Welfare Assessment

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

Watters, J. V., Krebs, B. L., Eschmann, C. L. 2021. Assessing animal welfare with behavior: Onward with caution. Journal of Zoological and Botanical Gardens 2(1), 75–87.

An emphasis on ensuring animal welfare is growing in zoo and aquarium associations around the globe. This has led to a focus on measures of welfare outcomes for individual animals. Observations and interpretations of behavior...

Wark, J. D., Cronin, K. A., Niemann, T. et al. 2019. Monitoring the behavior and habitat use of animals to enhance welfare using the zoomonitor app. Animal Behavior and Cognition 6(3), 158–167.

Regular monitoring of the behavior, habitat use, and appearance of animals can provide valuable insight into their welfare. These ongoing data can help identify meaningful trends that can be acted upon to enhance welfare, and...

van der Laan, J. E., Vinke, C. M., Arndt, S. S. 2023. Nocturnal activity as a useful indicator of adaptability of dogs in an animal shelter and after subsequent adoption. Scientific Reports 13(1), 19014.

Dogs in shelters are faced with the challenge of adapting to a kennel after relinquishment and to a novel home after adoption. To measure adaptability of dogs, more feasible behavioural and physiological parameters need to...

Tanaka, Y., Nakata, T., Hibino, H. et al. 2023. Classification of multiple emotional states from facial expressions in head-fixed mice using a deep learning-based image analysis. PLOS ONE 18(7), e0288930.

Facial expressions are widely recognized as universal indicators of underlying internal states in most species of animals, thereby presenting as a non-invasive measure for assessing physical and mental conditions. Despite the advancement of artificial intelligence-assisted...

Serres, A., Robeck, T., Deng, X. et al. 2020. Social, reproductive and contextual influences on fecal glucocorticoid metabolites in captive Yangtze finless porpoises (Neophocaena asiaeorientalis asiaeorientalis) and bottlenose dolphins (Tursiops trun

Although the use of fecal glucocorticoid metabolite (FGCM) measurements as non-invasive biomarkers for the stress response in mammals has increased, few studies have been conducted in odontocetes. We investigated if animal sex, age, pregnancy or...

Serres, A., Delfour, F. 2019. Social behaviors modulate bottlenose dolphins’ (Tursiops truncatus) breathing rate. Animal Behavior and Cognition 6(2), 127–140.

Breathing frequency is a non-invasive physiological measure that brings valuable information on the bottlenose dolphins’ internal state and behaviors. When combined with behavioral observations, it helps to better understand and interpret relevant behaviors. The present...

Schlüns, H., Welling, H., Federici, J. R. et al. 2017. The glass is not yet half empty: Agitation but not Varroa treatment causes cognitive bias in honey bees. Animal Cognition 20(2), 233–241.

Honey bees (Apis mellifera) are prone to judge an ambiguous stimulus negatively if they had been agitated through shaking which simulates a predator attack. Such a cognitive bias has been suggested to reflect an internal...

Sadeghi, M., Banakar, A., Minaei, S. et al. 2023. Early detection of avian diseases based on thermography and artificial intelligence. Animals 13(14), 2348.

Non-invasive measures have a critical role in precision livestock and poultry farming as they can reduce animal stress and provide continuous monitoring. Animal activity can reflect physical and mental states as well as health conditions...

Rose, P. 2023. Identifying essential elements of good giraffe welfare—Can we use knowledge of a species’ fundamental needs to develop welfare-focussed husbandry? Journal of Zoological and Botanical Gardens 4(3), 549–566.

Measurement of zoo animal welfare states enables improvement to husbandry and management to be evidence-based and implemented according to species’ needs. Theoretical welfare concepts are often discussed, and whilst it is helpful to ensure wide...
