What is the maximum time a horse should go without food?

• A. 1-2 hours
• B. 6-8 hours
• C. 10-12 hours
• D. 3-5 hours

Answer: (D)

Horses need regular access to forage because their digestive system is designed for constant grazing. The stomach continues to produce acid even when the horse isn’t eating, and without something to chew and swallow, that acid can irritate the stomach lining and contribute to ulcers. Chewing also stimulates saliva, which helps buffer the stomach acid and keeps the gut moving smoothly.

Because of this, a practical maximum without forage is about 3-5 hours. Going longer increases the risk of stomach-related issues and can disrupt gut motility, making colic more likely. So, aim to keep roughage available or minimize gaps between meals, and if a longer interval is unavoidable, provide hay or another forage source to bridge the time.
