A pluralist approach to farm animal welfare, combining animal welfare legislation with market-driven initiatives, has developed in many countries. To enable cross-country comparisons of pig welfare, a number of welfare dimensions, covering the features typically modified in legislative and market-driven welfare initiatives aimed at pig production, were defined. Five academic welfare experts valued the different welfare states within each dimension on a 0–10 scale, then assessed the relative contribution of each dimension to overall welfare on a 1–5 scale. By combining these values and weights with an inventory of pig welfare initiatives in five countries, the additional welfare generated by each initiative was calculated. Together with information on the national coverage of each initiative, the Benchmark value for each country’s production and consumption of pork could be calculated on a scale from 0 to 100. Two (Sweden and the UK) had a much higher Benchmark value than the rest. However, there was a drop in the Benchmark for consumption in Sweden and the UK (indicating imports from countries with lower-Benchmark values for production). Even though the experts differed in the values and weights ascribed to different initiatives, they were largely in agreement in their ranking of the countries.

基准农场动物福利-一种用于生猪生产和猪肉消费的跨国比较新工具。

在许多国家，已经发展了一种将农场动物福利与动物福利立法与市场驱动型举措相结合的多元化方法。为了能够进行全国范围内的生猪福利比较，定义了许多福利维度，涵盖了针对生猪生产的立法和市场驱动型福利计划中通常修改的功能。五名学术福利专家以0-10的等级对每个维度内的不同福利状态进行了评估，然后以1-5的规模评估了每个维度对整体福利的相对贡献。通过将这些值和权重与五个国家的猪福利计划清单相结合，可以计算出每个计划所产生的额外福利。连同有关每个计划在全国范围内的信息，每个国家猪肉生产和消费的基准值可以在0到100的范围内计算。两个国家（瑞典和英国）的基准值远高于其他国家。但是，瑞典和英国的消费基准有所下降（表明从生产基准值较低的国家进口）。尽管专家在不同倡议上的价值观和权重有所不同，但他们在国家排名方面基本上是一致的。
