Abstract :In this research, heritability and repeatability of service period (SP), calving interval (CI), gestation length (GL), number of insemination per conception (NIPC), first service age (FSA), first calving age (FCA), lactation milk yield (LMY) and lactation length (LL) were estimated using reproductive and productive records in Brown Swiss herd reared at the Konuklar State Farm in Konya. The heritability values for SP, CI, GL, NIPC, FSA, FCA, LMY and LL were 0.074 ± 0.096, 0.131 ± 0.146, 0.053 ± 0.046, 0.331 ± 0.122, 0.766 ± 0.242, 0.214 ± 0.201, 0.107 ± 0.119, and 0.226 ± 0.156 respectively. The repeatability values of CP, CI, GL, NIPC, LMY and LL were determined as 0.089 ± 0.071, 0.103 ± 0.101, 0.151 ± 0.059, 0.143 ± 0.047, 0.188 ± 0.085 and 0.231 ± 0.084 respectively.Keywords : Süt verimi, döl verimi, kalitim derecesi, tekrarlanma derecesi, Esmer sigir.
