title: [Cyclic AMP level in the muscle tissue of cattle and the physico-chemical properties of meat].
abstract: The purpose of this study was to determine quantitative changes of cyclic adenosine mono-phosphate (c-AMP) level in meat of slaughter bulls. Meat samples were taken from the muscle longissimus dorsi (LD) of bulls overstressed by transport, which were stunned with electricity without rest. The obtained data did not show statistical correlations between c-AMP level and pI-values but showed statistical correlations between c-AMP level and some sensory properties of beef. The highest concentration of c-AMP was detected in the muscle about 90 minutes after slaughter. Individual differences in the concentration of c-AMP in the LD were observed in 30 min. after slaughter. In this time the high c-AMP level was correlated with the colour and sensory properties of meat and bouillon.
