This study was carried out on 67 Karakaş ewes and 64 lambs obtained fromsheep between February and March 2003 in the arable field of Demirtaş village ofYağmurlu, Hakkari.In this study, the body weights and the daily live weight gains of the lambsin various periods and reproductive traits of Karakaş ewes were investigated.Adjusted means of the Karakaş lambs were 3.09 ± 0.03, 7.51 ± 0.94, 10.84± 1.36, 15.13 ± 1.89, 19.91 ± 2.49, 25.03 ± 3.13 and 30.09 ± 3.76 kg for birthweight, live weight of, 30th, 60th, 90th (weaning), 120th, 150th and 180th days,respectively. The avarege daily weight gains of lambs were 147.24 ± 18.41, 129.25± 16.16, 133.82 ± 16.73, 140.20 ± 17.52, 146.25 ± 18.28, 149.99 ± 18.75, 111.25 ±13.91, 127.10 ± 15.89, 142.97 ± 17.87 and 166.16 ± 20.77 g for between birth-30th,birth-60th, birth-90th, birth-120th, birth-150th, birth-180th, 30th-60th, 30th-90th,60th-90th and 90th-180th day, respectively.The averages of reproductive traits such as sterility, fertility, twins, aborted,pregnancy, fecundity, litter size and gestation efficiency were 4.48 %, 86.57 %,13.79 %, 8.96 %, 95.53 %, 0.96, 1.10 and 7.63 kg, respectively.Key words: Ewes, Growth, Karakaş, Lamb, Reproductive Traits.
