Welfare Assessment

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

Whitham, J. C., Miller, L. J. 2016. Using technology to monitor and improve zoo animal welfare. Animal Welfare 25(4), 395-409.

While the international zoological community is committed to enhancing the welfare of individual animals, researchers have yet to take full advantage of the tools available for non-invasively tracking behavioural and physiological indicators of welfare. We...

Viksten, S. M., Visser, E. K., Nyman, S. 2017. Developing a horse welfare assessment protocol. Animal Welfare 26(1), 59-65.

This paper describes the development and pilot-testing of a horse welfare assessment protocol (HWAP). The HWAP consists of the collective measurement of numerous factors considered likely to affect a horse's welfare and is thereby designed...

Clegg, I. L. K., van Elk, C. E., Delfour, F. 2017. Applying welfare science to bottlenose dolphins (Tursiops truncatus). Animal Welfare 26(2), 165-176.

Animal welfare science is a burgeoning field, but research on cetaceans (whales, dolphins and porpoises) is lacking. Bottlenose dolphins (Tursiops truncatus) are the most well-known and studied cetaceans, particularly in captivity, and thus are used...

Chadwick, C. L., Williams, E., Asher, L. et al. 2017. Incorporating stakeholder perspectives into the assessment and provision of captive elephant welfare. Animal Welfare 26(4), 461-472.

Recent concerns over the welfare of elephants in UK zoos have implications for their future in captivity, and it is clear that improvements in welfare should be made. Evidence suggests that the knowledge of experienced...

Guesgen, M. J., Bench, C. 2017. What can kinematics tell us about the affective states of animals? Animal Welfare 26( 4), 383-397.

An animal's welfare state is intrinsically linked to its affective state. Evidence suggests that sentient, conscious animals can experience a range of affective states, such as pain, fear or boredom as well as positive affects...

Leeds, A., Lukas, K. E. 2018. Experimentally evaluating the function of self-directed behaviour in two adult mandrills (Mandrillus sphinx). Animal Welfare 27(1), 81-86.

Given the difficulties of conducting regular endocrine and veterinary assessments of animals, behavioural observations are often the most commonly used tool to assess the welfare of animals in human care. Behavioural measures, inexpensive and convenient...

Casey-Trott, T. M., Widowski, T. M. 2018. Validation of an accelerometer to quantify inactivity in laying hens with or without keel-bone fractures. Animal Welfare 27(2), 103-114.

Accelerometers are used to remotely monitor activity in various species in studies that quantify pain, document behavioural patterns, and measure individual activity differences. Studies validating accelerometers typically quantify various active states; however, targeting states specific...

Souza, A., Soriano, V. S., Schnaider, M. A. et al. 2018. Development and refinement of three animal-based broiler chicken welfare indicators. Animal Welfare 27(3), 263-274.

This study aimed to refine bird-soiling as a broiler chicken (Gallus gallus domesticus) welfare indicator, and to develop and test two additional indicators, namely contact dermatitis on the breast and abdominal areas and carcase scratches...

Williams, E., Chadwick, C. L., Yon, L. et al. 2018. A review of current indicators of welfare in captive elephants (Loxodonta africana and Elephas maximus). Animal Welfare 27(3), 235-249.

Concerns over elephant welfare in UK zoos have implications for their future in captivity. To monitor improvements made to elephant welfare in UK zoos, non-invasive, valid and reliable indicators of welfare are needed. Using a...

Monk, J. E., Doyle, R. E., Colditz, I. G. et al. 2018. Towards a more practical attention bias test to assess affective state in sheep. PLOS ONE 13(1), e0190404.

Tests for attention bias potentially offer more rapid assessment of affective state in animals than existing cognitive methods. An attention bias test has previously been developed for sheep and validated as a measure of anxious...
