Pasture quality, management, and access profoundly affect horse welfare through nutrition, exercise opportunity, and social interaction.
Horses denied adequate pasture access suffer both physically and behaviorally. The drive to graze and move continuously is fundamental to equine physiology and psychology. Inadequate turnout drives stereotypies, increases colic risk, and prevents the social interaction horses need for psychological wellbeing. Pasture management must balance the metabolic risks of rich grass with the behavioral welfare benefits of free movement and social grazing.
