Eggs of hen, Biology
S OF HEN
It is a meiolecithal egg which is oval. The animal pole is found in the form of a small germinal disc.
The vegital pole has two types of yolk viz. White yolk & Yellow yolk.
The white & yellow yolk are found in alternate concentric rings. The outermost ring is of white yolk.
The central part of the vegital pole is flask shaped & contain white yolk. It is called as Latebra. The narrow part of the latebra is called as neck of latebra.
The white yolky region just below the germinal disc is called as nucleus fo pondar.
The yellow yolk is more viscous than the white yolk.
The innermost egg membrane is vitelline membrane which is followed by a chalazeal layer. The chalaza membrane form chalaza on both the sides. The chalaza is a spiral cord which always keeps the germinal disc upside.
The chalazeal layer is followed by three layers of albumin which are called as inner, middle & outer layer of albumin. The middle albumin layer is comparatively thicker.
There are two shell membranes outside the albumin layers which are called as outer & inner shall membranes. Both the shell membranes remain fused except in the broad region where they enclose an air space. The O
present in the air space is used by the embryo during emergency.
The outer most egg membrane covering is called as shell which is madeup of CaCO
& it is porous. It is permeable to gases but impermeable to water.
The oviduct of hen consists of three parts viz. magnum, isthmus & uterus.
The magnum secretes chalazeal layer & albumin layers.
The isthmus secrets the shell membranes. The shell glands of the uterus secrete the shell.
