Female urine-induced ultrasonic vocalizations in male C57BL/6J mice as a proxy indicator for postoperative pain

Objectively recognizing postoperative pain in mice is challenging, making it difficult to determine an appropriate postoperative analgesic regimen. Adult male mice produce ultrasonic vocalizations after exposure to adult female urine (FiUSV). To determine if FiUSV can be used as a...

Frothy saliva—A novel indicator to assess stereotypies in sows?

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 the assessment of stereotypies of...

Grimace scores: Tools to support the identification of pain in mammals used in research

The 3Rs, Replacement, Reduction and Refinement, is a framework to ensure the ethical and justified use of animals in research. The implementation of refinements is required to alleviate and minimise the pain and suffering of animals in research. Public acceptability...

Improvement of the Mouse Grimace Scale set-up for implementing a semi-automated Mouse Grimace Scale scoring (Part 1)

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 results for developing automated and...

Interobserver reliability of measures of the Welfare Quality® animal welfare assessment protocol for sows and piglets

The aim of this study was to assess the interobserver reliability of the measures forming the Welfare Quality® animal welfare assessment protocol for sows and piglets. The study was carried out at nine farms in Northern Germany. Two trained observers...

Investigation of reward quality-related behaviour as a tool to assess emotions

Animals are likely to appraise events as positive or negative based on their subjective perception, current state and past experiences. We tested the effects of anticipating positive (food anticipation), negative (inaccessible food) and neutral (clicker sound) events on behavioural and...

Non-contact vital signs monitoring of dog and cat using a UWB radar

As pets are considered members of the family, their health has received widespread attention. Since pets cannot talk and complain when they feel uncomfortable, monitoring vital signs becomes very helpful in disease detection, as well as observing their progression and...

Non-invasive monitoring of adrenocortical function in female domestic pigs using saliva and faeces as sample matrices

Intensive pig management involves in a commercial setting the housing and implementation of certain procedures, such as castration and tail docking, which may be stressful for the animal. Good farming practices include the reduction of stress due to management processes,...

Pain and problem behavior in cats and dogs

We argue that there is currently an under-reporting of the ways in which pain can be associated with problem behavior, which is seriously limiting the recognition of this welfare problem. A review of the caseloads of 100 recent dog cases...
