Abstract: Purpose of the study was a cowshed climatic factors studies assessing the lint between the quality of milk. Investigations were carried out tethered barn. Barn air temperature and relath c humidity with the temperature and humidity gauge - Cox Tracer. Every week during the somatic cell count in milk throughout the year, a study used to DeLaval cell counter DCC. During the cold period in the barn air temperature varied from 8°C to 20 °C. At that time. the relative humidity ranged from 76% to 98%. Humidity in the air above the rate where the temperature was 8°C and eight were missing for 7 days. The highest somatic cell count ir milk (300 thousand/ml) at the end of July - early August (pasture period). During the indoo: period, the highest number of somatic cells in milk (270 thousand/ml) in February, where the outside air temperature, 20°C. Correlation between the barn air temperature and somati: cells has not been established (R2 = 0.0097). However, the decrease in temperature, somatic cell count to grow in the 15 °C - 180 thousand/ml, while the air temperature dropped belov. 10°C - somatic cell count rose to 310 thousand/ml. The relationship between the barn and the relative humidity of somatic cells has not been established (R2 = 0.003)
