Abstract

Bu çalışmanın amacı, üreme mevsimi dışında İvesi koyunlarında PMSG ile birlikte farklı progestagen uygulamalarının etkinliğini araştırmaktı. Toplam 48 baş koyun 4 eşit gruba bölündü. Grup I, vaginal süngerler (30 mg FGA) koyunlara 7 gün süreyle uygulandı, daha sonra 7. günde çıkarılan süngerin yerine yeni sünger tekrar 7 gün süreyle yerleştirildi. Grup II ve Grup III’de vaginal süngerler sırasıyla 7 ve 14 gün uygulandı. Grup IV, kontrol grubunu oluşturdu. Çalışma gruplarının tümünde süngerlerin çıkarıldığı anda 500 IU PMSG yapıldı. Östrusa gelme oranı, gebelik ve kuzulama oranları, süngerin çıkarılmasından sonra östrusa gelme aralığı ve östrus süresi ile verimlilik gibi parametreler değerlendirildi. Östrusa gelme, gebelik ve kuzulama oranları ile doğurganlık açısından Grup I, II ve III arasında önemli bir farklılık bulunmadı. Buna ilaveten, tüm gruplarda östrus süresi istatistiksel açıdan farklı olmadı. Ancak, süngerlerin çıkarılmasından sonra östrusa gelme süreleri açısından Grup II (53±3,37 saat) ve Grup III (41,5±1.81 saat) arasında önemli farklılıklar bulundu (p<0.05). Koç katımından sonra progesteron (P4) seviyesi hafif arttı ama bu artışı takiben koç katımından iki hafta sonra azaldı (p<0.05). Sonuç olarak, sünger uygulama sürecinde yüksek progesteron konsantrasyonu oluşturmak için ardışık olarak iki defa sünger kullanılması hiç bir avantaj sağlamadı. Buna ilaveten, üreme mevsimi dışındaki İvesi koyunlarında kısa süreli (7 gün) sünger uygulamasının uzun süreli uygulama kadar etkili olduğu bulundu

Abstract

The aim of this study was to evaluate the effectiveness of different treatment methods of progestagen with PMSG in Awassi ewes out of the breeding season. A total of 48 ewes were divided into four groups equally. In Group I, vaginal sponges (30 mg fluorogestone acetate; FGA) were administered to ewes for seven days; afterwards vaginal sponge removal at the end of 7th days and new vaginal sponge replaced for seven days in the same group. Vaginal sponges were administered for 7 days and 14 days in Group II and Group III, respectively. Group IV (Control) served as control group. In all experimental groups, 500 IU PMSG was given at sponge removal. Parameters such as estrus response rate, pregnancy and lambing rates, interval from sponge withdrawal to onset of estrus, duration of estrus and fecundity were evaluated. There were no significant differences in terms of estrus response rate, pregnancy rate, lambing rate, and fecundity between the Group I, II and III (p>0.05). In addition to this, any difference in the duration of estrus was not observed in all groups. However, variations in the interval from sponge removal to estrus was found significant (p<0.05) differences between Group II (53±3.37 h) and Group III (41.5±1.81 h). A slight increase in progesterone levels was observed after ram introduction, but a significant decrease in progesterone levels was found after two weeks from ram
