Abstract

Abstract: In this study, the effects of post-mating FGA/P4 and of split eCG/PMSG injections at different doses were evaluated for the induction of oestrus in Angora goats during the breeding season. In total, thirty-six multiparous does were assigned into two separate synchronisation trials. In Experiment 1 (double FGA), 22 does were administered all firstly an intravaginal sponge containing 20 mg FGA for 11 days. On day 9, the animals then received i.m. injections of 125 mg cloprostenol, and of 400 IU eCG concurrently. On day 6 post-mating, animals were randomly assigned into two groups, as control (n=13), single and double FGA group (n=9), receiving the second FGA for 11 days. In Experiment 2 (split eCG), 14 does were randomly assigned into eCG 750 and eCG 500 groups (n=7 each), with multiple injections (on 5 consecutive days) of 750 (250 and 100 in double and 50 IU at last) or of 500 IU (100 IU daily). The results showed that; i) double/post-mating FGA had no favourable effect upon the reproductive parameters studied, ii) the eCG itself led to a considerably poorer fertility and twinning in Angora does during the breeding season.

Özet

Sunulan çalışmada, üreme sezonundaki Ankara keçilerinde çiftleşme sonrası FGA/P4 ve farklı dozlarda bölünmüş eCG/PMSG enjeksiyonlarının östrus senkronizasyonundaki etkileri araştırıldı. Toplam 36 baş anaç (önceden doğum yapmış) keçi iki ayrı senkronizasyon grubuna ayrıldı. Çalışma l'de (çift doz FGA), keçilere 11 gün süreyle 20 mg FGA içeren vagina-içi sünger uygulandı. Hayvanlara 9. günde, 125 mg cloprostenol ve 400 IU eCG birlikte enjekte edildi. Çiftleşme sonrası 6. günde, hayvanlar tek (kontrol, n=13) veya çift doz FGA grubu (n=9), ikinci FGA 11 gün süreyle, olmak üzere rastgele iki deneme grubuna ayrıldı. Çalışma 2'de (bölünmüş eCG), 14 baş keçi rasgele tarzda eCG 750 ve eCG 500 gruplarına ayrılarak (n=7, her biri), ilk gruba 750 IU eCG (iki kez 250, iki kez 100 ve son kez 50 IU) verilirken, diğer gruba ise 500 IU eCG (günlük 100 IU) çoklu enjeksiyon tarzında (ardışık 5 gün süreli) olarak verildi. Sonuç olarak; i) çift doz/çiftleşme sonrası FGA uygulamasının çalışılan üreme parametreleri üzerine bir katkısının olmadığı, ii) sadece eCG uygulamasının ise yavru verimi ve ikizlik yönünden belli düzeyde daha düşük oranlara yol açtığı kanısına varıldı.
