The analysis comprised purebred Charolais bull calves (CH) and crossbred bull calves born from Hereford (CH x HE) and Simmental (CH x SI) cows. Body weights and daily gains were measured in subsequent periods of the experiment and the post-slaughter evaluation was carried out. Carcass lean weight and dressing percentage were evaluated, as well as the lean content of five prime cuts. Total weight of the five prime cuts was measured and its share in the half-carcass weight was determined. The rib-eye area was also measured. The CH x SI crossbreds reached significantly higher body weights at weaning, 210-day body weights and weights at finishing, as well as significantly higher daily gains in all the periods. They had the heaviest carcasses and cuts, particularly the round. The share of tenderloin and rump in the carcass was significantly lower in comparison with that of purebred and CH x HE bulls. CH x SI bulls also had a significantly lower share of the shoulder, shank and shin than the other groups, as well as a significantly higher share of the neck than purebred bulls. The purebred bulls had the highest share of the prime cuts and the largest mean rib-eye area.
