Özet
In this study, it was aimed to determine the performance of Awassi sheep and their lambs in different season within the scope of the national breeding project carried out in Gaziantep. For this purpose, a total of 23490 heads of ewes and its lambs reared in different herds and under natural conditions were used in Gaziantep. The study covers the period between 2014 and 2017. The preliminary descriptive statistics showed that 35.24% and 25.47% of the ewes gave birth in January and December, respectively. Furthermore, the lamb survival rate at the weaning age was calculated to be 97.54% in February and 97.52% in December. The highest and the lowest birth weights were detected as 4.2 ± 0.01 kg and 2.7 ± 0.09 kg in January and May, respectively (P
