Benefits of providing nesting material as a from of environmental enrichment for mice

Husbandry conditions in a laboratory environment can be barren and monotonous. Improving those conditions by providing opportunities for laboratory mice to engage in species-specific behavior can improve their mental and physical well-being. Giving the animals choices and control over their...

Housing, care and accommodation: An inspector’s observation on how these can affect rodent welfare

In my view it is vitally important that scientists and management pay attention to what animal technologists and care staff have to say about the care and requirements of experimental animals.

Effects of environmental enrichment and housing system on weight gain of C57BL/6 mice

Our goal was to evaluate the effect of treatment represented by enrichment with cotton balls, and the housing system, by comparing the conventional (open cage) and the ventilated cage (IVC) systems on the weight gain of C57BL/6 inbred mice, as...

Noise in a laboratory animal facility from the human and mouse perspectives

The current study was performed to understand the level of sound produced by ventilated racks, animal transfer stations, and construction equipment that mice in ventilated cages hear relative to what humans would hear in the same environment. Although the ventilated...

Effects of access to voluntary wheel running on the development of stereotypy

Stereotyped motor behaviors are a common consequence of environmental restriction in a wide variety of species. Although environmental enrichment has been shown to substantially reduce stereotypy levels, the various components of enrichment have not been evaluated independently to determine which...

Effects of specific environmental enrichment contributing to litter size and attrition rate of TRP1/TGfβ transgenic mice in a breeding colony

In previous studies of environmental enrichment of mice it has been determined that certain types of mice are affected by manipulation of their living environment. Some have effects on cognitive memory and some affect the developmental nurturing on second and...

Middle-aged mice with enrichment-resistant stereotypic behaviour show reduced motivation for enrichment

For captive animals, living in barren conditions leads to stereotypic behaviour that is hard to alleviate using environmental enrichment. This resistance to enrichment is often explained via mechanisms that decouple abnormal behaviour from current welfare, such as "establishment": a hypothetical...

Effects of increased interaction between research rodents and their handlers

We conclude that handling experimental animals more often than only at the time their cage is changes is beneficial.

Clinical biochemistry parameters in C57BL/6J mice after blood collection from the submandibular vein and retroorbital plexus

Collection of blood from the submandibular vein allows simple and rapid processing of many animals without anesthesia and facilitates rapid recovery with no signs of pain and discomfort in the mice. Here we compared the submandibular vein and retroorbital plexus...

Evaluation of nesting materials for use in nude mouse colonies

Nesting material has been reported to be beneficial to mice by providing environmental enrichment as well as a means of thermoregulation. Cotton nesting material has been reported to cause conjunctivitis in athymic nude mice. We evaluated 3 different paper-based nesting...
