The files with 224 and 234 individual milk samples were collected in the summer and winter for three years. Group 1 had higher genetical value and had even better nutrition according to the MY. The MY was higher by 43% (P<0.001). The studied high MY factor had statistically significant influence (P<0.05 and P < 0.001) on the following milk parameters: fat (FAT), lactose (LAC), solids non fat (SNF), alcohol stability (AL), rennet curds firmnes (RCF), crude protein (CP), casein (CAS), true protein (TP), fat/true protein ratio (F/CP). Selected differences were: FAT (H1 3.68 \u00B1 0.77; H2 3.99 \u00B1 0.93%); CAS (H1 2.50 \u00B1 0.27; H2 2.59 \u00B1 0.29%); TP (H1 2.99 \u00B1 0.30; H2 3.09 \u00B1 0.33%). Other 16 milk parameters (e.g. SCC (H1 289 > 210 103.ml-1 H2), urine, ratio of urea nitrogen in the non protein nitrogen, acetone, pH and rennet curds firmness) were influenced insignificantly (P>0.05)." .
