Abstract: The processed product of feather powder was the main protein material in feed industry at present. The aims of paper were to promot the processing and utilization of feather powder so as to improve the nutritive value of product. Combined with practical processing technology was discussed in large and middle enterprises, the processing technology, including the hydrolysis method under high temperature and high-pressure, the enzymatic hydrolysis-hydrolysis method and the bio-fermentation method were introduced containing production process, the process conditions and the quality of product. The conclusion could be made that the biofermentation method was an ideal processing technology for feather powder product.
