    The aim of the study was to assess the effect of the calendar month on the quantity of milk purchased by dairies and to assess the chemical quality of milk based on analysis of its content of protein, fat, casein, and urea, as well as its SCC. Analysis of milk purchased in individual months showed that the most milk was purchased in June and the least in December. Assessment of the chemical composition of raw milk revealed that it contained on average 4.18% fat, 3.23% protein, 2.61% casein, and 222.92 mg/l urea, with a SCC of 246.67 1000/ml. The differences between means for individual months were statistically significant.
