Abstract

Background: Tail inspection in the abattoir is a tool to help determine the welfare status of pigs. However, methodologies vary widely. Moreover, meat inspection is moving from palpation and incision towards visual-only (VIS) examination. This study investigated whether a VIS examination was sufficient to detect tail damage compared to handling (HAND), which ensures examination of all aspects of the tail.

Method: The severity of tail skin damage (0 [undamaged] - 4 [partial/full loss of tail]) and presence/absence of bruises was scored using both methods after scalding/dehairing of 5498 pig carcasses.

Results: There was a good relationship between methods when evaluating tail skin damage (sensitivity, 82.48%; specificity, 99.98%; accuracy, 98.98%; correlation ρ = 0.84). The results were similar for the presence of bruises (sensitivity, 74.98%; specificity, 99.09%; accuracy, 89.94%; correlation ρ = 0.79). However, the percentage of tails classified as undamaged was higher using VIS (69.9%) than HAND (63.55%) examination. Conversely, VIS detected fewer mild lesions (score 1 - 13.64%; score 2 - 11.73%) than HAND (score 1 - 15.21%; score 2 - 15.53%). A higher percentage of bruises was detected using HAND than VIS (37.96% vs. 29.03%).

Conclusions: Visual evaluation is a valid alternative to handling evaluation of carcass tail damage and bruising.

两种评分方法在爱尔兰断尾猪死后检验中尾损评估的比较。
背景:屠宰场的尾部检查是帮助确定猪的福利状况的工具。然而,方法差异很大。此外,肉类检查正在从触诊和切口转向仅视觉检查。这项研究调查了与确保检查尾部各个方面的处理(HAND)相比,VIS检查是否足以检测尾部损伤。方法:在对5498头猪胴体进行烫伤/脱毛后,使用这两种方法对尾部皮肤损伤的严重程度(0[未受损]-4[尾部部分/全部丢失])和是否有瘀伤进行评分。结果:评估尾部皮肤损伤的方法之间存在良好的相关性(敏感性,82.48%;特异性,99.98%;准确度,98.98%;相关性ρ=0.84)。对于瘀伤的存在,结果相似(敏感性,74.98%;特异性:99.09%;准确度:89.94%;相关性ρ=0.79)。然而,使用VIS(69.9%)检查被分类为未损坏的尾部的百分比高于HAND(63.55%)检查。相反,VIS检测到的轻度损伤(评分1-13.64%;评分2-11.73%)少于HAND(评分1-15.21%;评分2-15.53%)。使用HAND检测到的瘀伤百分比高于VIS(37.96%对29.03%)。结论:视觉评估是处理评估胴体尾部损伤和瘀伤的有效替代方法。
