Emotion, Pain, & Sentience

Pain management in zebrafish: Report from a FELASA Working Group

Empirical evidence suggests fishes meet the criteria for experiencing pain beyond a reasonable doubt and zebrafish are being increasingly used in studies of pain and nociception. Zebrafish are adopted across a wide range of experimental fields and their use is...

Exploration of skin redness and immunoglobulin A as markers of the affective states of hens

Non-invasive markers of affective states can help understanding animals' perception of situations and improving their welfare. These markers are scarce in avian species. In this study, we investigate the potential relation between alterations in facial skin redness in hens and...

Differences in behaviour, facial expressions and locomotion between positive anticipation and frustration in horses

Animal welfare is a result of accumulated negative and positive emotions. Therefore, it is important to limit the former and promote the latter. Doing so requires a precise identification of these emotions. The aim of this study was to characterize...

The effect of noise, vibration, and light disturbances from daily health checks on breeding performance, nest building, and corticosterone in mice

At our institution, the techniques that technicians use for health checks vary for mice housed in cages on individually ventilated caging (IVC) racks. If the mice cannot be adequately visualized, some technicians partially undock the cage whereas others use an...

Perinatal environmental enrichment changes anxiety-like behaviours in mice and produces similar intergenerational benefits in offspring

Environmental enrichment implemented in early life is able to induce long-term changes in gene expression, synaptic function and behavioural responses. In this study, we evaluated the adult behavioural effects of perinatal environment enrichment in male and female mice (PEE), as...

Measuring emotions in dairy cows: Relationships between infrared temperature of key body parts, lateralised behaviour and milk production

The emotions of cows could be reflected in their body temperature, productivity and behaviours. We tested whether there is a positive correlation between non-invasive infrared temperature (IRT) and right-side laterality (presumed to indicate anxiety), and negative correlation with milk production...

What can associations between emotional states and management-based measures teach us about shelter dogs’ welfare? Journal of Veterinary Behavior 69–70, 32–38

It is crucial to understand the effect of living in a shelter on dog's well-being. We hypothesized that mental states may indicate the presence of environmental stressors. The objective of this study was to determine the relationship between specific emotional...

More exploratory house mice judge an ambiguous situation more negatively

Exploration tendency, one of the most investigated animal personality traits, may be driven by either positive (when seeking interesting information) or negative (to reduce the uncertainty of the environment) affective/emotional profiles. To disentangle the valence of the affective state associated...

Qualitative Behavioural Assessment as a welfare indicator for farmed Atlantic salmon (Salmo salar) in response to a stressful challenge

Animal welfare assessments have struggled to investigate the emotional states of animals while focusing solely on available empirical evidence. Qualitative Behavioural Assessment (QBA) may provide insights into an animal's subjective experiences without compromising scientific rigor. Rather than assessing explicit, physical...

Chronic social comparison elicits depression- and anxiety-like behaviors and alterations in brain-derived neurotrophic factor expression in male rats

Social comparison is a fundamental human characteristic; however, long-term social comparison may induce psychological stress and can lead to depression and anxiety. Recent studies have shown that nonhuman primates compare themselves with others; however, no studies have investigated whether social...
