Social interaction for non-sibling pregnant New Zealand white rabbits on reproductive toxicology

Rabbits are gregarious animals that live in social groups in the wild so individually housing our animals, while meeting the present scientific objectives, restricts their natural social behaviour. How to meet the social needs of our rabbits while maintaining a...

Improving rabbit enrichment: Developing a rolling enrichment plan

A three-week enrichment preference study trialling different substrates, food and pen structures was carried out in three, group-housed female New Zealand White Rabbits (NZW). Preference results: structural - rabbits spent the most time with a circular table (repurposed empty wooden...

Introduction of gang caging for group housed rats

Using an existing gang cage designed for ferrets, we developed a version that would be suitable for housing rats. Caging consisted of 3 floors with a combined floor area of 11620m, connected by 2 ladders. Each individual unit can be...

Assessing the exploratory and anxiety-related behaviors of mice

Ample studies have shown that housing can affect the health, welfare and behavior of mice and therefore, the outcomes of certain experiments. The aim of this study was to investigate if three widely used housing systems, Open Top Cages (OTC),...

Female rats display fewer optimistic responses in a judgment bias test in the absence of a physiological stress response

Metabolic cages are a type of housing used in biomedical research. Metabolic cage housing has been demonstrated to elicit behavioural and physiological changes in rodents housed within them. The nature of this effect has been characterized as anxiogenic. However, few...

Daily travel distances of zoo-housed chimpanzees and gorillas: Implications for welfare assessments and space requirements

The degree to which the relatively smaller area of artificial environments (compared with natural habitats) has measureable effects on the behavior and welfare of captive animals has been debated for many years. While there is little question that these spaces...

The importance of burrowing, climbing and standing upright for laboratory rats

Standard laboratory cages prevent rats (Rattus norvegicus) from performing many behaviours that they perform in the wild, but little is known about how this may affect their welfare. The aims of this study were (i) to record the propensity to...

Captive chimpanzee (Pan troglodytes) behavior as a function of space per animal and enclosure type

Space per animal, or animal density, and enclosure type are important elements of functionally appropriate captive environments (FACEs) for chimpanzees. The National Institutes of Health (NIH) recommends that captive chimpanzees be maintained in areas of >250 ft2/animal. Several studies have...

Automated tracking of motion and body weight for objective monitoring of rats in colony housing

Living together in large social communities within an enriched environment stimulates self-motivated activity in rats. We developed a modular housing system in which a single unit can accommodate as many as 48 rats and contains multiple functional areas. This rat...
