abstract = "This study assessed the influence of transport conditions on welfare indicators of slaughter
pigs with different health status and RYR-1 genotype. The group of pigs, predominantly consisting of
Nn (56.67%) and subclinically diseased (60.00%) individuals, that were exposed to short transportation (<30 min) at high loading density (~235 kg/m2
) had the highest slipping (p < 0.0001), falling
(p = 0.0009), turning back (p < 0.0001), reluctance to move (p < 0.0001), panting (p < 0.0001) and
shivering (p < 0.0001) frequencies at unloading. Subclinically diseased Nn pigs subjected to short
transportation (<30 min) and high loading density (~235 kg/m2
) had the highest lactate (p < 0.0001
and p < 0.0001), glucose (p = 0.0450 and p = 0.0002), CK (p < 0.0001 and p = 0.0010), LDH (p < 0.0001
and p = 0.0484), AST (p = 0.0208 and p = 0.0170), ALT (p = 0.0500 and p = 0.00081), ceruloplasmin
(p = 0.0334 and p < 0.0001) and MDA (p = 0.0048 and p < 0.0001) concentrations, but the lowest
sodium (p < 0.0001 and p < 0.0001), chloride (p = 0.0001 and p = 0.0432), albumin (p < 0.0090 and
p < 0.0001), PON-1 (p = 0.0122 and p = 0.0500) and GSH (p = 0.0042 and p = 0.0340) levels, respectively. In the group consisting of of stress-resistant (100%) and predominantly healthy (60.00%)
pigs subjected to short transportation (<30 min) at high loading density (~235 kg/m2
), none of the
individuals showed irregular behavioural reactions during unloading. Healthy NN pigs that underwent short transportation (<30 min) at high loading density (~235 kg/m2
) had the lowest lactate
(p < 0.0001 and p < 0.0001), glucose (p = 0.0450 and p = 0.0002), CK (p < 0.0001 and p = 0.0010), LDH
(p < 0.0001 and p = 0.0484) and ceruloplasmin (p = 0.0334 and p < 0.0001) levels, but the highest sodium
(p < 0.0001 and p < 0.0001) and chloride (p = 0.0001 and p = 0.0432) concentrations, respectively. Inconclusion, the most compromised welfare was recorded in subclinically diseased Nn pigs exposed
to short transportation (<30 min) and high loading density (~235 kg/m2
), while under the same
conditions, the welfare of healthy NN pigs was not compromised. Therefore, stress-carrier pigs with
subclinical pathological lesions should not be considered fit for transportation, indicating that the
health status and genotype are the key factors for optimising pig welfare",
