The effects of environmental enrichment through larger cage type on behavioral patterns in rats

Most behavioral research is conducted in lab-housed animals due to the significant advantages of a controlled environment. In an effort to enhance the welfare and to obtain more realistic measures of behavior, larger cages with an additional raised platform have...

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.

Solid floors versus wire floor housing for rats revisited: Influence of age and the presence of test boxes

Data did not reveal a clear preference for solid floors. Juveniles were found most often on wire floors while among adults, a preference for solid floors was apparent only in females, and only when a nest box was available.

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...

A European Union-compliant housing environment for nonhuman primates in a toxicology laboratory

As a global company, our institution made the decision to install European Union (EU) Appendix A-compliant nonhuman primate cages at one of its facilities. This investment represented a substantial evolution of standards commonly employed within a North American contract research...

Effects of caging on bone metabolism in cynomolgus monkeys (Macaca mulatta)

Juvenile cynomolgus monkeys are frequently used in drug pharmacokinetic and toxicology testing where they are cage housed for extendeded periods of time. In this study measures of body mass, bone metabolism, and turn over were compared between 2 groups of...

A novel approach for utilizing large group-housing style cages for nonhuman primates in toxicology studies

The ability to provide permanent group-housed caging for nonhuman primates involved in toxicology research is quickly becoming an important step in improving the overall quality of life for these animals. This type of caging offers increased vertical space allowing animals...

Preference of Syrian hamsters to nest in old versus new bedding

This study tested whether Syrian hamsters (Mesocricetus auratus) have an aversion to old bedding (up to 14 days) by offering them the option to nest in a new cage. A secondary goal was to assess the relative value of shelters...
