Abstract. The aim of this study was to investigate the influence of sire's lineage on live body growth, movement in open-field arena and time of acrossing the maze of heifers. 54 Holstein heifers, which descended from 7 sires, were used. The highest growth from the birth to 21 months was found in the progeny of sire D, the lowest growth in daughters of sire line B (0.74 ± 0.05 kg vs. 0.62 ± 0.08 kg; P < 0.01). Number of crossed squares in open-field tests did not vary significantly among sire lines. Significant differences were found among sires in the time across of the maze (P < 0.01). Daughters after F and E sires solved the maze more quickly then the others. We found significant relationships between a number of crossed squares during 5 minute open-field test and daily weight gains from the birth to the 6th month of life (r = 0.3712** at the age of 16 weeks and r = 0.3792** at the age of 18 months). Under consideration of the low number of animals analyses showed, that sire's lineage has impact on the growth and maze behaviour.
