Mitigating Particulate Matter Generation in a Commercial Cage-Free Hen House

Transactions of the ASABE, 2019
Abstract. Compared to conventional cage production systems, cage-free (CF) hen housing offers hens more space and opportunities to exercise their natural behaviors (e.g., perching, dust bathing, and foraging). However, CF housing poses a number of inherent environmental challenges, among which are high levels of particulate matter (PM) and ammonia (NH3)

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 ...

Assessing Environmental Mitigation Strategies in Controlled Cage-Free Aviary Housing Systems: Effect on Air Quality and Bioaerosols

Journal of the ASABE, 2023
Highlights Three mitigation strategies were tested in experimental chambers fitted as small-scale aviaries. Particle monitor and high-flow air samplers were used to sample airborne dust (PM) and bioaerosols.

The Impacts of Stocking Density on Behavior of Pullets Reared in Cage-free Housing Systems

2023
There is a clear need for more research detailing how to manage birds in cage-free housing systems. Although management guides for birds in cage-free systems focus on adult hens, previous research has established that the pullet phase is important to success later in life.
