Feathers contain 85% – 90% keratin. Keratin is a structure protein which contains proteins needed by animals but it cannot be digested directly. Therefore hydrolysis of keratin is needed to make it digestible.
Are feathers digestible?
Digestibility of feathers
It is almost impossible to degrade feathers in the digestive tract because it is largely composed of the protein (β-) keratin, which is generally indigestible, if it is not processed with physical and chemical modifications e.g., autoclaving.
Are bird feathers edible?
The human body can’t digest feathers, but they are 90% keratin – a protein that’s found in nails and hair – and packed with nutritious amino acids. Kittibanthorn makes feathers edible by breaking down the protein using a process called acid hydrolysis.
Do feathers have nutritional value?
Feathers are rich in protein content called keratin and constitute 7% weight of the live bird, therefore producing a considerable mass which can be converted to valuable meal. Feather meal is also an excellent source of escape protein.

Is it safe to eat chicken with some feathers?

What are the protein of birds feather?
At a microscopic level, feathers are made of a protein called beta-keratin. The same protein also forms the beaks and claws of birds, and the scales and shells of reptiles.
How is feather meal made?
Feather meal is a byproduct of processing poultry; it is made from poultry feathers by partially grinding them under elevated heat and pressure, and then grinding and drying. Although total nitrogen levels are fairly high (up to 12%), the bioavailability of this nitrogen may be low.
Do chicken feathers contain protein?
Chicken feathers contain more than 85% of crude protein, 70% of amino acids, high-value elements, vitamins, and growth factors [4].
What is the difference between blood meal and feather meal?
Feather Meal is slow release while blood meal is a more fast release nitrogen source. We prefer Feather Meal because it is just easier to work with. Blood Meal can be a bit messy, but it’s great if you need nitrogen fast! We also like to mix the two in order to get the slow and quick release.
Do feathers contain calcium?
Feathers contain calcium carbonate, and thus calcium is needed to grow and maintain good feathers.
How do you use feather meal?
