Abstract

The aim of this study was to investigate the effect of two different superovulator agents on oocyte quality, quantity and in vitro fertilization of rabbits. In this study 16 female and 2 male New Zealand White rabbits wereused. A group of female rabbits (n=8) was intramusculary injected with 75 IU PMSG 3 times with 24 hours intervals. Another group of female rabbits (n=8) was injected (intramuscular) with 7.5 IU FSH twice daily during three consecutive days. Twentyfouf hours after the last hormon injection both groups of animals ovulation was induced by an intravenous injection of 100 IU hCG. Fifteen hours after hCG injection, oocytes were collected by flushing the oviducts. A total of 34 oocytes were obtained from PMSG applied group and 77 oocytes were collected from FSH applied group. Difference between groups for oocyte number was found significant (p0.05). Detection of embryos reaching to 2-ceIl stage was approved as criterion for the assesment of in vitro fertilization of oocytes. At the end of the culture period, the fertilization rates were 44.83 % (13/29) for superovulated group with PMSG and 52.38 % (33/63) for superovulated group with FSH. Although differences were not statistically significant (p>0.05), numerical differences supported the use of FSH to superovulation in rabbits. It was concluded that although more efficient superovulation in rabbits may be obtained by FSH, PMSG can be used due to advantages like lower cost and easier handling.

Özet

Bu çalışmada iki farklı süperovülatör ajanın tavşan oositlerinin kalite, kantite ve in vitro fertilizasyonu üzerine etkisini araştırmak amaçlanmıştır. Araştırmada ,16 dişi 2 erkek Beyaz Yeni Zelanda ırkı tavşan kullanılmıştır. Bir grup dişi tavşana (n=8) kas içi yolla 24 saat arayla 3 kez 75 IU PMSG, diğer bir grup tavşana (n=8) ise kas içi yolla günde 2 kez 3 gun süreyle 7.5 IU FSH enjekte edilmiştir. Son hormon uygulamasından 24 saat sonra her iki gruba 100 IU hCG damar içi yolla enjekte edilmiştir. HCG enjeksiyonundan 15 saat sonra oviduktlar yıkanarak oositler toplanrnıştır. PMSG uygulanan grupta toplam 34 adet oosit elde edilirken, FSH uygulanan grupta toplam 77 oosit alınmıştır. Gruplar arasındaki oosit sayısı farkı önemli bulunmuştur (p0.05). Oositlerin in vitro fertilizasyonunun değerlendirilmesinde, fertilizasyona alınan oositlerin ikiye bölünme aşamasına ulaşmaları kriter alınmıştır. Kültür periyodu sonunda fertilizasyon oranları PMSG uygulanan grupta % 44.83 (13/29), FSH uygulanan grupta ise %52.38 (33/63) bulunmuştur. Farkların istatistiki açıdan önemli olmamasına rağmen kantitatif farklılık tavşanlarda süperovulasyon oluşturmak için FSH kullanımını desteklemektedir (p>0.05). Ancak, tavşanlarda FSH ile daha etkili süperovulasyonun uygulanabilmesine rağmen, daha ucuz oluşu ve uygulama kolaylığı gibi avantajlarından dolayı PMSG'nin de tercih edilebileceği kanısına varılmıştır.
