Abstract

Araştırma, Diyarbakır ilinde üreme mevsimi dışında İvesi ırkı 237 koyun üzerinde yürütüldü. Östrus senkronizasyonu yapılan koyunlar suni tohumlama işleminden hemen önce vajina tabanındaki servikal mukus (SM) miktarına göre “yok” (n= 25), “az” (n= 79) veya “bol” (n= 133) olarak sınıflandırıldı. Koyunlar östrustan 12-18 saat sonra intra-servikal yolla 200×106 motil spermatozoa içeren taze-sulandırılmış sperma ile tohumlandı. Gebelik oranları, suni tohumlamadan (ST) 30-40 gün sonra ultrason aracılığı ile belirlendi. Çara durumuna göre “yok”, “az” ve “bol” olarak sınıflandırılan koyunların gebelik oranları sırasıyla %36.4, %50.6 ve %45.1 olarak bulundu (p>0.05). Çalışmamızdan; İvesi koyunlarda ST öncesinde vajinadaki SM miktarının gebelik oranlarını istatistiksel olarak önemli düzeyde etkilemediği sonucu çıkarılmıştır. Ancak SM miktarına göre “yok” ve “az” olarak sınıflandırılan koyunların gebelik oranları arasında kayda değer sayısal farklılığın olması, SM miktarının fertiliteyi etkileme potansiyelinin olabileceğine işaret etmektedir. Bu nedenle daha fazla koyunun dahil edildiği yeni çalışmalara ihtiyaç bulunmaktadır.
