The study aimed at evaluating the growth and development of heifers (68 animals) and beef performance of bulls (41 animals) representing 4 genetic groups: I cb, II - cb x hf, III - hf, IV - (cb x hf/ x czb) cb = Black-and-White; hf = Holstein-Friesian; czb = Red- and-White. All heifers were maintained on a moderate level of feeding. The semi-intensive fattening of bulls was conducted up to 15 months of age. The highest dailly gain and thus the highest body weight at the age of 15 months was observed in the heifers sired by czb bulls (group IV). Among the bulls the highest daily gain and the largest body weight were achived by the pure cb animals (group I). Animals with a large share of hf blood (group III) were highest at withers. However, thier body width measurements were considerably lower. Beef performace of the progeny of the czb sires was a good one.
