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...

Environmental enrichment inhibits spontaneous apoptosis, prevents seizures and is neuroprotective

Here we show that in addition to its effects on neurogenesis, an enriched environment reduces spontaneous apoptotic cell death in the rat hippocampus by 45%.

A novel method for the supply of bedding and nesting material with inbuilt environmental enrichment for rodents

Non-toxic cellulose tea bag material containing sawdust provided valuable stimulation and encouraged the animals to tear open and dispense the sawdust and utilize the pack as nesting material. The sealed packs were extremely labor saving in storage and dispensing into...

Evaluation of environmental enrichment for laboratory mice

Providing a cage with a preferred nesting material can be a relatively simple method to contribute to the well-being of laboratory mice, without jeopardizing the outcome of experiments. Thus, there seems to be no good reason to deprive laboratory mice...
