Abstract

Objective: This study investigated the effectiveness of the single-dose treatment of three different commercial products on reproductive performance in Kıvırcık ewes during the transition to the breeding season.
Material and Methods: Ninety-eight Kıvırcık ewes aged 3-4 years and weighed from 50 to 55 kg have been used in this study. The ewes used in the study were randomly divided into four different (PGF2α, Vit.E/Se, multivitamin and control) groups. All these injections were applied to all groups one week before the ram-mating process.
Results: The difference between the control group and the treatment groups was statistically significant (P < 0.01); however, the difference between PGF2α and Vit.E/Se, and multivitamin treatments was insignificant (P > 0.05) in terms of multiple-birth rate. The highest value in terms of litter size was found in the PGF2α treatment group.
Conclusion: In the study, all three treatments were more successful than the control group in inducing estrus and pregnancy in Kıvırcık ewes during the transition from anoestrus period to the breeding season and all ewes healthily gave birth.

Abstract

Amaç: Bu çalışmada üreme mevsimine geçişte Kıvırcık ırkı koyunlarda döl verim performansı üzerine üç farklı ticari ürünün tek doz uygulanma etkinliği araştırılmıştır.
Materyal ve Metot: Bu çalışmada 3-4 yaşlarında ve 50 ila 55 kg ağırlığında 98 Kıvırcık koyunu kullanılmıştır. Çalışmada kullanılan koyunlar rastgele dört farklı (PGF2α, Vit.E/Se, multivitamin ve kontrol) gruba ayrılmıştır. Tüm bu enjeksiyonlar koç katım sürecinden bir hafta önce tüm gruplara uygulanmıştır.
Bulgular: Kontrol grubu ile uygulama grupları arasındaki fark istatistiksel olarak anlamlıydı (P < 0.01); ancak PGF2α ile Vit.E/Se ve multivitamin uygulamaları arasındaki fark çoğuz doğum oranı açısından önemsizdi (P > 0.05). Yavru büyüklüğü açısından en yüksek değer PGF2α grubunda bulunmuştur.
Sonuç: Çalışmada, anöstrus döneminden üreme mevsimine geçişte Kıvırcık koyunlarında östrus ve gebeliği teşvik etmede her üç uygulama da kontrol grubundan daha başarılı olmuş ve tüm koyunlar sağlıklı bir şekilde doğum yapmıştır.
