Data of Evaluation of carcass quality, body and pulmonary lesions detected at the abattoir in heavy pigs subjected or not to tail docking https://doi.org/10.1186/s40813-022-00297-4

The aim of the study was to measure the prevalence of pleurisy, bronchopneumonia (enzootic pneumonia like lesions) and lesions on tail and body of heavy pigs subjected or not to tail docking through the inspection in Italian abattoirs. Additionally, the effect of tail docking and season was investigated on carcass quality (weight, % of lean meat, and Protected Designation of Origin (PDO) classification). For this purpose, a total 17.256 carcasses belonging to 171 batches from 103 farms were inspected in an Italian abattoir between 2019 and 2022. Enzootic pneumonia (EP) like lesions were scored according to the Madec and Derrien method, while pleurisy was scored using the Italian Slaughterhouse pleuritic evaluation system (SPES). For the tail and body, the lesions were scored according to Welfare Quality. The lesion score index (LSI) was calculated for each area. Data were analysed using a general linear model (GLM) including tail caudectomy, season and distance of the farm from the abattoir.<br>

本研究旨在通过意大利屠宰场的检查，测定接受或未接受断尾的重型猪中胸膜炎（pleurisy）、支气管肺炎（类地方性肺炎病变）及尾部和躯体病变的患病率；此外，还探究了断尾和季节对胴体质量（体重、瘦肉率百分比及受保护原产地名称（PDO）分类）的影响。为此，2019年至2022年间，在意大利某屠宰场对来自103个农场171批次的总计17.256头胴体（carcass）进行了检查。类地方性肺炎（EP）病变采用Madec-Derrien法评分，胸膜炎则使用意大利屠宰场胸膜炎评估系统（SPES）评分。尾部和躯体病变依据福利质量（Welfare Quality）标准评分，并计算各区域的病变评分指数（LSI）。采用包含断尾术、季节及农场与屠宰场距离的一般线性模型（GLM）对数据进行分析。<br>
