The Five Freedoms remain the foundational framework for farm animal welfare but are increasingly supplemented by the Five Domains model.
The Five Freedoms provide a landmark framework for understanding and assessing farm animal welfare that has influenced legislation, farm assurance, and veterinary practice worldwide. The subsequent Five Domains model extends this to explicitly include positive mental states, reflecting the evolution of welfare science toward promoting good experiences rather than merely preventing suffering. Both frameworks remain relevant for guiding welfare improvement in livestock systems.
