The objective of the experiment was to determine an extent of phenotypic correlations between the basic fattening performance traits and post-slaughter parameters in the slaughter value assessment of crossbred bulls, produced from Black and White Landrace cows mated by bulls of the beef breeds most frequently used for commercial crossing in Poland. Diverse relationships were determined between the growth rate traits and some slaughter value parameters of the bulls obtained by commercial crossing. The highest correlation coefficient for the weight and meat content of 5 cuts was observed relative to the energy consumption per 1 kg body weight gain of bulls. The weight and fat content of 5 cuts was most highly correlated with the round weight. The weight of 5 cuts turned out to be the most precise indicator of the meat content in 5 prime cuts.
