Environmental Enrichment

The use of the puzzle box as a means of assessing the efficacy of environmental enrichment

Environmental enrichment can dramatically influence the development and function of neural circuits. Further, enrichment has been shown to successfully delay the onset of symptoms in models of Huntington's disease, suggesting environmental factors can evoke a neuroprotective effect against the progressive,...

Environmental enrichment and social interaction improve cognitive function and decrease reactive oxidative species in normal adult mice

Environmental stimulation and increased social interactions stimulate cognitive performance, while decrease in these parameters can exacerbate cognitive decline as a function of illness, injury, or age. We examined the impact of environmental stimulation and social interactions on cognitive performance in...

Enriched cages for groups of laboratory male rats and their effects on behaviour, weight gain and adrenal glands

We investigated if there were any negative effects on the behaviour and physiology of rats housed in groups of five in two types of enriched cages and compared them with paired-housed rats housed in traditional cages. Eighty-four male Wistar and...

Facts and demonstrations: Exploring the effects of enrichment on data quality

There is widespread support within the scientific community for the concept that better welfare equals better science. It is also broadly accepted that environmental enrichment improves welfare. I have seen much evidence of support for both of these concepts in...

Role of noise and music as anxiety modulators: Relationship with ovarian hormones in the rat

This work aims to verify the role of noise and music as anxiety modulators and their relationship with ovarian hormones. For this purpose, female Wistar rats were used and treated, forming different experimental groups, with 17-β-estradiol, progesterone, allopregnanolone, finasteride (inhibitor...

Enrichment with wood blocks does not affect toxicity assessment in an exploratory toxicology model using Sprague-Dawley rats

Environmental enrichment in rodents may improve animal well-being but can affect neurologic development, immune system function, and aging. We tested the hypothesis that wood block enrichment affects the interpretation of traditional and transcriptomic endpoints in an exploratory toxicology testing model...

Dynamics of the access of captive domestic cats to a feed environmental enrichment item

Providing feed enrichment to captive felids that are obligate carnivores is crucial for eliciting natural hunting behaviours. However, studies of the efficacy of enrichment techniques usually analyse the whole group, overlooking the different behaviours of individual animals towards the enriched...

Let’s stay together: Implications of social housing for laboratory pig welfare and management

Appropriately accommodating the pig's normal social behavior is an essential step in protecting its well-being in managed environments. Doing so is particularly important in laboratory settings in which distress due to social isolation and other factors can introduce unnecessary variability...
