Özet
Bu çalışmada, geçiş dönemi başındaki koyunlarda farklı progesteron ve PGF2? uygulamalarının, östrüs senkronizasyonu ve ovaryum aktivitesini uyarmadaki etkisi araştırıldı. Araştırmada toplam 75 koyun kullanıldı ve koyunlar 5 gruba ayrıldı. Birinci gruptaki koyunlara (n15) 30 mg flourogesterone acetate (FGA-30), ikinci gruptaki koyunlara (n15) 40 mg flourogestene acetate (FGA-40) içeren süngerler vagina içine yerleştirildi. Her iki gruptaki süngerler 12 gün sonra uzaklaştırıldı. Üçüncü gruptaki koyunlara (n15) 3 mg Norgostomet içeren kulak implantı (N-İMPLANT) kulak derisi altına yerleştirildi ve 9 gün sonra uzaklaştırıldı. Dördüncü gruptaki koyunlara (n15) Tiaprost tromethamine (PGF2?; 0.294 mg) 9 gün arayla iki kez kas içi yolla enjekte edildi. Beşinci grup (n15) kontrol olarak oluşturuldu. Vaginal süngerlerin, implantların çıkarılmasını ve ikinci PGF2? enjeksiyonunu takiben tüm çalışma gruplarındaki koyunlara kas içi yolla 600 IU PMSG enjekte edildi. Östrüste oldukları belirlenen koyunlara doğal aşım yaptırıldı. Östrüs görülme oranları FGA-30 ve N-İMPLANT gruplarında (%93.3), FGA-40 grubunda (%86.6) ile PGF2? (%53.3) ve Kontrol (%26.6) gruplarına göre istatistiki açıdan önemli şekilde yüksek belirlendi. Gebelik oranları ise FGA-30 (%93.3) ve N-İMPLANT (%93.3) gruplarında, PGF2? (%53.3) grubuna göre belirgin olarak yüksek bulundu. Kuzulama oranı açısından deneme grupları arasında önemli bir farklılık gözlenmedi. Çoklu doğum oranı N-İMPLANT grubunda (%35.7), PGF2? (%0.0) grubuna göre belirgin olarak yüksek bulundu. Sonuç olarak, geçiş dönemi başındaki koyunlarda PGF2?‘nın çift doz uygulanmasıyla farklı progesteron tedavileri kıyaslandığında PGF2?‘nın yeterli cevap oluşturamadığı belirlendi.
The efficiency of different progesterone and PGF2α treatments in the induction of ovarian activity and synchronization of oestrus was investigated the beginning transitional period in sheep. A total of 75 ewes were used in the experiment. Animals were divided into 5 groups. Vaginal sponges containing either 30 mg or 40 mg fluorogestene acetate (FGA) were inserted into the vagina of ewes in the first (FGA-30; n15) and second (FGA-40; n15) groups, respectively. The sponges were withdrawn after 12 day. In the third group of ewes (n15), ear implants containing 3 mg norgestomet (N-IMPLANT) were inserted subcutaneously and removed after 9 day. In the fourth group (n15), Tiaprost tromethamine (PGF2α; 0.294 mg) was intramuscularly injected twice at an interval of 9-d. The control (Control) group is consisted of 15 ewes. After the second PGF2α injections and the withdrawal of the sponges and implants, 600 IU PMSG was injected to all ewes in the FGA-30, FGA-40, N-Implant and PGF2α groups. After the detection of oestrus ewes, they were naturally mated. Oestrus response rates were significantly higher in the groups FGA-30 (93.3%), and N-IMPLANT (93.3%) than those in the groups PGF2α (53.3%) and Control (26.6%). However, oestrus rates in the group FGA-40 were only significantly higher (86.6%) than those in the group Control (26.6%). The pregnancy rates in the groups FGA-30 (93.3%) and N-IMPLANT (93.3%) were significantly higher than that in the group PGF2α (53.3%). No significant difference was observed among the groups FGA-30, FGA-40, N-IMPLANT and PGF2α with respect to lambing rates. Multiple birth rates were significantly higher in the group N-IMPLANT (35.7%) than in the group PGF2α (0.0%). As a conclusion, a double dosed application of PGF2α was observed to be inefficient compared to different progesterone treatments in ewes the beginning transitional period.
