Impact of euthanasia on compassion fatigue in personnel working in animal research

We conducted a cross-sectional study to investigate the association between euthanasia and compassion fatigue among employees working in animal research at a large academic medical center. In summary, animal research workers who euthanize animals reported significantly more burnout and traumatic...

Impact of flooring type on the sham dustbathing behaviour of caged laying hens

Feed particles are preferred for foraging and they are also a stimulus for sham dustbathing. Most sham dustbathing bouts start with bill raking in the feed by caged hens. As hens often exhibit a floor scratching behaviour, an element of...

Impact of three commonly used blood sampling techniques on the welfare of laboratory mice: Taking the animal’s perspective

Laboratory mice are the most frequently used animals in biomedical research. In accordance with guidelines for humane handling, several blood sampling techniques have been established. While the effects of these procedures on blood quality and histological alterations at the sampling...

Investigating the function of mutual grooming in captive bonobos (Pan paniscus) and Chimpanzees (Pan troglodytes)

Social grooming is often exchanged between individuals in many primate species. Rates of bidirectional (or simultaneous mutual) grooming vary across primate species, and its function is not yet fully understood. For example, mutual grooming is frequent in chimpanzees but rare...

Investigation of reward quality-related behaviour as a tool to assess emotions

Animals are likely to appraise events as positive or negative based on their subjective perception, current state and past experiences. We tested the effects of anticipating positive (food anticipation), negative (inaccessible food) and neutral (clicker sound) events on behavioural and...

Is that a rat in your pocket? A novel pocket method for rat restraint

At the University of Illinois at Urbana- Champaign (UIUC), we routinely teach novice research personnel how to appropriately handle, restrain, and perform basic experimental techniques on rats. Barriers to teaching include fear of animal bites to the handler, stress to...

Isoflurane and carbon dioxide elicit similar behavioral responses in rats

Euthanasia in rodents is an ongoing topic of debate due to concerns regarding the aversive nature of gases with anesthetic properties such as carbon dioxide (CO2) and isoflurane. The aim of this study was to expand upon previously published work...
