TI  - Fertility Traits of Kangal Akkaraman Sheep Reared in Breeder Conditions in Sivas Province
AB  - The aim of the study was to determine the fertility traits of the Kangal Akkaraman sheep in Yildizeliand Central districts of Sivas. In this study, six years data obtained from breeders between 2013 and2018 were used in National Animal Improvement Project coordinated by the Turkish Ministry ofAgriculture and Forestry. In the first year of the study, 70 enterprises in 48 villages from both districtsincluded in the projects and these were reduced to 57 enterprises in 33 villages in the sixth year. Duringthe six-year period, 86116 lamb records obtained from a total of 76383 ewes in all enterprises wereevaluated. Overall average birth rate was 92.7%. While the differences between years were statisticallysignificant, differences between districts were not significant. Thetriplet births were also observed butthey were not evaluated separately because of their low rate (0.1%), so they were included in twin birthsand evaluated as twins. The average twin birth rate was 22% and differences between years, districtsand mating periods (five months between August and December) were significant for that. Overallaverage weaned lamb rate or the survival rate of the weaning period was 91.3% and differencesaccording to years, districts and lambing periods (five months between January and May) werestatistically significant for that. According to the values obtained from 5147 lamb records that were bornfrom 4242 ewes of known age in a sub-project of year 2013; the ages (1-10) of sheep were found to havean effect on the birth type, while it was found to be statistically insignificant for the survival rate.According to the results of the research, it would be useful to take into account the factors that increasefertility in order to maximize profitability in the study area and enterprises with similar conditions.
