Confronting crunching: A refinement for the care of mice with the desire to crunch

‘Crunching’ is the term often used to describe the abnormal behaviour of mice that habitually crunch their pelleted diet, causing substrate levels to rise as the crumbs settle on the cage floor ultimately burying the nest. The aim was to...

Refinements to health monitoring

Green, Amber, Red monitoring system: If a mouse shows any of the listed amber signs, then monitoring is increased to either once or twice weekly (green HC). Mice with 3 amber signs should be on red HC (daily check). Mice...

Environmental enrichment for a small colony of rats.

Our facility predominantly houses mice with a small number of rats used for brain cancer studies. Due to limited space and resource for equipment, we came up with some easy and cost effective ways to improve enrichment for the rat...

From Fish to Mice to Monkeys in Research: Challenges and Opportunities for Mental Well-being

This chapter focuses mainly on animals in medical research. Many, especially the smaller species such as rat, mice, and zebrafish, may be seen only a few minutes a day by their human caregivers. Most laboratory animals are kept in confinement...

Personality matters – The interplay between consistent individual differences and mouse welfare in female C57BL6/J mice

To ensure good welfare of animals in human hands, it is essential to modify housing conditions according to the animals’ needs. Traditionally, the effects of such modifications are studied by means of group-level comparisons, thereby widely neglecting consistent inter-individual differences...

Behavioral Biology of Laboratory Animals

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...

Wound localization and housing conditions dictate repair dynamics and scar formation

Wound healing is a highly orchestrated process involving diverse cells and molecular interplays. Although wound healing assays are commonly used in the field of tissue repair, these experiments exhibit high variability due to their multifactorial nature, with many design factors...

Inconsistent terminology in rodent anatomy hinders appropriate blood sampling in laboratory animal science: A review of blood sampling techniques on the head of mice

Blood sampling is often performed during animal studies. This is more challenging in mice than in larger animal species owing to their size and lack of blood vessel visibility. Guidelines for blood sampling in mice and papers on animal welfare...

Mouse strain-specific habituation to oral metamizole administration

When pain might occur during an animal experiment, sufficient analgesia is necessary. Metamizole is the third most used postoperative pain medication in animal research. The analgesic effect of metamizole is supposed to last 6–8 h in rodents. Therefore, the supplementation of...

Breeding planning for laboratory mice

In laboratory animal facilities, due to the rules of mammalian genetics, animals are often produced that do not possess the required genotype for planned experiments. To minimize the number of these animals that cannot be used for the intended research,...
