Examining the catching, carrying, and crating process during depopulation of end-of-lay hens
Journal of Applied Poultry Research, 2021 Summary: Laying hen flocks undergo depopulation at end of lay, a difficult process that has been associated with injuries and is considered stressful to hens and human collectors. To date, most assessments of depopulations have been conducted within cage

Optimising the use of hen runs by structures [PDF]
, 2005 One of the main problems in free range husbandry of laying hens is the uneven use of the hen run. This leads to an overuse of pasture near the hen house.

Ammonia Emissions of Laying Hens as Affected by Stocking Density and Manure Accumulation Time [PDF]
, 2010 Different stocking densities (SDs) or space allocations are being practiced in commercial laying-hen operations as an attempt to improve hen welfare. Information concerning the impact of SD on accumulated manure properties (e.g., moisture content) 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.

Advanced Science, EarlyView.We demonstrate that Cars2, a cysteine catabolic enzyme in mouse iBAT, is critical for cold tolerance and brown adipocyte differentiation. Through its CPERS activity, Cars2 produces CysSSH/H2S to induce EBF2 persulfidation, promoting its interaction with PPARγ and BRG1 to enhance thermogenic gene expression.

Dietary Sodium for Laying Hens
Poultry Science, 1977 Dietary sodium requirements of laying hens in open type and evaporatively cooled housing were determined to be 0.126 and 0.145% of the diet, respectively. The lowest level of 0.04% sodium supported average rates of production of 49.1 and 60.3% in the two houses for the 28 weeks of the study.

Assessing ventilation rate measurements in a mechanically ventilated laying hen facility
Poultry Science, 2019 Gaseous emission in laying hen facilities affects animal production performance and the environment. Emission is ruled by gas concentration and ventilation rate (VR), which are the key parameters to estimate precise emission factors.

Search for the ideal laying hen for organic and free range systems [PDF]
, 2011 Since 1960 the majority of commercial layers are housed in cages. Non-cage housing started to appear again from 1980 onwards and increases in importance. It is questionable if birds bred to perform in cages are also suited for free range housing.
