Feed capable of enhancing capacity of fish for resisting virus diseases and preparation method of feed

Abstract

The invention provides a feed capable of enhancing the capacity of fish for resisting virus diseases and a preparation method of the feed. The feed capable of enhancing the capacity of the fish for resisting the virus diseases is prepared from the following components in parts by mass: 30-40 parts of black bean powder, 30-50 parts of rice bran, 25-40 parts of pumpkin powder, 25-35 parts of wheat bran, 5-9 parts of herba portulacae, 4-10 parts of cabbage, 3-7 parts of begonia fimbristipula hance, 10-16 parts of ulva lactuca, 8-12 parts of cymbopogon citratus, 3-5 parts of rheum officinale, 4-5 parts of fineleaf schizonepeta herbs, 3-7 parts of plantain herbs, 6-9 parts of Chinese yam rhizomes, 3-6 parts of wilford granesbill herbs, 5-8 parts of gypsophila oldhamiana, 2-5 parts of Chinese taxillus herbs, 5-7 parts of poria cocos, 3-6 parts of asparagus and 0-3 parts of table salt. The feed disclosed by the invention is prepared through the technologies of drying, mixing, fermenting, granulating and the like. The feed is prepared from purely natural raw materials, safe and environmental-friendly, rich in nutrition, high in palatability and high in applicability, the capacity of the fish for resisting bacteria and viruses is enhanced, and the weight increment rate and the survival rate of the fish are notably increased.

Description

technical field [0001] The invention relates to the technical field of feed preparation, in particular to a feed for improving fish resistance to viral diseases and a preparation method thereof. Background technique [0002] In the process of agricultural industry adjustment, the proportion of freshwater aquaculture is gradually increasing, and aquatic diseases have become an important factor restricting the development of freshwater aquaculture. In the freshwater fish farming industry, the prevention of viral diseases is the main focus, and the treatment is mainly to prevent water pollution by using broad-spectrum disinfectants. With the expansion of the breeding scale, the development and variation of diseases are also increasing. When the existing disinfectant is too much, it will cause excessive drug residue in the freshwater fish, which poses a threat to people's health. Therefore, through research, people add some antiviral drugs to fish feed to improve the antiviral ...

AI Technical Summary

Problems solved by technology

However, most of the existing feeds are added with chemically synthesized drugs, which have large toxic and side effects and low nutrient element content, which is not conducive to the growth of fish, and the palatability is poor, which reduces the feeding ability of fish and has a low weight gain rate.
