Effect of Uniformity of Eggshell Thickness on Eggshell Quality in Chickens
The Journal of Poultry Science, 2014 Numerous parameters have been proposed to evaluate eggshell quality in order to reduce losses from damaged eggshells. The uniformity of eggshell thickness (UET), as a newly proposed parameter, is defined as the reciprocal of the coefficient of variation

Modelling Eggshell Maculation [PDF]
Avian Biology Research, 2015 The eggshells of many avian species are characterised by distinctive patterns of maculation, consisting of speckles, spots, blotches or streaks, the spatial-statistical properties of which vary considerably between (and often within) species. Understanding the mechanisms underlying the production of eggshell maculation would enable us to explore the ...

Evolution of the Avian Eggshell Biomineralization Protein Toolkit – New Insights From Multi-Omics
Frontiers in Genetics, 2021 The avian eggshell is a remarkable biomineral, which is essential for avian reproduction; its properties permit embryonic development in the desiccating terrestrial environment, and moreover, are critically important to preserve unfertilized egg quality ...

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.
