Stereotypic behaviors like crib-biting, weaving, and box-walking in horses are signs of compromised welfare that, once established, are difficult to eliminate - making prevention through appropriate management essential.
Equine stereotypies are welfare markers: their presence indicates that the horse's behavioral needs are not being met, either currently or historically. The beta-endorphin release during stereotypy performance suggests these behaviors are self-medicating responses to chronic stress - a welfare state the animal manages by creating its own coping mechanism. Physical suppression through anti-crib collars does not improve welfare; it removes a coping behavior without addressing the underlying deficit. Horses with suppressed stereotypies often show other indicators of compromised welfare including increased cortisol and redirected anxious behaviors. The welfare priority is therefore addressing the management factors that drive stereotypy rather than preventing its expression. Industry resistance to acknowledging stereotypy as welfare evidence stems from its association with reducing property value and from traditional normalization of stabling practices that we now know are welfare-compromising.
