Abstract :In this study, 3581 Akkaraman and Awassi ewes were used in order to determine the effects of age, year and breed on the conception rate, prolificacy, viability and productivity. The least-squares means for these parameters of all flock were found as follows; 91.65±0.80 %, 127.74±1.26 %, 95.56±0.48 % and 110±1.57 %, respectively. In addition, the effects of sex of lamb and birth type on viability were also studied. Except for conception rate, effects of the age on these parameters were found to be statistically significant insert ignore into journalissuearticles values(p<0.01);. The maximum productivity was obtained with 5-years old ewes. Effect of breed was significant only on the prolificacy insert ignore into journalissuearticles values(p<0.05);. With regard to prolificacy, Awassi ewes were superior to Akkaraman insert ignore into journalissuearticles values(129.27 % vs. 126.21 %);. The year factor had a significant effect on all parameters insert ignore into journalissuearticles values(p<0.01);. Sex effect on the viability was not significant, but birth type effected viability significantly; single lambs being superior to twin ones.
