“…The way in which pigs react to pre-slaughter stress depends on factors such as handling during loading and unloading, mixing pigs from different pens, stocking density, time of transportation and lairaging, feed and water deprivation, and the season of slaughter (Dalla Costa et al, 2007, Karabasil et al, 2013a2013b). Intense stress immediately prior to slaughter, provoked by inadequate treatment, depletes muscle glycogen, and contributes to rapid glycolysis, with increased lactic acid production early post mortem.…”

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.

“…Several practices, prior to slaughter, are associated with the occurrence of skin lesions on pig carcass, PSE and DFD meat, such as, facility design, handling during loading or unloading of pigs on or from the transport vehicle, fi ghting between pigs after mixing unfamiliar animals, the fl oor type in the transport vehicle, the stocking density and time of transportation and lairaging, the duration of total fasting time before slaughter and season [5,7,8,4,9]. Guàrdia et al [10] found that high stocking density during transport represents a risk for occurring of PSE pork meat.…”

The aim of this study was to determine the effect of gender, stocking density in the transport vehicle, lairage time and season on the incidence of skin lesions on pig carcasses and PSE and DFD meat. Skin lesions on carcasses (480, in total) were assessed according to the Welfare Quality® protocol (2009). The pH and temperature measurements were performed 45 minutes after slaughter. The group of carcasses with skin lesions score 2 had signifi cantly higher incidence of PSE and DFD meat compared to the groups of carcasses with skin lesions score 0 and 1. With regard to gender, there were no differences in meat quality parameters, as well as for the incidence of skin lesions and PSE and DFD meat. The results showed that a space allowance lower than 0.3 m 2 /100 kg and higher than 0.5 m 2 /100 kg pig had a detrimental effect to animal welfare and meat quality. Lairage time affected meat quality parameters, incidence of skin lesions score and PSE and DFD meat, where after long lairaging (> 17 h) mean pH 45 and t 45 values became signifi cantly higher, as well as the incidence of skin lesions and DFD meat. After short lairaging (< 1 h) mean pH 45 value became signifi cantly lower, while mean t 45 value and the incidence of PSE meat became signifi cantly higher. A signifi cantly higher number of skin lesions on the carcass were observed in winter compared to all other seasons. High temperatures during summer and low temperatures during winter had a negative infl uence on meat quality parameters and incidence of PSE and DFD meat.
