Environmental Enrichment

Animal-centric Care and Management – Enhancing Refinement in Biomedical Research

The concept of the 3Rs (Refinement, Reduction and Replacement) has been used as a framework for improving the welfare of laboratory animals for the last half century. By establishing an animal-centric view on housing and management, Animal-centric Care and Management:...

Hourly activity patterns and behaviour-based management of feedlot steers with and without a cattle brush

Environmental enrichment (EE) can increase the environmental complexity of feedlots by providing mental and physical stimulation. The objectives of the study were to 1) identify hourly patterns of feedlot steer behaviour and 2) evaluate the impact of EE on these...

Effect of plant-based enrichment materials on exploration in rearing and fattening pigs (Sus scrofa domesticus)

When pigs cannot perform innate species-specific behaviours (e.g. rooting or chewing), behavioural disorders, like tail biting, can occur. However, it seems that various enrichment materials enhance the pigs to perform exploration behaviour and therefore can help to reduce and prevent...

Environmental enrichment facilitates release and survival of an injured loggerhead sea turtle (Caretta caretta) after ten years in captivity

In June 2006 a loggerhead sea turtle (Caretta caretta) was admitted to a rescue centre on the Mediterranean coast with severe fishing net entanglement in its fore right flipper. The flipper could not be saved and was amputated at shoulder...

Music as enrichment for Sumatran orangutans (Pongo abelii)

Music is commonly employed as auditory enrichment in NHP facilities under the assumption that music is as enriching for NHPs as it is for humans (Hinds et al., 2007; Lutz & Novak, 2005). The purpose of this study was to...

Refinement as ethics principle in animal research: Is it necessary to standardize the environmental enrichment in laboratory animals?

The Environmental enrichment technique, although scientifically recognized for raising the level of animal welfare, has led to the questioning of its influence on the results of experimental research. Thus, the goal is to promote reflection about the need for standardization...

Voluntary exercise enhances hippocampal theta rhythm and cognition in the rat

Regular exercise promotes learning and memory functions. Theta activity is known to relate to various cognitive functions. An increase in theta power may be related to higher cognitive functioning and learning functions. However, evidence is lacking to directly confirm that...

Where are you from? Female mice raised in enriched or conventional cages differ socially, and can be discriminated by other mice

Laboratory rodents raised in environmentally-enriched (EE) cages differ behaviourally and cognitively from conventionally-housed (CH) animals. We hypothesised that mice can detect such differences, testing this using differentially-raised female C57BL/6 s as subjects, and differentially-raised female BALB/cs and DBA/2 s as...

Auditory environmental enrichment prevents anxiety-like behavior, but not cortisol responses, evoked by 24-h social isolation in zebrafish

The zebrafish (Danio rerio) is widely used as a promising translational model organism for studying various brain disorders. Zebrafish are also commonly used in behavioral and drug screening assays utilizing individually tested (socially isolated) fish. Various sounds represent important exogenous...

The effects of environmental enrichment on the behaviour of cockatiels (Nymphicus hollandicus) in aviaries

Most research to enrich the environment of psittacines in captivity has focused on foraging. Little is known about the importance of bathing substrates for enrichment of their environment, despite this being a natural behaviour that is rarely possible in captivity....
