Abstract :Six reproductive traits and two productive were determined and phenotypic parameters were estimated for these eight traits in the Brown Swiss herd reared at the Konuklar State Farın in Konya. The least squares ineans of first service age (FSA), first calving age (FCA), service period (SP), gestation length (GL), calving interval (CI), number of insemination per conception (NIPC), lactation milk yield (LMY) and lactation length (LL) were 623.19± 3.88 days, 943.49 ± 4.42 days, 118.70±6.75 days, 285.92 ±0.83 days, 387.47 ± 2.99 days, 1.533 ± 0.04 number, 6173.48 ± 102.92 kg and 303.85 ± 5.78 days, respectively. The year had a significant effect on FSA, SP, LMY and LL (p < 0.01) Effect of calf sex on GL, CI on CA (p < 0I) , effect of CA on NIPC and LMY (p < 0.05) , effect of lactation number and CA on CI (p<0.01) and effect of gestation number on NIPC (p < 0.05) were found to be significant.
