Microfocus X-ray scattering investigations of eggshell nanotexture [PDF]
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 ...

Legacy pollutants are declining in Great Skuas (Stercorarius skua) but remain higher in Faroe Islands than in Scotland [PDF]
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 ...

The Effect of Indomethacin on Eggshell Quality
The objective of the present study was to determine whether indomethacin, an inhibitor of prostaglandin synthesis, could improve shell quality in birds laying a high incidence (greater than 15%) of soft-shelled (SS) and shell-less (SL) eggs and in birds laying exclusively hard-shelled (HS) eggs. Treatments consisted of two injection types, indomethacin

The Effects of Egg Shape Index on Egg Quality Traits of Guinea Fowl (Numida meleagris)
The aim of this study was to investigated the effects of the egg shape index on egg quality characteristics in Guinea fowl. For this, the eggs were classified in terms of egg shape index, as ≤ 75, < 76 -77 > and ≥ 78. A total of 100 Guinea fowl eggs were

Extracellular Matrix Molecules of the Eggshell as Related to Eggshell Quality [PDF]
The extracellular matrix of the mineralizing eggshell contains molecules hypothesized to be regulators biomineralization. To study eggshell matrix molecules, a bank of monoclonal antibodies was generated that bound demineralized eggshell matrix or localized to oviduct epithelium.
