Materials and Methods: This research has been carried out on 4 and 5+ years old aged 70 Pırlak ewes maintained Afyon Kocatepe University Livestock Research and Application Center, sheep breeding unit in 2009.

Results: The least squares means of milk yield and lactation length were 76.98 ± 4.12 kg and 120.79 ± 2.52 days. Average daily milk yield, fat percentage and log somatic cell counts at 60 and 90 days of lactation were 680.28 ± 40.01 and 431.94 ± 27.37 g, 4.97±0.16 % and 7.88±0.27 %, 4.66± 0.11 and 5.66±0.13 respectively. Udder depth, udder circumference, right teat length, and right teat diameter were 15.25±0.26, 40.94±0.77, 2.77±0.07 and 1.58±0.04 cm for 60 days of lactation and 14.76±0.29, 34.79±0.66, 2.66±0.07 and 1.44±0.03 cm for 90 days of lactation, respectively. The significant coefficients of phenotypic correlations between milk yield and right and left udder cistern depths (0.49, 0.43) were positive and in desired way.

Conclusions: It was concluded that the lactation milk yield was similar with other Turkish native sheep breeds and Pırlak ewes were suitable to machine milking. The correlations among milk yield, somatic cell counts and udder traits were in desired ways. Therefore mentioned milk yield and udder traits could be used in an advanced selection program.
