The application of micro-CT in egg-laying hen bone analysis: introducing an automated bone separation algorithm

open access: yesPoultry Science, 2020
The application of micro-CT in small animal research, especially on bone health, has risen exponentially in recent years. However, its application in egg-laying hen bone analysis was still limited. This review introduces the technical aspects of micro-CT

Oxytocin in the Neurohypophysis of the Laying Hen [PDF]

open access: yesNature, 1960
ALTHOUGH it has been well known that the administration of posterior lobe hormones induces premature oviposit ion in the hen, Gallus domesticus 1,2, as in other fowls3, it remains undetermined whether the hormone(s) plays an essential part in normal oviposition.

Air Quality and Hen Health Status in Three Types of Commercial Laying Hen Houses [PDF]

open access: yes, 2007
Environmental conditions and bird health are important elements in assessment of animal welfare for laying hen housing systems, but limited information is available comparing different types of systems. Three types of laying hen houses - caged high-rise,

High‐Entropy Materials for Water Splitting: An Atomic Nanoengineering Approach to Sustainable Hydrogen Production

open access: yesAdvanced Materials, EarlyView.
High‐entropy materials (HEMs), typically composed of five or more principal elements in near‐equimolar ratios, offer significant potential due to their unique properties. This review outlines the emergence and structural evolution of HEMs, followed by an in‐depth discussion of the elemental roles (active sites, promoters, or stabilizers) for water ...

Chicken white egg chemerin as a tool for genetic selection for egg weight and hen fertility

open access: yesFrontiers in Physiology, 2022
Embryo mortality rate, which can reach up to 40% in avian species, is a major issue for breeding. It is therefore important to identify new embryo development biomarkers for genetic selection to improve reproductive performances.

Phytophthora Disrupts Plant Immunity by Manipulating Nitric Oxide Homeostasis Through GSNOR Inhibition

open access: yesAdvanced Science, EarlyView.
Phytophthora capsici effector PcRD18 targets tomato GSNOR to disrupt NO homeostasis, promoting S‐nitrosylation of immune proteins like RBOHD. This suppresses ROS bursts and promotes pathogen infection. Mutation of the PcRD18‐binding sites of GSNOR avoids pathogen manipulation and offers a strategy to enhance crop resistance. Abstract Nitric oxide (NO),

Effects of Observed Incubation Behavior on Egg Production in Laying Hens of a Commercial Chicken Breed and Detection of Single-Nucleotide Polymorphisms Associated with the Incubation Behavior

open access: yesThe Journal of Poultry Science, 2022
Upon contact with laid eggs, avians initiate incubation behavior and stop laying additional eggs. This phenomenon suggests that the productivity of laying hens in free-range facilities may decrease because of frequent contact with laid eggs.
