Östrus Senkronize İvesi Koyunlarında hCG ve Beta Karoten + Vitamin E'nin Tek Başına veya Birlikte Kullanımının Fertilite Üzerine Etkileri

Öz

Bu çalışma Diyarbakır'da dört farklı çiftlikte geçiş döneminde (aşım sezonundan 1,5-2 ay önce) yürütülmüştür. Toplam 306 İvesi koyunu çalışma öncesinde dört gruba ayrılmıştır. Tüm gruplara 12 gün boyunca progesteron süngeri, sünger çıkarılmadan iki gün önce PGF2α, sünger çıkarma gününde 600 IU eCG ve çiftleşme gününde 150 IU hCG uygulanmıştır. Kontrol grubundaki koyunlar (n= 91) herhangi bir ek tedavi almamıştır. Vitamin grubundaki koyunlara (n= 61) sünger yerleştirilmeden 7 gün önce ve çiftleşme gününde iki kez Beta (β) karoten + E vitamini uygulandı. HCG grubundaki koyunlar (n= 74) çiftleşmeden sonraki 12. günde 150 IU hCG ile tedavi edilmiştir. Vitamin + hCG grubundaki koyunlar (n= 80) β-karoten + E vitamini ve hCG ile tedavi edildi. Aşım için ayakta duran koyunlar östrusta kabul edildi ve çiftleştirildi. Gebelik teşhisi çiftleşmeden sonraki 30. günde ultrasonografi ile yapıldı. Kontrol, hCG, vitamin ve vitamin + hCG gruplarında kızgınlık, gebelik, kuzulama, döl verimi ve çoğuz doğum oranları benzerdi (P˃0.05). İvesi koyunlarında geçiş döneminde östrus senkronizasyonuna ek olarak vitamin (β-karoten + E vitamini), hCG veya her ikisiyle birlikte yapılan uygulamaların fertilite parametrelerini önemli ölçüde iyileştirmediği sonucuna varıldı.

Abstract

The present study was conducted at four different farms in Diyarbakır during the transition period (1.5 to 2 month before breeding season). A total of 306 Awassi ewes were divided into four groups before the study. All groups were treated with a progesterone sponge for 12 days, PGF2α on two days before sponge removal, 600 IU eCG on sponge removal day and 150 IU hCG on the day of mating. The control group of ewes (n= 91) did not receive any additional treatment. The ewes in vitamin group (n= 61) were treated twice with Beta (β) carotene + vitamin E on 7 days before the sponge insertion and the day of mating. The ewes in hCG group (n= 74) were treated with 150 IU hCG on day 12 after mating. The ewes in vitamin + hCG group (n= 80) were treated with β-carotene + vitamin E and hCG. Ewes standing to be mounted were considered in estrus and mated. Diagnosis of pregnancy was made by ultrasonography on the 30th day after mating. In control, hCG, vitamin, and vitamin + hCG groups, estrus, pregnancy, lambing, fecundity and multiple birth rates were similar (P>0.05). It was concluded that the treatments with vitamins (β-carotene + vitamin E), hCG or both, in addition to estrus synchronization during transition period in Awassi ewes did not significantly improve the fertility parameters.
