The invention discloses a method and a feed for preparing feed rich in docosahexaenoic acid and beta carotene, and relates to the technical field of feed preparation. The preparation method of the feed rich in docosahexaenoic acid and beta carotene disclosed in the present invention comprises the following steps: a fermentation step: inoculating docosahexaenoic acid-producing bacteria A and beta-carotene-producing bacteria B into the same Fermentation in solid fermentation medium. By adopting the preparation method, a feed rich in both docosahexaenoic acid and β-carotene can be prepared, which avoids the oxidation of β-carotene and docosahexaenoic acid due to long-term drying of liquid culture, and shortens the production time. , saving cost and increasing the content of docosahexaenoic acid and beta carotene. |
