Scientific research has revealed that sheep possess sophisticated cognitive abilities including facial recognition, emotional processing, and long-term memory, challenging stereotypes and raising questions about their welfare needs.
The cognitive sophistication of sheep has significant welfare implications for how we manage them in both farming and research contexts. Animals capable of recognizing individuals, forming preferences, and experiencing social stress have more complex welfare needs than previously recognized. Social isolation causes significant stress in sheep, making group housing important for welfare. The disruption of established social groups through mixing at markets and abattoirs causes measurable stress. These findings support welfare standards that maintain stable social groups and provide enriched environments.
