Safety Summary

✔ Safe: Small amounts of plain corn
⚠ Use caution: High starch; mycotoxin risk in moldy corn
✖ Toxic: Moldy corn

Why

Small amounts of corn are safe for horses and it's used in some commercial feeds. However, corn is very high in starch and relatively low in fiber compared to hay and grass. Whole corn is difficult for horses to digest and should be cracked or rolled. Moldy corn is dangerous — it can contain mycotoxins like fumonisins and aflatoxins that cause serious neurological and liver damage in horses. Fresh, quality corn on the cob as a treat is generally fine.

Portion Guidance

A few corn kernels or a small piece of cob as an occasional treat. Not a dietary staple.

Risks & Symptoms

Moldy corn: fumonisin mycotoxins — severe neurological damage (equine leukoencephalomalacia)
High starch: laminitis risk for susceptible horses
Whole uncracked corn: difficult to digest
