Abstract

This study was conducted to investigate the effect of interval from first detected mounting activity to artificial insemination on conception rates in cows.A total of 94 cows were used in this study. Cows were visually observed three times a day for behavioral signs of estrus. Progesterone levels were determined using progesteron test kits to confirm whether the cows were in estrus at insemination time. They were divided into three groups according to interval from first mounting activity to artificial insemination. Then, they were inseminated between 0 h and 8 h (Group I), 8 h and 16 h (Group II), 16 h and 24 h (Group III) after first detected mount. The conception rates were determined by rectal palpation on 55-60th days following artificial insemination.The average rate of cows which showed behavioral signs of estrous but had high concentrations of progesterone (>1 ng/ml) was recorded as 16.0%in this study. It was observed that the conception rate was significantly lower in cows which inseminated within 8 h after first detected mount (p

Özet

Bu araştırma, ineklerde tespit edilen ilk atlama davranışından suni tohumlama zamanına kadar geçen sürenin gebelik oranları üzerine etkisini araştırmak amacıyla yapıldı.Çalışmada, toplam 94 inek kullanıldı. İnekler gözlem yoluyla günde 3 kez östrusun davranışsal belirtileri yönünden kontrol edildi. Tohumlama anında ineklerin östrusta olup olmadıklarının doğrulanması için progesteron test kitleri kullanılarak progesteron seviyeleri belirlendi. Östrusta olduğu belirlenen inekler 3 gruba ayrılarak ilk atlama davranışının görülmesinden sonraki 0 ile 8. saatler (Grup I), 8 ile 16. saatler (Grup II) ve 16 ile 24. saatler (Grup III) arasında tohumlandı. Tohumlamayı takip eden 55–60. günlerde rektal palpasyonla gebelikler teşhis edildi.Bu çalışmada, östrusun davranışsal belirtilerini göstermesine rağmen yüksek progesteron düzeyine(>1 ng/ml) sahip ineklerin oranı %16,0 olarak kaydedildi. İlk atlama aktivitesinin belirlenmesinden sonraki 8 saat içerisinde tohumlanan ineklerin gebelik oranının (%42,9) diğer gruplardaki ineklerinkine göre (%78,1 ve %73,1) önemli derecede (p
