Provide fresh, clean water at all times. Avoid medications unless they are prescribed by your veterinarian, especially pain-relief drugs, which can cause ulcers. Check hay, bedding, pasture, and environment for potentially toxic substances, such as blister beetles, noxious weeds, and other indigestible foreign matter. Avoid putting feed on the ground, especially in sandy soils. Make dietary and other management changes as gradually as possible.
Horses experiencing changes in environment or workloads are a high risk of intestinal dysfunction.
Pay special attention to animals when transporting them or changing their surroundings, such as at shows. Observe foaling mares pre and postpartum for any signs of colic. Also watch carefully any horse who have had a previous bout with colic. They may be at great risk. Maintain accurate records of management, feeding practices, and health.
