  1. In-homecage blood collection from conscious stumptailed macaques

    Contributor(s):: Reinhardt, V., Cowley, D.

  2. Intra-abdominal transmitter implantation in mice: effects on behaviour and body weight

    Contributor(s):: Baumans, V., Bouwknecht, J. A., Boere, H., Kramer, K., Lith, H. A. van, Weerd, H. A. van de, Herck, H. van

  3. Laboratory animal, pet animal, farm animal, wild animal: which gets the best deal?

    Contributor(s):: Wolfensohn, S., Honess, P.

    A veterinary surgeon wishing to practice in the UK promises, on admission to the Royal College of Veterinary Surgeons, that their "constant endeavour will be to ensure the welfare of the animals committed to [their] care" (RCVS 2006 Guide to Professional Conduct). Yet a constant dilemma is that...

  4. Lower-row caging in a two-tiered housing system does not affect the behaviour of young, singly housed rhesus macaques

    Contributor(s):: Schapiro, S. J., Bloomsmith, M.

    It has been suggested that housing of laboratory primates in two-tiered racks adversely affects the psychological well-being of those primates housed on the lower row. Excessive darkness and its consequences are among the factors suggested to account for the supposed diminished well-being of...

  5. m Stereotypic behaviour in wild caught and laboratory bred bank voles ( Clethrionomys glareolus )

    Contributor(s):: Cooper, J. J., Nicol, C. J.

  6. Mealworm dispensers as environmental enrichment for captive Rodrigues fruit bats ( Pteropus rodricensis )

    Contributor(s):: O'Connor, K. I.

    This study is an assessment of the use of mealworm dispensers as environmental enrichment devices for Rodrigues fruit bats (Pteropus rodricensis). Captive animals frequently receive easily consumed food at set times and locations, which often minimizes the time they spend searching for and...

  7. Measurement of aversion to determine humane methods of anaesthesia and euthanasia

    Contributor(s):: Leach, M. C., Bowell, V. A., Allan, T. F., Morton, D. B.

    The distress experienced by animals during the induction of unconsciousness remains one of the most important and yet overlooked aspects of effective methods of anaesthesia and euthanasia. Here, we show that considerable differences exist in the aversive responses elicited by 12 common methods of...

  8. Meta-analysis - a systematic and quantitative review of animal experiments to maximise the information derived

    Contributor(s):: Phillips, C. J. C.

    Meta-analysis provides a tool to statistically aggregate data from existing randomised controlled animal experiments. The results can then be summarised across a range of conditions and an increased pool of experimental data can be subjected to statistical analysis. New information can be...

  9. Modifying the behaviour of singly caged baboons: evaluating the effectiveness of four enrichment techniques

    Contributor(s):: Bourgeois, S. R., Brent, L.

    Techniques to reduce or prevent behavioural disturbances in singly caged primates vary in form and effectiveness, with some behaviours being exceptionally resistant to treatment. Seven singly caged adolescent male olive hybrid baboons (Papio hamadryas anubis) were selected for behavioural...

  10. Modulation of aggression in male mice: influence of cage cleaning regime and scent marks

    Contributor(s):: Loo, P. L. P. van, Kruitwagen, C. L. J. J., Zutphen, L. F. M. van, Koolhaas, J. M., Baumans, V.

    Group housing of male laboratory mice often leads to welfare problems due to aggressive behaviour. From a welfare perspective, individual housing is not a preferred solution to these problems - and so other ways of reducing aggression between male mice were sought. Aggression peaks after...

  11. Nest-building behaviour in male rats from three inbred strains: BN/HsdCpb, BDIX/OrIIco and LEW/Mol

    Contributor(s):: Jegstrup, I. M., Vestergaard, R., Vach, W., Ritskes-Hoitinga, M.

    Three inbred strains of male laboratory rat (BN/HsdCpb, BDIX/OrIIco and LEW/Mol) were provided with nest boxes and nest materials, and were observed for nest-building activity. After 7 days, each cage and nest box was examined. Each nest was weighed and scored for complexity, and returned to the...

  12. Painful dilemmas: the ethics of animal-based pain research

    Contributor(s):: Magalhaes-Sant'Ana, M., Sandoe, P., Olsson, I. A. S.

    While it has the potential to deliver important human benefits, animal-based pain research raises ethical questions, because it involves inducing pain in sentient beings. Ethical decision-making, connected with this variety of research, requires informed harm-benefit analysis, and the aim of this...

  13. Part-time fostering by a pair of black and white ruffed lemurs ( Varecia variegata variegata )

    Contributor(s):: Kerridge, F. J.

  14. Preferences for nest boxes as environmental enrichment for laboratory mice

    Contributor(s):: Weerd, H. A. van de, Loo, P. L. P. van, Zutphen, L. F. M. van, Koolhaas, J. M., Baumans, V.

  15. Preferences of laboratory mice for characteristics of soiling sites

    Contributor(s):: Sherwin, C. M.

    When designing cages to maximize welfare, both the physical and psychological needs of the animals for which the cage is intended should be considered. Many laboratory species show non-random defecation patterns and therefore might possess a psychological need for soiling sites with preferred...

  16. Rats demand social contact

    Contributor(s):: Patterson-Kane, E. G., Hunt, M., Harper, D.

  17. Refinement of gerbil housing and husbandry in the laboratory

    Contributor(s):: Waiblinger, E., Konig, B.

    Mongolian gerbils (Meriones unguiculatus) are a widely used model species in parasitology and epilepsy research. Under standard laboratory housing conditions gerbils develop stereotypic digging, a behavioural abnormality, which is caused by the lack of a burrow in the laboratory cage. Here, we...

  18. Repetitive backflipping behaviour in captive roof rats ( Rattus rattus ) and the effects of cage enrichment

    Contributor(s):: Callard, M. D., Bursten, S. N., Price, E. O.

    Repetitive 'stereotyped' behaviours are often performed by both wild and domestic rodents in small laboratory cages. In this study, a behaviour resembling a backwards somersault or backflip is described and quantified in captive roof rats (ship or black rats, Rattus rattus). Videotapes of...

  19. Restraint methods of laboratory non-human primates: a critical review

    Contributor(s):: Reinhardt, V., Liss, C., Stevens, C.

    This paper contains 34 topics covering the assessment, ethics, policy and care of domestic, zoo, laboratory and wild animals.
