Benchmarking of anatomopathological lesions assessed at slaughter and their association with tail lesions and carcass traits in heavy pigs

Recording lesions at the abattoir provides information for benchmarking pig health and welfare conditions. The study involved 79 batches of Italian heavy pigs, mainly tail-docked. aim was to identify prevalence anatomopathological relationships with carcass traits. scoring enzootic pneumonia-like (EP), chronic pleuritis (CP), dorso-caudal pleuritis, white spots on liver tail (TLs) carried out. Relationships among lesions, season slaughter, slaughtering age traits were tested using logistic regression. Enzootic observed 30.20% (±14.94) lungs an average score 0.91 (±0.77). CP 38.07% (±15.86) 0.83 (±0.34) A. pleuropneumoniae index (APPI) 0.71 (±0.39). pericarditis peritonitis 5.5% (±3.73) 1.09% (±0.64), respectively. White showed a 12.94% (±23.60) 0.02 (±0.04). TLs 34.08% (±11.21); 29.64% (±11.21) moderate damage, 4.44% (±5.02) severe not associated pulmonary or Dorso-caudal suggestive previous Actinobacillus infection, remained similar strongly higher lean meat percentage. Additional studies are necessary better understand this association. results that preventive measures against deemed reduce improve value.HighlightsCardiopulmonary indicative poor loss profit in pork chain could share common risk factors;Dorso-caudal pneumoniae traits;Tail lung Both can factors but have different aetiologies.
