Evidence-based refinements for chinchillas
In a laboratory setting, it is important to provide housing that allows expression in a wide range of species-typical behaviors while also meeting research goals. Substandard housing can lead to aggression, stereotyping, and anxiety. Understanding the animal’s natural behavior enables us to build quality environments that meet physical, behavioral, and social needs. Proper design is critical for improved health and welfare, both of which improve scientific validity.
Making changes to current housing standards can be challenging especially since facilities may be at very different levels of current housing. Start making small changes from where your facility is currently to improve. Also keep in mind that some of the recommendations below (e.g., providing certain types of environmental enrichment) can change some specific experimental models.
Before implementing housing changes, be sure to consult the relevant scientific literature and consider the requirements of your scientific model. Each facility may require an individual approach to increasing housing standards as much as possible.
Background on the Chinchilla Consortium: The Chinchilla Consortium is a volunteer group of laboratory animal veterinarians, animal resource facility managers, and IACUC professionals from approximately 20 research institutions across the United States. The goals of the Chinchilla Consortium are 3 fold: 1) to identify and support a nationally recognized vendor for the production of purpose-bred, specific pathogen-free chinchillas for biomedical research, 2) support the veterinary and laboratory animal community with reliable knowledge and resources for the veterinary care of chinchillas in a research environment, and 3) to develop and standardize the highest level of husbandry and veterinary care practices across institutions.
