Effects of free-range systems on muscle fiber characteristics and welfare indicators in geese (2025)

Recently, free-range poultry production has increased with notable benefits for animal welfare and meat quality traits. Geese, the third-most productive poultry species, have not been studied extensively. This study investigated the effects of different free-range systems on muscle fiber characteristics...

Thermal imaging in biomedical research: a non-invasive technology for animal models (2025)

Thermal imaging has been used in animal models to non-invasively detect surface temperature changes after several pathologic and surgical processes. Infrared thermography (IRT) identifies increases or decreases in radiated heat according to blood circulation and microcirculation. The present review aims...

Bovine pain scale: A novel tool for pain assessment in cattle undergoing surgery in the hospital setting

Pain negatively impacts animal welfare and it is still neglected in ruminants. This original study aimed to develop and validate the Bovine Pain Scale (BPS) for acute pain assessment in hospitalized cattle undergoing surgery. This was a blinded, randomized, prospective...

Contrafreeloading and its influencing factors in budgerigars (Melopsittacus undulatus): Implications for their feeding and welfare (2025)

Contrafreeloading (CFL) refers to animals' tendency to prefer obtaining food through effort rather than accessing food that is freely available. Researchers have proposed various hypotheses to explain this intriguing phenomenon, but few studies have provided a comprehensive analysis of the...

Effects of access to a well-resourced environment on dairy calf cognition and affective state (2025)

Dairy calves are often raised without maternal contact and in environments of low complexity. Environments that limit natural behaviors are known to impair cognitive development and affective states. We explored the effect of environmental complexity on one measure of social...

The importance of novel and cognitive enrichment for captive chimpanzees (Pan troglodytes) and the use of activity budgets and social network analysis to assess welfare (2025)

I introduced foraging enrichment with a cognitive component to a group of six captive adult chimpanzees living at ZSL Whipsnade Zoo in Dunstable in the United Kingdom. I conducted preliminary behavioural observations for 13 days spread over a four week...

A cross-sectional study to investigate associations between flooring substrates and prevalence of limb and paw abnormalities of dogs housed in commercial breeding facilities (2025)

Understanding the impact of environmental and management factors on the health and behavior of dogs housed in commercial breeding (CB) facilities is critical to their welfare. The specific aims of the study were to assess (a) associations between combinations of...

Exploring the effect of play on heart rate variability as a measure of positive emotional states in pigs (2025)

Play behaviour has been suggested to be inherently rewarding for animals, inducing positive emotional states. The psychophysiological effect of emotions can be assessed through heart rate variability (HRV), serving as a proxy measure of sympathovagal balance. This study investigated how...
