The invention discloses a drug-carrying compound microsphere and its preparation and application. The drug-carrying compound microsphere is prepared from the following raw materials in mass proportions: 1-2 parts of starch, 0.4-0.6 parts of flavoring agent, sodium alginate 2-3 copies, 0.4-4 copies of antibiotics, and 2-5 copies of calcium chloride. The present invention will focus on changing the way of using antibiotics, control the amount of antibiotics from the source, compound flavoring agent, sodium alginate, calcium chloride and antibiotics, and obtain compound microspheres by drop method and freeze-drying method, which has the advantages of improving the efficiency of antibiotics. Dosing density and uptake rate of diseased fish reduce the residual amount of unused antibiotics in the water body, and achieve the effect of controlling antibiotic pollution in water while ensuring the efficacy of fish diseases, and the raw materials are relatively wide and the cost is low, and the prepared microspheres are environmentally friendly. type. |
