Perch-based enrichment and broiler growth, welfare and behaviour

B. F. Sevinç B. Yılmaz Dikmen

Published in 2026

Study showing that perch-based enrichment does not affect growth or most welfare windicators in broiler chickens, but that it reduces hock burn and slightly improves locomotion.

Animal welfare indicators and stress response of broiler chickens raised at low and high stocking density

Chan Ho Kim, Ki Hyun Kim, Ju Lan Chun, Se Jin Lim, Jung Hwan Jeon

Published in 2025

Study showing that lower stocking densities in broiler chickens improve welfare (drier litter, less foot dermatitis, lower corticosterone) and feed efficiency, despite slightly lower feed intake and body weight.

How do domestic chickens perceive humans—and why does it matter?

Ferreira, V. H. B., Lansade, L., Calandreau, L.

Published in 2025

Scientific review showing that chickens have developed socio-cognitive capabilities that enable them to perceive human attentional states, distinguish between individual humans, and interpret human social cues, with direct implications for their welfare and farming practices.

Advancements in machine learning applications in poultry farming: a literature review

Naeem M, Jia Z, Wang J, Poudel S, Manjankattil S, Adhikari Y, Bailey M, Bourassa D

Published in 2025

Review highlighting the potential of machine learning to optimize poultry production, improve animal welfare and detect disease at an early stage using sophisticated predictive and monitoring tools. It does, however, highlight the challenges surrounding the quality and interpretation of data and models, and their use on the ground.

Impacts of Reduced Stocking Density on Broiler Welfare During Transport: Evidence from a Hungarian Study Under Moderate Climatic Conditions

László Szőllősi, Dániel Fróna, Laura Mihály-Karnai, Attila Csorbai

Published in 2025

Hungarian study showing that the reduction in  the transport density of broiler chickens recommended by the EFSA to improve their welfare can nevertheless result in higher mortality, and more injuries and condemned carcasses. The results suggest that increasing the space allowance does not necessarily improve welfare under moderate temperature conditions and that further research is required.

Systematic Review of Acoustic Monitoring in Livestock Farming: Vocalization Patterns and Sound Source Analysis

Ramos Niño JN, Sousa FCd, Oliveira CEA, Coelho ALdF, Hernandez RO, Barbari M.

Published in 2025

Systematic review showing that environmental sounds and animal vocalizations have promise as non-invasive indicators of animal welfare. Despite technological advances, challenges remain in terms of standardization, physiological validation and practical application under real-life commercial conditions.
