Evidence-based analysis identifies the most effective interventions for improving farm animal welfare, helping advocates direct their efforts for maximum impact.
The scale of farm animal welfare problems means that the most effective interventions focus on the largest populations experiencing the worst conditions. Evidence-based prioritisation suggests focusing on commercial egg and broiler chicken production, which affect the greatest numbers, and on fish welfare, where welfare protections are virtually absent. Campaigns that change institutional purchasing — by food companies, hospitals, and universities — reach far more animals than campaigns targeting individual consumer behaviour.
