The quantification of behaviours linked to anxiety or stress provides a powerful means to address applied questions related to the well-being of captive animals. This study explored correlates of two such behaviours: self-directed (SDB) and...

The welfare of zoo animals depends on a combination of physical, social, dietary and other ecological characteristics of the captive setting. We analysed the influence of the transfer of an adult couple of hamadryas baboons...

Each chapter follows a consistent pattern describing the behavioral characteristics of the species featured. Reference is made to the natural state before domestication, leading us through the various changes to the present, demonstrating along the...

Improving the home cages of laboratory mice by environmental enrichment has been widely used to reduce cage stereotypies and anxiety-related behaviour in behavioural tests. However, enrichment studies differ substantially in type, complexity and variation of...

Tosa, N., Yoshimatsu, K., Arikawa, J. 2011. Effect of environmental enrichment after the occurrence of wet bedding created by mice and abnormal fur in mice. American Association for Laboratory Animal Sc

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...

Van de Perre, V., Driessen, B., Van Thielen, J. et al. 2011. Comparison of pig behaviour when given a sequence of enrichment objects or a chain continuously. Animal Welfare 20(4), 641-649.

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...

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...

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...

A behavioral data collection system is described to monitor compatibility of rhesus macaque pairs.

Bechard, A., Meagher, R., Mason, G. 2011. Environmental enrichment reduces the likelihood of alopecia in adult C57BL/6J mice. JAALAS 50(2), 71-74.

Barbering (incessant grooming) is an abnormal behavior causing alopecia and commonly affects various strains of laboratory mice, including C57BL/6J. Barbering-induced alopecia is a potential symptom of brain impairment and can indicate a stressful environment. We...
