Environmental Enrichment

Shelter-style environmental enrichment affects neurobehavioral status of laboratory mice

Environmental enrichment aims to improve the wellbeing of laboratory animals and provides an opportunity to improve experimental reliability and validity. Animals raised in more stimulating environments have improved learning and memory as well as more complex brain architecture. However, the...

Designing gum-based enrichment for captive patas monkeys (Erythrocebus patas)

In the wild, patas monkeys (Erythrocebus patas) consume Acacia spp. gum for 20% of their active time. While providing gum-based enrichment to other gummivorous primates is not a unique idea, there have been no reports of captive patas monkeys receiving...

History of enrichment in the ILAR Guide for the Care and Use of Laboratory Animals

Throughout the nearly 50 year history of the Institute for Laboratory Animal Research (ILAR) Guide, little attention or content was allocated to the subject of enrichment until the current (8th) edition (NRC 2011). Although animal wellbeing, social environment, psychological well-being...

Environmental enrichment and the behavioural needs of macaques housed in large social groups

In this article, we address some of the issues surrounding the behavioural needs of captive animals and go on to elucidate some of the key aspects of the environmental enrichment strategy at Bioculture (Mauritius) (BCM) designed to balance safety, animal...

Effects of play caging on the behavior and enrichment use of singly-housed rhesus macaques

This study examined whether allowing 10 singly-housed adult male rhesus macaques (Macaca mulatta) 2-week access to a larger play cage would increase their species-typical behavior and decrease anxiety and abnormal behavior. The play cage consisted of four interconnected cages equipped...

Efficacy of 3 types of foraging enrichment for rhesus macaques (Macaca mulatta)

The 3 enrichment devices had different effects on individual expression of stereotypy: supertubes decreased it, shakers increased it, and puzzle balls led to a decrease followed by an increase. We present potential reasons for the changes in stereotypy and postulate...

Going back to nature: The benefits of wood enrichment

Environmental enrichment can be defined as altering the living environment of captive animals in order to provide them with opportunities to express more of their natural behavioral repertoire. The challenge of providing effective enrichment in laboratory species is to ensure...

Effect of marginal environmental and social enrichment during rearing on pigs’ reactions to novelty, conspecifics and handling

The rearing environment of farmed animals can affect their behaviour when handled, and therefore needs to be taken into account when selecting for traits such as docility. Therefore, 126 German Landrace and Pietrain × German Landrace pigs were reared in...

Using enrichment to improve welfare and reduce suffering

European Directive 2010/63/EU requires that accommodation and care are refined so as to minimize suffering, and that the lifetime experience of the animal is taken into account when assessing the actual severity of procedures. So, with respect to these requirements,...

The benefits of adding a little color to a monkey’s environment
