Playing music to animals: An interdisciplinary approach to improving our understanding of animals’ responses to music

Humans have profoundly changed the global soundscape. Studying how nonhuman animals respond to music can contribute to a better understanding of the effect of sound on animals. Animals are frequently exposed to human music, whether intentionally (for example, in laboratory...

Preceding sevoflurane inhalation in rats reduces the stress of intraperitoneal injection both in inexperienced experimenters and subject rats

In this study, we found that sevoflurane inhalation in rats prior to intraperitoneal injection decreased stress in both inexperienced experimenters and subject rats. Inexperienced experimenters anaesthetised male Sprague Dawley rats by intraperitoneal injection of anaesthetics, with or without preceding sevoflurane...

Insights into thermal sensitivity: Effects of elevated temperature on growth, metabolic rate, and stress responses in Atlantic wolffish (Anarhichas lupus)

The Atlantic wolffish (Anarhichas lupus) is a cold-water fish with potential for aquaculture diversification. To unveil the mechanisms underlying the compromised growth in Atlantic wolffish when reared at higher temperatures, we investigated the relationship between temperature, growth rate, aerobic capacity,...

Housing and husbandry factors affecting zebrafish novel tank test responses: A global multi-laboratory study

The reproducibility crisis in bioscience, characterized by inconsistent study results, impedes our understanding of biological processes. Global collaborative studies offer a unique solution to this problem. Here, we present a global collaboration using the zebrafish (Danio rerio) novel tank test,...

Current practices of pain assessment and analgesic use in laboratory mice: A 2022 FELASA Working Group survey

Assessing and alleviating pain in animals involved in research is critically important. However, the effective implementation of pain management depends on the knowledge and attitudes of the personnel involved. Following a Federation of European Laboratory Animal Science Associations ‘Pain in...

A computational model to support the welfare-based management of a laboratory colony of common marmosets

Here, a computational model to forecast the population dynamics of a laboratory colony of common marmosets (Callithrix jacchus) is presented. This tool supports decision-making that seeks to maximize welfare and maintain a healthy and genetically diverse colony. The model considers...

An adaptable, user-friendly score sheet to monitor welfare in experimental fish

Fish are increasingly used as experimental animals across research fields. Currently, around a quarter of all experimental animals used are fish. Less than 20% of these are standard model species. Welfare assessments for experimental fish are in their infancy compared...

The social dimension of equine welfare: Social contact positively affects the emotional state of stalled horses

The housing conditions of domestic animals influence their welfare; their emotional state can be negatively affected if their needs are not met. This can lead to behavioural changes or disorders that can damage the animal–human relationship. In social species such...

Extended oxygen supplementation after thoracotomy in rats may improve welfare

A retrospective comparison of welfare indicators in male rats undergoing thoracotomy for intrapleural dosing is presented. The initial cohort (n = 7) breathed room air after recovery from anaesthesia, while later cohorts (n = 12) had oxygen supplementation for up to 48 h post-surgery....

Insights from the judgement bias paradigm: Social group and tank size do not affect mental state in female guppies

Optimal holding conditions are key to animal welfare. How stressful husbandry is perceived by the animal can be determined via an assessment of an animal’s mental state – where it is positioned on the continuum between optimistic and pessimistic states...
