Shelter choice by Syrian hamsters (Mesocricetus auratus) in the laboratory

The preference of Syrian hamsters (Mesocricetus auratus) for different in-cage shelters was tested. First, 15 males and 15 females were made to choose between a cage with a shelter and one without. Different shelters were tested consecutively: short (10-cm) or...

Comparison of pig behaviour when given a sequence of enrichment objects or a chain continuously

Tail biting is a major problem in modern pig (Sus scrofa) production and results in a reduction of animal welfare and productive performance. Biting behaviour has been shown to be decreased by the use of enrichment objects. In this study,...

Effect of environmental enrichment after the occurrence of wet bedding created by mice and abnormal fur in mice

In management of laboratory animals, wet bedding created by mice and abnormal fur in mice cause problems on housing, leading to negative effects both on the wellbeing of mice and on the validity of experimental results. Most studies have investigated...

Environmental enrichment program in transgenic mouse breeding colonies

Results of studies on the benefits of environmental enrichment in group-housed mice and breeding colonies are often inconsistent and conflicting. After observing a significant drop in some of the genetically engineered mice (GEM) breeding colonies during a major construction project...

Common Marmoset Care [Online resource]

The three main divisions of 'marmosetcare.com' aim respectively to promote: an understanding of the range of behaviour in this species, placing this behaviour in the context of its natural habitat and promoting good welfare in captive environments. Topics covered in...

Integrating aromatherapy into the nonhuman primate enrichment program

Aromatherapy has been used as a method for reducing anxiety and increasing relaxation throughout history. The Chinese were credited with using aromatic plants for wellbeing. They would burn incense to help create balance and harmony. The Egyptians used distillation and...

The effect of housing and environmental enrichment on stereotyped behavior of adult vervet monkeys (Chlorocebus aethiops)

Little information is available on the response of vervet monkeys to different housing conditions or on the suitability of enrichment devices or methods for vervet monkeys. In this study, the authors evaluated the occurrence of stereotyped behavior in adult vervet...

Evaluating paint rollers as an intervention for alopecia in monkeys in the laboratory (Macaca nemestrina)

Adult female macaques (Macaca nemestrina) in the laboratory with alopecia from known or suspected overgrooming were subjects in a study evaluating effectiveness of a grooming device. The intervention evaluated was a paint roller on a metal bar hung on the...

Improving the welfare of captive macaques (Macaca sp

This review evaluates the use of water as a tool for enriching the environments of macaques (Macaca sp.) in captivity. Many macaque species are known to swim and forage in water in the wild, and in-situ reports suggest that access...

An assessment of gum-based environmental enrichment for captive gummivorous primates

In the wild, many primates consume gums exuded from trees, and many species are gum specialists. In spite of this, few data exist concerning gum feeding in captivity. Using a web-based survey of 46 zoos in 12 countries, we evaluated...
