In a trial involving 2496 pigs, the effect of transport stocking densities of 201, 241, 281 and 321kg m(-2) on carcass quality and welfare were evaluated. This range encompassed the upper level set for 100kg pigs in European Union legislation (235kg m(-2)). Four farms and two lorries were involved over 16 experimental days with an average journey time of 3hr. Stocking density had no effect on any variables measured. Source farm had a significant effect on ultimate pH, reflectance and electrical conductivity in the m. longissimus dorsi, reflectance in the m. adductor and extent of rigor mortis development in the m. semimembranosus. Overall, the measurements made produced no evidence that transport stocking density had an effect on the carcass quality or welfare of 95kg pigs on short journeys.
在一项涉及2496头猪的试验中，评估了201、241、281和321千克/平方米的运输饲养密度对胴体品质和福利的影响。这个范围涵盖了欧盟法规中为100千克猪设定的上限（235千克/平方米）。在16个试验日里涉及了4个农场和两辆卡车，平均运输时间为3小时。饲养密度对所测量的任何变量均无影响。来源农场对背最长肌的最终pH值、反射率和电导率、内收肌的反射率以及半膜肌尸僵发展程度有显著影响。总体而言，所进行的测量没有证据表明运输饲养密度对短途运输的95千克猪的胴体品质或福利有影响。
