Disease prevention is both a welfare and economic priority in livestock farming, with effective biosecurity and vaccination programmes substantially reducing animal suffering.
Disease prevention is foundational to good livestock welfare because sick animals suffer, and preventable disease represents a welfare failure. Effective disease prevention combines biosecurity measures that reduce pathogen introduction and spread, vaccination programmes targeting key endemic diseases, good nutritional management that supports immune function, and management practices that reduce stress — itself a major risk factor for disease. The welfare imperative to prevent disease aligns strongly with economic interests, making disease prevention one of the clearest areas where welfare and productivity goals are mutually reinforcing. However, investment in prevention is consistently undervalued relative to treatment in many farming systems.
