Preparation method for traditional Chinese medicine feed additive for reducing content of cholesterol in eggs

Abstract

The invention discloses a preparation method for a traditional Chinese medicine feed additive for reducing content of cholesterol in eggs. The preparation method comprises the following steps: getting traditional Chinese medicines including hyodeoxycholic acid, grape seeds, Chinese chive seeds, smoked plums, cinnamon, mulberries, wild jujube seeds, garlic, clove and radix glycyrrhizae; performing superfine grinding on the traditional Chinese medicines, adding an alcohol solution and boiling with strong fire, preserving the heat with slow fire, cooling and filtering, concentrating the filtrate, adding white sugar and boiling, inoculating lactobacillus, zygosaccharomyces bailii and acetobacter xylinum after cooling to the room temperature, and fermenting for 168 hours to grow out white fungus blocks; performing vacuum-drying on the white fungus blocks at a low temperature and embedding the white fungus blocks, adding the white fungus blocks into feed in proportion, and pelletizing and cooling at a high temperature to prepare the granular feed. The traditional Chinese medicine feed additive has the effects of increasing quantity of effective microbial communities in the intestinal tract, improving the immune function and increasing the disease resistance of chicken bodies, and has the benefits of reducing the content of cholesterol in eggs. The preparation method is simple, content of live bacteria is high, use is convenient, no toxicity is realized and the cost is low.

Description

technical field [0001] The invention belongs to the technical field of feed additives, and in particular relates to a preparation method of a natural green traditional Chinese medicine feed additive for preventing and lowering the cholesterol content in eggs. Background technique [0002] Cholesterol, also known as cholesterol, isooctenol, cholest-5-en-3β-ol, is a steroidal compound with the chemical formula C 27 h 46 O. Under the solid state is a white or off-white flaky crystal. Cholesterol is widely present in animals, especially in brain and nerve tissue, and is also high in kidney, spleen, skin, liver and bile. Its solubility is similar to that of fat, insoluble in water, slightly soluble in ethanol, methanol, etc., easily soluble in acetone, petroleum ether, ether, chloroform and other solvents. Cholesterol is an indispensable and important substance in animal tissue cells. It not only participates in the formation of cell membranes, but also is an important raw ma...

Problems solved by technology

[0006] At present, there are many ways to reduce the cholesterol content in eggs. Some trace ingredients can be added to the diet of laying hens, such as: copper, fish oil, allicin, Chromium, drugs, etc., these additives can reduce the cholesterol content in eggs to a certain extent, but there are still some problems: such as copper, fish oil, etc., the general reduction rate is about 15%. Although it is very obvious from statistical considerations, the cholesterol content in eggs It is still a very high value; some additives have a good effect on lowering cholesterol, but they are expensive, such as HMGR inhibitors, which can generally reduce the cholesterol content in egg yolk by 40% to 50%, and are mostly used for human medicine, thus increasing the cost of feed; Some additives can greatly reduce the cholesterol content, but also reduce the egg production at the same time, such as high-dose copper (250mg / kg)

Su Zhenfang and others disclosed a feed additive for reducing cholesterol content in eggs [Application No.: 200710115302.3], adding Alisma, seaweed, cassia seed, perilla seed, hawthorn, and montmorillonite to the feed. Most of these added ingredients belong to Chinese herbal medicines , without any treatment, just crushed through a 60-80 mesh sieve, added to the feed at 2% to 6%, and let the chicken eat freely. According to the feeding habits of the chicken, it may affect the decrease of the cholesterol content in the egg Effect; Zhang Rude etc. disclose a kind of feed additive [application number 200710009910.6] that reduces the content of cholesterol in eggs. Cholesterol content, because this feed contains fish oil and other substances, it may make eggs contain a certain fishy smell, and it increases the cost, so it is not easy to realize industrialization; No. 201410373903.4], the invention is to feed chickens with 7% to 8% of green tea powder, 2.5 to 5wt% of fish meal, and various trace elements in the full-price basal ration, wherein Cu: 0.18 to 0.22g , may reduce the cholesterol content in eggs by about 15%, but the cholesterol content in eggs is still a very high value

[0007] and traditional Chinese medicine and microorganisms are fermented together to prepare traditional Chinese medicine feed additives, the microecological preparations are vacuum-dried, and then embedded in double-layer microcapsules to make a feed additive that can A feed additive for reducing cholesterol content in eggs, which has not been reported in the prior art
