The economic relationship between animal welfare and farm productivity is more complex than often assumed. Research reveals multiple pathways through which better welfare benefits both animals and farmers.
The economics of farm animal welfare are complex and context-dependent, but the business case for higher welfare is strengthening. Welfare problems are not free: lameness causes reduced milk yield and early culling, respiratory disease increases medication costs and mortality, tail biting triggers injury and infection costs, and food safety failures from stressed animals affect product quality. The welfare-productivity alignment is most evident in extreme cases — severely compromised welfare invariably compromises productivity. The relationship is less linear in moderate ranges, where welfare improvement requires investment before productivity benefits materialize. Consumer markets for high-welfare products are growing, creating price premiums that can recoup welfare investment costs. The strongest economic case for welfare improvement is made at the system level — well-designed high-welfare systems outperform poorly designed conventional systems across multiple economic measures.
