Expression analysis for candidate genes associated with eggshell mechanical property
Journal of Integrative Agriculture, 2016 : Damaged eggshells result in losses of eggs. The genetic mechanism of variable eggshell strength is still unclear. The current study was conducted to verify whether the eggshell calcification related genes, CALB1, SPP1, DMP4, BMP2 and SLIT2, were ...

Calcium Homeostasis in Pullets of Two Lines Selected for Differences in Eggshell Strength
Poultry Science, 1979 Abstract Lines were selected from the Cornell K Single Comb White Leghorn strain for two generations for high (HES) or low (LES) eggshell strength. Laying hens of both generations showed significant differences between lines in shell breaking strength.

Influence of the Addition of Eggshell Ash on the Strength of 1:3 Mortars
CerâmicaAbstract This study investigates the effect of incorporating eggshell ash (ESA) into 1:3 mortars and its influence on physical, mechanical, and microstructural properties. Mortars were prepared with 0%, 5%, and 10% ESA additions relative to cement weight. Characterization techniques included XRD, SEM, compressive and flexural strength tests, modulus of
