Preference for bedding material in Syrian hamsters

In a first experiment, 26 male hamsters had access to two connected cages, each cage containing a different bedding material (either pine shavings, aspen shavings, corn cob or wood pellets). In a second experiment, 14 male hamsters had access to...

Role of cage material, working style and hearing sensitivity in perception of animal care noise

During daily care, laboratory animals are exposed to a variety of sounds which may have effects on welfare and also cause physiological and behavioural changes. In this study, sounds from selected rat care procedures were recorded: pulling cage out of...

Individual and group housing in N-type Ca2+ Channel a1B subunit-deficient mice differently affect motor activity

We evaluated the effect of a 6-wk postweaning period of either individual or group housing on the activity displayed in a novel environment with or without previous habituation. Without habituation, male homozygous a1B-deficient mice showed significantly higher activity than wild-type...

Investigation of appropriate sanitization frequency for rodent caging accessories: Evidence supporting less-frequent cleaning

This study provides data relevant to establishing a validated frequency for sanitization of rodent caging accessories while controlling, and potentially decreasing, costs associated with sanitization... The cages were evaluated at several time points from 2 wk to 6 mo. For...

Clinical pathology laboratory values of rats housed in wire-bottom cages compared with those of rats housed in solid-bottom cages

Our laboratory data were evaluated by a board-approved veterinary clincical phathologist, who determined that there were no clincially relevant differences between the two groups.

Effects of light or dark phase testing on behavioural and cognitive performance in DBA mice

Naive DBA/2N (DBA) mice were tested in the modified hole board (mHB) either during the dark phase under red light or during the light phase under white light. Different behavioural dimensions and cognitive functions were evaluated in parallel. Depending on...
