Behavioural Priorities of Laying Hens
Avian and Poultry Biology Reviews, 2003 This article reviews the behavioural requirements of laying hens. It primarily concentrates on evidence from consumer demand studies and relates this to the behavioural and physical consequences of denying hens opportunities to express certain activities.

Magnesium Requirement of the Laying Hen ,
Poultry Science, 1968 Abstract THE quantitative requirement for magnesium by laying hens has not been established. The National Research Council in 1966 listed the growing chicken's requirement as 500 mg. magnesium per kilogram of feed, but gave no estimate of the hen's requirement while Edwards et al. (1961) showed that the phosphorus level of the hen's diet had a marked

Advanced Engineering Materials, EarlyView.High‐frequency (HF) welding of steel is limited by oxide inclusions that degrade weld quality. This study demonstrates, for the first time, the integration of a nonthermal Ar/H2 dielectric barrier discharge (DBD) plasma jet into HF welding. Local plasma treatment provides effective shielding and in‐situ oxide reduction, resulting in markedly fewer and ...

NIBV Induces Incomplete Autophagy via AMPK‐TFEB, Causing Kidney Injury in Chicks
Advanced Science, EarlyView.This study reveals that NIBV can inhibit the nuclear translocation of TFEB by suppressing the expression of AMPK, leading to the blockade of autophagolysosomal functions, in turn increasing NIBV replication and triggering severe kidney injury in chicks.

The Potential of Understory Production Systems to Improve Laying Hen Welfare
Animals, 2022 The welfare of laying hens in cage systems is of increasing concern. Represented by the European Union’s ‘End the Cage Age’ initiative, more and more countries have advocated cage-free farming.
