact of estrus synchronization on certain fertility parameters in Tuj ewes during the non-breeding season, using short-term ST or long-term LT progesterone P4-impregnated sponge and equine chorionic gonadotropin eCG. Forty-eight clinically healthy Tuj ewes were selected and divided into three groups: Group I G1, n15, Group II G2, n18, and Group III G3, n15. G1 and G2 received hormonal treatment with a P4-impregnated sponge inserted into the vagina on day 0, and 500 IU eCG was administered intramuscularly five or ten days later, respectively. The sponges were removed from the vagina seven days after insertion for G1 and 12 days after insertion for G2. G3 did not receive any hormone treatment. All groups were exposed to the ram 24 hours after sponge removal. Estrus was monitored every six hours for five days, and pregnancy was confirmed by transrectal ultrasonography. The estrus rate, estrus onset time, and pregnancy rate were significantly different between G1 and G3 and between G2 and G3 p0.05. However, there was no difference between the treatment groups G1 and G2 in terms of fertility parameters p0.05. In conclusion, ST or LTP4-impregnated vaginal sponge treatment was equally effective on fertility parameters in Tuj ewes during the non-breeding season.

 Bu çalışmanın amacı, kısa ST veya uzun süreli LT progesteron P4-emdirilmiş sünger ve kısrak koriyonik gonadotropin eCG kullanarak östrus senkronizasyonunun Tuj koyunlarında bazı fertilite parametreleri üzerindeki etkisini araştırmaktır. Klinik olarak sağlıklı 48 Tuj koyunu seçildi ve üç gruba ayrılmıştır: Grup I G1, n15, Grup II G2, n18 ve Grup III G3, n15. G1 ve G2, P4-emdirilmiş sünger vaginaya yerleştirilerek hormon tedavisi aldı ve sırasıyla beş veya on gün sonra 500 IU eCG intramusküler olarak uygulandı. Süngerler, G1 için yerleştirme tarihinden yedi gün sonra ve G2 için yerleştirme tarihinden 12 gün sonra vaginadan çıkarıldı. G3 herhangi bir hormon tedavisi almadı. Tüm gruplara, sünger çıkarılmasından 24 saat sonra koç katımı yapıldı. Östrus, beş gün boyunca her altı saatte bir izlendi ve gebelik transrektal ultrasonografi ile doğrulandı. Östrus oranı, östrus başlangıçzamanı ve gebelik oranı G1 ve G3 ve G2 ve G3 arasında anlamlı şekilde farklıydı p0.05. Fakat tedavi grupları arasında G1 ve G2 arasında fertilite parametreleri açısından fark tespit edilmedi p0.05. Sonuç olarak, kısa veya uzun dönem P4-emdirilmiş vaginal sünger tedavisi, Tuj koyunlarında üreme sezonu dışında fertilite parametreleri açısından eşit derecede etkilidir.
