Traditional Chinese medicine residues prepared poultry feed additive and preparation method thereof

Abstract

The present invention discloses a traditional Chinese medicine residues prepared poultry feed additive and a preparation method thereof, which is characterized in that astragalus membranaceus residues are used as the main raw materials, brans of agricultural and sideline products are used as accessory materials, aspergillus niger and yeast two-step fermentation pattern, and aerobic and anaerobic two fermentation method are used, and the finished products are obtained by ultimately low-temperature drying, crushing, and screening. The beneficial results of the poultry feed additive are as follows: the aspergillus niger with a high activity is utilized to conduct physicochemical degradation of the astragalus membranaceus residues, the active ingredient dissolution rate is increased by 60%, and thus the product has medicinal functions and biological activity characteristics of plant polysaccharides; and the aerobic and anaerobic fermentations of the yeast are combined to enable the product to have medicinal functions and biological activity characteristics of biological polysaccharides. The product can effectively regulate poultry gastrointestinal microflora balance, reduce intestinal disease incidence, improve the survival rate, promote growth, lower feed conversion, enhance organism immunity and anti-stress ability, and improve economic efficiency of poultry farming.

Description

technical field [0001] The invention relates to the field of traditional Chinese medicine, the field of feed additives and the technical field of biopharmaceuticals, in particular to a feed additive produced by fermentation of complex microorganisms and a preparation method thereof. Background technique [0002] With the development of modern agriculture and the advancement of agricultural technology, people pay more attention to the health problems of farmed animals. At the same time, a large number of irrational use of antibiotics has led to the emergence of many problems such as drug-resistant bacteria and residues. The application of animal health care and disease prevention and control has attracted more and more attention, and many companies have begun to get involved in the field of traditional Chinese veterinary medicine. As a result, the consumption of traditional Chinese medicine resources has continued to increase, which has led to a resource crisis and seriously r...

Problems solved by technology

[0005] At present, new research content has appeared in the efficient utilization technology of traditional Chinese medicine residues. For example, the Chinese invention patent with the application number CN201310311826.5 discloses "a kind of fermented feed for traditional Chinese medicine residues and its preparation method", and the Chinese invention patent with the application number CN201210438591.1 The patent discloses "a method of using fungi to ferment traditional Chinese medicine dregs to produce feed". The Chinese invention patent application number CN201310145869.0 discloses "a preparation method for mixing traditional Chinese medicine dregs feed". The Chinese invention patent publication number CN101683124 The "method for producing feed additives for poultry and livestock by fermenting Astragalus dregs" was published, and the Chinese invention patent application number CN200910184046 disclosed "An Immunity Enhancer for Plant Source Animals Developed by Fermentation of Astragalus Dregs". In the patent, or the addition ratio of traditional Chinese medicine residues is low, less than 50% of the entire solid medium composition, or even less, neither can realize a large amount of consumption and utilization of traditional Chinese medicine residues, nor can it reflect the application value of traditional Chinese medicine residues; or The fermentation period of traditional Chinese medicine residue is long, the energy consumption is large, and it is easy to breed a large number of miscellaneous bacteria. The products provided by "Methods of Feed Additives for Poultry and Livestock" have ideal application effects on laying hens, but the use ratio of astragalus residues is not high, and the feeding dosage is too high, so that the effective value of astragalus residues cannot be fully utilized.

The patent "Plant-derived Animal Immunity Enhancer Developed by Fermentation of Astragalus Medicinal Dregs" uses the medicinal fungus Cicadae cicadae to carry out two-way fermentation of Astragalus residues, which greatly improves the medicinal value of the fermented product, but the fermentation time of this process is too long. Non-sterilization or incomplete sterilization can easily cause medium-term bacterial contamination, which seriously affects product quality. The growth conditions of cicadae are relatively harsh, and it is difficult to meet the requirements of large-scale production
