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...

The effect of cage size and enrichment on core temperature and febrile response of the golden hamster

Male golden hamsters were studied. The results indicate that housing in small cages induce chronic stress which obviously affects thermoregulation. .... The comparison of the mean values between different sizes of standard cages and between standard and enriched cages of...

Can ‘environmental enrichment’ affect domestic chickens? preferences for one half of an otherwise symmetrical home cage?

The design and assessment of enrichment and husbandry procedures should also take into account the transitory neophobia likely to accompany the introduction of unfamiliar resources.

Influence of environmental enrichment on aggressive behaviour and dominance relationships in growing pigs

The present results show that rearing environments enriched with substrates and extra space improve welfare by directly affecting the social behaviour of pigs. Enrichment significantly reduced aggressive behaviour in a test box and this effect may be extrapolated to any...
