Yolk and albumen corticosterone concentrations in eggs laid by white versus brown caged laying hens.
Maternal stress in birds can have permanent transgenerational effects through the transmission of stress hormones to offspring via the egg yolk.

متن کاملDetermining storage related egg quality changes via digital image analysis
The present study was carried out to determine some egg quality characteristics and storage related changes using computer assisted digital image analysis (CADIA) in an 18-month old moulted brown layer (Lohmann Brown) flock. A total of 150 newly laid eggs was randomly divided into two groups: eggs from the control group were broken immediately, while the remainder were stored at 18 C and 55% RH...
متن کاملDi:fferential Viability of Eggs Laid by Queens in Polygyne Colonies of the Fire Ant, Solenopsis Invicta
The viability of eggs laid by individual functional queens from polygyne colonies of the fire ant, Solenopsi:; intricra Buren, was examined by staining for chromatin. In isolation units held in the laboratory inseminated queens laid nearly 100% viable eggs, compared to < 10% for uninseminated queens, Experiments in which the quantity of brood was manipulated demonstrated that the number of broo...
