Simple Summary

Transport to the slaughterhouse is a stressful event for pigs. Travel duration and conditions can negatively affect animal welfare and carcass quality. Some defects in fresh hams are strictly connected to pre-slaughter transportation. Journeys with short (<37 km) and long (>170 km) distances may increase damage in fresh hams and decrease Denomination Protected of Origin (DPO) Parma dry-cured ham production.

Abstract

Pre-slaughter handling is related to defects in fresh hams that result in exclusion from the DPO Parma chain, including hematomas, lacerations, microhaemorrhages and veining. To determine the effects of transport conditions on hams, we collected data on defects in 901,990 trimmed fresh hams from heavy pigs provided by 3,650 batches from slaughterhouse during 2012 and 2013. For all batches, transport distance (1–276 km) season and year of delivery were considered. A decrease of all defect occurrences was observed for increasing distance up to 170 km (P < 0.05). Above 170 km, however, all defects frequencies increased (P < 0.05). Season showed an effect on the incidence of defects, with an increasing of hematomas and lacerations in winter and autumn respectively (P < 0.05) and the highest percentage of veining and hemorrhages in spring (P < 0.05). Summer had the lowest incidence of defects on fresh hams. We concluded that the incidence of the examined defects and the subsequent rejection for DPO Parma ham production is lower in fresh hams transported 38–170 km during the summer. View Full-Text
