The effect of magnesium (Mg-aspartate-hydrochloride) were tested as a preventive measure against DFD meat in a trial on 15 bulls. A daily dose of 150 mg/kg live weight was applied in form of additive to feed twice a day for the last time in the morning 24 hours before slaughter. Applications of magnesium additive moderately increased magnesium concentrations in the blood of both experimental groups (0.83 and/or 0.91 mmol/l). Cortisol secretion to blood was not however expressively inhibited. A decrease in muscular glycogen was more moderate in experimental animals (by 56-65 %). All bulls showed a great decrease in the content of muscular glycogen to the concentrations of 25-40 micro mol/g as a result of premortal stress. There were no significant differences in the terminal pH value while the proportion of DFD meat was lower in experimental groups. A magnesium additive exhibited only a partial effect with respect to the improvement of meat quality characteristics.
