Compensatory growth studies in pigs have indicated that their meat tends to have increased proteolysis and a faster rate of tenderisation (Kristensen et al., 2002). The postmortem rate of muscle glycogen decline influences meat quality, for example in PSE. There are two forms of muscle glycogen, acid soluble macroglycogen (MG) and acid insoluble proglycogen (PG), which have different turnover rates in vivo (Graham et al, 2001). The aim of this study was to determine whether a compensatory growth feeding regime would influence meat quality characteristics and whether the changes in feed availability during the trial would differentially alter the postmortem degradation of the different forms of glycogen.
