Welfare Assessment

Includes methods and protocols to monitor or assess animal health, pain, and other emotions.

Schütz, A. K., Krause, E. T., Fischer, M. et al. 2022. Computer vision for detection of body posture and behavior of red foxes. Animals 12(3), 233.

The behavior of animals is related to their health and welfare status. The latter plays a particular role in animal experiments, where continuous monitoring is essential for animal welfare. In this study, we focus on...

Augustine, L., Baskir, E., Kozlowski, C. P. 2022. Investigating welfare metrics for snakes at the Saint Louis zoo. Animals 12(3), 373.

Modern herpetoculture has seen a rise in welfare-related habitat modifications, although ethologically-informed enclosure design and evidence-based husbandry are lacking. The diversity that exists within snakes complicates standardizing snake welfare assessment tools and evaluation techniques. Utilizing...

Mainau, E., Llonch, P., Temple, D. et al. 2022. Alteration in activity patterns of cows as a result of pain due to health conditions. Animals 12(2), 176.

The main conditions and diseases considered painful in dairy cows are mastitis, lameness, calving (including dystocia and caesarean section) and metritis. The cattle literature reports that deviation from normal daily activity patterns (both increased and/or...

Miller, A. L., Roughan, J. V. 2021. Welfare assessment, end-point refinement and the effects of non-aversive handling in C57BL/6 mice with Lewis lung cancer. Animals 12(1), 23.

Cancer-bearing mice are at risk of developing anxiety, pain, or malaise. These conditions may not only harm welfare but could also undermine data quality and translational validity in studies to develop therapeutic interventions. We aimed...

Hewitt, L., Small, A. 2021. Welfare of farmed crocodilians: Identification of potential animal-based measures using elicitation of expert opinion. Animals 11(12), 3450.

Animal-based measures are the measure of choice in animal welfare assessment protocols as they can often be applied completely independently to the housing or production system employed. Although there has been a small body of...

Vaz, J., McElligott, A. G., Narayan, E. 2022. Linking the roles of personality and stress physiology for managing the welfare of captive big cats. Animal Welfare 31(1), 99-111.

Animal welfare is important for the humane treatment of animals under our care. Zoos and rescue centres manage various charismatic animals, such as big cats, with limited resources. It is therefore essential for caretakers to...

Paul, E. S., Browne, W., Mendl, M. T. et al. 2022. Assessing animal welfare: A triangulation of preference, judgement bias and other candidate welfare indicators. Animal Behaviour 186, 151-177.

To assess the welfare of captive animals, validated measures, so-called ‘welfare indicators’, are required. We used a triangulation approach to investigate the extent to which different measures converged to provide corroborating evidence of welfare. Laying...

Sabrautzki, S., Miller, M., Kague, E. et al. 2021. Welfare assessment of adult laboratory zebrafish: A practical guide. Zebrafish 18(4), 282-292.

Teleost fish such as Danio rerio (zebrafish) have been successfully used in biomedical research since decades. Genetically altered fish lines obtained by state-of-the-art genetic technologies are serving as well-known model organisms. In Europe, following Directive...

Thatcher, D. 2021. The use of a borescope for Goodfellow’s tree kangaroo (Dendrolagus goodfellowi) husbandry. RATEL (Journal of the Association of British and Irish Wild Animal Keepers) 48(2), 10-11.

In 2017 Bristol Zoological Gardens received two Goodfellow tree kangaroos. As this was a new marsupial species for the collection, keepers attended the European Symposium on tree kangaroos to better improve our husbandry, knowledge and...

Edes, A. N., Brand, C. M. 2021. Age, sex, and inflammatory markers predict chronic conditions, cardiac disease, and mortality among captive western lowland gorillas (Gorilla gorilla gorilla). Primates 62(6), 931-943.

In humans, inflammatory markers predict health risks. As great apes experience many similar conditions, measuring inflammation may provide valuable health information. We examined four serum inflammatory markers in zoo-housed gorillas (n = 48): albumin, CRP, IL-6, and...
