Fertilized eggs develop into the embryo egg in corresponding embryo age by different brooding time correspondences in hatching process, different
The embryo egg internal organizational structure in embryo age is different, just as human fetus' development, the division that different times embryonated egg is carried out point
Change process is different, and the natural brooding time of usual egg is 18 ~ 21 days, namely the hatching of 18 ~ 21 embryo ages is completed.For not homeomorphism age
Carry out handling the fertile chick into constitution difference, the present invention is exactly improved embryo egg hatching process according to this principle, to educate
Go out the Broiler chicks of initial growth excellent.
The present invention is when being fertilized hatching of breeding eggs the 5th ~ 6 day, the external source modifier A to its internal injection, wherein changing in external source
Choline Chloride and low-molecular weight chitoglycan are with the addition of in property agent A（Molecular weight is below 10000）Composition, during this period hatching egg embryo egg
There is the former base of epithelial cell group in bursa of Fabricius, and followed by former base develops mucomembranous cavity, and this stage is the first high of bursa of Fabricius development
Peak phase, the Choline Chloride now additionally added and low-molecular weight chitoglycan composition can stimulate the differentiation of epithelial cell, low molecule amount
The amino dissociated in chitosan can lift the activity of cell again, and epithelial cell can substantial amounts of differentiation generation lymphocyte, lymph
Cell can break up generation immunoglobulin again, be follow-up body constitution so as to provide premise for the synthesis of immunoglobulin
Good basis has been established in enhancing；When hatching the 11st ~ 12 day, there is the bud shape projection of epithelial sprout in the mucous epithelium of bursa of Fabricius, on
Skin bud constantly breaks up, grown up, and gradually gos deep into the tunica propria under mucous epithelium, meanwhile, lymphocyte is in sprout and sprout is all
Occur in the tissue enclosed, eventually form folliculus.While folliculus formation, mucous epithelium is also divided into follicle associated epithelium and filter therewith
Epithelium between bubble, this stage is the second peak of bursa of Fabricius development, has a large amount of lymphocytic epitheliums in bursa of Fabricius mucous layer tunica propria
Closely arranged in tunica propria towards mucomembranous cavity at the differentiation of folliculus and mucous epithelium related to this, the top of lympho epithelial follicle
Stratification；Folliculus is made up of cortex and medullary substance, and center is medullary substance, and cortex is enclosed on outside medullary substance.Medullary substance derives from mucous epithelium, more raised
Reticular epithelial cells constitute network, be flooded with lymphocyte, macrophage and a small amount of thick liquid cell, granulocyte in mesh,
The now external source modifying agent B to its internal injection, wherein the Choline Chloride added in external source modifying agent B, low molecule amount shell are poly-
Sugar and metallothionein composition can stimulate the propagation of mesh medium size lymphocyte and mononuclear macrophage, promote the differentiation of cell, carry
The content of immunoglobulin is risen, strengthens the constitution of chick, while the development of muscle, bone etc., wherein metallothionein can be strengthened again
White addition can be in scavenger-cell free radical, strengthen cytoactive, help to lift incubation rate, while reduce after chick again
The probability of angiocardiopathy occurs for phase growth；When hatching the 15th ~ 16 day, the later stage of hatching process is had been enter into, now into it
External source modifying agent C has been injected in portion, wherein thiazolidinedione, glutamine and wood frog oil component are with the addition of in external source modifying agent C,
Chick outer plumage, the formation of toe squama can be effectively promoted, and the development of embryo's chicken organ organ can be strengthened, the resistance of body is improved
Power；After each external source modifying agent injection treatment, a ultrasonication has been carried out, has now been conducive to allogenic material in embryo
The uniformity disperseed in main body, is conducive to it to utilize, while also reducing, moiety concentrations are too high to cause tissue damage even necrosis
Situation occur, and the activity of inside embryo point enzyme can be improved, be essential single stepping in the inventive method, in each step
Finally the growth characteristics of chick are effectively improved under rapid common cooperation.
The present invention has advantages below compared with prior art：
The present invention is for the purpose of improving chick body constitution, strengthen its growth characteristics, to the part rank for hatching of breeding eggs process of being fertilized
Improvement processing special Duan Jinhang, passes through the common point to the 5th ~ 6 embryo age of hatching, the 11st ~ 12 embryo age and the 15th ~ 16 embryo age
Reason, effectively improves the incubation rate of fertilization hatching egg, improves the body constitution of chick, enhances its resistance against diseases and growth is special
Property, the speed of weight increment and efficiency of feed utilization in broiler chicken later stage are improved, there is good economic benefit and promotional value.
