  1. Behavioral assessment of intermittent wheel running and individual housing in mice in the laboratory

    Contributor(s):: Pham, T. M., Brene, S., Baumans, V.

    Physical cage enrichment - exercise devices for rodents in the laboratory - often includes running wheels. This study compared responses of mice in enriched physical and social conditions and in standard social conditions to wheel running, individual housing, and open-field test. The study...

  2. Combination therapy reduces self-injurious behavior in a chimpanzee ( Pan troglodytes troglodytes ): a case report

    Contributor(s):: Bourgeois, S. R., Vazquez, M., Brasky, K.

    Self-injurious behavior (SIB) remains a severe and intractable abnormal behavior for nonhuman primates in diverse settings and is a significant concern for veterinarians and behavioral scientists. To date, no single pharmacological, behavioral, social, or environmental intervention method has...

  3. Compassion for animals in the laboratory: impairment or refinement of research methodology?

    Contributor(s):: Reinhardt, V.

    There are now signs in the United States as well as in Europe that the importance of a positive human-nonhuman animal relationship in research laboratories is appreciated more seriously. In addition to knowledge and skills, primary attributes of animal research personnel must be feelings of...

  4. Deprivation and Enrichment in Laboratory Animal Environments

    Contributor(s):: Burghardt, Gordon M.

    Comments on enrichment issues associated in laboratory animal environments in the United States. Roles of researchers, administrators and veterinarians in the implementation of guidelines and regulations for improving welfare of research animals; Publication of articles on animal welfare as tool...

  5. Distribution of nonhuman animal versus nonanimal research funding at four U.S. Institutions in fiscal year 2000

    Contributor(s):: Bogle, R., Greek, R.

    Much controversy exists concerning the use of nonhuman animals in biomedical research. Textbooks, articles, and journals are dedicated to studying animal models, studying alternatives, and debating various aspects of the issue. Surprisingly however, very little information exists on how many...

  6. Do male mice prefer or avoid each other's company? Influence of hierarchy, kinship, and familiarity

    Contributor(s):: Loo, P. L. P. van, Groot, A. C. de, Zutphen, B. F. M. van, Baumans, V.

    In the laboratory, individual housing of male mice who otherwise show aggression is common practice. Because mice are a social species, the question arises whether this procedure is right from the animals' point of view. This study tested the preference of subordinate animals for their dominant...

  7. ECVAM Workshop on Alternatives to the Use of Animals in Higher Education

    Contributor(s):: Balcombe, Jonathan

    Details the European Centre for the Validation of Alternative Methods Workshop on alternatives to the use of animals in higher education in Crete, Greece. List of participants; Presentation of a wide range of viewpoints; Need for greater publicity for the availability and efficacy of...

  8. Effects of environmental enrichment for mice: variation in experimental results

    Contributor(s):: Weerd, H. A. van de, Aarsen, E. L., Mulder, A., Kruitwagen, C. L. J. J., Hendriksen, C. F. M., Baumans, V.

    This study focused on the effects of different enriched environments for mice in a number of behavioural and physiological parameters in 2 routine laboratory testing procedures: potency testing for tetanus vaccine and stress-induced hyperthermia. The variability in the results was studied by...

  9. Environmental enrichment alters the behavioral profile of ratsnakes ( Elaphe )

    Contributor(s):: Almli, L. M., Burghardt, G. M.

    This study investigated the effects of environmentally enriched and standard laboratory housing conditions on behavioral performance in 16 subadult ratsnakes (Elaphe obsoleta) using a split-clutch design. In a problem-solving task, snakes housed in enriched environments (EC) exhibited shorter...

  10. Genetic engineering and other factors that might affect human-animal interactions in the research setting

    Contributor(s):: Comber, J., Griffin, G.

    Evidence exists, particularly in the welfare literature of nonhuman animals on the farm, that the interaction between nonhuman animals and the personnel who care for them can have a strong effect on the animals' behavior, productivity, and welfare. Among species commonly used for biomedical...

  11. Genetically modified laboratory animals - what welfare problems do they face?

    Contributor(s):: Buehr, M., Hjorth, P. J., Hansen, A. K., Sandoe, P.

    In this article, we respond to public concern expressed about the welfare of genetically modified (GM) non-human animals. As a contribution to the debate on this subject, we attempt in this article to determine in what situations the practice of genetic modification in rodents may generate...

  12. Global harmonization of pain and distress classification systems: current analysis and opportunity for change

    Contributor(s):: Purves, K. E.

    When humans suffer pain or distress, they are generally able to describe their experience to others, including doctors. Medical professionals are also able to convey the likelihood of pain and distress to humans who are voluntarily participating in clinical research trials. The same is not true...

  13. Legal space requirement stipulations for animals in the laboratory: are they adequate?

    Contributor(s):: Reinhardt, V., Reinhardt, A.

    Animals in the laboratory need the legally required "empty space" to meet their basic spatial requirements for postural adjustment, but they also deserve functional-structured-space for species-typical locomotor behavior and dynamic interaction with their physical environment. Primary enclosures...

  14. Noise exposure, music, and animals in the laboratory: a commentary based on Laboratory Animal Refinement and Enrichment Forum (LAREF) discussions

    Contributor(s):: Patterson-Kane, E. G., Farnworth, M. J.

    The effects of noise, in general, and music, in particular, on the behavior and welfare of animals in the laboratory deserve a great deal of empirical study. However, many laboratories must develop their current practices on the basis of sparse and conflicting data. With this commentary we seek...

  15. Noncompliance with Public Health Service (PHS) policy on humane care and use of laboratory animals: an exploratory analysis

    Contributor(s):: Gomez, L. M., Conlee, K. M., Stephens, M. L.

    The National Institutes of Health (NIH) is a major biomedical research-funding body in the United States. Approximately 40% of NIH-funded research involves experimentation on nonhuman animals (Monastersky, 200811. Monastersky, R. 2008, April 18. Protesters fail to slow animal research. The...

  16. Outcome of cats adopted from a biomedical research program

    Contributor(s):: DiGangi, B. A., Crawford, P. C., Levy, J. K.
