Abstract：
Osteomyelitis is the leading cause of total carcass condemnation in finishing pigs in Portugal, causing significant economic losses in swine production. The present study sought to determine a possible link between osteomyelitis in pig carcasses, pre-slaughter factors, and concomitant post-mortem inspection findings. For this purpose, meat inspection data were collected from 100,489 finishing pigs slaughtered in a northern Portuguese abattoir. Information regarding total carcass condemnation, slaughter season, origin, sex, tail-biting lesions, and husbandry invasive procedures (tail docking and teeth resection) was collected. The main cause of total carcass condemnation was osteomyelitis (61.03%). A total of 36.16% of osteomyelitis cases were present in the anterior region and 52.20% in the posterior region. In the anterior region, 94.78% of osteomyelitis cases were in the mandibular bone. Pigs with clipped teeth and carcasses with pleurisies were associated with a higher occurrence of osteomyelitis (p = 0.00262 and p < 0.0001, respectively). Second- and third-grade tail-biting lesions were also linked to a higher occurrence of osteomyelitis (p = 0.00128 and p < 0.0001, respectively). Slaughter inspection and monitoring procedures should be revised to better assess welfare factors and correlate management practices with the occurrence of osteomyelitis in pig carcasses.
摘要：
骨髓炎是葡萄牙育肥猪尸体完全受到谴责的主要原因，对养猪生产造成重大经济损失。本研究试图确定猪尸体骨髓炎之间的可能联系，屠宰前因素,以及随之而来的验尸结果。为此,肉类检验数据是从葡萄牙北部屠宰场屠宰的100,489头肥猪中收集的。关于尸体总谴责的信息，屠宰季节,origin,性别,咬尾损伤,和畜牧业侵入性程序（尾部对接和牙齿切除）被收集。全部car体谴责的主要原因是骨髓炎（61.03%）。骨髓炎病例的总数为36.16％存在于前部区域，52.20％存在于后部区域。在前部区域，94.78%的骨髓炎病例发生在下颌骨。牙齿夹断的猪和胸膜的尸体与骨髓炎的发生率较高（分别为p=0.00262和p<0.0001）。二级和三级咬尾病变也与骨髓炎的发生率较高有关（分别为p=0.00128和p<0.0001）。应修订屠宰检查和监测程序，以更好地评估福利因素，并将管理实践与猪尸体骨髓炎的发生联系起来。
