The animal materials of this study consisted of 581 head ewes and 643 head lambs obtained from different farms. It was determined lambing rate, infertility rate, single birth rate, twinning birth rate, female birth rate, male birth rate, and litter size at birth, 95.5%, 4.4%, 82.7%, 17.3%, 46.9%, 53.1% and 1.16%i, respectively. The birth weight and weaning weight of lambs were established as 4.16 kg and 21.50 kg, respectively. In general, the survivability rate of lambs until weaning was determined as 95.80 %. These rates were 94.70, 96.77, 98.91, and 88.04% for female, male, single, and twin lambs, respectively. In addition, the survivability rate of lambs born to 2-, 3-, and 4-year-old ewes was 92.59%, 94.33% and 97.35% respectively. As a result, when the obtained data are evaluated, it can be said that the lambing and twinning rates are quite good according to the field conditions, and the infertility rate is at the desired levels.}, number={5}, publisher={Kahramanmaras Sutcu Imam University}
