Welfare Assessment

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

Fermo, J. L., Schnaider, M. A., Silva, A. H. P. et al. 2019. Only when it feels good: Specific cat vocalizations other than meowing. Animals 9(11), 878.

Our objective was to identify and characterize the types of vocalization other than meowing (VOM) in two contexts, a pleasant and an aversive situation, and to study the effect of the sex of the animal...

Lawrence, A. B., Vigors, B., Sandøe, P. 2019. What is so positive about positive animal welfare?—A critical review of the literature. Animals 9(10), 783.

It is claimed that positive animal welfare (PAW) developed over the last decade in reaction to animal welfare focusing too much on avoiding negatives. However, it remains unclear what PAW adds to the animal welfare...

Mattiello, S., Battini, M., De Rosa, G. et al. 2019. How can we assess positive welfare in ruminants? Animals 9(10), 758.

Until now, most research has focused on the development of indicators of negative welfare, and relatively few studies provide information on valid, reliable, and feasible indicators addressing positive aspects of animal welfare. However, a lack...

Brscic, M., Dam Otten, N., Contiero, B. et al. 2019. Investigation of a standardized qualitative behaviour assessment and exploration of potential influencing factors on the emotional state of dairy calves. Animals 9(10), 757.

Assessing emotional states of dairy calves is an essential part of welfare assessment, but standardized protocols are absent. The present study aims at assessing the emotional states of dairy calves and establishing a reliable standard...

Watters, J. V., Krebs, B. L. 2019. Assessing and enhancing the welfare of animals with equivocal and reliable cues. Animals 9(9), 680.

The actions of human caretakers strongly influence animals living under human care. Here, we consider how intentional and unintentional signals provided by caretakers can inform our assessment of animals' well-being as well as help to...

George, R. P., Howarth, G. S., Whittaker, A. L. 2019. Use of the rat grimace scale to evaluate visceral pain in a model of chemotherapy-induced mucositis. Animals 9(9), 678.

The rat grimace scale (RGS) is a measure of spontaneous pain that evaluates pain response. The ability to characterize pain through a non-invasive method has considerable utility for numerous animal models of disease, including mucositis...

Merkies, K., Ready, C., Farkas, L. et al. 2019. Eye blink rates and eyelid twitches as a non-invasive measure of stress in the domestic horse. Animals 9(58), 62.

Physiological changes provide indices of stress responses, however, behavioural measures may be easier to determine. Spontaneous eye blink rate has potential as a non-invasive indicator of stress. Eyelid movements, along with heart rate (HR) and...

Battini, M., Agostini, A., Mattiello, S. 2019. Understanding cows' emotions on farm: Are eye white and ear posture reliable indicators? Animals 9(8), 477.

Understanding the emotions of dairy cows is primarily important in enhancing the level of welfare and provide a better life on farm. This study explored whether eye white and ear posture can reliably contribute to...

Larsen, M. L. V., Pedersen, L. J., Jensen, D. B. 2019. Prediction of tail biting events in finisher pigs from automatically recorded sensor data. Animals 9(7), 458.

Tail biting in pigs is an animal welfare problem, and tail biting should be prevented from developing into tail damage. One strategy could be to predict events of tail biting so that the farmer can...

Marcet-Rius, M., Fàbrega, E., Cozzi, A. et al. 2019. Are tail and ear movements indicators of emotions in tail-docked pigs in response to environmental enrichment? Animals 9(7), 449.

The inclusion of emotional indicators in farm monitoring methods can improve welfare assessments. Studies in controlled conditions have suggested that increased tail movement is an indicator of positive emotions in pigs, while others have proposed...
