The aim of this study was to compare the fertility of ewes and the survival and growth traits of lambs which were produced by two-way and three-way crossbreeding with Kıvırcık sheep, the predominant breed in the Marmara region, Chios sheep, the most prolific breed in the region and German Black-Headed Mutton (GBM), the mutton breed which exhibits the best adaptation to the environmental conditions of the region. In the study, it was determined that the fertility of the Kıvırcık, GBM x Kıvırcık and GBM x F_1 (Chios x Kıvırcık) genotypes were 76.66%, 81.13% and 85.29% for pregnancy and birth rates; …

Effect Of Flushing And Oestrus Synchronization Application On Fertility In Akkaraman Sheep, Fi̇kret Esen, Tanzer Bozkurt
Turkish Journal of Veterinary & Animal Sciences
In this study, the effect of flushing and oestrus synchronization applications on fertility in Akkaraman sheep was investigated. The research was carried out in 78 Akkaraman sheep at the second lactation. The sheep were randomly allocated into two groups; one being the experimental group and the other the control group. Vaginal sponge containing fluorogestone acetate (FGA) and oestrus synchronization using 600 I.U. PMSG was applied to the experimental group. Flushing was also applied only to the sheep in the experimental group. Pregnancy rates of 90% and 92% were obtained in the experimental and control groups, respectively. 87% of the pregnant …
