Effect of Progestagen Application During Ovsynch Protocol on Pregnancy Rates of Lactating-grazing Cows

Bu çalışmanın amacı laktasyonda ve otlayan ineklerde Ovsynch protokolüne progesterone katkısının sabit zamanlı suni tohumlamada gebelik oranları üzerine etkisini test etmekti. Toplam 158 sütçü inek, rastgele iki gruba ayrıldı: Grup 1 (n = 75)'de bulunan ineklere Ovsynch protokolü uygulandı (Grup OV), Grup 2 (n = 83)'de bulunan ineklere ise Ovsynch + PRID protokolü uygulandı (Grup OV + PRID). Uygulama sonrası sabit zamanlı tohumlama ile gebelik oranları; Grup OV için %33.3, Grup OV + PRID için %53.0 olarak tespit edildi. Gebelik oranları açısından önemli derecede fark (P

Ovsynch Protokolü Sırasında Progestagen Uygulamasının Laktasyondaotlayan İneklerin Gebelik Oranları Üzerine Etkisi

The aim of this study was to test the effect of progesterone supplementation to Ovsynch protocol in lactating and grazing cows on pregnancy rate after fixed time artificial insemination (TAI). Animals, from a total of 158 dairy cows, were randomly assigned to two groups. In Grup 1 (n = 75) Ovsynch protocol was carried out (Group OV), and in Grup 2 (n = 83) Ovsynch + PRID protocol was carried out (Group OV + PRID). Conception rates following timed Artificial Insemination (TAI) were determined as 33.3% for Grup OV and 53.0% for Group OV+PRID. Differences between groups were statistically significant (P
