Hydrolyzed Feather Meal
A concentrated protein ingredient from poultry feathers, in which the keratin is hydrolyzed to improve protein usability. It is characterised by its cystine and sulfur-containing amino acids. Value depends heavily on the degree of hydrolysis and protein digestibility.
Raw feathers are mostly keratin and difficult to use in native form; hydrolysis improves protein usability. The degree of hydrolysis and the pepsin digestibility vary between products and are the key parameters to confirm. Marine protein and lipid ingredients are covered on the Marine Ingredients page; other animal proteins on the Animal Protein Raw Materials page.

Frequently asked questions.
Why is Feather Meal hydrolyzed?
Raw feathers are mostly keratin, difficult to use in native form. Hydrolysis improves protein usability. The degree of hydrolysis and digestibility vary between products and should be confirmed.
What makes its amino-acid profile distinctive?
It is relatively rich in cystine and sulfur-containing amino acids, but the practical value depends on protein digestibility, which should be confirmed per specification.
How do I request a specification or quotation?
Send an inquiry with intended application, target specification, quantity, destination country, required documents and delivery schedule. Availability and specification are confirmed case by case.
