Abstract

The invention discloses an antibiotic complex aquatic feed additive which is prepared from the following components in percentage by weight: 1-2 percent of probiotics, 8-9 percent of prebiotics and 20-30 percent of carriers. The probiotics comprise natto bacillus, bacillus coagulans and clostridium freeze-dried powder, the prebiotics comprise xylo-oligosaccharide, ganoderma meat amylase and oligochitosan, and the carriers comprise montmorillonite and corn starch. The antibiotic complex aquatic feed additive not only has the advantages of stable thalli and long survival time, but also has the effectiveness of united multiple roles. the invention also provides a mixed feed containing the antibiotic complex aquatic feed additive, which can obviously improve the digestion function of animals, increase the growth performance of animals of fishes, shrimps, soft-shelled turtles, and the like, decrease the feed factor, enhance the immunity of the animals and obviously improve the meat quality of animals.

Description

technical field [0001] The invention relates to an aquatic feed additive, in particular to a synbiotic composite aquatic feed additive containing probiotics, prebiotics and carriers and a mixed feed thereof. Background technique [0002] Fishery antibiotics have obvious effects in promoting the growth of aquatic animals, preventing diseases, improving bait coefficient, and ensuring health, which greatly improves the economic benefits of aquaculture. However, the long-term use and abuse of antibiotics has brought various adverse consequences such as drug resistance, drug residues, microecological imbalance, and decreased immunity of animals, which will seriously affect the safety of aquatic products and human health. At present, many countries in the world are gradually adopting measures to prohibit or restrict the use of chemically synthesized drug additives such as antibiotics, so as to ensure the sustainable development of aquaculture. Therefore, it is imminent to researc...
