Sumario:SIMPLE SUMMARY: The modern pig meat production chain is increasingly focused on farm biosecurity, animal health, meat quality, and safety. The substantial increase of the global pork meat consumption is associated with many challenges that have impact on world meat markets, such as animal disease outbreaks, sanitary restrictions, and trade regulations and policies. To overcome such challenges and assure more consistent pork meat quality (and safety), there is a need to develop effective and reliable monitoring system in a farm–abattoir continuum. The use of specific biomarkers for proactive assessment of the pig chain characteristics is therefore of importance. Namely, the introduction of new user-friendly methodology, based on selected biomarkers, e.g., stress hormones and inflammation markers (acute phase proteins) may contribute to evaluation of the quality of processes, detection of critical points in the production system, and may anticipate the pork meat traits (quality and safety). In addition, such an approach can also contribute to the better understanding of interrelations between farm biosecurity and animal health versus meat quality and safety and can be used for detection of failures in the pig production system and with potential to be incorporated in certification programs for the pork meat industry. ABSTRACT: The modern pig production chain is increasingly focused on biosecurity, quality, and safety of meat and is associated with many challenges impacting world meat markets, such as animal disease outbreaks and sanitary restrictions, trade regulations and quality requirements. To overcome such challenges and assure more consistent pork meat quality (and safety), there is a need to develop an effective and reliable monitoring system in a farm–abattoir continuum that can be based on selected biomarkers. This study assessed interrelations of selected stress and inflammation biomarkers (acute phase proteins (APP)) between farm biosecurity score versus pork meat quality traits after two different lairage periods. Briefly, the maximum recorded levels of stress hormones (436.2 and 241.2 ng/mL, for cortisol and Chromogranin A (CgA), respectively) and APP (389.4 and 400.9 μg/mL, Pig Major Acute Proteins (MAP) and Haptoglobin (Hp), respectively) at four commercial farms were within the recommended threshold values. Cortisol and APP were negatively correlated to the internal and total biosecurity scores of farms. The increase of level of both sets of biomarkers was found at bleeding (after transportation and lairage period), but with lower values after long (18–20 h) versus short (1–3 h) lairage lay-over time. In general, negative correlation was confirmed between stress and inflammation biomarkers and carcass/meat quality traits. The farm total biosecurity level significantly affected chilling yield, meat temperature, and a* value. Pig-MAP emerged as a good biomarker with a promising potential for assessment and anticipation of broad aspects in the pork meat chain. It can be used for detection of failures in the pig production system and might be incorporated in certification programs for the pork meat industry.
