Towards a fully automated surveillance of well-being status in laboratory mice using deep learning: Starting with facial expression analysis

Assessing the well-being of an animal is hindered by the limitations of efficient communication between humans and animals. Instead of direct communication, a variety of parameters are employed to evaluate the well-being of an animal. Especially in the field of...

A ten-stage protocol for assessing the welfare of individual non-captive wild animals: Free-roaming horses (Equus ferus caballus) as an example

Knowledge of the welfare status of wild animals is vital for informing debates about the ways in which we interact with wild animals and their habitats. Currently, there is no published information about how to scientifically assess the welfare of...

Undirected singing rate as a non-invasive tool for welfare monitoring in isolated male zebra finches

Research on the songbird zebra finch (Taeniopygia guttata) has advanced our behavioral, hormonal, neuronal, and genetic understanding of vocal learning. However, little is known about the impact of typical experimental manipulations on the welfare of these birds. Here we explore...

Development of a donkey grimace scale to recognize pain in donkeys (Equus asinus) post castration

The objectives of this study were to establish a donkey ethogram, followed by a donkey grimace scale to be applied to donkeys pre- and post-castration and to test if there was a notable difference in scores based on observer knowledge,...

Validation and utility of a body condition scoring system for chimpanzees (Pan troglodytes)

Obesity is a problem in captive chimpanzee colonies that can lead to increased risk for disease; therefore, implementation of effective weight management strategies is imperative. To properly implement a weight management program, captive managers should be able to noninvasively identify...

Effects of transport conditions on behavioural and physiological responses of horses

The regulations for minimal space and direction of travel for land transport in horses vary worldwide and there is currently no definitive guidance to promote equine health and welfare. This study evaluated the effects of bay size and direction of...

Water pigs! Capybara husbandry in a biomedical research lab

Capybaras, also known as “water pigs,” are the world’s largest rodent. Although these animals are closely related to guinea pigs, with a shoulder height of approximately 2 ft, coarse brown fur, and partially webbed feet, they are unlike any guinea...

Systematic analysis of severity in a widely used cognitive depression model for mice

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 condition. Modern bioethics requires balancing...

Tell-tale TINT: Does the time to incorporate into nest test evaluate postsurgical pain or welfare in mice?

Identifying early indicators of distress in mice is difficult using either periodic monitoring or current technology. Likewise, poor pain identification remains a barrier to providing appropriate pain relief in many mouse models. The Time to Incorporate to Nest Test (TINT),...
