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.

Observational study: effect of varying transport durations and feed withdrawal on the physiological status and health of dairy calves

van Dijk, Luca L., Siegmann, Susanne, Field, Niamh L., Sugrue, Katie, van Reenen, Cornelis G., Bokkers, Eddie A. M., Conneely, Muireann, Sayers, Gearoid

Published in 2025

Study evaluating the impact of transport and fasting on the physiology and health of unweaned calves. The results show that the physiological changes observed on arrival were related more closely to the duration of feed deprivation rather than that of transport, although muscle fatigue was more marked in calves that had travelled the longest.

Machine Vision Applications for Welfare Monitoring in Aquaculture: Challenges and Opportunities

Fitzgerald, A., Ioannou, C.C., Consuegra, S., Dowsey, A. and Garcia de Leaniz, C.

Published in 2025

Review article examining the practical applications of AI for monitoring animal welfare in aquaculture. Detection of diseases, parasites and stress-related behaviors remains limited, not least because of the practical difficulties of observations on commercial farms. Algorithmic advances such as YOLO could improve the accuracy and adaptability of these systems.

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.
