Uterine Metabolomic Analysis for the Regulation of Eggshell Calcification in Chickens
Metabolites, 2021 Eggshell quality is economically important for table eggs and functionally indispensable for hatching eggs. During the formation of eggshell in the uterus, organic matrixes in uterine fluid can control and modify the formation of calcified eggshell.

Correlates of eggshell thickness
Global Journal of Pure and Applied Sciences, 2010 Este estudio discutió los efectos de la edad y el genotipo de las aves y la ubicación de la granja en el grosor de la cáscara de huevo. El objetivo final del estudio es determinar los correlatos del grosor de la cáscara de huevo que pueden ser relevantes para mejorar el grosor de la cáscara de huevo.

Legacy pollutants are declining in Great Skuas (Stercorarius skua) but remain higher in Faroe Islands than in Scotland [PDF]
, 2016 To monitor environmental pollutants in Faroese biota, samples from a top predator were analysed and put into a spatial and temporal context. Analysis of 20 Great Skua eggs sampled in 2012 from the Faroe Islands showed >70 % lower concentrations of ...

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.

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 ...
