Stereotypic behaviors like cribbing and weaving rarely develop in horses managed appropriately from an early age. Understanding how early management decisions affect stereotypy development helps prevent lifetime welfare problems.
Stereotypy development in young horses is almost entirely an iatrogenic condition - caused by management decisions humans make. The confluence of stressors around weaning (sudden maternal separation, often individual housing, reduced roughage, and high grain diets) creates the conditions in which coping behaviors that become stereotypies develop. These behavioral patterns, once established, are remarkably persistent and represent a permanent behavioral welfare cost. The welfare opportunity is entirely in prevention: management decisions around weaning age, social housing, forage access, and diet composition determine whether most horses develop stereotypies or not. There is no technical reason that stereotypies cannot be rare in well-managed horse populations.
