Best Phosphorus-Rich Foods for Horses

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

Oats per kg: approximately 3.5-4g phosphorus Oats are relatively high in phosphorus compared to hay (about 3.5-4g per kg), which is why grain-heavy diets can invert the Ca:P ratio. Balance oat intake with adequate calcium from forage.

Barley per kg: approximately 3-4g phosphorus Barley provides about 3-4g phosphorus per kg. Like oats, it is phosphorus-rich and must be balanced with calcium sources.

Beet pulp per kg dry weight: approximately 0.8-1g phosphorus Beet pulp provides moderate phosphorus at about 0.8-1g per kg dry weight. Its lower phosphorus relative to calcium helps maintain a favorable Ca:P ratio.

Timothy Hay per kg: approximately 2-3g phosphorus Timothy hay provides about 2-3g phosphorus per kilogram. The natural Ca:P ratio of timothy (approximately 1.5-2:1) makes it ideal for maintaining mineral balance.

Sunflower Seeds per 100g: approximately 660mg phosphorus Sunflower seeds are high in phosphorus. Feed in moderation and ensure adequate calcium in the overall diet when including seeds.

Peas per 100g: approximately 108mg phosphorus Peas provide about 108mg phosphorus per 100g. A moderate contributor when included as part of the feed.
