Identification of reference genes for expression studies in the liver, and spleen of laying hens housed in cage and cage-free systems

Open Veterinary Journal, 2023
Background: The liver and spleen play a pivotal role in metabolism and immune response. During stress, neuroendocrine response induces changes in gene expression and its assessment demands the validation of the stability of the reference genes to perform relative gene expression experiments.

Changes in Serum Protein Profile in Laying Hens Housed in a Cage‐Free System

Veterinary Medicine International
The objective of this study was to characterize the distribution of serum proteins in laying hens reared under cage‐free open farm conditions and to evaluate the changes in the concentrations of serum protein fractions throughout the 1‐year laying period. Ten Dekalb White white‐egg–laying hens were blood sampled from the wing vein at 17, 22, 29, 38, 50,

Use of location tracking to link egg production with toe pecking injuries, feather quality, body mass in laying hens

Journal of Applied Poultry Research
Summary: The current study sought to validate a proxy for egg laying that could be used within cage-free housing systems towards breeding programs of laying hens.

Effect of housing system and age of laying hens on eggshell quality, microbial contamination, and penetration of microorganisms into eggs

Czech Journal of Animal Science, 2018
Hens of the laying hybrid ISA Brown were used in the study with the objective to evaluate eggshell quality, microbial contamination of eggshells, and penetration of microorganisms into the egg content in different housing systems (enriched cage: 60 hens,

The Impact of Eggshell Thickness on the Qualitative Characteristics of Stored Eggs Produced by Three Breeds of Laying Hens of the Cage and Cage-Free Housed Systems

Applied Sciences, 2022
The study aimed to compare the physical-chemical attributes of table eggs from three laying hen breeds housed in the cage and cage-free conditions and to characterize the morphological characteristics of the eggshell interior.

Keratin 19 as a prognostic marker and contributing factor of metastasis and chemoresistance in high‐grade serous ovarian cancer

Molecular Oncology, EarlyView.
Keratin 19 (KRT19) is overexpressed in high‐grade serous ovarian cancer with high levels of Kallikrein‐related peptidases (KLK) 4–7 and is associated with poor survival. In vivo analyses demonstrate that elevated KRT19 increases peritoneal tumour burden.

Multi-tissue transcriptomic profiling reveals the internal physiological landscape of laying hens in cage and cage-free systems

Poultry Science
Welfare-friendly housing systems for laying hens, such as cage-free, have become prevalent. However, the physiological effects of housing systems on the laying hens remain poorly understood. Here, we compared behavioral characteristics and transcriptomic

Emissions of ammonia, carbon dioxide and particulate matter from cage-free layer houses in California [PDF]

Atmospheric Environment, 2017
Abstract Cage-free housing systems have attracted considerable attention in the United States recently as they provide more space and other resources (such as litter area, perches, and nest boxes) for hens and are considered to be more favorable from the standpoint of hen welfare. This study was carried out to quantify emissions of aerial ammonia (NH

CCDC80 suppresses high‐grade serous ovarian cancer migration via negative regulation of B7‐H3

Molecular Oncology, EarlyView.
PAX8 is a lineage‐specific master regulator of transcription in high‐grade serous ovarian cancer (HGSC) progression. We show for the first time that PAX8 facilitates proliferation and metastasis by repressing the cell autonomous tumor suppressor CCDC80 and inducing B7‐H3 expression.

Effects of separated pair housing of female C57BL/6JRj mice on well-being

Scientific Reports, 2022
In laboratory animal facilities, it is a common code of practice to house female mice in groups. However, some experimental conditions require to house them individually, even though social isolation may impair their well-being.
