Shelter use in horses: Time spent indoors and factors of variation - Results from a one-year longitudinal study

Léa Lansade, Julie Lemarchand, Alice Ruet

Published in 2025

Study showing that, when horses are free to go indoors or outdoors, they choose to spend an average of 3 hours a day in their stalls, but there is considerable individual and seasonal variability in their choices. These results stress the importance of allowing horses freedom of movement so that their needs and welfare can be better catered to.

Decoding vocal indicators of stress in laying hens: A CNN-MFCC deep learning framework

S. Neethirajan

Published in 2025

Study showing that artificial intelligence, making use of a CNN model combined with MFCC coefficients, can identify vocal responses to stress in laying hens exposed to realistic stimuli with 94% accuracy. Younger birds were found to be more vocally reactive, highlighting the importance of age as a factor in emotional reactivity.

Using deep learning models to decode emotional states in horses

Phelipon, R., Lansade, L. & Razzaq, M.

Published in 2025

Study using machine learning models to predict the emotions of ridden horses on the basis of image analysis, comparing different cropping and training methods for convolutional neural network models. The results showed that cropped images of heads were sufficient to provide very good prediction levels (87% accuracy), and that the features used by the model for interpretation were similar to those used by experts.
