DEVELOPMENT OF CHICKEN EGGS UP hatch

It's good veterinary world as a human being , the more we understand about how the development of eggs from day to day until the chick hatches .

The period of incubation for 21 days is a very critical period for determining the birth of a chick . The embryo in the egg 's extraordinary tumbuhsecara every day until eventually hatch into chicks .

Broadly speaking , from the literature expressed in embryonic development during the 21 days of incubation until the end so tiny chicks ( DOC or Day Old Chicken ) process as

On day 1 the beginning of a number of cell formation process began. Cells permulaanuntuk digestive system begins to form at the 18th hour . on the hour - jamberikutnya , respectively up to the 24th hour , starting jugaterbentuk cells beginning to brain tissue , cells beginning to jaringantulang behind , the formation of the relationship between brain tissue and nerve tissue , formation of the head , cell starters for blood , and formation syarafmata beginning .

On the 2nd day of the embryo begins to shift to the left side , and blood vessels begin to look padabagian yolk. Cell development from the 25th hour to hour - 48secara sequence is the formation of small blood vessels danjantung , whole brain tissue begins to form , the lining of the fluid starts to look , and began also formed the formation throat .

Then on the 3rd day of the commencement of the formation of the nose , wings , legs , and jaringanpernafasan . At this time , the liquid membranes also cover the entire bagianembrio .

Furthermore, on the 4th day of cells beginning on the tongue begins to form. At this time , the embryo terpisahseluruhnya of yolk and turned to the left . Meanwhile , jaringansaluran respiratory visible from across the membrane fluid .

Then on day 5 of the digestive tract and began to form cache . At this time terbentukpula reproductive tissues . Therefore already started can also be determined jeniskelaminnya .

Then the 6th day beak formation begins . Likewise with legs and wings . In addition , the embryo begins to do the movements .

The next day the 7th , 8th , and 9th toes and wings look began to take shape . In addition, the stomach began to stand out as jeroannya began to develop. The formation of feathers also begins . In this period , the embryo is like a bird , and his mouth looks mulaimembuka .

When the 10th and 11th beak begins to harden , the toes have started completely separated, danpori -pore body began to appear .

When the day - to - toe 12Jari already formed completely and the first feathers start to appear 

13th day and 14th scales and toenails begin to form. The body was already sepenuhnyaditumbuhi feathers. On day 14, the embryo rotates so that his head tepatberada at the dulling of the egg.

Day15 intestinal tissue begins to form in the body of the embryo.

The time of day the 16th and 17th scales feet, nails and beak hardened. Sudahsepenuhnya embryo body covered with hair that grows. The egg white is no longer there, dankuning eggs increased function as food very pentingbagi embryo. In addition, half of the already leading to an air bag cavity, the lining of the fluid began to decrease, and the embryo begins to make preparations untukbernafas.

When the 18th and 19th of embryo growth has been close to perfect. Egg yolks begin masukke the abdominal cavity through the umbilical cord channel. Embryos are also increasingly besarsehingga already fills the entire cavity of the egg unless the air bag cavity.

Kala 20th day yolk has entered fully into the body of the embryo. Yanghampir embryo into these chicks through the membrane fluid, and began bernafasmenggunakan air in the air bag. Danbekerja airways begin to function perfectly.

Finally the day-to-21Anak chicken eggs penetrate the skin layer and hatch into DOC.
