Heritability (0.08) was evaluated in a model whereas the comparable group was used the interaction between the herd and the control day. The influence of the herd was used as a comparable group and heritability (0.03). The interaction between herds and years of testing was used as a comparable group (0.04 and 0.05). Heritability (0.08) was evaluated in a model a comparable group was used the interaction between the herd and the control day. Phenotypic correlations between milk urea concentration and milking traits: daily quantity of milk, and the content of fat and proteins (P <0.0001). Positive and low phenotypic correlation (0.15) was found between the milk urea concentration and daily milk yield, between the urea concentration and the daily amount of fat (0.10). Between the urea concentration and milk fat content coefficient was (-0.05), between urea concentration and protein content (0.03).
