Equine Colic Prevention: Welfare Through Husbandry and Nutrition

Colic is the leading cause of death in horses and a major source of suffering. Evidence-based husbandry practices significantly reduce risk, yet many management factors that increase colic risk remain common.

Key Facts

Colic - abdominal pain in horses - accounts for approximately 30% of all equine deaths
The equine digestive system is highly sensitive to changes in diet, exercise patterns, and stress
Stabled horses with limited turnout have significantly higher colic risk than horses with extensive grazing access
Sudden diet changes are a major colic trigger - transitions to new forage or concentrate should take 10-14 days minimum
Sand colic occurs when horses ingest sand with grazing, accumulating in the large intestine
Dehydration increases colic risk substantially - adequate water access and salt supplementation encourage drinking
Horses with limited foraging time develop hindgut acidosis and increased ulcer risk that predisposes to colic
Parasitic larval migration can damage intestinal blood vessels, causing devitalizing infarctive colic

Welfare Considerations

Colic represents one of the clearest cases where evidence-based husbandry directly prevents animal suffering. Many of the risk factors - abrupt diet changes, limited turnout, insufficient forage, inadequate water - reflect management choices that can be changed. Horses evolved as continuous grazers covering large distances, and housing systems that approximate this more closely - extended turnout, ad libitum hay, appropriate exercise - consistently show lower colic incidence. Prevention is not only more humane but significantly cheaper than treatment. Horse owners and managers who understand the digestive physiology of horses are better positioned to make welfare-positive decisions.

What You Can Do

Provide horses with maximum possible turnout and continuous access to appropriate forage
Transition between feed types gradually over 10-14 days minimum to avoid digestive disruption
Ensure fresh water is always available and encourage drinking with appropriate salt supplementation
Establish a regular worming program based on fecal egg counts to minimize parasitic damage
