Risk assessment: Difficult to ensure good animal welfare for exotic birds

VKM (The Norwegian Scientific Committee for Food and the Environment)

Published in 2026

VKM expert report concluding that the welfare needs of many species of parrots and toucans are hard for private aviary owners to meet, notably because of their significant need for flight, social and cognitive stiumlation, enrichment and adapted feed. Seven species are at particularly high risk of poor welfare in captivity.

Stereotypical behaviors across species: From neurobiological mechanisms to farm animal welfare

Chenyang Li, Jie Gao, Hang Shu, Guangyong Zhao, Xianhong Gu

Published in 2026

A review describing stereotypical behaviors—indicators of distress—that are based on neurobiological mechanisms that have yet to be fully studied in farm animals. The authors highlight current gaps in knowledge and discuss prospects for better understanding these behaviors and improving animal welfare.

Integration of computer vision-based behavioral monitoring and machine learning to enhance precision in health and welfare monitoring systems in pig farming

Eddiemar B. Lagua, Hong-Seok Mun, Md Sharifuzzaman, Md Kamrul Hasan, Ahsan Mehtab, Jin-Gu Kang, Young-Hwa Kim, Chul-Ju Yang

Published in 2026

Study showing that computer vision and machine learning are effective in detecting stress-related behaviors in pigs. The models perform very well (especially in binary), but the precise detection of certain states still needs improvement.

The Influence of Environmental Conditions and Husbandry Practices on Goat Welfare

Pilarczyk R., Bąkowska M., Tomza-Marciniak A., Udała J., Seremak B., Kwita E., Sablik P., Pilarczyk B.

Published in 2026

Study showing that goat welfare depends strongly on the environment, diet, and social interactions. Appropriate farming practices (stress management, enrichment, and supervised pain management) and regular assessments significantly improve their welfare, but further research is needed.

Impact of ‘hands-free’ rational handling on operational performance and economic losses in beef cattle

Daniela Costa Cotrim Campos, Adriane Lermen Zart, Claudio Vaz Di Mambro Ribeiro

Published in 2025

Scientific study showing that a cattle-handling protocol designed to reduce stress  significantly reduces bruising and loading times. Economic losses are also lower than those for conventional handling practices. The "hands-free" handling strategy improves operational efficiency without compromising carcass quality.
