Abstract
Somatic cells count (SCC) is a common method of milk quality and udder health status evaluation. Dairy herd of Black-and-White cattle with an average milk yield of ca 10 000 kg per lactation was analysed due to SCC pattern. Significant influence of the year on share of number of test milking with low level of SCC (<40 000 per 1 ml) in cows with low milk yield (<20 kg per day) was stated. Besides, cows with low daily milk yield (<20 kg per day) characterised with higher share of milking with low SCC in the 3-rd lactation when compared to the 1st lactation.
