Includes refinements to diet, bedding or flooring, cage changing, lighting, temperature, noise levels, etc.
Captive rhesus macaques sometimes exhibit undesirable abnormal behaviors, such as motor stereotypic behavior (MSB) and self-abuse. Many risk factors for these behaviors have been identified but the list is far from comprehensive, and large individual...
Our institution opened the Jan and Dan Duncan Neurologic Research Institute (NRI) in November of 2010. This facility houses a team of world renowned researchers working with mice and rats to develop treatments for childhood...
This article discusses how behavioral management, enrichment structures, diet, and light cycle can be used to help improve the welfare of zebrafish.
Several behavioral interventions, based on social enrichment and observational learning are applied in treatment of neuropsychiatric disorders. However, the mechanism of such modulatory effect and the safety of applied methods on individuals involved in social...
Although human subjects are widely used to study sleep and sleep disorders, animals have been invaluable in developing our understanding of the physiology of sleep and underlying mechanisms of sleep disorders. Environmental stimuli are likely...
The environment in which a laboratory animal is housed can significantly influence its behaviour and welfare, acting as a potential confounding factor for those studies in which it is utilised. This study investigated the impact...
Free-access stalls allow sows to choose the protection of a stall or use of a shared group space. This study investigated the effect of group space width, 0.91 (SS), 2.13 (IS), and 3.05 (LS) m...
We are committed to ensuring all our animals have the highest level of care and welfare. To this end, our social housing program includes placing all animals in pairs or groups. We have a rate...
This work aims to verify the role of noise and music as anxiety modulators and their relationship with ovarian hormones. For this purpose, female Wistar rats were used and treated, forming different experimental groups, with...
The number of flooded cages per cage change cycle (14 days) was tracked and it was identified that leaks and flooding often times occurred shortly after cage changing. To reduce the occurrence of flooded caging...
