Abstract
The invention discloses a feed used in the later laying peak period of SPF (specific pathogen free) breeding hens and a preparation method thereof. The feed is characterized by comprising the following raw materials in parts by weight: 620-640 parts of corn meal, 200-220 parts of bean pulp, 25-35 parts of wheat bran, 15-25 parts of fish meal, 1-2 parts of 98% of methionine, 70-90 parts of limestone meal, 10-14 parts of calcium hydrophosphate, 2.5-3.5 parts of salt and 10 parts of premix. Compared with the traditional sterilization method, the preparation method is characterized by adopting a Co60 ray source for radiation sterilization and strictly limiting the radiation dose rate and radiation time. The feed subjected to radiation sterilization of the Co60 ray source has low nutrient losses, good sterilization effect and low cost and is suitable for industrial production.
Description
Technical field
The present invention relates to a kind of chicken feed and preparation method thereof, the particularly a kind of SPF of being used for kind chicken feed in peak later stage and preparation method thereof of laying eggs belongs to field of feed processing.
Background technology
The whole world has millions of agri-scientific researches and technology popularization personnel to be engaged in the research and the production of making the required SPF egg of animal vaccine source, can't find reasonable effective technology to stop the predicament that SPF chicken group support is grown the failure generation but face.
Produce SPF kind egg adopt conventional method for breeding cannot, we know that the breed of SPF chicken needs specific room, equipment and feed; SPF chicken feed is several special processed before feeding, and purpose is exactly the special pathogen of killing in the SPF chicken feed, and then are transported to SPF chicken breed house through specific channel; Not only the SPF chicken comprises all apparatus and poultry raiser etc., all can not bring any special pathogen into the SPF chicken and culture house; The purpose of all these loaded down with trivial details links has only a high-quality and safety of be exactly making international endorsement, does not carry the animal vaccine product of specific pathogen microorganism; Then, according to antibody test level and immunology principle in the animal body, and the vaccine characteristic is in rational time, carry out immunity to animal according to rational vaccine method for using, dosage targetedly; And the quality of vaccine is particularly important; Raw material-SPF egg quality of making the vaccine use is more crucial, and is domestic when paying close attention to the animal vaccine quality, more pays close attention to the nutrition and the processing technology of SPF chicken feed; Particularly determine SPF chicken group support to grow the process of killing and the technology of specific pathogen microorganism in the feed that success or failure play a crucial role; Our country puts into effect Policy Conditions separately for this reason, and the egg of making biovaccine must use international SPF egg, and this also is one of China's biovaccine goods key technology point in line with international standards at first; When the animal vaccine of only in this way producing can really reach the specific aim immunity; Be unlikely to take other specific pathogen microorganisms in the animal vaccine to,, spread the specific pathogen microorganism of carrying because of vaccine to such an extent as to cause in this zoonotic while of immunity; Cause the propagation and the diffusion of other infectious diseases, with the happy life of protection human health and happiness.
At present both at home and abroad the trend of research is to kill the specific pathogen microorganism in the SPF chicken feed with processing technology efficiently; In this processing procedure, avoid destroying the nutritive index in the feed as much as possible; Particularly do not destroy the protein in the feed, the composition of vitamin as far as possible; But this is a vision, and the way in the actual production is when the design feed formula; Add excessive nutriment; The nutriment that particularly in the processed process, is easy to processed operation destruction wants excess to add, and to ensure that feed is easy to the nutritional need that ruined nutriment can satisfy SPF chicken crowd in the pathogenic microbe killing process, brings into play SPF chicken crowd's production performance as far as possible;
Adopting at present the more method of killing special pathogen employing in the SPF kind chicken feed in the world is greatly the high-pressure water vapor sterilization; Pack handy specific Polypropylence Sheet to the good finished feed of production exactly and pack, in the high-pressure chamber of packing into, the feeding water vapour makes it pressure and reaches 4.5 standard atmospheric pressures; Temperature reaches more than 120 degrees centigrade; And keep water vapour to flow, and sterilization time reached more than 45 minutes, and sampling detects under special circumstances then; Can use after guaranteeing not contain special pathogen in the feed; The method is time-consuming, effort, waste resource, but also will need the steam boiler fire coal a large amount of with waste, and coal also will produce pollutant such as waste gas such as a large amount of carbon dioxide and dust and environment is caused very big pressure and pollution in combustion process; Simultaneously; Also cause a large amount of losses of nutriment when in utilizing the autoclaved process of water vapour, killing special pathogen, more trouble be and be cause feed humidity and moisture increase and cause the shortening of feed storage time, even cause the growth of mould in the feed and the generation of mycotoxin at high temperature season.
The method that the present invention adopts is the Co that uses atomic energy
60Carry out irradiation; Take certain irradiation dose and exposure time to kill the method for the special pathogen in the feed; The nutritive index of the feed that needs because of SPF kind chicken different life has a long way to go; Feed formula has a long way to go with the feed raw material that need, so kill the needed atomic energy Co of special pathogen in the feed
60Irradiation dose and exposure time gap also very big, so concentrations of nutrient such as multivitamin that in the irradiation process, is easy to lose in the feed and mineral trace element, protein, amino acid, energy and the conventional chicken feed of planting have very big difference.
For this reason, the present invention designs the feed formula that following suitable SPF kind chicken was used in the peak later stage of laying eggs, according to the atomic energy Co that the present invention adopted
60Irradiation dose and exposure time kill the SPF kind chicken of feeding behind the special pathogen in the feed and obtained better effects.
Summary of the invention
The present invention is through lay eggs the peak later stage nutritional need of SPF kind chicken of (421 ages in days-500 eliminate) of analysis-by-synthesis, scientific and reasonable the lay eggs feed in peak later stage of a kind of SPF of being used for kind chicken that made.
The lay eggs feed in peak later stage of a kind of SPF of being used for kind chicken of the present invention; It is characterized in that being made up of each raw material of following weight portion: 620-640 part corn flour, 200-220 part dregs of beans, 25-35 part wheat bran, 15-25 part fish meal, 1-2 part content are methionine, 70-90 part stone flour, 10-14 part calcium monohydrogen phosphate, 2.5-3.5 part salt and 10 parts of premixes of 98%; Contain compound vitamin 20kg, grandidierite dimension 200kg, Choline Chloride 200kg, imported fish meal 400kg and 200 order zeolite powder 180kg in the described premix wherein per ton, said each raw material mixes the back sterilization and promptly gets.
In a preferred embodiment of the invention; The lay eggs feed in peak later stage of the described SPF of being used for kind chicken is made up of each raw material of following weight portion: 634 portions of corn flour, 210 parts of dregs of beans, 30 parts of wheat brans, 20 parts of fish meal, 1.6 parts of content are 98% methionine, 80 parts of stone flours, 12 parts of calcium monohydrogen phosphates, 3 portions of salt and 10 parts of premixes; Contain compound vitamin 20kg, grandidierite dimension 200kg, Choline Chloride 200kg, imported fish meal 400kg and 200 order zeolite powder 180kg in the described premix wherein per ton, said each raw material mixes the back sterilization and promptly gets.
