We observed subsequent results in dairy cows of 55 822 Slovak Simmental cattle. Data were analysed using the SAS and linear model with fixed effects of herd, years and months controls, sire, breeding type. The results of somatic cells count during the years 2009 and 2013 were as follows: the highest number of samples was analysed during 2010 (n = 288 215), where the average count was 560.48*10 3 · ml -1 . The lowest average value of somatic cells count was of amount of 535.93*10 3 · ml -1 (n = 280 732) in 2009.The linear model represents coefficient determination R 2 = 0.038296 % (P<0.001) for SCC with all fixed effects. According to the analyses by the effects on SCC the highest effect was the effect of herd R 2 = 0.021625, then effect of sire R 2 = 0.015075. These effects were highly statistically significant (P<0.001). Correlation coefficients among milk in kg, fat, protein in % with somatic cells count were r = -0.12918, r = 0.04166 and r = 0.11423. These coefficients were highly statistically significant (P<0.001).
