Applying farm animal cognition research to welfare design and management creates environments and procedures that respect the cognitive complexity of farmed species.
The cognitive complexity documented in farm animals has direct welfare implications for how we design systems, perform procedures, and interact with these species. Pigs with numerical cognition experience richer mental lives; chickens capable of empathic responses suffer more from observed distress in their flock-mates; cattle with long-term social memory experience disruption of familiar relationships as a genuine welfare loss. Designing management systems that respect cognitive complexity — maintaining stable social groups, avoiding unnecessary cognitive disruption — provides welfare benefit proportional to the richness of the mental lives being protected.
