Research Note: Changes in eggshell quality and microstructure related to hen age during a production cycle

Poultry Science, 2021
: We have studied in detail the changes that occur in eggshell structure and composition during a production cycle in order to better understand the deterioration of eggshell quality with hen age (at 33, 45, and 67 wk).

The C. elegans eggshell [PDF]

WormBook, 2018
In all animals, oocytes are surrounded by an extracellular matrix upon fertilization. This matrix serves similar purposes in each animal. It functions to mediate sperm binding, to prevent polyspermy, to control the chemical environment of the embryo, and to provide physical protection to the embryo as it developes. The synthesis of the C.

Shell gland RNA-seq reveals key genes regulating eggshell quality and potential links between eggshell quality and hatchability across different laying stages

Poultry Science
The quality of hatching eggs and their hatchability are key factors affecting the production efficiency of breeding flocks. The quality of hatching eggs is commonly graded directly based on the eggshell quality.
