Environmentally enriching American mink ( Neovison vison) increases lymphoid organ weight and skeletal symmetry, and reveals differences between two sub-types of stereotypic behaviour
Contributor(s):: Diez-Leon, M., Bursian, S., Galicia, D., Napolitano, A., Palme, R., Mason, G.
Enrichment studies for wild carnivores (e.g., in zoos) are often short-term, use enrichments of unknown motivational significance, and focus on glucocorticoids and stereotypic behaviour (SB), ignoring other stress-relevant variables. Our study assessed the broad behavioural and physiological...
The use of positive reinforcement in training zebra sharks ( Stegostoma fasciatum)
Contributor(s):: Marranzino, A.
Positive reinforcement training (PRT) was used on 4 adult zebra sharks, Stegostoma fasciatum, housed at the Downtown Aquarium, Denver, to determine the ability of zebra sharks to become desensitized to various stimuli associated with veterinary procedures. One male and 3 female sharks were...
Review of human-animal interactions and their impact on animal productivity and welfare
Contributor(s):: Idrus, Zulkifli
Humans and animals are in regular and at times close contact in modern intensive farming systems. The quality of human-animal interactions can have a profound impact on the productivity and welfare of farm animals. Interactions by humans may be neutral, positive or negative in nature. Regular...
Genetic and dietary effects on chicken heterophil function and immune response to Salmonella enteritidis
Contributor(s):: Sarah Beth Redmond, Susan J. Lamont (adviser)
The function of the chicken innate immune system against pathogens is affected by genetic background and immune modulating diet. Heterophils from broiler, Leghorn, and Fayoumi birds showed differential expression of immune genes when stimulated with Salmonella enteritidis (SE) bacteria, a...
Reduction in mucosal barrier markers with soy protein diet but not Lactobacillus rhamnosus GG in DSS-treated mice
Contributor(s):: Huanyi Jiang, Ruth S. MacDonald (adviser)
Inflammatory bowel disease (IBD) is a common ailment affecting people of all ages. Even though the pathogenesis of IBD has not been fully elucidated, there is evidence that it involves interactions between genetic susceptibility, aberrant activation of the immune system, and the environment....
Whole transcriptome response of chicken spleen and peripheral blood leukocytes to avian pathogenic Escherichia coli
Contributor(s):: Erin Elizabeth Sandford, Susan J. Lamont (adviser)
A greater understanding of the immune response after infection can form the necessary foundation of knowledge needed to enhance immunity through genetic selection. Whole genome microarrays allow for comprehensive analysis of the transcriptome. The transcriptomic responses of spleen and peripheral...
Main causes of poor welfare in intensively reared dairy cows. (Special Issue: Criteria and methods for the assessment of animal welfare.)
Contributor(s):: Abeni, F., Bertoni, G.
The aim of this review is to summarise the main causes of poor welfare in intensively reared dairy cows. Intensive farming systems are considered, both from a structural and a managerial point of view, for their constraints that may limit animal welfare: possible physical activity; acceptable...

The welfare of gestating sows in conventional stalls and large groups on deep litter
Contributor(s):: Karlen, G. A. M., Hemsworth, P. H., Gonyou, H. W., Fabrega, E., Strom, A. D., Smits, R. J.
Confinement of breeding sows and gilts is a controversial welfare issue in livestock production and there is worldwide interest in finding alternative housing systems for gestating pigs. This study measured aspects of the welfare of gestating sows housed in either large groups on deep litter...

Assessment of welfare from physiological and behavioural responses of New Zealand dairy cows exposed to cold and wet conditions
Contributor(s):: Webster, J. R., Stewart, M., Rogers, A. R., Verkerk, G. A.
There is a need to assess the welfare of dairy cows that live outdoors under cold and wet conditions. This study combined a number of techniques to measure stress and make an assessment of welfare in this situation. Two groups often non-pregnant, non-lactating Holstein Friesian cows were exposed...
Quality of life means welfare: how is it related to other concepts and assessed?
Contributor(s):: Broom, D. M.
Our view of which individuals should be the subjects of our moral actions is expanding to include more people and more species. Animal welfare is the subject of rapidly increasing concern in most countries in the world, and this concern is resulting in changes in the ways in which animal users...
