AB  - The objective of this study is to analyze by generalized linear mixed modeling technique with binomial structure for reproductive characteristics in Karaka? local ewes in Turkey. The data were collected from Yuzuncu Yil University, Animal Science Breeding Farms in Turkey. A total of 83 ewes and their 94 lambs at born 2004 season were included in the analysis born over a period of one year. A log linear relationship between the mean and the factors such as age, sire (rams), type of birth and sex of lambs by the log link function and distributed as poisson. According to analysis result for GEE, effecting of ram, birth type and sex of lamb have been statistically significant (P<0.01) on the birth weight. On the other hand, effect of age of the dam has not been significantly on the birth weight. There is only investigating to effect of ram and age dam on the non-return rate. No significance effects were determined for these factors on the non-return rate. Ram produced medium (3 or 4 mass activity score) quality of the sperm have been higher birth weight than others. Male and single born lambs have been also highest birth weight. There are no differences for age of dam. However, lambs born from 2 or 3 ageing dams have slightly more born weights than others. In present study, there are no available indicator factors for non-return rate and pregnant status for investigating factors.
