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

Use of perches and nestboxes by laying hens in relation to social status, based on examination of consistency of ranking orders and frequency of interaction

, 2001
Four groups of 15-19 adult ISA Brown hens were studied in pens to assess the relationship between social status and use of perches and nestboxes.

Differentially expressed genes for aggressive pecking behaviour in laying hens [PDF]

, 2009
Background Aggressive behaviour is an important aspect in the daily lives of animals living in groups. Aggressive animals have advantages, such as better access to food or territories, and they produce more offspring than low ranking animals.

Reduction of Oxide Inclusions During the High‐Frequency Welding of Steel via a Nonthermal Ar/H2 Plasma Jet

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.

Shell formation and bone strength in laying hens [PDF]

, 2013
In Sweden almost 3.8% of all eggs are ruined due to cracked eggshells as shell quality declines with age during the laying period. This is a concern for food safety as well as an economical problem.

Characterization of miR-200 family members as blood biomarkers for human and laying hen ovarian cancer

, 2020
MicroRNA-200 (miR-200) family is highly expressed in ovarian cancer. We evaluated the levels of family members relative to the internal control miR-103a in ovarian cancer and control blood specimens collected from American and Hong Kong Chinese ...

Synergistic Dual Slip‐Link Toughening of a Water‐Rich Double Network Hydrogel Combining Slide‐Ring and Highly Entangled Networks

Advanced Science, EarlyView.
Two distinct slip‐link mechanisms – the slide‐ring pulley effect and highly entangled chains – are combined in a water‐rich double network hydrogel, achieving synergistic toughening, near‐complete reversibility, and exceptional friction tear resistance at >$>$91 wt.% water.

Innate immunity in chicken lines developed by EMBRAPA Suínos e Aves: antimicrobial activity of macrophages and serum

Revista Brasileira de Zootecnia, 2021
The objective of this study was to compare the antimicrobial activity of macrophages and serum in laying hen (MM, CC, and CCc) and broiler chicken lineages (TT and LL). Macrophages were evaluated for phagocytic and antimicrobial activity.
