Breeding and maintenance of immunodeficient mouse lines under SPF conditions—A call for individualized severity analyses and approval procedures

In the EU, the breeding of genetically modified laboratory animals is, by definition, an animal experiment if the offspring may experience pain, suffering, or harm. In order to determine the actual burden of genetically modified mice, established methods are available....

Refinement of animal model of colorectal carcinogenesis through the definition of novel humane endpoints

This study aimed to define appropriate humane endpoints (HEs) for an animal model of colorectal carcinogenesis (CRC). Twenty-nine male Wistar rats were divided into two control groups (CTRL1 and CTRL2) injected with ethylenediamine tetraacetic acid (EDTA)–saline solutions and two induced...

Handling mice using gloves sprayed with alcohol-based hand sanitiser: Acute effects on mouse behaviour

Alcohols are commonly used in laboratory animal facilities to disinfect hands, equipment and laboratory environments. The effect on mice is unknown, so we observed male and female C57BL/6J and BALB/c mice during and after handling with nitrile gloves that were...

Methods used and application of the mouse grimace scale in biomedical research 10 years on: A scoping review

The Mouse Grimace Scale (MGS) was developed 10 years ago as a method for assessing pain through the characterisation of changes in five facial features or action units. The strength of the technique is that it is proposed to be...

Social nesting, animal welfare, and disease monitoring

The assessment of welfare and disease progression in animal models is critical. Most tools rely on evaluating individual subjects, whereas social behaviors, also sensitive to acute illness, chronic diseases, or mental health, are scarcely monitored because they are complex and...

Behavioral Biology of Laboratory Animals (1st ed)

This 30-chapter volume informs students and professionals about the behavioral biology of animals commonly housed in laboratory and other captive settings. Each species evolved under specific environmental conditions, resulting in unique behavioral patterns, many of which are maintained in captivity...

Refining housing, husbandry and care for animals used in studies involving biotelemetry

Biotelemetry can contribute towards reducing animal numbers and suffering in disciplines including physiology, pharmacology and behavioural research. However, the technique can also cause harm to animals, making biotelemetry a ‘refinement that needs refining'. Current welfare issues relating to the housing...

Neurobehavioral effects of restricted and unpredictable environmental enrichment in rats

To study how motivational factors modulate experience-dependent neurobehavioral plasticity, we modify a protocol of environmental enrichment (EE) in rats. We assumed that the benefits derived from EE might vary according to the level of incentive salience attributed to it. To...
