This study included 292 cows of Simmental breed selected for bull dams on the territory of the Republic of Serbia during one year. Selection of cows for herd of bull dams was done after finalized first and subsequent lactation. In this study, the effect of region and year of calving on milk traits is presented. Applying the method of least squares average value of milk production was obtained - 5,754.49 kg, milk fat content - 3.98% and quantity of milk fat - 230.24 kg. Regions had statistically highly significant effect (P is less than 0.01) on all investigated milk traits. Year of calving showed no statistically significant effect on milk yield, yield of milk fat, and content of milk fat (P is greater than 0.05).
