Several systems have been proposed for the overall assessment of animal welfare at the farm level for the purpose of advising farmers or assisting public decision-making. They are generally based on several measures compounded into a single evaluation, using different rules to assemble the information. Here we discuss the different methods used to aggregate welfare measures and their applicability to certification schemes involving welfare. Data obtained on a farm can be (i) analysed by an expert who draws an overall conclusion; (ii) compared with minimal requirements set for each measure; (iii) converted into ranks, which are then summed; or (iv) converted into values or scores compounded in a weighted sum (e.g. TGI35L) or using ad hoc rules. Existing methods used at present (at least when used exclusively) may be insufficiently sensitive or not routinely applicable, or may not reflect the multidimensional nature of welfare and the relative importance of various welfare measures. It is concluded that different methods may be used at different stages of the construction of an overall assessment of animal welfare, depending on the constraints imposed on the aggregation process.
已经提出了一些系统，用于在农场层面进行动物福利的全面评估，目的是为农民提供建议或协助公共决策。这些系统通常基于几种措施综合成一个单一的评估，使用不同的规则来组合信息。在这里，我们讨论了用于汇总福利措施的不同方法及其在涉及福利的认证计划中的适用性。从农场获得的数据可以 (i) 由专家进行分析，得出总体结论；(ii) 与为每个措施设定的最低要求进行比较；(iii) 转换为等级，然后进行求和；或 (iv) 转换为加权和的数值或分数（例如 TGI35L），或使用特定规则。目前使用的现有方法（至少单独使用时）可能不够敏感或不常规适用，或者可能无法反映福利的多维性质和各种福利措施的相对重要性。因此得出结论，根据对汇总过程的限制，不同的方法可以在动物福利全面评估构建的不同阶段使用。
