The four Cs of psychological wellbeing: Lessons from three decades of computer-based environmental enrichment

Three decades ago, the Animal Welfare Act was amended to require researchers to provide environments that promoted the psychological, as well as the physical, wellbeing of nonhuman primates maintained for research purposes. We developed a computer-task paradigm with the goal...

Species specific differences in short-term behavioral reaction of voles to cage elements removal

The welfare of animals used in scientific experiments should be one of the most important things to take care of. Many kinds of research show that the enriching elements can help animals to fulfil their natural behaviour. However, those studies...

Common aquarium plants as an enrichment strategy in zebrafish

An increasing number of laboratories utilize zebrafish as this species is now represented in practically every subfield of biology research. Environmental enrichment has been shown to improve welfare and health of a large number of species of animals studied in...

Minimising aggression in CD-1 and CD-1 background male mice with different enrichment types

Cage-mate aggression is a well-known problem that is more prevalent in certain strains of mice and is one of the most common reasons for single housing, increased stress levels, premature death and euthanasia. Numerous methods can be implemented to ameliorate...

Are mirrors aversive or rewarding for mice? Insights from the mirror preference test

Research investigating the effects of mirror exposure in mice found that the presence of mirrors has similar effects to the presence of cage mates. Restraint in a small holder induces hyperthermia (stress-induce hyperthermia: SIH) in mice but a restrained mouse...

The effects of various enrichment methods on the engagement nd inter-group behaviour of captive chacma baboons

The goal of this study was to answer two research questions: (1) how important is it to rotate enrichment types to maintain high levels of engagement in individually-housed adult chacma baboons? and (2) which methods of enrichment prompt the highest...

Managing long-term wellness in captive sea turtles

Circumstances surrounding advances in stranding response and veterinary care have created a growing need for the long-term housing of captive sea turtles. However, the difficulty in recreating natural conditions in captive settings places a responsibility on caregivers to offset wild-type...

Farm animal enrichments improve the welfare of layer chicks and pullets: A comprehensive review

Currently, cage housing is regarded as a global mainstream production system for laying hens. However, limited living space and confinement of birds in cages cause welfare and health problems, such as feather pecking, osteoporosis, obesity, and premature aging. Many studies...

Use of qualitative behavioural assessment to investigate affective states of housed dairy cows under different environmental conditions

In addition to the reduction of suboptimal welfare, there is now a need to provide farmed animals with positive opportunities to provide confidence that they have experienced a life worth living. Diversification of the environment through environmental enrichment strategies is...

Effects of stocking rate and environmental enrichment on the ontogeny of pecking behavior of laying hen pullets confined in aviary compartments during the first 4 weeks of life

The objective of this study was to describe the ontogeny of the severe feather pecking (SFP), gentle feather pecking (GFP), aggressive pecking (AP), and enrichment pecking (EP) of non-beak-trimmed Lohmann Brown (LB)-pullets during the first 4 weeks of life (observation...
