The Kivircik is raised in the Thracian, southern and eastern provinces of the Marmara region and in some Aegean provinces. It constitutes around 6-7% of the total sheep population in the country. To improve the body performance and fleece quality of indigenous sheep breeds, German Mutton Merino sheep were imported to Turkey in the 1930s. The Karacabey Merino sheep were obtained by crossbreeding German Mutton Merino with indigenous Kivircik sheep at Karacabey state farm (Yalcin, 1986). Karacabey Merino is dual purpose (meat and wool) sheep breed. At present, there are approximately 0.85 million purebred Karacabey Merino sheep in Turkey (Ekiz et al., 2004).
