“…Gosàlvez et al [ 15 ] reported a higher incidence of bruised carcasses in pigs transported in winter and in autumn. Scheeren et al [ 13 ] hypothesize that the greater proportion of skin damage in winter is linked to the tendency of pigs to stand during transportation to avoid making contact with the cold floor and walls of the trailer. Dalla Costa et al [ 25 ] found that pigs were more difficult to handle in winter and need more coercion, which led to more handling-induced bruises.…”

Simple SummaryTransport 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.AbstractPre-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.

“…The effect of the season on pig welfare and carcass quality have been also reported [ 11 , 12 ]. The frequency of skin blemishes, hematomas and blood splashing was shown to increase in winter, probably caused by slips and falls due to slippery icy floor [ 13 , 14 , 15 ].…”

“…As shown in Table 3, the pigs slaughtered in winter had the highest skin lesion score, pH 45 value, and incidence of DFD meat (P <0.05). Over winter, the most important causes for a higher proportion of carcasses with skin lesions are falls and slips at unloading (Correa et al, 2013) and in particular during transportation (Scheeren et al, 2014). In addition, a higher proportion of heavier pigs were slaughtered in winter.…”

The aim of this study was to determine the effects of gender, slaughter weight, stocking density, lairage time and season on carcass and meat quality parameters in a low-input production system. The study was conducted on 400 slaughter pigs (200 barrows and 200 gilts) with live weight of 115.0 ± 4.70 kg. Barrows had higher slaughter and carcass weights, fat thickness and lower meatiness. Heavier pigs had higher hot and cold carcass weights, fat thickness, lower meatiness, and higher incidences of pale, soft and exudative (PSE) and dark, firm and dry (DFD) meat. Low stocking density during transportation increased skin lesion score, pH 45 value and the incidence of DFD meat; while high stocking density decreased pH 45 value and increased T 45 value and the incidence of PSE meat. Long lairaging reduced slaughter weight, carcass weight, dressing percentage and backfat thickness and increased skin lesion score. After overnight lairaging, pH 45 value and the incidence of DFD meat became higher. After short lairaging, the pH 45 value was lower, while the incidence of PSE meat increased. Pigs slaughtered in winter had the highest slaughter weight, backfat thickness, pH 45 value and incidence of DFD, and the lowest meatiness. Pigs slaughtered in summer had the lowest slaughter and carcass weights and pH 45 value, and the highest incidence of PSE meat. In conclusion, gender influenced carcass quality, slaughter weight and lairage time, and season affected carcass and meat quality, while stocking density had an impact on meat quality.

“…Environmental conditions during transport, that also affect skin blemishes and meat quality, include the position of the animal inside the vehicle [6,7]. Pigs located in the front and rear compartments or in the upper and lower decks showed an increased number of carcass skin bruises and a reduced pork quality [8]. Despite several studies on the influence of the environmental conditions during long-distance transports on pig welfare and carcass quality, few studies have investigated these effects during short-distance transports.…”

Simple SummaryTransport duration and thermal conditions can negatively affect pig welfare and carcass quality. The effects of short journeys (30 min) in different thermal-humidity conditions on the body surface temperature of live heavy pigs and carcass skin damage were examined. Body temperature increased with increasing Temperature Humidity Index (THI) class. The highest and lowest body surface temperatures were found in pigs located on the middle and upper decks, respectively. THI class significantly affected skin damage scores, which increased with increasing THI class. Even at relatively low temperatures and THI, the results of this study suggested the need to increase the control of environmental conditions in the truck during short-distance transport of pigs, in order to improve welfare and reduce loss of carcass value.AbstractIn order to evaluate the relationships between deck level, body surface temperature and carcass damages after a short journey (30 min), 10 deliveries of Italian heavy pigs, including a total of 1400 animals from one farm, were examined. Within 5 min after the arrival at the abattoir, the vehicles were unloaded. Environmental temperature and relative humidity were recorded and a Temperature Humidity Index (THI) was calculated. After unloading, maximum temperatures of dorsal and ocular regions were measured by a thermal camera on groups of pigs from each of the unloaded decks. After dehairing, quarters and whole carcasses were evaluated subjectively by a trained operator for skin damage using a four-point scale. On the basis of THI at unloading, deliveries were grouped into three classes. Data of body surface temperature and skin damage score were analysed in a model including THI class, deck level and their interaction. Regardless of pig location in the truck, the maximum temperature of the dorsal and ocular regions increased with increasing THI class. Within each THI class, the highest and lowest body surface temperatures were found in pigs located on the middle and upper decks, respectively. Only THI class was found to affect the skin damage score (p < 0.05), which increased on quarters and whole carcasses with increasing THI class. The results of this study on short-distance transport of Italian heavy pigs highlighted the need to control and ameliorate the environmental conditions in the trucks, even at relatively low temperature and THI, in order to improve welfare and reduce loss of carcass value.
