An examination was carried out on 60 hybrid pigs (similar share of gilts and barrows), in winter season, from a pig production farm in the Western Pomeranian Voivodeship (Poland). The study involved the offspring of Hypor and PIC337 boars and Danbred sows (Landrace– Yorkshire) which were housed under the same environmental conditions and fed using a balanced feedmixture ad libitum. All the examined pigs (180 individuals)were transported on a truck fromthe farm located 171 km from the abattoir. The animals were grouped in the truck on three levels, in four pens on each level (12 pens × 15 pigs). In the area of the meat plant, the pigs were kept in one lairage pen, in accordance with density standards, with constant access to water, and were not mixed with pigs from other transports. Until the moment of slaughter, the pigs were subjected to 24 h fasting, including 12–13 h lairage.
