Welfare Assessment

Can the emotional state of calves be noticed by their facial expression and heart rate?

The aim of this study was to identify whether or not dairy calves change their facial expression and heart rate according to their emotional state when subjected to a stroking or umbrella stimulus. Thirty-two mixed-breed Holstein calves of different ages...

Recognising the facial expression of frustration in the horse during feeding period

Horses often present negative emotional states which are frequently poorly recognised, with much of our understanding of horse expressions based on anecdotes, rather than scientific evidence. The aim of this project was to identify potential facial markers of emotional states....

Understanding the behaviour and improving the welfare of pigs

With growing concern from consumers and regulatory agencies about the welfare of farmed animals such as pigs, the livestock sector must assess how animal welfare can be improved whilst ensuring livestock production remains economically and environmentally sustainable. Understanding the behaviour...

Assessing animal welfare with behavior: Onward with caution

An emphasis on ensuring animal welfare is growing in zoo and aquarium associations around the globe. This has led to a focus on measures of welfare outcomes for individual animals. Observations and interpretations of behavior are the most widely used...

In pursuit of peak animal welfare; the need to prioritize the meaningful over the measurable

Despite the diversity of animal welfare definitions, most recognise the centrality of the feelings of animals which are currently impossible to measure directly. As a result, animal welfare assessment is heavily reliant upon the indirect measurement of factors that either...

Decreased levels of discomfort in repeatedly handled mice during experimental procedures, assessed by facial expressions

Mice are the most commonly used laboratory animal, yet there are limited studies which investigate the effects of repeated handling on their welfare and scientific outcomes. Furthermore, simple methods to evaluate distress in mice are lacking, and specialized behavioral or...

RELSA—A multidimensional procedure for the comparative assessment of well-being and the quantitative determination of severity in experimental procedures

Good science in translational research requires good animal welfare according to the principles of 3Rs. In many countries, determining animal welfare is a mandatory legal requirement, implying a categorization of animal suffering, traditionally dominated by subjective scorings. However, how such...

Integrating reference intervals into chimpanzee welfare research

Animal welfare researchers are committed to developing novel approaches to enhance the quality of life of chimpanzees living in professional care. To systematically monitor physical, mental, and emotional states, welfare scientists highlight the importance of integrating non-invasive, animal-based welfare indicators....

Skin cortisol and acoustic activity: Potential tools to evaluate stress and welfare in captive cetaceans

As people's focus broadens from animals on farms to zoos and aquaria, the field of welfare science and the public's concern for animal welfare continue to grow. In captive animals, stress and its causes are topics of interest in welfare...
