Abstract

46 Brown-Swiss virgine heifers, between 2 -5 years old were used ın this study. Without controlling the phase of the sexuel cycle, 500 mcg Cloprostenol was injected i.m. in heifers and estrous symptoms were detected following 5 days. Artificial Inseminations were done during the standing estrouses. The heifers were not seen estrous symptoms within 5 days, were injected second 500 mcg Cloprostenol 11 days later and were inseminated 72. and 96. hours after injections. Estrous, conception and pregnancy rates obtained from first and second group of heifers were 86.95 %, 50 %, 43.47 % and 100 %, 66.66 %, 66.66 % respectively. Looking the results of first cloprostenol injections, it's decided that better fertility scores could be obtained 48. and 72. hours inseminations after 2 nd cloprostenol injections in these animals

Özet

Bu çalışmada değişik nedenlerle hiç gebe bırakılmamış ve yaşları 2-5 arasında değişen 46 İsviçre Esmeri ırkından düve kullanıldı. Seksüel siklusun farklı dönemlerinde bulunan düvelere 500 mcg cloprostenol i.m. enjekte edildi ve beş gün süre ile östrüs belirtileri araştırıldı. Östrüs gösterenler bu sürenin ikinci yarısında tohumlandılar. Östrüs göstermeyen hayvanlara ise onbir gün sonra ikinci 500 mcg. Cloprostenol i.m. enjekte edildi ve östrüs belirtileri araştırılmadan 72. ve 96. saatlerde iki kez tohumlandılar. İlk tohumlama sonrasında, senkronizasyon, konsepsiyon ve gebe kalma oranları sırasıyla, ilk grupta % 86.95, % 50, % 43.47, ikinci grupta ise % 100, % 66.66, % 66.66 olarak belirlendi. İlk grupta östrüslerin başlangıç ve yoğunlaştığı saatler gözönünde tutularak, ikinci grupta 48-72. saatlerde yapılacak tohumlama ile fertilite oranının daha yüksek olabileceği kanısına varıldı.
