Description

A kind of feed formula and its application for layer breeding

Technical field

The invention belongs to feed formula technology field, it is related to a kind of feed formula for layer breeding and its application.

Background technique

Egg amino acid rich in, minerals and vitamins, and the composition of its amino acid and needed by human body amino Acid proportion is close, and is ideal food.At present although the livestock on hand of China laying hen and egg product amount occupy first place in the world, but egg The production level of chicken is low, there are no the extensive operation mode for completely disengaging consumption resource, many advanced technologies and management method Without promoting and applying well in production, the production performance of laying hen, the production performance of China laying hen and developed country are influenced Compared to there are also biggish gap, about 15-16 kilograms of average egg yield of 72 week old chicken chicken of China at present, laying period death mortality For 20-25%, and in about 19.5-20.5 kilograms of average egg yield of 72 week old chicken chicken of the developed countries such as the U.S., Holland, laying period Dead mortality is 6-7%.The increase of feeding quantity is too fast, and chicken single rate is low, causes breeding layer chicken at high cost, and environment is disliked Change；In feed and excessive addition antibiotic in drinking-water when disease generation or chicken mass-send sick in order to prevent, not by regulation or animal doctor Prescriptions, such as it is serious using illegal drug, overdose medication phenomenon lack of standardization, keep drug residual in egg, environment It stays serious；In addition practitioner's idea is outmoded, diseases control measures are ineffective etc. causes man, China poultry diease multiple, harm is serious, As the principal element for restricting the sustainable development of China poultry and benefit raising.Conventional feed raw material is fed in laying hen production process Immunity of layer chicken, resistance, anti-stress ability are low, need to add in conventional feed a large amount of antibiotic could maintain it is intensive feed The existence of raising layer, but also there are the bad Egg Quality produced of the health status of laying hen is low, albumen yolk is thin, egg Shallow, foreign matter egg (blood cake, meat spot) ratio height of yellow color etc. is also generally existing, and this low-quality egg is not able to satisfy the people increasingly to height The needs of quality egg demand.

Summary of the invention

In order to overcome the disadvantages mentioned above of the prior art, the present invention provides a kind of feed formula for layer breeding and its answers With it can significantly improve the immunity of laying hen, resist added with natural bioactivity substances such as Chinese medicinal herbs, nutrient for plants Power, anti-stress ability, keep laying hen to be in good health state in entire production process, and the egg quality produced is excellent Good, egg contains high docosapentaenoic acid, low cholesterol, selenium-rich.

The technical solution adopted by the present invention to solve the technical problems is: a kind of feed formula for layer breeding, The mixture that group is divided into base grain, improves Egg Quality functional component mixture and disease-prevention health ingredient, the addition weight ratio of three are 9 3.8:6:0.2；Wherein improving Egg Quality functional component component of mixture includes pine needle meal and extract, Paprika and extraction Object, garlic slice and allicin mixture, marigold, seawood meal, Se-enriched yeast, glutamic acid, methionine and arginine；Disease-prevention health The component of the mixture of ingredient includes Radix Glycyrrhizae, illiciumverum, fennel, folium artemisiae argyi, Chinese ephedra, radix scutellariae, cordate houttuynia, Herba Andrographitis and Radix Isatidis.

The component and its weight percent of the base grain are as follows: dregs of beans 25-35%, corn 55-65%, rice bran 5-10%, shellfish The shell powder 3-7% laying hen minerals 1-2% and dedicated multidimensional multi-vitamins 0.5-1% of egg；By said components according to weight Percentage co-grinding is crossed to 10-20 mesh.

Each component and its weight percent in the raising Egg Quality functional component mixture are as follows: 20-40 mesh pine needle meal And extract mixtures 25-35%, 20-40 mesh Paprika and extract 10-25%, 20-40 mesh garlic slice and allicin Mixture 10-25%, 20-40 mesh marigold 6-15%, seawood meal 6-15%, 40-60 mesh Se-enriched yeast 5-8%, 40-60 Mesh illiciumverum 3-6%, 40-60 mesh fennel 3-6%, 40-60 mesh glutamic acid 1-3%, 40-60 mesh methionine 1-3%, 40-60 Mesh arginine 1-3%；It is stirred in proportion.

The component and its weight percent of the mixture of the disease-prevention health ingredient are as follows: 80-100 mesh Radix Glycyrrhizae 20-30%, 80-100 mesh folium artemisiae argyi 20-30%, 80-100 mesh cordate houttuynia 20-30%, 80-120 mesh Chinese ephedra 10-20%, 80-120 mesh radix scutellariae 10-20%, 8-120 mesh Herba Andrographitis 10-20% and 80-120 mesh Radix Isatidis 10-20%；It is stirred.

The pine needle meal and extract include pine needle powder extracts, wherein pine needle powder extracts by with petroleum ether to pine needle 2 hours of powder refluxing extraction are made, and wherein the mass ratio of pine needle meal and petroleum ether is 1:10, collect extracting solution, to extracting solution into Row vacuum concentration recycling petroleum ether solvent obtains pine needle powder extracts, and pine needle powder extracts are made with pine needle original powder by 30:70 mixed pressure Pine needle meal and extract.

The garlic slice and allicin mixture powder are made with commercially available allicin element by 80:20 mixed pressure to 40 mesh garlic slice powder Garlic slice and extract.

The Se-enriched yeast adds appropriate selenium compound as culture medium using molasses, and saccharomyces cerevisiae kind, addition are accessed after sterilization The nutritive salt such as nitrogen, phosphorus carry out fermented and cultured, at 30 ± 1 DEG C of temperature, aerlbic culture 24-48 hours under conditions of pH4.5-5.0, So that inorganic selenium is combined into the selenium of organic, yeast is isolated by centrifugal process, is obtained with after water repeated flushing through vacuum drying The Se-enriched yeast of pale yellow powder shape.

The dedicated multidimensional multi-vitamins of egg are Shangqiu You Mu animal health-care product Co., Ltd product, and main component refers to It marks and contains in every 1000g: ten thousand IU of retinyl acetate 260-650；Tie up raw ten thousand IU of D50-200；Folic acid is greater than 600mg.

The selenium compound is sodium selenite, wherein molasses: the mass ratio of selenium compound is=1-2:100.

A kind of application of the feed formula for layer breeding, application process is: by base grain, improve Egg Quality function at The mixture of mixture and disease-prevention health ingredient is divided to mix complete uniformly rear nursing in proportion, by every one gram of laying hen drinking of feeding Material, by feed addition into drinking water, drinks 2-4 times for one week to enhance laying hen disease resistance ability.

The positive effect of the present invention is: raw material, which are all selected, easily decomposes degradable natural material, do not add antibiotic, Hormone, illicit drug do not have the residual phenomena in egg, in environment such as antibiotic；Improve the immunity of laying hen, resistance, Anti-stress ability guarantees that laying hen is in good condition of health, 72 week old average egg yield 18.5-2 in entire production process 0 kilogram, beyond domestic 3-4 kilograms of average egg yield, laying period death mortality 5.5-6.5% is washed in a pan than domestic laying period death The low 14-19% point of rate or even slightly lower developed country's mortality are eliminated, laying hen integrated culture cost is reduced；It solves very well because of egg The egg qualities differences such as the egg albumen yolk that chicken health status is poor and produces is thin, yolk color is shallow are not acceptable to the market approval The problem of.Guarantee that the egg quality produced is excellent, egg is containing high docosapentaenoic acid, low cholesterol, the fortification egg of selenium-rich, guarantor Strong egg and green egg are received by the market.
