The invention provides a
traditional Chinese medicine compound type antibiotic-free
immunity-enhancing
feed additive and a preparation method thereof. The
traditional Chinese medicine compound type antibiotic-free
immunity-enhancing
feed additive is prepared from the following
raw material components: 10 to 20 parts of fructus
ligustri lucidi crude extract, 10 to 20 parts of folium artemisiae argyi crude extract, 5 to 10 parts of rhizoma belamcandae crude extract, 5 to 10 parts of algal
polysaccharide soluble
powder, 5 to 10 parts of
tourmaline powder and 50 to 80 parts of auxiliary materials; the preparation method comprises the following steps: weighing the raw materials and mixing to prepare
powder; preparing a granular preparation by adopting dry-process
granulation and arranging a dry-process granulator. The
traditional Chinese medicine compound type antibiotic-free
immunity-enhancing
feed additive provided by the invention has the beneficial effects that a plurality of components with an immunity-enhancing effect are compounded according to a certain ratio, wherein the fructus
ligustri lucidi crude extract, the folium artemisiae argyi crude extract, the rhizoma belamcandae crude extract and the algal
polysaccharide soluble powder are extracted and prepared according to a special technology; after the powder in the formula is uniformly mixed, the powder is prepared into granules by adopting a dry-process
granulation technology; an experiment result shows that various immunity indexes of pig bodies are improved through the compound formula and the pharmacological activity is obviously better than that of each single
raw material; the effect of the dry-process
granulation is stronger than that of a common granulation method.
