Horse Colic - Welfare Implications and Prevention

Colic is the leading cause of premature death in horses and a major cause of acute pain and distress, with multiple types requiring different management approaches and prevention strategies.

Key Facts

Colic is not a single disease but a general term for abdominal pain in horses, with over 70 recognized types
Approximately 10% of horses will experience a colic episode requiring veterinary attention each year
Surgical colic carries significant welfare costs and success rates vary widely depending on the type and delay to surgery
Risk factors include management changes, high grain diets, limited turnout, and dental problems
Simple management changes including increased hay, water access, and turnout reduce colic incidence significantly

Welfare Considerations

Colic causes acute and sometimes severe abdominal pain in horses, with animals unable to communicate their distress except through behavioral signs that owners must recognize promptly. Delayed recognition and treatment worsens outcomes and prolongs suffering. Horses in intensive management with limited grazing, high grain rations, and irregular access to water face elevated colic risk through disruption of normal gut function. The welfare impact of colic extends beyond the acute episode, with recovery from surgical colic requiring weeks of box rest and restricted movement.

What You Can Do

Learn to recognize early signs of colic including pawing, looking at flanks, and reluctance to move
Call a vet immediately if you suspect colic rather than waiting to see if it resolves
Provide horses with ad-libitum hay access, fresh water, and maximum daily turnout to reduce colic risk
Keep management changes gradual, particularly diet changes, to allow gut microbiome adaptation
Maintain regular dental care to ensure horses can properly chew forage and reduce impaction risk
