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.
