Powder prepared from radix codonopsis and radix astragali and preparation method of powder

Abstract

The invention discloses powder prepared from radix codonopsis and radix astragali. A preparation method of the powder comprises the following steps: (1) mixing radix codonopsis decoction pieces and radix astragali decoction pieces at the mass ratio of 1 to 4, adding 8 times amount of water, soaking, decocting, performing backflow, filtering, and collecting filter residues and filtrates separately;(2) adding 8 times amount of water into the filter residues prepared in the step (1), decocting, performing backflow, filtering and collecting filter residues and filtrates separately; (3) adding 8 times amount of water into the filter residues prepared in the step (2), decocting, performing backflow, filtering, and collecting filter residues and filtrates separately; and (4) combining the filtrates prepared in the steps (1), (2) and (3), performing vacuum concentration to obtain a concentrated solution, and then performing spray drying to obtain the powder prepared from radix codonopsis andradix astragali. The powder prepared from radix codonopsis and radix astragali is used for preventing immunosuppressive diseases and adjusting animal immunity in the clinical practice, makes animal healthy, reduces the occurrence of diseases and the usage amount of antibiotics, and has good economic benefits and ecological benefits.

Description

technical field [0001] The invention relates to the technical field of feed additives, in particular to an extract obtained by decocting Codonopsis pilosula and Radix Astragali as raw materials and a preparation method thereof. Background technique [0002] Since the 1940s, the application of chemically synthesized drugs and antibiotics has led to the rapid development of animal husbandry. As consumers' awareness of environmental protection and health awareness increases, the sales of meat products with drug residues are obviously hindered, and the economic interests of the breeding industry are threatened. The aquaculture industry is facing the upgrading and adjustment of industrial structure, and is developing towards green ecological aquaculture. [0003] With the development of animal husbandry, livestock and poultry diseases are becoming more and more complex, many of which are immunosuppressive. Immunosuppression refers to the impairment of the immune system of lives...

AI Technical Summary

Problems solved by technology

In this kind of diseases, some clinical symptoms are obvious, and its harmfulness is easy to be recognized and valued by people, while some diseases do not show obvious clinical symptoms, but the resulting immunosuppression reduces the body's immunity, which is easy to cause Poultry is infected with other secondary diseases, resulting in difficult treatment, high mortality, and huge economic losses to the breeding industry
