Abstract
The invention relates to a preserving and processing method for hatching eggs before batch. The method comprises the steps that eggs are selected and stored, namely, qualified hatching eggs are placed into egg trays, the egg trays are horizontally placed on an egg tray frame of an egg trolley; warehousing is conducted on the eggs, wherein the warehousing temperature is 18-20 DEG C, the relative humidity is 70-75%, storage time is 24-72 hours, specifically, the storage time is 24-48 hours in summer and is no more than 72 hours in other seasons; eggs are turned, wherein the hatching eggs are overturned once every 2-3 hours within the storage time, and the egg turning angle is 45 degrees; the eggs are sent to an automatic hatcher to be hatched. The preserving and processing method for the hatching eggs before batch has the advantages that the setting of the storage time, the setting of the warehousing temperature ranging from 18 DEG C to 20 DEG C, and the setting of the relative humidity ranging from 70% to 75% maintain fresh quality of the hatching eggs, and improve chick hatching rate. The hatching eggs are turned when stored, embryos are prevented from adhering shell membranes, the hatching egg fertilization rate is improved, and the chick hatching rate is 10% higher than that before egg turning.
Description
Technical field
The present invention relates to the preservation treatment method before a kind of hatching of breeding eggs.
Background technology
Before hatching of breeding eggs, in order to keep the fresh quality of kind of egg, hatching factory and kind chicken house have special-purpose kind egg storehouse, specialize in storage kind of egg and use.After ovum fertilization, germinate soon, through the continuous division of 24 hours, formed a cellulous blastodisc.After chicken embryo forms two germinal layers in vivo, egg is output, meets cold rear temporary transient stasi.The critical temperature of embryonic development is 20.9 ℃, and the critical temperature meeting that storage temperature surpasses embryonic development causes emerging the date in advance, and embryonic death increases, and affects incubation rate.Contrary storage temperature is too low, as lower than 0 ℃, plants egg and can lose because enduring cold hatchability.Humidity environment is also very important condition, too high kind of egg meeting moldy metamorphism of humidity, and too low kind of egg of humidity can affect incubation rate because of moisture evaporation.How to confirm kind egg storing temperature and humidity ，Ge producer are according to the different practical data that have oneself of area, season.Planting the egg-turning program of egg in hatching process is apparent to the effect of embryonic development, always be subject to people's attention, and often pay attention to not in egg-turning program, the egg-turning frequency of kind of egg storage life, in fact the egg-turning process of storage life and egg-turning frequency have considerable influence to the chicken rate that goes out of chick hatching process.
Summary of the invention
In view of above-mentioned prior art present situation, the invention provides a kind of fertilization rate that improves kind of egg, go out the preservation treatment method before the hatching of breeding eggs of chicken rate.
For achieving the above object, the technical scheme adopting is in the present invention: the preservation treatment method before a kind of hatching of breeding eggs, is characterized in that: step is as follows,
The first step: select egg, dress egg, the kind egg that transportation is come is selected again, underproof kind of egg is picked out qualified kind egg is put into incubator tray, then incubator tray is kept flat on egg car with horizontal level;
Second step: warehouse-in stores, and the egg car that kind of egg is housed is pushed to special-purpose egg stock and put, and stock's temperature is 18～20 ℃, relative moisture is 70 ﹪～75 ﹪, and the storage time is 24～72 hours, is specially, storage time in summer is 24-48 hour, and other times are for being no more than 72 hours;
The 3rd step: egg-turning, planting egg every 2～3 hours within the storage time will be to kind of egg egg-turning once, egg-turning angle is 45 ℃, egg-turning turns on one's side the incubator tray framework that is horizontal level to the left or to the right to 45 ℃ (being 45 ℃ of angles with horizontal line) for the first time, egg-turning turns on one's side the incubator tray framework that is 45 ℃ to 45 ℃ to the right or left for the second time, (being 45 ℃ of angles with horizontal line), for the third time to the moved in circles for N time to the storage time, and every egg-turning once all will make a record;
The 4th step: deliver to automatic incubator and enter hatching program.
The invention has the beneficial effects as follows: the storage time is made as 24～72 hours, storage time in summer is 24-48 hour, other times are that the setting that is no more than 72 hours and stock's temperature are that 18～20 ℃, relative moisture are the setting of 70 ﹪～75 ﹪, kept planting the fresh quality of egg, for improving the incubation rate of chick, laid the foundation.Kind of egg carries out egg-turning program in egg stock is put, and can prevent embryo and shell membrane adhesion, has improved the fertilization rate of planting egg, and it goes out chicken rate and compares not egg-turning and improved 10 ﹪.
Embodiment
Before hatching of breeding eggs, plant a preservation treatment method for egg, step is as follows:
The first step: select egg, dress egg, the kind egg that transportation is come is selected again, and underproof kind of egg selected away, and qualified kind egg is put into incubator tray, greatly head-up, then incubator tray is kept flat on the incubator tray framework of egg car with horizontal level;
Second step: warehouse-in stores, it is to keep kind of a key for egg fresh quality that warehouse-in stores, because being put on egg car, kind egg can not directly enter hatching program, need a warm, with avoid kind of egg enter after hatch machine due to the unexpected rising of incubation temperature to embryo cause stress, can cause reduction incubation rate.The egg car that kind of egg is housed is pushed to special-purpose pre-Wen Ku.Stock's temperature and humidity are to keep kind of a most important condition for egg fresh quality, and in order to keep the fresh quality of kind of egg, stock's Temperature Setting is 18～20 ℃, and relative moisture is set as 70 ﹪～75 ﹪.The setting in storage time is also very important factor, and the incubation rate of chick is had to direct impact, so the storage time is made as 24～72 hours, the steady egg time in summer is 24-48 hour, and other times are for being no more than 72 hours; More than set the fresh quality that can keep kind of egg, for improving the incubation rate of chick, lay the foundation.
The 3rd step: egg-turning, plant egg and in egg stock is put, carry out egg-turning program, can improve fertilization rate, be the key condition of high hatchability, egg-turning can make kind of egg thermally equivalent within the storage life, prevents content and eggshell adhesion, can promote chick embryo development.Planting egg every 2～3 hours within the storage time will be to kind of egg egg-turning once, egg-turning angle is 45 ℃, egg-turning turns on one's side the tray frame that is horizontal level to the left or to the right to 45 ℃ (being 45 ℃ of angles with horizontal line) for the first time, egg-turning turns on one's side the tray frame that is 45 ℃ to 45 ℃ to the right or left for the second time, (being 45 ℃ of angles with horizontal line), for the third time to the moved in circles for N time to the storage time, and every egg-turning once all will make a record.
