Effect of different LED light colors on welfare, performance, some behavioral patterns, and blood parameters of Muscovy ducks

Eman Hefnawy, Eman Elgazzar, Ahmed Sabek, Saeed El-laithy, Souad Ahmed

Published in 2024

Study evaluating the impact of different LED light colors on the welfare of Muscovy ducks. Blue light proved particularly beneficial, reducing feather pecking, tonic immobility time, and cortisol levels, while it improved feather condition without affecting growth.

Determination of Equine Behaviour in Subjectively Non-Lame Ridden Sports Horses and Comparison with Lame Sports Horses Evaluated at Competitions

Sue Dyson, Danica Pollard

Published in 2024

Scientific study using the Ridden Horse Pain Ethogram (RHpE), developed to assess musculoskeletal pain in competition horses. The study shows that horses participating in lower-level events show higher RHpE scores, manifesting more signs of pain, compared to those at higher levels. Recognizing these behaviors can improve horse welfare and rider safety.

Machine learning-based understanding of aquatic animal behaviour in waters

Ignacio Martinez-Alpiste, Jean-Benoît de Tailly, Jose M. Alcaraz-Calero, Katherine A. Sloman, Mhairi E. Alexander, Qi Wang

Published in 2024

Scientific paper proposing an automated method for real-time monitoring of shrimp behavior, using an instance segmentation system based on machine learning. This system, which is 89% accurate at 30 fps, provides a way to overcome the challenges of working in harsh underwater environments, facilitating biological investigations and improving automated aquaculture systems.

Effects of different rooting materials on behaviour and welfare of finishing pigs

Ellen Marie Rosvold, Marko Ocepek, Inger Lise Andersen

Published in 2024

Scientific article comparing the effects of different foraging materials on pig behavior and welfare. The results suggest that straw and hay are highly valued by pigs compared with pellets, peat and sawdust, and that weekly rotation of materials provides the greatest stimulation.

The odour of an unfamiliar stressed or relaxed person affects dogs' responses to a cognitive bias test

Z. Parr-Cortes, C. T. Müller, L. Talas, M. Mendl, C. Guest, N. J. Rooney

Published in 2024

Scientific article confirming that dogs can discriminate between human odors emitted during positive or negative emotions with no other cues. The results also show that olfactory signals of human stress affect dogs' behaviors when approaching a bowl of food placed in an ambiguous location and may affect their learning.
