Traditional horse stable design — individual stalls with limited visual and social contact — causes behavioral welfare problems that open-sided, social housing designs substantially reduce.
Stable design has profound welfare implications that are often invisible because the welfare effects are chronic rather than acute. A horse that develops cribbing or weaving after years of stall confinement has been accumulating behavioral frustration in an environment that denied its social and movement needs. Open stable designs — allowing visual, olfactory, and ideally physical contact between horses — reduce social isolation welfare costs within commercial housing. Combined with adequate turnout, social group management, and continuous forage access, evidence-based stable design represents welfare improvement achievable within existing horse-keeping infrastructure.
