Stable design profoundly affects horse welfare, with social contact, adequate space, and sensory stimulation all critical factors.
Isolation in traditional loose boxes prevents horses from expressing fundamental social behaviours, causing chronic psychological stress. Stable design that allows visual, auditory, and tactile contact with neighbours reduces stereotypy and stress. Adequate space for lying down, quality bedding, and sufficient forage provision are essential welfare components. Horses stabled for more than 16 hours daily have significantly poorer welfare than those with outdoor turnout. Social housing arrangements should be the norm rather than the exception.
