Abstract

The present invention provides a preparation method of a healthy feed for fish. The preparation method comprises the following steps: (1) soybean meal and fine rice bran are crushed, the crushed materials are mixed evenly, and the mixture is sieved to obtain a mixture A; (2) the mixture A, bone meal, compound insect powder, corn peptide brown rice germ powder, animal visceral dry powder, sodium chloride and vitamins are mixed evenly to obtain a mixture B; (3) the mixture B is put into a granulator to granulated; (4) the prepared granules are dried to obtain a mixture C; and (5) the mixture C is added into a vacuum sprayer, honey and astaxanthin liquid are sprayed under a vacuum state, then inert gas is filled, the liquid is pressed into the feed at a pressure condition of 60-120 kPa, and after the treatment, compressed material is discharged to obtain a finished product. The prepared feed for the fish is reasonable in nutrition matching and can improve immunity of the fish, and the preparation method can enable nutrient substances to penetrate deeply into the feed and avoid nutrient loss.

Description

Technical field [0001] The invention relates to the field of aquaculture, in particular to a method for preparing healthy fish feed. technical background [0002] Fish is a common food for Chinese residents and an important source of human protein intake. As for aquatic fish farming, it is necessary to understand the biological characteristics, nutritional requirements and feeding standards of the fish, be familiar with the nutritional characteristics, feeding value and scientific and reasonable processing of various feeds, and be proficient in the combination of feeds in order to bring significant benefits. . At present, most of the fish feed preparation methods are relatively rough, and the raw materials are often mixed to complete, and the nutrients on the surface of the fish feed prepared in this way will be lost after being poured into the water, which is very unfavorable to the nutritional efficiency of the fish feed. Summary of the invention [0003] The technical problem...
