Feather and down raw material processing and prospects of it usage

Feather and down raw material arouses constant interest in specialists as some additional protein source for animals. Feather protein resistance to heat and fermentation action decreases its usage possibility as feed raw material. Severe heat processing affects essential amino acids content in final product, and insufficient treatment causes loss of protein digestibility. However feather and down raw material processed with short time high temperature hydrolysis results in the product that is characterized with significant protein quantity, high digestibility and availability degree.
