Abstract :This study was conducted to investigate effects of flushing during the normal breeding season on reproductive performance of Akkaraman ewes and environmental factors birth weights of lambs in Akkaraman sheep. A total of 120 ewes were used in this study. The eweswere allocated in equal numbers to 2 groups. The fırst group was control group. the second group was flushing group. While sheep in the control group received 8.61 MJ per dav, sheep in the flushing group received 13.68 MJ per dav. Rates of estrus. conception. birth and single-twin lambing and litter size were 93.33. 86.67, 86.67. 90.38. 9.62 %and 1.096 in the control group and 98.33. 88.33. 88.33. 79.25.20.75 %and 1.208 in the flushing group. respectively. Twinning rate was 11.13% greater in the flushing group compared with the control group P>0.05 . In conclusion. there were not signifıcant differences between the mean values of reproduction characteristics of Akkaraman ewes subjected to low and high level cnergy of nutrition. Furthermore, effects of age of dam. type of birth and sex on birth weights of Akkaraman lambs were signifıcant P0.05Keywords : Flushing, Akkaraman koyun, döl verimi, doğum ağırlığı
