Robust biosecurity on pig farms prevents disease outbreaks that cause mass suffering and mortality, making it a core animal welfare priority.
Disease outbreaks on pig farms cause massive welfare crises - illness, death, and emergency culling methods that may not be humane. Prevention through biosecurity is both the most cost-effective and welfare-beneficial approach. However, biosecurity measures like isolation, restricted socialization, and intensive indoor housing must be balanced against behavioral welfare needs. Enrichment and social grouping compatible with biosecurity requirements are achievable.
