这项工作的目的是确定牛从农场到屠宰场的运输对动物福利和宰后肉质量（仪器和感官）的影响。从 2000 年 7 月到 2001 年 7 月，在西班牙萨拉戈萨市当地屠宰场的不同距离处进行了 39 次商业旅行。在农场和宰杀时采集血样，并在宰后 24 小时测量肉的 pH24。胸背最长肌样本取自 48 头屠宰公牛，并进行仪器和感官品质分析。与对照值相比，皮质醇、葡萄糖、CPK、乳酸和 N:L 比率在运输过程中增加。与少于 1 小时或超过 2 小时的旅程相比，1-2 小时的运输后皮质醇更高。一般来说，这些参数表明冬季条件下的压力略大于夏季条件下的压力。通过 Warner-Bratzler 设备测量的肉嫩度表明，运输时间或季节没有显着影响。 24 小时内 pH24 或肉色随运输时间没有显着变化。运输时间对整体喜好有显着影响（p < 0.05），夏季运输的动物肉质稍嫩，整体喜好较高。
The purpose of this work was to determine the effect of transport of cattle from the farm to the abattoir on the animal's welfare and post mortem meat quality (instrumental and sensorial). Thirty-nine commercial journeys were followed in Spain from July 2000 to July 2001 at varying distances from a local abattoir in the city of Zaragoza. Blood samples were taken at the farm and at sticking and meat pH24 was measured at 24 hours post-mortem. Samples from the M. longissimus dorsi thoracis were taken from 48 slaughter bulls and analysed in terms of instrumental and sensorial qualities. Cortisol, glucose, CPK, lactate and N:L ratio increased during transport compared to control values. Cortisol was higher after 1-2 h transport compared to journeys that were less than 1 h or more than 2 h long. In general the parameters indicated slightly more stressful conditions under winter conditions than in the summer. Meat tenderness measured by a Warner-Bratzler device demonstrated that there was no significant effect of either transport time or season. There was no significant change in pH24 or meat colour at 24 h with transport time. Transport time had a significant effect (p < 0.05) on overall liking and animals transported in summer had slightly more tender meat and higher overall liking.
