Horse Crib-Biting and Stable Vices

Crib-biting and other oral stereotypies in horses are indicators of inadequate management; prevention focuses on environmental enrichment and forage access.

Key Facts

Approximately 4-8% of domestic horses crib-bite, a behaviour where they grasp a fixed surface and inhale air.
Crib-biting is associated with early weaning, insufficient forage, and highly concentrated diets.
Once established, stereotypies are persistent and are considered indicators of a poor early life environment.
Crib-biting does not reliably cause colic, though its relationship with gastrointestinal disease is studied.
Anti-crib collars suppress the behaviour but do not address the underlying motivation and are not recommended as the primary intervention.

Welfare Considerations

Oral stereotypies such as crib-biting develop when horses cannot perform natural grazing behaviours, typically in stabled horses with limited forage and social contact. These behaviours serve as coping mechanisms and, once established, provide stress relief. Attempting to suppress crib-biting without addressing the underlying cause may increase welfare compromise. Management changes — ad libitum hay, increased turnout, reduced concentrate feeding, and social contact — can reduce the frequency even if the behaviour does not disappear entirely. Horses showing stereotypies should not be penalised or sold as "vicious."

What You Can Do

Provide horses with ad libitum forage to reduce the risk of oral stereotypy development.
Maximise daily turnout time and social contact with other horses.
Avoid early or abrupt weaning of foals; allow gradual weaning with social support.
If your horse crib-bites, address management before considering anti-crib devices.
