Abstract
The coefficients of phenotypic correlation based on the milking features dates of 488 990 cows examined between 1975 and 1992 were estimated. The estimation was made in use with AM. The attention was paid especially on the effect of the level of a productive herd. There was observed a great impact of the level of the production on the precision of an estimation. The results of the phenotypic correlation had a very strong flexibility of the estimations obtained.
