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...

Modification of a dog cage for use as an exercise unit for rabbits

The Guide for the Care and Use of Animals and the USDA Animal Welfare Regulations (AWR) outline minimum space requirements for laboratory animals, including rabbits. These documents encourage housing of animals in enclosures that allow adequate freedom of movement and...

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...

Designing environments for aged primates

In order to prevent physical and psychological deterioration in older animals, it is important to apply the same principles of environmental enrichment and housing as are applied to younger animals. As we have discussed above, the needs of aged individuals...

Factors affecting aggression among females in captive groups of rhesus macaques (Macaca mulatta)

Captive groups of primates often exhibit higher rates of aggression than wild, free-ranging groups. It is important to determine which factors influence aggression in captivity because aggression, particularly intense aggression, can be harmful to animal health and well-being. In this...

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...

Working with what you’ve got: Changes in thermal preference and behavior in mice with or without nest material

In laboratories mice are typically housed at ambient temperatures (Ta) of 20–24 °C, which are below their average preferred Ta of ≈30 °C. Adjusting laboratory Ta is not a solution because preferences differ depending on activity, time of the day,...
