The aim of the research was to determine the basic reproductive traits in heifers and Simmental cows, which are grown on the farm of Agricultural good "Rogatica" Borike (RS). In the first part of this study analyzed the indicators for the 35 heifers, the first calving. Heifers are achieved average age at first conception of 18.92 months, or 567.6 days, which represents a satisfactory age at first fertilization. The average age of heifers at first calving was 28.41 months or 852 days. The average duration of first pregnancy rates amounted to 284.72 days. The ratio of male to female calves at first calving was 55.56% male: 44.44% female calves.
