Uterine Metabolomic Analysis for the Regulation of Eggshell Calcification in Chickens

open access: yesMetabolites, 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.

Sustainable cement replacement using waste eggshells: A review on mechanical properties of eggshell concrete and strength prediction using artificial neural network

open access: yesCase Studies in Construction Materials, 2023
Though the European Commission classifies eggshell as a hazardous material, using eggshell powder in place of cement can aid in waste reduction and contribute to sustainability initiatives. Eggshell powder replaces cement in concrete manufacturing due to

Research Note: L*a*b* color space for prediction of eggshell pigment content in differently colored eggs

open access: yesPoultry Science, 2022
: Eggshell color is the most intuitive external feature that affects consumer acceptance. Different eggshell colors are mainly determined by protoporphyrin IX and biliverdin content. The selection of eggshell color by the human eye with an eggshell color

Comparison between different breeds of laying hens in terms of eggshell translucency and its distribution in various ends of the eggshell

open access: yesPoultry Science, 2021
: Eggshell translucency is a ubiquitous external eggshell quality problem caused by variations of eggshell ultrastructure or shell membrane. In previous studies, researchers have widely investigated this phenomenon with nutritional, environmental, and ...

Poreless eggshells [PDF]

open access: yesJournal of Clinical Investigation, 2015
The oocyte is the sole source of the female genetic material that will be fertilized by sperm to form an embryo. Many extrinsic and intrinsic factors are critical for oocyte development and survival; however, these mediators are incompletely understood. In this issue of the JCI, Weinberg-Shukron et al. uncover a novel recessive missense mutation in the

Bending Deformation Behavior of Eggshell and Eggshell–Polymer Composites [PDF]

open access: yesJournal of Composites Science, 2023
Deformation behavior of the composite “eggshell–polymer plomb” was examined under bending. Hen eggs were taken as a biological material for experiments. It was shown that a viscoelastic polymer coating does not change the type of deformation behavior of the composite, given that the eggshell continued to be brittle despite its mechanical ...

Meta-analysis of studies on eggshell concrete using mixed regression and response surface methodology

open access: yesJournal of King Saud University: Engineering Sciences, 2023
Eggshell concrete is an innovative green material that helps to recycle eggshell waste while reducing the environmental harm caused by excessive cement production. However, recent studies on eggshell concrete are limited, and the outcomes may vary due to

Using eggshell membranes as a DNA source for population genetic research [PDF]

open access: yes, 2009
In the context of population genetic research, a faster and less invasive method of DNA sampling would allow large-scale assessments of genetic diversity and genetic differentiation with the help of volunteer observers.
