Feather meal is a byproduct of processing poultry; it is made from poultry feathers by partially hydrolyzing 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. Feather meal is used in formulated animal feed and in organic fertilizer.
