Abstract :This study was carried out to determine milk production traits and their repeatabilities of Brown Swiss herd raised at Çumra Agricultural High school in Konya Province. The least squares means of Lactation Period (LP), Lactation Milk Yield (LMY), Average Daily Milk Yield (ADMY) and Maximum Daily Milk Yield (MDMY) were determined as 266.334.740 days, 2578.7143.230 kg, 9.590.469 kg and 15.190.217 kg respectively. Repeatabilities of LP, LMY, ADMY and MDMY were found as 0.2750.0860, 0.2550.0870, 0.2340.0870 and 0.1720.0880 respectively. The year had a significant effect on LMY (p<0.01), LP, ADMY and MDMY (p<0.05). Effect of Lactation Number on LP (p<0.05), LMY, ADMY and MDMY (p<0.01) and effect of calving season on all traits (p<0.01) were found to be statis-tically significant.Keywords : Esmer inek, Süt verim özellikleri, Tekrarlanma Derecesi
