Egg colouration in mountain bluebirds (Sialia currucoides): A sexually selected indicator of female quality? [PDF]

, 2015
An adaptive explanation for the blue-green colouration of some avian eggshells has long interested researchers and naturalists alike. Unlike brown and maculated eggs that probably evolved through selection for crypsis, blue-green eggs would likely appear

Egg Quality Effect by Breeder Ages and Egg Storage [PDF]

Journal of Animal and Poultry Production, 2020
The study was conducted to investigate the effects of age of broiler breeder (30 and 45 weeks), storage period (2, 4, 6 and 8 days) and their interactions on egg quality traits of the Ross-308 broiler breeder eggs. The experiment included the measurements of the egg quality characteristics in the research laboratory.

Structure Formation in Butterfly Scales: Interplay of Genetic Control, Mechanical Instabilities, and Dynamic Material Properties

Advanced Functional Materials, EarlyView.
Butterfly wing scales are intricate cuticular functional nanosctructures. This perspective suggests that spatially varying material properties, cytoskeletal constraints, and growth‐driven mechanical instabilities shape the resulting nanoscale architectures created from single cells.

Protein oxidation and its effect on functional properties of livestock products during the processing and storage: A review

Food Chemistry: X
Protein oxidation is a complex chemical process that pervades the entirety of the food domain. It is governed by two primary mechanisms: the direct oxidation by active entities and the indirect oxidation by secondary oxidation byproducts like lipid ...

The chicken embryo and its micro environment during egg storage and early incubation [PDF]

, 2008
When egg storage periods are prolonged (>7 days), hatchability and chick quality declines. The reason for this decline has been investigated, but is still not completely understood.

Co‐Electrospinning Extracellular Matrix with Polycaprolactone Enables a Modular Approach to Balance Bioactivity and Mechanics of a Multifunctional Bone Wrap

Advanced Healthcare Materials, EarlyView.
The incorporation of nondigested ECM and synthetic polymers into a co‐electrospinning system enables the decoupling of bioactivity and mechanical properties within a single wrap. This technique is used to develop a multifunctional bone wrap that achieves augmented membrane durability, sustained infection control, and enhanced vascularity for use in ...

Effects of housing systems, flock variables, and storage conditions on internal egg quality in Israel

Journal of Applied Poultry Research
SUMMARY: The current study aimed to evaluate the internal quality of Israeli eggs, exploring the influence of various pre-laying factors, mainly the housing system type and flock size, on internal egg quality. The study used a stratified random sample of
