Transcriptome analyses of shell color and egg production traits between the uteruses of blue-green eggshell chickens and Hy-Line brown layers

Poultry Science
Blue-green eggs exhibit unique shell color; however, compared to commercial layers, blue-green eggshell chickens have lower egg production and lack uniform shell colors.

Genome-Wide Association Study Reveals Candidate Genes Associated With the Intensity of Green Eggshell Color in Chickens. [PDF]

Anim Genet
Eggshell color is an important economic trait in poultry. In green‐eggshell chickens, eggshell color intensity is primarily determined by the amount of biliverdin deposited in the shell, but its genetic basis remains unclear. In this study, 230 Dongxiang

Mechanisms associated with the depigmentation of brown eggshells: a review

Poultry Science, 2021
: Eggshell color is an important shell quality trait that influences consumer preference. It is also of particular importance with respect to sexual signaling and the physiological and mechanical properties of shell pigment.

Mitochondrial transcription factor A induces the declined mitochondrial biogenesis correlative with depigmentation of brown eggshell in aged laying hens

Poultry Science, 2021
Eggshell color is an important characteristic for poultry eggs. Eggs from aged hens usually have poor shell color that is unacceptable for the table egg market.

Molecular and morphological analyses of avian eggshell excavated from a late thirteenth century earth oven [PDF]

, 2011
Using ancient DNA (aDNA) extracted from eggshell of the extinct moa (Aves: Dinornithiformes) we determined the species composition and number of eggs found in a late thirteenth century earth oven feature at Wairau Bar (South Island, New Zealand) - one of

Eggshell appearance does not signal maternal corticosterone exposure in Japanese quail: an experimental study with brown-spotted eggs [PDF]

, 2013
Reproduction is a critical period for birds as they have to cope with many stressful events. One consequence of an acute exposure to stress is the release of corticosterone, the avian stress hormone.

Insights Into mRNA and Long Non-coding RNA Profiling RNA Sequencing in Uterus of Chickens With Pink and Blue Eggshell Colors

Frontiers in Veterinary Science, 2021
The blue egg is both of biological interest and economic importance for consumers, egg retailers, and scientists. To date, the genetic mechanisms underlying pigment have mainly focused on protein-coding genes.
