Eggshell pigment composition covaries with phylogeny but not with life history or with nesting ecology traits of British passerines [PDF]
, 2015 No single hypothesis is likely to explain the diversity in eggshell coloration and patterning across birds, suggesting that eggshell appearance is most likely to have evolved to fulfill many nonexclusive functions.

Genome-wide association study exploring the genetic architecture of eggshell speckles in laying hens
BMC Genomics, 2023 Background Eggshell speckle phenotype is an important trait in poultry production because they affect eggshell quality. However, the genetic architecture of speckled eggshells remains unclear.

Transcriptomic analysis of the liver in aged laying hens with different eggshell strength
Poultry Science, 2023 : Eggshell is composed of a very ordered and mineralized structure and is important for egg quality. Eggshell strength is particularly important because of its direct association with economic outcomes and egg safety.

Microfocus X-ray scattering investigations of eggshell nanotexture [PDF]
, 2005 The avian eggshell is a highly ordered calcitic bioceramic composite, with both inorganic and organic constituents. The interactions between the inorganic and organic components within the structure are poorly understood but are likely to occur at the ...

Optimization of Separation Process of Eggshell and Shell Membrane
Shipin gongye ke-ji, 2023 The two must be separated first to exploit the eggshell and the eggshell membranes. In this paper, a combination of mechanical crushing, water flotation and dilute acid treatment was used for shell membrane separation, and the conditions of eggshell and ...

Eggshell structure, measurements, and quality-affecting factors in laying hens: a review
Czech Journal of Animal Science, 2016 Eggshell quality is one of the most significant factors affecting poultry industry; it economically influences egg production and hatchability. Eggshell consists of shell membranes and the true shell that includes mammillary layer, palisade layer, and ...

Genetic variation in eggshell crystal size and orientation is large and these traits are correlated with shell thickness and are associated with eggshell matrix protein markers [PDF]
, 2012 The size and orientation of calcium carbonate crystals influence the structure and strength of the eggshells of chickens. In this study, estimates of heritability were found to be high (0.6) for crystal size and moderate (0.3) for crystal orientation ...
