PLoS ONE, 2022 Mice respond to a cage change (CC) with altered activity, disrupted sleep and increased anxiety. A bi-weekly cage change is, therefore, preferred over a shorter CC interval and is currently the prevailing routine for Individually ventilated cages (IVCs).

Economic Feasibility in Commercial Egg Production in a Conventional and Cage-Free Systems with Different Stocking Densities [PDF]
Brazilian Journal of Poultry Science, 2022 Adapting existing laying facilities to meet animal welfare certifications is not a simple task. It causes higher expenses to producers, who are often hesitant to accept the need for changes.

Influence of forage substrates on environmental and egg microbiology in cage-free aviary housing
Journal of Applied Poultry Research, 2022 SUMMARY: Within aviary systems, open litter areas are provided to allow hens to express a more robust behavioral repertoire. However, data is limited on the influence forage substrates have on environmental and egg microbiology. The objective of this study was to examine the impact of forage substrates on environmental and egg microbiology in aviary ...

Exploring the relationships between the gut microbiome composition and movement patterns of laying hens in a multitier cage-free housing system. [PDF]
PLoS OneIn this study we investigated the relation between caecal microbiota composition and movement patterns in laying hens. We used hens from Pure line matings of Hendrix Genetics to continuously monitor the movement of individuals in a connected three-tier aviary throughout the laying period, from 18 to 60 weeks of age.

Low levels of chicken body louse (Menacanthus stramineus) infestations affect chicken welfare in a cage-free housing system. [PDF]
Parasit VectorsAbstract Background The chicken body louse is an obligate ectoparasite of domestic chickens. Chicken body lice feed on feathers, and infestation with this louse is linked to decreases in egg production, hen weight, and feed conversion efficiency.

Identification of reliable reference genes for expression studies in the magnum of laying hens housed in cage and cage‐free systems [PDF]
Veterinary Medicine and Science, 2021 Abstract Stress factors during poultry production can evoke changes in gene transcription and protein synthesis in the hen oviduct and could affect the internal and external egg quality. Studies of relative gene expression require the identification of the most stable reference genes for the quantitative ...
