Temporal Variations of Air Quality in Cage-Free Experimental Pullet Houses

Poultry, 2023
The welfare of laying hens in conventional caged houses has become an increased public concern, leading primary food chains, restaurants, and grocers in the United States to pledge to source only cage-free (CF) eggs by 2025 or 2030. Cage-free housing systems have been considered as a more humane alternative; however, they still come with certain ...

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.

Hen genetic strain and extended cold storage influence on physical egg quality from cage-free aviary housing system

Poultry Science, 2018
In the United States, there is an increase in need for cage-free eggs in retail and food manufacturing sectors. Understanding the impact of cage-free systems and the corresponding management on egg quality is pertinent as the U.S. industry adapts existing housing and builds new cage-free housing structures. A study was conducted comparing 2 brown shell

U.S. Consumer Preferences for Cage‐Free Eggs and Hen Housing Policies

Agribusiness
ABSTRACTFarm animal welfare (FAW) continues to be a divisive issue in the egg industry. In the United States, 10 states and most major retailers have implemented policies or voluntary pledges to transition to 100% cage‐free egg sales. We use best‐worst scaling and discrete choice experiments to evaluate U.S.

Impacts of Excreta Exposure and Age on Ileal Microbial Communities, Intestinal Permeability, and Corticosterone in Hens Housed in Enriched Colonies and Cage-Free Housing Systems

Poultry
To tease apart differences between conventional cage (CC) and cage-free (CF) housing systems, this study focuses on the effects of excreta exposure and age by comparing microbial communities, intestinal permeability, and corticosterone in hens in ...
