Horse Stereotypy Prevention Through Management

Preventing the development of stereotypic behaviours in horses requires management practices that meet their fundamental behavioural needs from an early age.

Key Facts

Weaning before 4 months significantly increases stereotypy risk compared to later weaning
Isolation from conspecifics during early life is a primary driver of stereotypy development
Horses with restricted forage access develop oral stereotypies at higher rates than those with ad libitum hay
Young horses housed outdoors in social groups rarely develop stereotypies compared to stabled individuals
Once established, stereotypies persist even when management improves, making prevention critical
Stereotypy prevalence in competition horses can exceed 30% due to intensive stabling regimes

Welfare Considerations

Prevention of stereotypic behaviour is far more effective than attempts to manage it once established. The critical period for stereotypy development is early life, when horses are most sensitive to inadequate social and behavioural opportunities. Weaning practice, social housing, forage access, and exercise are the four most modifiable risk factors. Industry norms that prioritise early weaning and individual stabling for management convenience create the conditions in which stereotypies become common. Changing these norms requires education of breeders and owners alongside clear evidence-based guidance.

What You Can Do

Delay weaning to at least 4-6 months and use gradual rather than abrupt separation methods
Ensure young horses have continuous social contact with other horses
Provide ad libitum forage access to young horses to prevent oral stereotypy development
Maximise daily turnout and minimise stabling duration for all horses
Advocate for codes of practice requiring minimum standards for forage access and social housing
