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
