扩大肉类检验过程，纳入动物福利的测量，可能有助于显着改善猪（猪）的福利和农场的盈利能力。本研究旨在确定不同福利相关病变的胴体上的患病率及其与胴体重（CW）和胴体重（CC）的关系。还估计了与福利病变相关的CC和CW减少相关的损失的财务影响。收集了3，537头屠宰猪（平均[+/- SEM]胴体重：79.2 [+/- 8.82] kg）的尾部病变、腰部瘀伤和滑囊炎、CW和报废/修剪结果（和相关重量）数据。总体而言，72.5%的猪有可检测到的尾部病变，而16.0%和44.0%分别受到严重腰部瘀伤和后肢滑囊炎的影响。有2.5%的研究尸体被谴责，另有3.3%被修剪。CC的主要原因是过度分泌。虽然尾部病变的严重程度并没有增加复发的风险，但它与CC显著相关。雄性猪的尾部病变和CC的风险较高。与CC和切边相关的生产者经济损失估计为（原文如此）每头研究猪1.10欧元。在严重尾部病变的情况下，CW最多减少12 kg。然而，即使是轻度病变也会导致CW显著降低1.2 kg。与尾部病变相关的潜在CW损失值为（原文如此）每头研究猪0.59。结合可归因于CC和修剪的损失，这代表了在研究时可归因于咬尾的每头猪利润率的43%的损失。这些发现说明了咬尾对猪福利和养猪业盈利能力的影响程度。他们还强调，在肉类检查中纳入福利参数可能会为生猪生产者提供牛群健康和福利管理计划的信息。
Expansion of the meat inspection process to incorporate animal-based welfare measurements could contribute towards significant improvements in pig (Sus scrofa domesticus) welfare and farm profitability. This study aimed to determine the prevalence of different welfare-related lesions on the carcase and their relationship with carcase condemnations (CC) and carcase weight (CW). The financial implications of losses associated with CC and CW reductions related to the welfare lesions were also estimated. Data on tail lesions, loin bruising and bursitis, CW and condemnation/trimming outcome (and associated weights) were collected for 3,537 slaughter pigs (mean [+/- SEM] carcase weight: 79.2 [+/- 8.82] kg). Overall, 72.5% of pigs had detectable tail lesions, whilst 16.0 and 44.0% were affected by severe loin bruising and hind limb bursitis, respectively. There were 2.5% of study carcases condemned and a further 3.3% were trimmed. The primary cause of CC was abscessation. While tail lesion severity did not increase the risk of abscessation, it was significantly associated with CC. Male pigs had a higher risk of tail lesions and of CC. The financial loss to producers associated with CC and trimmings was estimated at (sic) 1.10 per study pig. CW was reduced by up to 12 kg in cases of severe tail lesions. However, even mild lesions were associated with a significant reduction in CW of 1.2 kg. The value of the loss in potential CW associated with tail lesions was (sic) 0.59 per study pig. Combined with losses attributable to CC and trimmings this represented a loss of 43% of the profit margin per pig, at the time of the study, attributable to tail biting. These findings illustrate the magnitude of the impact of tail biting on pig welfare and on profitability of the pig industry. They also emphasise the potential contribution that the inclusion of welfare parameters at meat inspection could make to pig producers in informing herd health and welfare management plans.
