The Effect of Eggshell Thickness on Hatching Traits of Partridges [PDF]
Brazilian Journal of Poultry Science, 2016 Incubation is an important factor in poultry production, particularly in species with relatively low fertility and hatchability rates. This study examined the effect of eggshell thickness on hatching traits of partridges (A. chukar).

A Nondestructive Eggshell Thickness Measurement Technique Using Terahertz Waves. [PDF]
Sci Rep, 2020 AbstractEggshells play a number of important roles in the avian and reptile kingdom: protection of internal contents and as a major source of minerals for developing embryos. However, when researching these respective roles, eggshell thickness measurement remains a bottleneck due to the lack of a non-destructive measurement techniques.

Global diversity and adaptations of avian eggshell thickness indices [PDF]
Ibis, 2022 The amniote eggshell is a fundamental aspect of the embryo life‐support system, protecting it from UV light, microbes and mechanical damage, while regulating gas exchange and providing calcium for growth. The thickness of eggshells is highly diverse across modern birds and influences multiple eggshell functions, yet the selective pressures driving ...

Capercaillie (Tetrao urogallus) eggshell pigmentation, maculation and thickness [PDF]
Ornis Fennica, 2018 Eggshells properties (mainly thickness, pigmentation and shape) vary within avian taxa across species, and intraspecifically with age, environmental conditions or individual features of the animals. The properties and appearance of eggshells are important for successful breeding both for birds kept in captivity and in breeding centres and those living ...

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.
