L’enrichissement du milieu de vie

Céline Tallet and Violaine Colson

Published in 2025

Article on environmental enrichment in captive animals. Conditions in captivity restrict the satisfaction of animals' physiological and ethological needs. Lack of stimulation and stressful practices can be detrimental to their welfare and affect the quality of scientific research carried out on these animals.

Relevance of state-behaviour feedbacks for animal welfare

Montalcini, C.M., Driver, C.C. and Mendl, M.T.

Published in 2025

Scientific review exploring the dynamic interactions between an animal's state (health, emotions) and behavior. These create positive or negative feedback loops that impact animal welfare. The authors propose adjustment strategies that favor positive affective states. The use of dynamic models incorporating longitudinal data is recommended to improve understanding and achieve sustainable improvements in animal welfare.

The neurobiological basis of emotions and their connection to facial expressions in non-human mammals: insights in nonverbal communication

Daniel Mota-Rojas, Alexandra L. Whittaker, Cécile Bienboire-Frosini, Jhon Buenhombre, Patricia Mora-Medina, Adriana Domínguez-Oliva, Julio Martínez-Burnes, Ismael Hernández-Avalos, Adriana Olmos-Hernández, Antonio Verduzco-Mendoza, Alejandro Casas-Alvarado, Karina Lezama-García, Temple Grandin

Published in 2025

Scientific synthesis exploring the emotional sensitivity of non-human mammals, manifested in particular by facial expressions associated with limbic system activity. The AnimalFACS tool, adapted from the human Facial Action Coding System, makes the scientific analysis of these facial movements possible for several animal species. This approach helps to improve the understanding and interpretation of animal emotions, facilitating more accurate non-verbal communication between humans and animals.

Validation of qualitative behaviour assessment for dairy cows at pasture

L. Aubé, M.M. Mialon, I. Veissier, A. de Boyer des Roches

Published in 2025

Scientific article testing Qualitative Behavioral Assessment (QBA) as a means to measure the emotional states of dairy cows on pasture, assessing its reliability and ability to distinguish between different emotional contexts. The results show that QBA is able to identify variations in emotion and arousal, although there is room for improvement in inter-observer reliability.

If you blink at me, I'll blink back. Domestic dogs' feedback to conspecific visual cues

Chiara Canori, Tiziano Travain, Giulia Pedretti, Rachele Fontani, Paola Valsecchi

Published in 2025

Study suggesting that dogs may mimic the eye blinks of other dogs, indicating a potential role in communication. The results also show that these signals do not induce stress, paving the way for further research into their social impact.

Face readers

Christa Lesté-Lasserre

Published in 2025

Article reviewing the multiple potential benefits of AI for the analysis of animals' facial expressions and detection of signs of pain or complex emotions, in which it sometimes performs better than human experts. Researchers are developing algorithms capable of interpreting the emotional states of dogs, cats, horses and primates using deep learning and annotated image databases. However, scientists remain wary of the lack of transparency in the decisions made by AI, and are seeking to combine facial analysis with other indicators to refine the assessment of animal welfare.

Evaluating animal consciousness: An emerging field shows how animal feelings can be studied scientifically

Kristin Andrews, Jonathan Birch, Jeff Sebo

Published in 2025

Article summarizing recent scientific findings on animal consciousness. Although studies on bees, cuttlefish and fish point to signs of consciousness, the latter's acceptance as evidence would have major implications for neuroscience and animal welfare. Meanwhile, the lack of a unified theory or precise definition of animal consciousness complicates its  assessment.

Application of the horse grimace scale in horses with dental disease: Preliminary findings

Amelia E. Sidwell, Marco Duz, Bradley Hill, Sarah Freeman, Sam L. Hole

Published in 2025

Scientific article investigating whether use of a pain scale based on facial expression is an objective and reliable method of assessing dental pain in horses. It concludes that tools designed to identify acute pain lack reliability if used to assess chronic pain, such as dental pain. A more dental-specific ethogram is needed to accurately identify dental pain in horses.
