Effect of Dietary Acetylsalicylic Acid on Eggshell Quality
Poultry Science, 1991 Abstract Acetylsalicylic acid (aspirin) is an inhibitor of prostaglandin synthesis. Many soft-shelled (SS) and shell-less (SL) eggs are laid prematurely. It is hypothesized that prostaglandins may be responsible for the premature expulsion of some SS or SL eggs.

Eggshell Quality and Hatchability in Broiler Breeder Eggs ,
Poultry Science, 1987 Abstract Relationships among selected variables of eggshell quality in broiler breeder eggs were determined over complete production cycles in three experiments. Variables measured were egg weight (EW), egg specific gravity (SG), eggshell weight (SW), water vapor conductance (G), and regional pore concentration (PC) and eggshell thickness (ST ...

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT The continuous increasing discharge of synthetic dyes into aquatic systems seems to be an important environmental and health risk due to their high toxicity and resistance to biodegradation. Among these dyes, methylene blue (MB) and Congo red (CR) are widely used in textile and industrial applications, necessitating sustainable and efficient ...

BMC Genomics, 2020 Background Lower eggshell quality in the late laying period leads to economic loss. It is a major threat to the quality and safety of egg products. Age-related variations in ultrastructure were thought to induce this deterioration.

Eggshell spottiness reflects maternally transferred antibodies in blue tits. [PDF]
PLoS ONE, 2012 Blue-green and brown-spotted eggshells in birds have been proposed as sexual signals of female physiological condition and egg quality, reflecting maternal investment in the egg. Testing this hypothesis requires linking eggshell coloration to egg content,

The Anatomical Record, EarlyView.Abstract Stages of embryonic development for reptiles have been presented in tables that may include all or part of embryonic development. When oviposition occurs in some lizards, embryos are already in the later stages of development; likewise, the size of the eggs increases as incubation time progresses.

BMC Genomics, 2021 Background Eggshell is a bio-ceramic material comprising columnar calcite (CaCO3) crystals and organic proteinaceous matrix. The size, shape and orientation of the CaCO3 crystals influence the microstructural properties of chicken eggshells. However, the

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.

Eggshell pigmentation in the blue tit: male quality matters
Behavioral Ecology and Sociobiology, 2017 This study was funded by projects CGL2012-40026-C02-01 to SM and CGL2012-40026-C02-02 to JM from the MEC (Ministerio de Economia y Competitividad). EPB was supported by a JAE grant from the Spanish National Research Council (CSIC).

The Anatomical Record, EarlyView.Abstract A recent debate has emerged between Caspar et al. (2024) and Herculano‐Houzel (2023) on inferring extinct dinosaur cognition by estimating brain neuron counts. While thought‐provoking, the discussion largely overlooks the function of cognition, as well as partly neglects the difficulties involved in estimating neuron numbers, which according ...
