Abstract

The invention relates to the technical field of agricultural waste recycling and feed industry, in particular to a traditional Chinese medicine residue feed additive as well as a preparation method and application thereof. The preparation method comprises the following steps: drying traditional Chinese medicine residues, crushing to obtain a crushed material, mixing the crushed material with a compound enzyme, carrying out enzymolysis to obtain an enzymolysis material, mixing the enzymolysis material with lactobacillus plantarum LP-01, carrying out anaerobic fermentation to obtain a fermented material, mixing the fermented material with a yeast extract and manganese sulfate to obtain a mixture, mixing the mixture with water, extracting, filtering to obtain a filtrate, concentrating, and carrying out freeze drying to obtain a finished product. The traditional Chinese medicine residue feed additive is obtained. By adopting the traditional Chinese medicine residue feed additive provided by the invention, the diarrhea rate of weaned piglets can be reduced, the stress resistance of aquatic animals is improved, and the growth performance of poultry is improved.
