Welfare Assessment

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

Blois-Heulin, C., Rochais, C., Camus, S. et al. 2015. Animal welfare: Could adult play be a false friend? Animal Behavior and Cognition 2(2), 156–185.

There is no consensus regarding the functions of play. As play behavior is a characteristic of young stages of development, it has been suggested that the higher prevalence of adult play observed in domestic animals...

Beer, H. N., Karr, L. K., Shrader, T. C. et al. 2023. Allostatic load index effectively measures chronic stress status in zoo-housed giraffes. Journal of Zoological and Botanical Gardens 4(3), 623–636.

For giraffes, few standardized methods exist for quantifying chronic stress. Allostatic load index is quantified from a panel of multi-system stress biomarkers to estimate cumulative stress. Our objective was to determine whether a panel of...

Barnard, S., Matthews, L., Messori, S. et al. 2016. Laterality as an indicator of emotional stress in ewes and lambs during a separation test. Animal Cognition 19(1), 207–214.

We assessed motor laterality in sheep to explore species-specific brain hemi-field dominance and how this could be affected by genetic or developmental factors. Further, we investigated whether directionality and strength of laterality could be linked...

Ataallahi, M., Cheon, S. N., Park, G.-W. et al. 2023. Assessment of stress levels in lactating cattle: Analyzing cortisol residues in commercial milk products in relation to the temperature-humidity index. Animals 13(15), 2407.

Chronic stress in the dairy cattle industry has negative impacts on animal health, productivity, and welfare. It has been confirmed that cortisol transfers to milk and resists the high temperature during milk processing. This study...

Andrade, M. P., Santos, C. M. D., De Paiva, M. M. M. et al. 2023. Assessing negative welfare measures for wild invertebrates: The case for octopuses. Animals 13(19), 3021.

Welfare metrics have been established for octopuses in the laboratory, but not for octopuses living in the wild. Wild octopuses are constantly exposed to potentially harmful situations, and the ability to assess the welfare status...

Alvarado, M. V., Felip, A., Espigares, F. et al. 2023. Unexpected appetitive events promote positive affective state in juvenile European sea bass. Scientific Reports 13(1), 22064.

Some animal species exhibit considerable physiological and behavioural alterations in response to captivity. It has been hypothesized, but rarely tested, that such changes reflect a negative affective state that is associated to this specific context...

Palacio, S., Zambelis, A., Adam, S. et al. 2023. Reassessing cow comfort measures on Canadian dairy farms after a recommendation of improvements. Canadian Journal of Animal Science 103(2), 174–184.

In a previous study (Assessment 1), an on-farm assessment tool was used to establish a standard across 60 Quebec dairy farms using animal-, stall-, and management-based measures of cow comfort. The objective of the present...

Jain, A. K., Tansey, G., Hartig, R. et al. 2023. Trends and treatment approaches for complications in neuroscience experiments with monkey species. Comparative Medicine 73(3), 216–228.

Our goal in this manuscript is to advance the assessment and treatment of monkey species in neuroscience research. We hope to begin a discussion and establish baseline data on how complications are identified and treated...

Imsland, A. K. D., Berg, M. S., Haugland, G. T. et al. 2022. Comparing body density of lumpfish (Cyclopterus lumpus) to different operational welfare indicators. Fishes 7(5), 284.

Farmed lumpfish (Cyclopterus lumpus) are commonly used as cleaner fish in the salmonid aquaculture industry, but a knowledge gap exists with regards to their body density. Filling this knowledge gap is of importance, as the...
