Environmental enrichment may alter the number of rats needed to achieve statistical significance

The aim of this study was to evaluate whether two enrichment items, an aspen tube and block, have any impact on commonly analysed clinical chemistry and physiological parameters of Wistar rats and - more importantly - on the extent of...

The use of aspen blocks and tubes to enrich the cage environment of laboratory rats

Female and male outbred Wistar rats (n=48) were allocated into three groups at weaning; control, tube and block groups (n = 8 males and 8 females in each) Animals were conventionally housed for five weeks in groups of four per...

Peanut butter bombs: An enrichment device for captive chimpanzees

To work the peanut butter and treats from the [destructible plastic] bottles, chimpanzees often fashioned and used tools. ... After the chimpanzees had removed all of the enrichment inside [food treats in peanut 'coated' bottle], the destructible plastic bottles also...

Strain-specific effects of cage enrichment in male laboratory mice (Mus musculus)

The relationship between aggression, testosterone and 'enrichment' [clear Perspex tunnel and a small handful of shredded tissue] suggest that increasing complexity in laboratory cages may increase a naturally selected territorial response in some strains. ... Enrichment, as used in this...

Practical rodent enrichment

We have designed and evaluated two forms of rodent enrichment: (1) Floor feeding, where in addition to the standard diet present in the cage hopper, other food is mixed into the cage substrate; (2) A cage insert, which incorporates a...
