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.

Soundboard-trained dogs produce non-accidental, non-random and non-imitative two-button combinations

Bastos, A.P.M., Houghton, Z.N., Naranjo, L., Rossano, F.

Published in 2024

Study suggesting that dogs' use of sound boards to produce words or phrases is neither random nor simple imitatation, but could be intentional. Certain combinations of two-button concepts appear more frequently would be likely if they were random, suggesting that the dogs may be communicating using symbols.

Lighting quality evaluation on growth performance and feather pecking behavior of broilers

Chenghao Pan, Rong Xiang, Jinming Pan

Published in 2025

Study examining the effect of light color on the pecking behavior and growth of Youhuang broilers. Although light did not influence growth, the cold white light group showed more severe plumage damage and lower serotonin levels than the warm white or red light groups. Warm white light is recommended, as it is more user-friendly and limits pecking.

Modèles comportementaux conduisant à la caudophagie

G. Gambarini

Published in 2025

Article on the behavioral variations that characterize tail-biting episodes in pigs.  Two-stage, sudden-violent, and obsessive patterns of behavior each require specific interventions. Early detection, environmental enrichment and reduced competition for resources are essential factors in preventing and managing this behavior.
