Horses Prefer Their Rider: A Strange Situation Test Adaptation Shows Behavioural Evidence for Partner-Specific Bonding

B.A. Kovács, J. Topál, A. Gergely

Published in 2026

A study showing that horses exhibit closeness to and a preference for their riders, suggesting the existence of a particular social bond, but without clear evidence that this reassures them when they are presented with stressors.

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.

Measuring shade use of dairy cattle at pasture with an on-cow light sensor: a case study

Lydiane Aubé, Bruno Meunier, Romain Lardy

Published in 2026

Study confirming the effectiveness of using a light sensor attached to grazing cows to automatically detect whether they are in the shade or in the sun. The technique works well and allows continuous monitoring of the cows' use of shade.

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.

Behavior recognition of tail and ear biting in pigs using AI-based computer vision

Qinghua Guo, Clémence A.E.M. Orsini, Patrick P.J.H. Langenhuizen, Yue Sun, Shoujun Huo, Lisette E. van der Zande, Inonge Reimert, J. Elizabeth Bolhuis, Piter Bijma, Peter H.N. de With

Published in 2026

Study demonstrating the feasibility of video-based automated monitoring of tail and ear biting on commercial farms. A computer vision-based model (MViTv2-S) achieves approximately 72% accuracy without having to rely on detection of specific postures, paving the way for early-warning systems and breeding selection strategies to reduce these harmful behaviors.

Do pigs like to brush? An observational study of pig brushing behavior in a commercial production environment

Niclas Högberg, Lena Skånberg, Oleksiy Guzhva, Rebecka Westin, Axel Sannö, Anna Wallenbeck, Maria Vilain Rørvang

Published in 2025

First study to describe the brushing behavior of pregnant sows. The results show that they voluntarily use a mechanical brush, suggesting that this equipment may be an appropriate form of enrichment for the welfare of pigs on farm.

Play in Fattening Pigs: Prevalence and Potential as an Indicator of Positive Welfare

Puttkammer N., Czycholl I.

Published in 2025

Scientific study showing that play behaviors increase in pigs at the end of the fattening period, but that certain types of play, particularly play with objects, are difficult to interpret, leading to the recommendation that locomotor play should be considered a more reliable and usable welfare indicator.
