Abstract
The aim of this study was to determine the diagnostic value of glycolityc and energetical quantities on selected meat quality characteristics of Duroc fatteners. A total of 40 Duroc porkers were investigated. Among two analysed sets of determinants (R1 with glycogen and R1 with lactate) measured in 45 min after slaughter, the best diagnostic value for meat quality characteristics exhibit a set involving R1 and glycogen that composed determination coefficient (RC2) was 0.66 for pH measured in 45 min up to 144 h post mortem. Also, with currently used meat diagnostic methods the most useful one that explains the glycolytic and energetic quantities in the highest degree is method that exploits 5 determinants, i.e. pH1, pH24, EC2, EC24 and L*24. Higher composed determination coefficient and canonical correlation (CR) for this method was obtained for set involving R1 and lactate – 0.41 and 0.64** respectively.
