Abstract

The present study was aimed at the investigation of the effects of Recombinant Follicle Stimulating Hormone (rFSH) on fertility in Awassi ewes synchronized with PGF$_2 alpha$ in the breeding season. The fifty thoroughbred Awassi ewes used in the study were injected twice with 0.150 mg of Tiaprost (PGF2α, Iliren®) at a 10-day interval. Following the second PGF$_2 alpha$ injection, the ewes were randomly distributed into two equal groups. The ewes included in the first group were not subjected to any additional injection and were referred to as the PGF$_2 alpha$ group (Group 1, n=25). The animals included in the second group (Group 2, n=25) were administered 10 IU Follitropin (rFSH, Puregon®), diluted 1:10 with physiological saline, 24 hours before the second PGF2α injection. Ewes were tested for estrus by a fertile teasing ram three times a day (06.00, 14.00 and 20.00 h), for one hour each time. Ewes exhibiting estrus were mated naturally. Pregnancy was determined by transrectal ultrasonography on 40. d after mating. Estrus was observed at a rate of 88.0 % in Group 1 and 92.0 % in Group 2. The rate of pregnancy was 100 % in the first group and 95.6% in the second group. The rate of lambing was 100 % and 95.5 % in Groups 1 and 2, respectively. Furthermore, twin pregnancy rates were 4.5 % in the first group and 57.1% in the second group. While differences between the groups were determined to be significant (p

Özet

Sunulan çalışmanın amacı, aşım sezonunda PGF2α ile senkronize edilmiş İvesi Koyunlarında Recombinant Follikül Stimüle Hormonun (rFSH) fertilite üzerine etkisi araştırmaktır. Çalışmada kullanılan toplam 50 baş safkan İvesi koyuna 10’ar gün ara ile iki defa 0.150 mg dozunda Tiaprost (PGF$_2 alpha,$ Iliren®) enjeksiyonları yapıldı. İkinci PGF$_2 alpha$ enjeksiyonları yapıldıktan sonra koyunlar rastgele iki eşit gruba ayrıldı. Birinci gruptaki koyunlara ilave bir enjeksiyon yapılmadan (Grup 1, n=25) PGF$_2 alpha$ grubu, ikinci gruptaki (Grup 2, n=25) koyunlara ise ikinci PGF2α enjeksiyondan 24 saat önce 1/10 oranında serum fizyolojik ile sulandırılıp 10 IU Follitropin (rFSH, Puregon®) enjeksiyonu yapıldı. Östruslar (Saat 06.00, 14.00 ve 20.00) günde üç kez 1’er saat süreyle fertil bir arama koçu tarafından test edildi. Östrus gösteren koyunlara doğal aşım yaptırıldı. Gebelikler doğal aşımı takip eden 40. günde transrektal ultrasonografi ile tespit edildi. Östruslar Grup 1’de % 88.0, Grup 2’de % 92.0 oranında gözlendi. Gebelik oranı ise birinci grupta % 100 elde edilirken bu oran ikinci grupta % 95.6 olarak elde edildi. Kuzulama oranı Grup 1’de % 100 Grup 2’de ise % 95.5 olarak gerçekleşti. İkizlik oranları birinci grupta % 4.5, ikinci grupta % 57.1 olarak gerçekleşti. Gruplar arasında farkın önemli olduğu saptanırken (p
