Description
Technical field
The invention belongs to feed additive field, be specifically related to a kind of pig's feed additive product and preparation method thereof.
Background technology
In modern livestock and poultry cultivation process, in order to prevention and therapy Animal diseases, the excessive antibiotic product of normal use guarantees animal health, but excessive antibiotic use often causes the quality of animal meat product and product thereof to decline and antibiotic resistance strengthens, and causes human health to be also subject to having a strong impact on of antibiotic problem by the transmission of food chain.Be derived from more natural natural materials and not only there is good nutritive peculiarity, also there is the effects such as antiviral, anti-inflammatory, anti-oxidant, conditioner body immunity function simultaneously, have broad application prospects.
Glossy ganoderma [GanodermaLucidum (Leyss.exFr.) Karst.], also known as polyporus lucidus, belongs to Basidiomycotina, Aphyllophorales, Ganodermataceae, Ganoderma.Doctor's allusion quotation in successive dynasties playbacks glossy ganoderma in " medicine-feeding ", and its ranking is before ginseng.Shennong's Herbal, Compendium of Material Medica are recorded, glossy ganoderma materials for improving vision, tonifying liver gas, calm the nerves, beneficial essence, the beneficial motive, beneficial temper, beneficial lung qi, kidney-nourishing gas, logical nine orifices, ear acute hearing, bright, the sharp joint of order, diuresis, skin maintenance, be first-class excellent tonic product.GL-B can promote the synthesis of protein, nucleic acid, has facilitation to the renewal of serum, liver and bone marrow cell protein or nucleic acid, synthesis, and it is one of glossy ganoderma principle active component of strengthening the body resistance to consolidate the constitution.GL-B is mainly present in lucid ganoderma fungus fructification, sclerotium, mycelium or zymotic fluid; The ganoderic acid be present in glossy ganoderma has pain relieving, calmness, suppression histamine releasing, detoxifies, protects the liver, malicious tumoricidal function, is one of principle active component of glossy ganoderma.
Medicinal plant purple perilla is the band leaf spray of labiate purple perilla [Perillafrutescens (L.) Britt.], is used as medicine so that stem, leaf and son are real.Purple perilla belongs to comprehensive crossover commodity, both pharmaceutically acceptable, is clinical common medicine, can eats again.Form of being used as medicine claims lac encrusted twig with stem, and leaf, also known as Su Ye, induces sweat, and son, also known as perillaseed, FRUCTUS PERILLAE, red perillaseed, is the important component of Suzi Jiangqi Tang.Expelling cold and relieving exterior syndrome, regulating the flow of QI to ease the stomach.Cure mainly cold, fever, be afraid of cold, lossless, uncomfortable in chest, cough, separates the poisoning stomachache caused of crab, diarrhoea, the diseases such as vomiting.
The bark of eucommia is China's traditional Chinese medicine material, aboundresources.Chinese veterinarian's medicine circle traditionally using Bark of Eucommia Ulmoides, leaf as livestock and poultry growth accelerator, growth promotion, increase egg, lactagogue and animal immunity potentiator application.The benefit of peasant to the bark of eucommia hello animal is existing to be familiar with, and emotion more easily accepts.The tentative confirmation of test in recent years, Bark of Eucommia Ulmoides, leaf extract, Eucommia Leaf Powder are improved the effect of poultry, fowl, the fish general level of the health and production performance; Healthy to the high age in days chicken of improvement, delay power of laying eggs and decline and have certain effect, and there is the possibility improving animal flesh, Egg Quality.Existing Preliminary Experiment confirms, eucommia leaf extract has the effect identical with chemical anti mildew agent as Midew preventive for feed, and has the potentiality of exploitation feed novel antioxidant.From feedstuff industry development and the requirement of green cultivation, its superior antibacterial growth promotion performance of folium cortex eucommiae has obtained everybody extensive accreditation.Test proves, eucommia leaf extract has the effects such as broad-spectrum antibacterial, anti-oxidant, scavenging free radicals and raising immunity, has and promotes that livestock and poultry grow fast; Prevent and cure diseases; The effectiveness such as substitute antibiotics.
Carotenoid is a class in Polyenes that is yellow, orange or red, and it is the most ubiquity of occurring in nature is also the most stable natural colouring matter, is extensively present in many animals and plants.Carotenoid as a kind of excellent food additives and the nutritional supplement improving human nutrition, its fine quality and effect, for a long time just generally acknowledge by countries in the world, be described as most promising antioxidant.At present, carotenoid is widely used in the industries such as food, medicine, cosmetics and feed addictive, the application prospect good due to it and the function of brilliance, for a long time extremely people's favor.
Extract carotenoid complex process from natural food, cost is high and wastes abundance of food, therefore become study hotspot by Production by Microorganism Fermentation carotenoid, be particularly widely studied as bacterial classification with not toxigenic rhodotorula.Rhodotorula is the one in saccharomycete, belongs to stealthy ball Saccharomycetaceae, is unicellular fungi.Rhodotorula body is oval or ellipse, and mode of reproduction is polygon gemmation, can produce significantly red or xanthein.Rhodotorula can produce the multiple pigments such as beta carotene, torulin and torularhodin.
Copper is the required trace element of animal, all plays a very important role for the health of animal and growth.At present, existing many tests confirm, the copper adding (250mg/kg) in Weaned Growing Pig Diets using copper sulphate as copper source can improve the same feed intake of piglet, daily gain and meat feed ratio.But the copper sulphate adding this inorganic states in feed also exists a lot of problem, as low in pig absorptivity, with other component compatibility in diet is poor, excretion rate is high, contaminated environment etc.But saccharomycete has huge legendary turtle and closes the ability of copper particle, and it is except the copper containing high-load and high-absorbility, also have good stability, and diet in good, the advantage such as absorptivity is high, excretion rate is low, environmental pollution is little of other component compatibility.
It is significant to feed additive industry development how effective exploitation obtains green feed additive product with natural plants or fungi.

(5) extraction of carotenoid:
1g dry mycelium is put into 100mL triangular flask, and add the hydrochloric acid soaking at room temperature 1h of 5mL3mol/L, boiling water bath 4min, cools rapidly, and 3000r/min is centrifugal, and 15min is precipitated as cell residue, is settled to 20mL extraction, obtains carotenoid leaching liquor with acetone.
(6) mensuration of carotenoid
After suitably being diluted by extract, under 475nm condition, measure absorbance value with 722 type spectrophotometers.Be calculated as follows carotenoid content:
In formula: A λ
maxfor the absorbance at 475nm wavelength place; D is extension rate when measuring sample; V is acetone consumption (mL); 0.16 is the molar extinction coefficient of carotenoid; W is rhodotorula dry cell weight (g).
(7) yeast copper content measures
Use aas determination.
(8) culture presevation
The above-mentioned rich copper ocean rhodotorula WYN1 through domestication is preserved in China typical culture collection center, and deposit number is: CCTCCNo:M2014592.
