Keratin - Feed Ingredient

Keratin is a structural protein naturally found in hair, hooves, feathers, and the outer layer of skin. It is rich in sulfur-containing amino acids, particularly cysteine, which contribute to its strength and resilience.

In equine nutrition, keratin is sometimes included in supplements intended to support hoof and coat condition. It may be derived from animal byproducts such as feathers, wool, or hooves. Keratin itself is not a common ingredient in base equine feeds and is primarily used in targeted supplements. The benefits depend on the form used and overall dietary amino acid balance.
