The aim of this study was to determine the effects of ewe age on conception rates, prolificacy, productivity, and viability using 1,408 Akkaraman ewes from the Yarma neighborhood in Konya City, Turkey. The least-squares means for these parameters of all flocks were 91.27 ± 0.11, 135 ± 0.30, 86.38 ± 0.01, and 94.63 ± 0.01%, respectively. In addition, the effects of the sex of the offspring and the birth type (i.e., single, twin) on viability were included in the study. Except for viability, the effect of ewe age on these parameters was statistically significant (P < .01). Two-year-old ewes exhibited the maximum productivity. The year factor (i.e., time of year, weather, etc.) had a significant effect on all parameters (P < .01 and P < .05). Sex and birth type effects on viability were not statistically significant.

In this study, greasy fleece yield and some wool characteristics and the effects of gender, age and live weight on these characteristics were investigated in 60 heads of Anatolian Merino sheep reared in Babayakup neighborhood of Polatlı District of Ankara. Least squares means of live weight before shearing, greasy fleece yield, fiber diameter, fiber length, breaking strength, fiber elasticity and clean fleece percentage were found to be 68±0.89 kg, 2.97±0.19 kg, 24.42±0.49 µm, 7.92±0.36 cm, 19.15±1.25 Cn/tex, 25.38±1.83 %, 48.16±2.17 %, respectively. The effects of gender (p<0.001) and age (p<0.05) on live weight before shearing, the effects of body weight group (p<0.05) on fiber diameter and the effects of gender (p<0.05) on fiber length were found to be significant. According to the findings, it was concluded that the fiber diameter value of the research material sheep is 60 sortiman, therefore it will be evaluated in the class of fine wool sheep and it is suitable for worsted fabric production.
