Hoof wall is composed almost entirely of protein. Proteins consist of amino acids, and a few specific amino acids are essential in forming strong, healthy hooves. Methionine and lysine are two important amino acids that tend to be deficient in horse diets. Without these building blocks, hoof growth is restricted and hoof integrity is likely to be poor.

In addition, a balanced intake of trace minerals is essential for healthy hoof growth. The mineral zinc, for example, is involved specifically with the integrity of skin, hair, and hoof, and is essential in a diet that supports hoof health.
