preparation example 1

[0080] Extract the effective components of medicinal materials

[0081] (1) Prepare 685g of medicinal raw materials in the following parts by weight: 50 parts of dandelion, 20 parts of oregano, 10 parts of astragalus, 10 parts of Codonopsis pilosula, 20 parts of forsythia, 15 parts of ginkgo biloba, and 50 parts of wolfberry. After mixing the above medicinal materials for dust removal and impurity removal, crush them to 50 mesh with a pulverizer, put them in an extraction container, add 7L of distilled water, heat to 80°C, soak for 4 hours, and use ultrasonic extraction for 2 times, each time for 30 minutes. The ultrasonic power is 200W; the extracted solutions are filtered and combined to obtain the filtrate I, which is concentrated under reduced pressure at 30°C to about 600ml, and the filter residue is placed in the extraction container again.

[0082] (2) Add 6L of ethanol solution with a volume fraction of 60% to the container, extract at 60°C for 3 hours, collect the fil...

[0085] Extraction treatment and formulation preparation

[0086] (1) Preparation of extract-soybean lecithin complex

[0087] Mix the extract concentrate prepared above with 3.8kg soybean lecithin, add 15kg of 95% ethanol, slowly stir and compound at 50°C for 1 hour, evaporate and recover the solvent, and control the water content within 8% by vacuum drying at 20°C. The medicinal material extract-lipid complex solid was obtained and pulverized.

[0088] (2) Dissolve chitosan with a viscosity of about 300cP in an acetic acid solution with a mass fraction of 1.5% to prepare a 3wt% chitosan solution, then add Tween 80 to the solution to a concentration of 2wt%, and add ethyl cellulose to 3wt%, mixed evenly to obtain a chitosan mixed solution; under stirring conditions, the obtained medicinal material extract-lipid complex powder was mixed with the chitosan solution, and the gelatin solution was used as a binder to prepare a soft material, and prepared in a granulation equipment ...

[0090] Extraction and coating of immune enhancement components

[0091] (1) Dry the medicinal material residue after extracting the effective components, wash it twice with water to remove residual ethanol, mix it with the proportional amount of compound enzyme powder preparation, and then add 5 times the mass of distilled water for enzymolysis; the compound enzyme powder preparation and medicinal material The content of cellulase in the residue mixture is 80U / g (based on the dry weight of medicinal material residue), the content of amylase is 20U / g, and the content of compound protease is 30U / g.

[0092] (2) First, the first enzymatic hydrolysis was performed at a temperature of 50°C and a pH of 5 for 3 hours, and then continued at 65°C and a pH of 7.0 for 2 hours; after the two enzymatic hydrolysis, heat in a boiling water bath for 15 minutes Inactivate the enzyme, filter the enzymatic hydrolysis solution, collect and concentrate the filtrate, and freeze-dry to obtain a comp...

Abstract

The invention relates to an antibiotic-free fattening sheep feed containing natural extract components without irritating smell and its preparation. The compound is extracted from the antibacterial and immune-enhancing effective components treated by compound treatment, the fermented product of medicinal material residue after enzymolysis, and the fermented product processed by aging. A mixed feed composed of feed and raw meal; the preparation method includes the steps of antibacterial and immune enhancing component extraction, compounding, feed fermentation and mixing, and granulation; the antibiotic-free feed component of the present invention is aimed at the digestion characteristics of fattening sheep The preparation can significantly improve the disease resistance and feed conversion efficiency of fattening sheep, and significantly improve the fattening effect and comprehensive economic benefits.

Description

technical field [0001] The invention relates to the field of sheep feed during the fattening period and its preparation, in particular to a fattening feed without adding antibiotics which comprehensively processes and utilizes natural Chinese herbal medicines and a preparation method thereof. Background technique [0002] At present, in order to overcome the abuse of antibiotics in modern animal husbandry, more and more Chinese herbal medicines are used as feed additives in feed. Although a large number of studies have shown that some Chinese herbal medicines have the functions of antibacterial and enhancing animal immune function, however, whether they are used directly as feed additives or as additives after extracting active components, the compounded Chinese herbal medicines have complex components, low content of active components, and There are problems such as poor palatability, toxic and side effects caused by large dosage, and high cost, which makes it difficult for...
