Animal welfare has become an important subject of public, economic and political concern, leading to the need to validate indicators that are feasible to use at abattoirs. A systematic review was carried out, which identified 72 cattle welfare indicators (CWI) that were classified into four categories (physiological, morphometric, behavioral and meat quality). Their validity and feasibility for use in abattoirs were evaluated as potential measures of cattle welfare during transportation to the abattoir and at the abattoir itself. Several highly valid indicators were identified that are useful to assess welfare at abattoirs, including body condition score, human-animal interactions, vocalizations, falling, carcass bruising, and meat pH. In addition, some intermediate valid indicators are useful and should be investigated further. Information along the food chain could be used systematically to provide a basis for a more-risk-based meat inspection. An integrated system based on the use of key indicators defined for each inspection step with the setting of alarm thresholds could be implemented.

动物福利已成为公众，经济和政治关注的重要课题，导致需要验证可在屠宰场使用的可行指标。进行了系统的审查，确定了72个牛的福利指标（CWI），这些指标分为四个类别（生理，形态，行为和肉质）。他们在屠宰场中使用的有效性和可行性被评估为运输到屠宰场期间和屠宰场本身对牛福利的潜在衡量标准。确定了几个有效的指标，这些指标可用于评估屠宰场的福利，包括身体状况评分，人与动物的相互作用，发声，跌落，bru体瘀伤和肉的pH值。此外，一些中间有效指标是有用的，应进一步研究。可以系统地使用食物链上的信息来为基于更高风险的肉类检验提供基础。可以实施一个基于为每个检查步骤定义的关键指标并设置警报阈值的集成系统。
