Feed for promoting growth and development of fish larvae and preparation method of feed

Abstract

The invention discloses a feed for promoting growth and development of fish larvae. The feed is characterized by being prepared from the following raw materials in parts by weight: 19-24 parts of rice bran, 23-26 parts of buckwheat bran, 36-38 parts of orange peel powder, 2-3 parts of red jujube peel, 20-22 parts of luffa leaf powder, 18-22 parts of freshwater mussel powder, 50-54 parts of pea protein powder, 4-5 parts of white fungus ultra tiny powder, 0.12-0.14 part of cellulase, 8-9 parts of licorice roots, 0.9-1.1 parts of N-carbamylglutamic acid chelating zinc and manganese methionine. According to the feed disclosed by the invention, carrot powder, a vitamin B1 solution, phosphatidylcholine and hyaluronic acid are stuffed into a honeycomb, so that vitamin granules are prepared; and an enveloping layer is arranged on the outer walls of the vitamin granules, so that the activity of nutrient granules is effectively protected, the digestive function of fish bodies is effectively improved, and the absorption of nutrient substances is promoted.

Description
