The quality of Musculus longissimus pars thoracis in heavier category of Czech Fleckvieh and Montbeliard bulls
Non-significant differences were established when the nutritional and technological beef quality of Czech Fleckvieh and Montbeliard and their reaction to the end of feeding at the different age and different carcass growth intensity were studied.Bulls were fattened until average weight of 656 kg.
