Horses are highly social animals that suffer significant welfare harm when isolated from conspecifics - understanding their social needs guides better stable and pasture management practices.
Horse social welfare is frequently compromised by management systems designed for human convenience rather than equine social needs. Traditional individual stabling without social contact causes chronic stress and promotes stereotypic behaviour development. Modern welfare-conscious stable design incorporates physical contact opportunities between horses through openings or bars. Turnout in compatible groups provides optimal social welfare when space and management allow. Horses in isolation before competition show elevated stress responses that affect performance as well as welfare. Social management is one of the most significant welfare variables under human control and deserves explicit attention in all horse husbandry planning.
