4. Conclusion
In this paper, a global determination checklist is presented tomap
out the influence of different combinations of critical variables, during
all pre-slaughter phases, on the pork quality and the risk for PSE
meat, measured in the slaughterline. Despite the well-known difficulties
to measure meat quality and large variability in observed
pHLT, this table gives a clear indication of the pHLT and the risk to develop
PSE meat in the investigated process. Furthermore this study
proves also that every stage during the pre-slaughter process has
its impact on the quality of the produced pork and establishes that
the closer to the stunning phase, the more critical the pre-slaughter
handling of the pigs on the pHLT and PSE prevalence of the produced
pork. The checklist is not only useful to predict the pork quality but
also to advice intervention during the pre-slaughter process, in
case during some pre-slaughter phases the handling of pigs is not according
to the defined standards to deliver good pork meat. This
study developed a very useful and upgradable tool for and by the
pork industry, also again showing that the welfare of pigs might
have a big impact on final meat quality, including perception by
consumers.
Further research will focus on the impact of loading aspects, such as
sound levels during loading, loading time etc. on pHLT of pork and the
PSE prevalence, finally to implement also the loading proc
