One, soft carapace egg
Soft carapace egg calls frivolous case the egg again, the ply of this kind of egg is normaller thin, light jog is touched or egg pressing egg is met instantly broken. Its cause of formation is like below a few respects:
1, what production chorion lacks in feed is mineral, basically be devoid calcium or vitamin D, or long-term and ceaseless high yield, the calcium in feed already cannot satisfy gallinaceous body to synthesize the need of chorion character.
2, feed mix not divide evenly, collocation is unture, or calcic phosphor does not press 2:1scale matchs. Manganese is lacked in feed, affected the metabolization of calcic phosphor.
3, environmental temperature is exorbitant, chicken feed is about to drop, collect appetite to reduce the need that absorbs the calcic simple measure inside gallinaceous body to cannot satisfy gallinaceous bodily form to become chorion.
4, henhouse narrow, foul, damp, chicken group density is too big, the hen lacks motion, make calcic phosphor cannot be carried normally supply chorion to form a department.
5, the function of egg carapace gland is abnormal, cannot secrete enough chitinous.
6, the hen is scared before producing an egg, function of reproductive system nerve is disturbed and happen disorder, affect chitinous cent ooze.
7, because mould toxin is toxic, cause reproduction line function is unbalanced, ovarian function is lost or degrade, make chicken produces soft carapace egg thereby, or quantity yield an egg is reduced or lose the ability that continues to produce an egg.
In addition, produce a disease, after using dosage, vaccination short-term inside also can produce soft carapace egg.
2, the egg that do not have housing
Yielding egg does not have housing, only soft egg film is lapping, much discovery at producing the high yield hen with much egg, because the lack in feed makes the vitamin D of chorion and calcium pledge,basically be.
3, double carapace egg
Because the egg already formed incrustation hind inside the uterus,this is, ignore sweat from every pore sweat from every pore, or physiology is abnormal, oviduct of as a result happens go against peristalsis, make the tube wall before the egg, recede suddenly, the egg arrives from uterine go back again tubal upside.
After return to normal, egg along tubal be issued to lower levels, exciting tubal mucous membrane secretes albumen again, the egg the bag is inside.
The 2nd times when the egg be issued to lower levels comes when the uterus, prick exciton tube wall to secrete calcic qualitative fluid again, formed the 2nd chorion, heavy bag go up and make double carapace egg.
4, the egg that knit housing
Namely the egg that chorion contains Chu Wen, the expressional shrinkage of housing, coarse, because there is calcic qualitative precipitation on chorion,this is, it is the sequela of contagious bronchus normally. The calcic precipitation on chorion is likely because absorb the calcium of excessive, contract possibly also as a result of oviduct abnormal be caused by.
5, without yellow egg
Or call small body the egg. This kind of egg and normal egg size differ very great disparity, be equivalent to columbine egg, sparrow egg only so big, lack yoke normally.
Because the eyewinker is like desquamation mucous membrane organization, small cruor piece (as a result of oviposit when follicular haemorrhage be caused by) , the worm in alvine path (also meet sometimes accidental up divide with a hyphen at the end of a line and amount to at oviduct) etc fall into oviduct inside, the albumen of exciting oviduct secretes ministry and uterus, secrete an albumen and chorion, wrap up is in of the eyewinker all round, formed to do not have yolk then without yellow egg, this is accidental coincidence only.
6, double yellow egg and 3 yellow eggs
There are two vitellines to make double yellow egg in an egg, there are 3 vitellines in an egg 3 yellow eggs.
Hen eduction two or the ovum of two above or mature time are too close, oviposit hind encounters to be wrapped together by albumen inside oviduct, form double yellow egg consequently or 3 yellow eggs.
The rate that the hen produces to lay double yellow egg first is a few higher than old hen, because hen constitution is produced first,this is able-bodied, life power is exuberant, oviposit capability is strong. Produce much yellower egg easily also in slink pullet, because chickling chicken sexual organs crosses not complete maturity, cannot control normal oviposit completely.
7, much film egg
Housing film is general only 2, but also have 3, 4, because film of first time carapace is comprised,this is hind, film of go back carapace secretes a ministry, housing film is secreted once more, and formed much film egg.
8, hematic spot egg
After the egg is opened, there is the egg of spot calling blood of clot on yoke, because the oviposit mew blood-vessel of the hen is small,this is broken, blood flows into an egg in, be caught to have hematic silk on yoke. Also have be genetic property.
In feed if lack vitamin K, also can happen. If anus bleeds, the egg that lays, on chorion with hematic spot. Sometimes yoke also has hematic trunk of a tree.
9, fleshy spot egg
After the egg is opened, there is the egg of spot making the pork of fleshy piece on yoke. The reason of egg of occurrence flesh spot is when ovum enters oviduct, epithelial tissue of tubal partial mucous membrane falls off, be defeated by what egg secretes a the coming year to albumen is surrounded and be formed together along with yoke.
Fleshy spot egg and the low yield that spot egg produces afore-mentioned blood at a few young hen sometimes period, but high yield period happens rarely.
10, blood encircles an egg
Ovule dies when hatch development, look carefully at below lamplight, group having blood is seen inside the egg, call blood to encircle an egg.
11, indeterminate form egg
Sometimes the hen can lay a few grotesque eggs, wait like body of top of globose, flat look, chief body, two end, this this formation of unusual egg, basically decide the construction at tubal isthmus and tubal physiology position.
