Understanding and preventing stereotypic behaviors in horses through management and environmental improvement.
Stereotypic behaviors in horses are indicators of welfare compromise that typically originate in management systems that fail to meet fundamental behavioral needs. Horses evolved to graze for 14-16 hours daily in social groups with significant movement — management systems that restrict any of these create the conditions from which stereotypies emerge. Prevention through adequate forage provision, social housing, and daily turnout is effective and straightforward. Using physical devices to prevent stereotypy expression without addressing the underlying cause is a welfare failure that compounds rather than resolves the problem.
