The Effects of Intrauterine Injection with Prostaglandin F2α, Arachidonic Acid and Phosphate Solution on the Eggshell Formation of Japanese Quail Hen

The Journal of Poultry Science, 2002
Inhibitory effects of prostaglandin F2α, arachidonic acid and phosphate solution on the eggshell formation were investigated in Japanese quail. All injections were performed intrauterinely 8h before the predicted oviposition. Prematurely oviposited

Intracrystalline Void‐Mediated Toughening of Brittle Crystals in Quail Eggshells

Advanced Functional Materials, EarlyView.
In quail eggshells, the high density and disordered arrangement of intracrystalline voids inhibit lattice cleavage, suppress long‐range crack propagation, and promote deformation twinning and quasi‐plasticity, serving as an essential toughening motif. We show that these voids remain within a narrow subcritical size range and therefore predominantly do ...

SAMPLING TECHNIQUE THE EGGSHELL THICKNESS

Journal of microbiology, biotechnology and food sciences
The aim of the study was to investigate the shell thickness of table eggs using a destructive method with a focus on the technique of sampling from three locations in the equatorial plane, the sharp and the blunt end of the egg. The subject of the study was the eggshell thickness with membranes of the influence of the sample taken on the egg in ...

First reports on the relationship between the eggshell and bone mineralization in Rhinoclemmys punctularia punctularia embryos

The Anatomical Record, EarlyView.
Abstract Composed of various minerals, the eggshell provides ideal conditions for embryonic development, and understanding its composition and structure is essential for clarifying its relationship with bone formation. This study characterized the structure and mineral profile of the Rhinoclemmys punctularia punctularia eggshell in relation to ...
