Research into farm animal cognition reveals sophisticated mental abilities that have important implications for how we understand and protect their welfare.
The cognitive complexity of farm animals has profound welfare implications that go beyond traditional welfare frameworks focused on physical needs. Animals capable of forming meaningful social relationships, experiencing anticipation and disappointment, distinguishing familiar individuals from strangers, and using rudimentary tools deserve welfare standards that account for their mental lives, not just their physical states. A pig that can manipulate a video game experiences boredom in a barren sty not just as unfulfilled movement motivation but as cognitive impoverishment. A cow with a best friend experiences separation not just as isolation but as the loss of a valued social relationship. These findings challenge the adequacy of minimum space and resource standards that take no account of mental welfare requirements.
