Study showing that enrichment of the environment with a novel object reduces non-activity and milking refusals while increasing self-groomimg in dairy cows, indicating that such enrichments can alleviate boredom.

Scientific study identifying several welfare problems in five categories of stabled horses (western riding horses, riding school horses, leisure horses, show jumping horses and endurance horses). Leisure horses received less exercise, and a lack of social contact was observed in 28% of horses in this category.

Summary article describing environmental stress and its negative impacts on rabbit welfare and productivity, causing disease and problem behavior. Environmental enrichment helps reduce this stress by meeting the natural behavioral needs of rabbits, thereby improving their welfare and performance.

Study revealing that cat owners do understand some of their cats' body postures, but with limited accuracy. Female graduates, aged 21 to 40, who spent 1 to 5 hours a day with their cats, were best able to understand the latters' body language. However,the study showed that having owned their cats for a long time and spent long periods of time together were not enough to ensure that owners correctly understood their cats' body language.

Study showing that sows housed in a maternity ring (MR) have better welfare than those in farrowing crates, with fewer frustration-related behaviors and injuries and less medication required for piglets. Assessment using the five-domain framework reveals a more positive emotional state for sows housed in MR.

Study evaluating a tail-biting risk assessment program on 27 pig farms. Results showed little correlation between management practices and tail-biting risk, despite identifying areas for improvement such as stocking density, enrichment provision and incidence of tail docking. The study underscores the need to improve the training of assessors. 

Study combining computer visual monitoring and temperature measurements to monitor the behavior and thermoregulation of 22 pigs exposed to tropical temperatures (ranging from 20.3 to 27.9°C) and thermoneutral conditions (22°C). Pigs exposed to heat stress spent more time lying on their sides to dissipate heat, and a thermal discomfort index (HDI) was created to assess the impact on their welfare.

Study showing that young horses benefiting from daily social interaction during breaking-in show less abnormal behavior and stress than those isolated in individual stalls. The routine integration of social contact improves the welfare and relaxation of horses during training, suggesting that this feature could be beneficial in equestrian centers.

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.

Study revealing that tail docking is still practised despite being banned in Europe, and that weaners with undocked tails are more likely to suffer from bites, especially when transiting through assembly centers prior to slaughter. The carcasses of pigs with tail lesions are more frequently downgraded, underlining the need for new regulations to improve animal welfare.
