Abstract
The coefficients of heritability 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 – Animal Model. Beside the typical effects, in this model an effect of the level of productivity of a herd and the effect of a region were taken into consideration. The level of the herd had a great impact on the values of the coefficients of heritability.
