Results of production traits obtained from first calving cows and evaluation of the breeding value of bull sires of Simmental breed in Serbia. Data was analyzed using the method of least squares and for evaluation of bulls' breeding value mixed model of random sire effect (BLUP method). Based on obtained results it was established in statistical analysis that breeding region had highly significantly affected (P lt 0.01) the deviation of production traits from the general average. Considerable deviation from the general average was caused by the year and season of calving (P lt 0.05), and interaction of breeding region and calving season contributed to high variation in yield of milk and milk fat (P lt 0.01).U radu su prikazani rezultati koj...
