In this study, 4589 milk yield records of Holstein cows raised in 389 farms located in Kirsehir Cattle Breeders Association between 2007-2017 were used. Of milk yield characteristics, 305 days of milk yield (DMY), lactation lenght (LL) and dry period (DP), and effects of calving year, parity, calving season, calving age and farm size on these factors were determined. In present study, the overall mean of 305 DMY, LL and DP were calculated as 7350.5 ± 30.70 kg, 398.2 ± 1.61 days and 62.5 ± 17.02 days, respectively. Effects of calving year, parity, calving season and farm size on 305 DMY and LL were statically important (p[removed]0.05), but effects of parity and calving season on its were not important. 305 DMY were increased and phenotypic trend was calculated 62.6 kg for years and statistically significant. To conclude, milk yield traits calculated for Hostein cows raised in Kirsehir. © 2019 Namik Kemal University - Agricultural Faculty. All rights reserved.
