The study was aimed at the determination of the impact of the somatic cell count on the milk productivity of different varieties of black and white cattle. The best quality of milk according to the somatic cell count was determined in Lithuanian Black and White cattle (400+45,8 ths./ml). Cows of this breed were less prone to mastitis. The highest number of somatic cells were found in the milk of high productive cows of imported Swedish Black and White (635131,4 ths./ml), Holstein (611126,5 ths./ml) and German Black-and-White breeds (603+31,2 ths./ml). Milk productivity and somatic cell count in Black and White breed were negatively correlated from -0,04 (Dutch Black and White) to 0,23 (German Black and White). So, an increase of somatic cells count has the negative effect on milk productivity of cows (P0,05)
