Welfare Assessment

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

Chartier, L. C., Hebart, M. L., Howarth, G. S. et al. 2020. Affective state determination in a mouse model of colitis-associated colorectal cancer. PLOS ONE 15(1), e0228413.

Behavioural indicators of affective state, including burrowing, clinical scores and the Mouse Grimace Score have not yet been validated in mouse models of chronic gastrointestinal disease. Additionally, a comparison of these methods has not been...

Ernst, L., Kopaczka, M., Schulz, M. et al. 2020. Semi-automated generation of pictures for the Mouse Grimace Scale: A multi-laboratory analysis (Part 2). Laboratory Animals 54(1), 92–98.

The Mouse Grimace Scale (MGS) is an established method for estimating pain in mice during animal studies. Recently, an improved and standardized MGS set-up and an algorithm for automated and blinded output of images for...

Ernst, L., Kopaczka, M., Schulz, M. et al. 2020. Improvement of the Mouse Grimace Scale set-up for implementing a semi-automated Mouse Grimace Scale scoring (Part 1). Laboratory Animals 54(1), 83–91.

The Mouse Grimace Scale (MGS) has been widely used for the noninvasive examination of distress/pain in mice. The aim of this study was to further improve its performance to generate repeatable, faster, blinded and reliable...

Jirkof, P., Abdelrahman, A., Bleich, A. et al. 2020. A safe bet? Inter-laboratory variability in behaviour-based severity assessment. Laboratory Animals 54(1), 73–82.

Evidence-based severity assessment is essential as a basis for ethical evaluation in animal experimentation to ensure animal welfare, legal compliance and scientific quality. To fulfil these tasks scientists, animal care and veterinary personnel need assessment...

Weegh, N., Füner, J., Janke, O. et al. 2020. Wheel running behaviour in group-housed female mice indicates disturbed wellbeing due to DSS colitis. Laboratory Animals 54(1), 63–72.

Voluntary wheel running (VWR) behaviour is a sensitive indicator of disturbed wellbeing and used for the assessment of individual experimental severity levels in laboratory mice. However, monitoring individual VWR performance usually requires single housing, which...

Mallien, A. S., Häger, C., Palme, R. et al. 2020. Systematic analysis of severity in a widely used cognitive depression model for mice. Laboratory Animals 54(1), 40–49.

Animal models in psychiatric research are indispensable for insights into mechanisms of behaviour and mental disorders. Distress is an important aetiological factor in psychiatric diseases, especially depression, and is often used to mimic the human...

Smith, B. J., Bruner, K., Kendall, L. V. 2019. Female- and intruder-induced ultrasonic vocalizations in C57BL/6J mice as proxy indicators for animal wellbeing. Comparative Medicine 69(5), 374–383.

Female urine-induced male mice ultrasonic vocalizations (FiUSV) are ultrasonic vocalizations produced by adult male mice after presentation of adult female urine, whereas intruder-induced ultrasonic vocalizations (IiUSV) are produced by resident adult female mice when interacting...

Friedrich, L., Krieter, J., Kemper, N. et al. 2020. Frothy saliva—A novel indicator to assess stereotypies in sows? Applied Animal Behaviour Science 222, 104897.

The present study aimed at introducing a reliable and more feasible indicator to evaluate stereotypies in sows in comparison with the ‘Welfare Quality® animal welfare assessment protocol for sows and piglets’. Therefore, the indicators for...

Jorquera-Chavez, M., Fuentes, S., Dunshea, F. et al. 2020. Remotely sensed imagery for early detection of respiratory disease in pigs: A pilot study. Animals 10(3), 451.

Respiratory diseases are a major problem in the pig industry worldwide. Due to the impact of these diseases, the early identification of infected herds is essential. Computer vision technology, using RGB (red, green and blue)...

Vullo, C., Barbieri, S., Catone, G. et al. 2020. Is the Piglet Grimace Scale (PGS) a useful welfare indicator to assess pain after cryptorchidectomy in growing pigs? Animals 10(3), 412.

Pig cryptorchidism is a congenital anomaly, which requires surgical intervention. Pain assessment in pig farming has some limitations and consumers are increasingly concerned about suffering linked to on-farm procedures. The PGS seems to be a...
