The invention provides a feed for improving the disease resistance of sea cucumber, comprising the following components by weight: 50-60 parts of copper algae, 10-15 parts of marine polypeptides, 5-10 parts of defatted fish meal, and 1-2 parts of complex vitamins 1 to 2 parts of complex minerals, and 15 to 25 parts of sea mud. The present invention also provides a method for preparing a feed for improving disease resistance of Apostichopus japonicus, comprising the following steps: (1) preparation of marine polypeptide; (2) preparation of seaweed powder; (3) mixing; (4) granulation . In addition, the present invention also provides the application of a feed for improving the disease resistance of Apostichopus japonicus. The feed prepared by the invention can significantly improve the immune response and disease resistance of Apostichopus japonicus, and the copper algae in the feed can replace the salvia and sargassum commonly used in the sea cucumber feed, which relieves the resources such as salvia The tension promotes the growth of sea cucumber and improves the quality of sea cucumber. |
