The impact of light, noise, cage cleaning and in-house transport on welfare and stress of laboratory rats
Contributor(s):: Castelhano-Carlos, M. J., Baumans, V.
Human interaction and physical environmental factors are part of the stimuli presented to laboratory animals everyday, influencing their behaviour and physiology and contributing to their welfare. Certain environmental conditions and routine procedures in the animal facility might induce stress...
Human-animal interactions and animal welfare in conventionally and pen-housed rats
Contributor(s):: Augustsson, H., Lindberg, L., Hoglund, A. U., Dahlborn, K.
The main aim of the present study was to explore the significance of large group/greater pen housing (PH) versus standard Makrolon caging (ST) in three behaviour tests related to human-animal interactions in the adult male laboratory rat. The rats' perception of human interaction was tested in...

Genetic analysis of reactivity to humans in Goettingen minipigs
Contributor(s):: Kohn, F., Sharifi, A. R., Simianer, H.
Goettingen minipigs are laboratory animals with an increasing demand over the last few years. At the moment, Goettingen minipigs are not selected for a low reactivity to humans and this trait is not included in the breeding programme. However, it is obvious that there is a need for genetically...
Behavioural effects of environmental enrichment for individually caged rabbits
Contributor(s):: Lidfors, L.
The behavioural effects of providing 60 male New Zealand laboratory rabbits with one of four objects in their individual cages as environmental enrichment were investigated. The rabbits were assigned to one of 5 treatments by a random procedure; hay in a water bottle, grass-cubes, two gnawing...
Understanding behaviour: the relevance of ethological approaches in laboratory animal science. (International Society for Applied Ethology Special Issue)
Contributor(s):: Olsson, I. A. S., Nevison, C. M., Patterson-Kane, E. G., Sherwin, C. M., Weerd, H. A. van de, Wurbel, H.
Applied ethology has traditionally focused on farm animal species, whereas there has been much less research directed at understanding the behaviour of laboratory animals in relation to their use as models in research. In this paper, we identify four areas in which ethological approaches could...
Influence of cage enrichment on aggressive behaviour and physiological parameters in male mice
Contributor(s):: Loo, P. L. P. van, Kruitwagen, C. L. J. J., Koolhaas, J. M., Weerd, H. A. van de, Zutphen, L. F. M. van, Baumans, V.
From welfare perspective group, housing of mice is preferred over individual housing. Group housing of male laboratory mice, however, often leads to problems due to excessive aggressive behaviour. In our search for management and housing modifications to decrease aggression in group-housed male...
Training rats to search and alert on contraband odors
Contributor(s):: Otto, J., Brown, M. F., Long, W., III
This paper describes a series of behavioral experiments that were conducted to test a new concept using rats to detect contraband odors, such as explosives, drugs, or prohibited foodstuffs. Under this concept, the trained alerting behaviour of rats is remotely monitored by humans and/or computers...
Rats show aversion to argon-induced hypoxia
Contributor(s):: Makowska, I. J., Niel, L., Kirkden, R. D., Weary, D. M.
Laboratory rats and mice are commonly killed using carbon dioxide gas. However, recent studies have shown that rodents find this gas aversive. Argon is a tasteless and odourless gas that causes hypoxia by displacing air. The aim of the present study was to use approach-avoidance testing to...
Effects of a gentling programme on the behaviour of laboratory rats towards humans
Contributor(s):: Maurer, B. M., Doring, D., Scheipl, F., Kuchenhoff, H., Erhard, M. H.
The present study investigated the effects of a gentling programme on the later behaviour of laboratory rats towards humans. For that purpose, 24 female Wistar rats were purchased from a laboratory animal breeding facility at the age of 21 days and allocated, genetically balanced, to an...
Development of stereotypies and polydipsia in wild caught bank voles ( Clethrionomys glareolus ) and their laboratory-bred offspring. Is polydipsia a symptom of diabetes mellitus?
Contributor(s):: Schoenecker, B., Heller, K. E., Freimanis, T.
The development of stereotypies and polydipsia was studied in wild caught bank voles (P: n=92) and their laboratory-bred offspring (F1: n=248). All animals were kept isolated in barren cages in the laboratory. In the P generation, no individuals developed stereotypies, but 22% developed...
