Abstract. Forty three bulls (13 Holstein, 12 crosses Holstein x Belgium Blue, 9 Slovak Pied and 9 crosses Slovak Pinzgauer x Piemontese) were taken in this experiment. Thirteen were stressed by mixing overnight before slaughter. Muscle values were analysed for glycogen ante mortem (M. semitendinosus), glycogen and pH post mortem (1 h, 3 h, 48 h) from logissimus dorsi. The ante mortem and post mortem (1 h, 3 h) muscle glycogen concentration was depleted (P < 0.01) in all stressed bulls. Differences (P < 0.01) were found also in pH (48 h). Significant correlations (P < 0.01) between ante mortem and post mortem (1 h, 3 h) muscle glycogen respectivelly and ultimate pH supported the possibility to measure of stress and to predict carcass ultimate pH of bulls.
