Best Phytate Level-Rich Foods for Horses

Ranked by phytate level content among foods safe for horses in the Creature Feast catalog.

Oats per 1-2kg of whole oats Oats contain phytate as their primary phosphorus storage form. While this reduces some mineral absorption, the overall impact is manageable when zinc and copper supplementation accounts for it.

Barley per 1-1.5kg of rolled barley Barley contains phytate levels similar to oats. Processing (rolling or crimping) does not significantly reduce phytate but does improve overall digestibility.

Timothy Hay per 8-10kg daily ration Timothy hay is very low in phytate compared to grains, making forage-based diets naturally lower in anti-nutrient mineral binding. Another reason to keep hay as the dietary foundation.
