Training a large number of laboratory mice using running wheel and analyzing running behavior by use of a compter-assisted system

Using the system, we investigated the running behavior of 21 young C57BL/6 male mice. After the fast growth period, until 8 weeks of age, the mice ran 4 to 5 km/day at an average speed of 23 m/min, and spent...

The early ontogeny of bar-gnawing in laboratory gerbils

Housed in standard cages without lid [no dark areas], gerbils develop stereotyped bar-gnawing already at a very early age.

Age and weight at weaning affect corticosterone level and development of stereotypies in ICR-mice

Artificial weaning in laboratory mice elicits increased levels of exploratory and escape behaviour. Under barren housing conditions patterns of exploration and escape subsequently develop into stereotypic behaviour. .. Both plasma corticosterone levels 48 h after weaning and adult stereotypy levels...

Preferences for nesting material as environmental enrichment for laboratory mice

All [group-housed] mice showed a clear preference for cages with [paper] tissues or [paper] towels as compared to paper strips or no nesting material, and for cages with cotton string or wood-wool as compared to wood shavings or no nesting...

Nesting material as environmental enrichment has no adverse effects on behavior and physiology of laboratory mice

Inanimate enrichment did not affect physiological data but prompted an increase in the animals' body weights.

Oxytocin linked antistress effects–the relaxation and growth response

Stress or noxious stimuli of various kind may induce the fight-flight response. In this situation a number of physiological and behavioural adaptations leading to defense of the organism occur. At a central level increased activity in the noradrenergic locus coeruleus...

Use of in-cage shelters by laboratory rats

Rats with access to an appropriate shelter are more explorative and less timid than those in barren cages.

Behavioural demand functions of caged laboratory mice for additional space

Mice demonstrate a strong motivation to gain access to space additional to that provided by a standard laboratory cage, even when this provides no further resources or enrichment. The importance of a commodity, as perceived by animals, can be determined...
