Eggshell Qualities as Indicative of Eggshell Strength for Layer Selection [PDF]
Brazilian Journal of Poultry Science, 2018 The study aimed at investigating which of four traits is the most representative of eggshell strength (destructive eggshell thickness measurement, eggshell weight, egg specific gravity, ultrasonic measurement of eggshell thickness) and could be used for ...

Journal of Clinical Investigation, 2015 The oocyte is the sole source of the female genetic material that will be fertilized by sperm to form an embryo. Many extrinsic and intrinsic factors are critical for oocyte development and survival; however, these mediators are incompletely understood. In this issue of the JCI, Weinberg-Shukron et al. uncover a novel recessive missense mutation in the

Bending Deformation Behavior of Eggshell and Eggshell–Polymer Composites [PDF]
Journal of Composites Science, 2023 Deformation behavior of the composite “eggshell–polymer plomb” was examined under bending. Hen eggs were taken as a biological material for experiments. It was shown that a viscoelastic polymer coating does not change the type of deformation behavior of the composite, given that the eggshell continued to be brittle despite its mechanical ...

The structure of the eggshell and eggshell membranes of Crocodylus niloticus
Journal of Microscopy, 2023 AbstractThe macro‐ and microstructure, elemental composition, and crystallographic characteristics of the eggshell and eggshell membranes of the Crocodylus niloticus egg was investigated using optical and electron microscopy, energy‐dispersive X‐ray spectroscopy (EDS), electron backscatter diffraction (EBSD) and computerised tomography. The translucent

Transcriptomic analysis of the liver in aged laying hens with different eggshell strength
Poultry Science, 2023 : Eggshell is composed of a very ordered and mineralized structure and is important for egg quality. Eggshell strength is particularly important because of its direct association with economic outcomes and egg safety.
