The invention relates to the technical field of biologics, and in particular relates to a bone glue enzyme hydrolyzed protein feed processed by residues obtained by extracting chondroitin sulfate and a processing method for the bone glue enzyme hydrolyzed protein feed. The invention provides the bone glue enzyme hydrolyzed protein feed processed by the residues obtained by extracting the chondroitin sulfate. The bone glue enzyme hydrolyzed protein feed comprises the following components in percentage by mass: 30-45 percent of polypeptide, 7-11 percent of amino acid, 10-19 percent of coarse fat and 7-15 percent of calcium. The invention further provides a processing technology for the bone glue enzyme hydrolyzed protein feed processed by the residues obtained by extracting the chondroitin sulfate. The processing method comprises the following steps: raw material collection, enzymolysis, isoelectric point adjustment, filtering, drying, smashing, sterilization and packaging. According to the processing method, the safe and nutrition-enriched easily absorbed bone glue enzyme hydrolyzed protein feed product is produced by making full use of the residues obtained by extracting the chondroitin sulfate, so that the environment pollution is alleviated, and the economical benefit is enhanced.
