The invention discloses a composite probiotic preparation and its preparation method and application. The composite probiotic preparation includes probiotic powder, squid paste, earthworm extract, thitin dimethyl-β-propionate, soybean oligosaccharide, and spirulina powder. The present invention also provides a method for preparing a composite probiotic preparation: (1) weighing the raw materials and mixing them evenly; (2) placing the mixture in step (1) in a tableting machine, compressing and drying to obtain a composite Probiotics. The present invention also provides the application of the composite probiotic preparation in aquaculture. The composite probiotic bacteria preparation of the invention is natural and pollution-free, and can also induce aquaculture organisms to eat the composite probiotic bacteria preparation through flavor substances to improve the utilization rate of the composite probiotic bacteria preparation. In addition, the composite probiotic preparation of the invention can improve the immune function and intestinal microecological balance of aquaculture organisms, promote the absorption and utilization of nutrients, and improve the utilization rate of aquatic feed. |
