The provision of adequate hospital pen facilities for injured or unwell pigs is a basic welfare requirement that is frequently inadequate in commercial units; evidence-based standards can dramatically reduce prolonged suffering.
Sick or injured pigs left in the main group face additional suffering through competition for resources and bullying. Prompt identification and transfer to appropriately equipped hospital accommodation allows monitoring, treatment, and recovery. However, hospital pens are often an afterthought — overcrowded, poorly bedded, and inadequately ventilated. Investment in hospital pen quality is directly proportional to welfare outcomes for the most vulnerable animals on any unit.
