Study on High-Efficient Utilization of Fodder of Feather Powder

The combination way of physical processing and biological processing was used in this study, i.e. after being superfine ground to the size of micron, feather powder was fodderized with proteolysis. It was discovered that the content of the soluble protein and the solubility of the processed feather powder increased by 3.37 and 3.38 times respectively, the digestive rate of the pepsin increased by 15%, compared with the unprocessed feather powder.
