Key concepts for enhancing zoo animal welfare: Coping, comfort, choice, control, challenge, and compassion

Zoo animal welfare is subject to increasing scrutiny by many audiences. Although zoo husbandry and management techniques have progressed, common welfare issues are still apparent. To encourage further improvements, converting theoretical welfare definition into practical application is key. This paper...

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...

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...

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...

An opportunistic study to assess African green monkey (Chlorocebus sabaeus aethiops) welfare using novel and classical biomarkers

The care and well-being of nonhuman primates (NHPs) in biomedical science have benefited from species-specific enrichment research. However, there remain few publications on African green monkey (AGM) welfare and husbandry. This opportunistic study aimed to explore the use of novel...

Evaluation of welfare indicators for companion parrots: A Delphi consultation survey

Parrots can experience several welfare challenges when kept as companions. Despite their popularity no science-based guidelines are available to assess parrot welfare. The aim of this Delphi study was to establish consensus on welfare indicators that could be meaningful and...

Smart farming and Artificial Intelligence (AI): How can we ensure that animal welfare is a priority?

The increasing use of technology in livestock farming has the potential for making farming easier and more efficient and for improving animal welfare. There are also, however, potential dangers, one of which is that animal welfare becomes subordinated to the...

Assessment of postoperative analgesic efficacy and animal well-being using a novel triaxial accelerometer device, the rodent fitbit-like telemetry device

Accurate postoperative pain management is crucial for good animal welfare and science. We sought to evaluate mouse postoperative pain management efficacy by measuring activity using a novel triaxial acceleration device—the Rodent Fitbit-like telemetry device (RFB)—to monitor home cage activity. To...

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...

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...
