We hypothesized that transportation might impact beef sensory quality, particularly as the distance between farms and the slaughterhouse increases. Specifically, we expected that pre-slaughter transport over longer distances would induce stress in the cattle, resulting in elevated ultimate pH and, consequently, reduced beef quality. Thus, this study aimed to specifically study the effects of transport in commercial conditions of Limousin cows from farms located in different areas of France to slaughter on ultimate pH (pHu) measured in the muscle (LT), marbling (two major factors affecting eating quality) and the MSA Index (a global indicator of potential eating quality at the carcass level). Cattle were studied according to distance (<50 km; between 50 and 150 km; and between 150 and 250 km from the slaughterhouse) and according to transport time from the farm to the slaughterhouse (divided into short, moderate, and extended). We found that neither distance nor transport time significantly affected pHu of beef and the other studied parameters (cold carcass weight, meat color, MSA Marbling and MSA Index). Consequently, in our commercial conditions, we concluded that the effects of transport on beef carcasses and beef eating quality of Limousin cows are negligible.
我们假设运输可能会影响牛肉的感官品质,尤其是随着农场与屠宰场之间距离的增加。具体而言,我们预计屠宰前较长距离的运输会使牛产生应激反应,导致最终pH值升高,进而降低牛肉品质。因此,本研究旨在专门研究在商业条件下,将位于法国不同地区农场的利木赞牛运输至屠宰场对肌肉中测量的最终pH值(pHu)、大理石花纹(影响食用品质的两个主要因素)以及MSA指数(胴体水平潜在食用品质的综合指标)的影响。根据距离(距离屠宰场<50公里;50至150公里之间;以及150至250公里之间)和从农场到屠宰场的运输时间(分为短、中、长)对牛进行研究。我们发现,距离和运输时间均未对牛肉的pHu以及其他研究参数(冷胴体重、肉色、MSA大理石花纹和MSA指数)产生显著影响。因此,在我们的商业条件下,我们得出结论,运输对利木赞牛牛肉胴体和牛肉食用品质的影响可忽略不计。
