Abstract

In present study, the effect of ovsynch protocol started during follicular or luteal phase of estrous cycle on the follicular and luteal synchronization and pregnancy rate in heifers was investigated. Heifers received intramuscularly GnRH-agonist (10 μg buserelin acetate, first GnRH), PGF2α (150 µg dcloprostenol, PG) and second GnRH-agonist (second GnRH) on 0, 7 and 9 day, respectively, and they were inseminated at 18 h after the last injection (ST). On day 0, heifers were divided into two groups according to their plasma progesteron concentrations; Group I (n=13): progesterone concentration 0.05). In , ovsynch started during follicular and luteal phase of cycle did not affect the follicular and luteal synchronization and pregnancy rate in heifers according to the results of this study.

Özet

Sunulan çalışmada düvelerde östrüs siklusunun folliküler veya luteal evresinde başlatılan ovsynch protokolünün folliküler ve luteal senkronizasyon ve gebelik oranı üzerine etkisi araştırıldı. Düvelerin östrüs siklusu 0, 7 ve 9. günlerde sırasıyla GnRH (10 μg buserelin asetat, birinci GnRH), PGF2α (150 µg d-kloprostenol, PG) ve GnRH (ikinci GnRH) uygulamalarıyla senkronize edildi. Düveler son enjeksiyondan 18 saat sonra tohumlandı (10. gün, ST). Düveler, 0. gün plazma progesteron konsantrasyonlarına göre iki gruba ayrıldı; progesteron konsantrasyonu 0.05). olarak bu çalışmada elde edilen sonuçlara göre düvelerde östrüs siklusunun folliküler veya luteal evresinde başlatılan ovsynch yönteminin folliküler ve luteal senkronizasyon ve gebelik oranı üzerine farklı bir etkisi olmadı.
