Problems solved by technology

In the traditional disease prevention and control methods, antibiotics and chemical drugs are used in large quantities as the main means, which leads to the resistance of pathogens and the decline of treatment effect; at the same time, due to the residue of drugs, the health and environmental safety of consumers are seriously affected
Due to the excessive drug residues in aquatic products, the export of products is restricted, which seriously affects the competitiveness of my country's aquatic products, hinders the development of domestic and foreign markets, and causes huge economic losses.

Embodiment Construction

[0010] Take Radix Isatidis, Forsythia, Radix Astragali, Huoxiang, Satawang and Coptis chinensis in equal parts by weight, and the specific preparation process is: raw material → first drying → secondary drying → coarse crushing → superfine crushing → sieving → recombination Mix to make compound Chinese herbal medicine powder.

[0011] Take the culture medium (ingredients: cornstarch 2%, peptone 2.5%, corn steep liquor 1.5%, NaH2PO40.8%; pH7.2-7.4)→sterilization (121°C, 30min)→cooling (30°C)→inoculation (inoculation 5%)→seed tank culture (30°C, 18h)→expanded culture (30°C, 24h)→centrifugation→loading carrier (bran)→drying→crushing to make Bacillus licheniformis composite solid material, the above-mentioned lichen The Bacillus licheniformis flora in the Bacillus composite solid material is 10 9 CFU / g.

[0012] The raw materials obtained above are weighed and mixed evenly in proportions by weight to prepare feed additives for prawns, including 8-12 Chinese herbal medicine powde...

Abstract

The present invention discloses one kind of prawn feed additive. The prawn feed additive is compounded with Chinese herbal medicine powder in 8-12 weight portions and solid lichen-forming bacillus material in 12-18 weight portions. The Chinese herbal medicine powder is prepared with isatis root, forthythia, astragalus root, agastache, Viola yedoensis and Chinese goldthread and through stoving andcrushing. The solid lichen-forming bacillus material contains lichen-forming bacillus in 10<9> CFU / g. The prawn feed additive is added into prawn feed in the added amount of 0.15-0.50 wt% before the feed is pelletized into 1.5 mm size grains. By means of the synergistic effects of the Chinese medicine materials and the lichen-forming bacillus, the prawn feed additive has the functions of raising the activity of digestive enzyme, promoting the growth of prawn and raising the survival rate of prawn.

Description

technical field [0001] The invention relates to a prawn feed additive. technical background [0002] With the rapid development of the shrimp farming industry and the continuous improvement of the degree of intensive farming, the disease problem is becoming more and more serious. In the traditional disease prevention and control methods, antibiotics and chemical drugs are used in large quantities as the main means, which leads to the resistance of pathogens and the decline of treatment effect; at the same time, due to the residue of drugs, the health and environmental safety of consumers are seriously affected. Due to the excessive drug residues in aquatic products, the export of products is restricted, which seriously affects the competitiveness of my country's aquatic products, hinders the development of domestic and foreign markets, and causes huge economic losses. Contents of the invention [0003] The purpose of the present invention is to provide a feed additive for...
