Shell gland RNA-seq reveals key genes regulating eggshell quality and potential links between eggshell quality and hatchability across different laying stages [PDF]

Poultry Science
The quality of hatching eggs and their hatchability are key factors affecting the production efficiency of breeding flocks. The quality of hatching eggs is commonly graded directly based on the eggshell quality.

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.

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

Case 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

Poultry 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

Poultry 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 ...
