Developing and validating attention bias tools for assessing trait and state affect in animals: A worked example with Macaca mulatta

Attention bias is a new approach to assessing animal affect that has shown promising results in several animal species. It describes a tendency to preferentially attend to emotional compared to neutral cues and is influenced by underlying affect. It is...

Development of existing scoring systems to assess behavioural coping in shelter cats

Assessing how cats cope with the housing and husbandry at shelters is an important part of maintaining good animal welfare. There are non-invasive methods to assess how cats cope with their environment. The aim of this study was to investigate...

Exploring stable-based behaviour and behaviour switching for the detection of bilateral pain in equines

Efficient and sensitive animal pain detection approaches are increasingly studied with the goal of improving animal welfare and monitoring the efficacy of treatment and rehabilitation. The aim of this study was to determine the potential of various behaviours as sensitive...

Addressing stress in dogs in shelters through a novel visual and auditory enrichment device

Dogs experience both acute and chronic stress when living in animal shelters. Current best practices recommend a variety of techniques for reducing stress such as enhanced human interactions including play or training, novel feeding strategies, increased exercise/group play, and, when...

Pupil size variation as a response to stress in European catfish and its application for social stress detection in albino conspecifics

Hormonal changes such as increased cortisol level in blood plasma in response to stress and social environmental stimuli are common among vertebrates including humans and typically accompanied by other physiological processes, such as changes in body pigmentation and/or pupil dilatation....

Anticipatory behaviour as an indicator of the welfare of dairy calves in different housing environments

Anticipatory behaviour occurs in the period before a reward or other positive event is presented and has been interpreted as an indicator of the welfare and emotional state of animals. The use of this indicator has received limited attention in...

Opportunities for refinement in neuroscience: Indicators of wellness and post-operative pain in laboratory macaques

Being able to assess pain in nonhuman primates undergoing biomedical procedures is important for preventing and alleviating pain, and for developing better guidelines to minimize the impacts of research on welfare in line with the 3Rs principle of Refinement. Nonhuman...

Hypothermia during general anesthesia interferes with pain assessment in laboratory rats (Rattus norvegicus)

Accurate pain assessment methods are necessary to ensure animal welfare and reliable data collection in animal research. The Rat Grimace Scale (RGS), a facial expression pain scale, allows effective identification of pain. However, the potential confounds of this method remain...

Identification of sick or dead mice (Mus musculus) housed with 6 grams of crinkle paper nesting material

Although nesting material is beneficial to the welfare of laboratory mice, provision of appropriate amounts may impair visualization of the mice. In anticipation of our academic research institution transitioning to providing 6 grams of nesting material to all mice, we...
