The aim of this study was to determine the factors affecting the Daily Milk Yield (DMY) per milking, Non-fat Dry Matter percentage (NFDM%) and Somatic Cell Count (SCC) from Holstein-Friesian (HF) and Brown-Swiss (BS) cows managed in the Mediterranean climatic conditions in Turkey. The farms considered in this study were visited monthly for two years to measure DMY and to collect milk samples from each cow during morning and evening milkings. A total of 1,415 sets of data from 67 HF and 16 BS cows for each trait were analyzed by using repeated measures. Breed, lactation month, milking time and the interaction between herd and lactation month were found to be statistically significant for all traits (P
