Numerical Simulation of Airborne Disease Spread in Cage-Free Hen Housing With Multiple Ventilation Options

Animals, 2022
The current ventilation designs of poultry barns have been present deficiencies with respect to the capacity to protect against disease exposure, especially during epidemic events. An evolution of ventilation options is needed in the egg industry to keep pace with the advancing transition to cage-free production.

Characterization of the Eukaryotic Microbial Communities in the Chicken Ileum in Cage-Free and Conventional Commercial Housing Systems

Poultry Science, 2023
The current shift from conventional cage (CC) hen housing facilities towards cage-free (CF) hen housing in the egg industry has left many questions regarding how level of fecal exposure and exposure to other hens may influence the hen intestinal microbiota.

Microbiome and Biological Blood Marker Changes in Hens at Different Laying Stages in Conventional and Cage Free Housings

Poultry Science, 2020
With the majority of conventional cage (CC) laying facilities transitioning into cage-free (CF) systems in the near future, it is important to characterize biological markers of health in layers housed in commercial housings for sustainable production.

Egg Production and Welfare of Laying Hens Kept in Different Housing Systems (Conventional, Enriched Cage, and Free Range)

Poultry Science, 2016
The aim of this study was to compare egg production performance and welfare traits of laying hens kept in conventional cage (CC), enriched cage (EC), and free range (FR). Lohmann Brown laying hens (n = 480 with 160 per housing type) were studied across a

Freeing the Hens: Workshop Outcomes for Applying Ethology to the Development of Cage-Free Housing Systems in the Commercial Egg Industry

Applied Animal Behaviour Science, 2022
Throughout the world, most laying hens producing eggs for human consumption are still kept in small, wirebattery cages. Ethologists have well documented the behavioural needs of hens, and the way that battery cageconfinement thwarts highly motivated behaviour and reduces hens’ quality of life.

Fan and Ventilation Rate Monitoring of Cage-Free Layer Houses in California

Transactions of the ASABE, 2018
Abstract. Ventilation rates were continuously monitored from 1 March 2012 to 13 May 2013 in two cage-free layer houses in California. The average number of brown Lohmann laying hens in each house was 33,300. Temperature, relative humidity, static pressure, and running status of 48 ventilation fans were continuously monitored and recorded every minute ...
