A cage without a view increases stress and impairs cognitive performance in rats
Contributor(s):: Harris, A. P., D'Eath, R. B., Healy, S. D.
Single housing is believed to be chronically stressful and to have a negative impact on welfare and cognition in rats (Rattus norvegicus). However, single housing does not consistently evoke stress-like responses nor does it consistently impair cognitive performance. In an experiment in which all...
A comparative approach to the study of Keeper-Animal Relationships in the zoo. (Special Issue: Zoo animal welfare.)
Contributor(s):: Carlstead, K.
Research on intensively farmed animals over the past 25 years has shown that human-animal interactions, by affecting the animal's fear of humans, can markedly limit the productivity and welfare of farm animals. This article begins to explore some of the factors that need to be considered to...
A comparison of inferential analysis methods for multilevel studies: Implications for drawing conclusions in animal welfare science
Contributor(s):: Stevens, Kara N., Asher, Lucy, Griffin, Kym, Friel, Mary, O'Connell, Niamh, Collins, Lisa M.
Investigations comparing the behaviour and welfare of animals in different environments have led to mixed and often conflicting results. These could arise from genuine differences in welfare, poor validity of indicators, low statistical power, publication bias, or inappropriate statistical...
A critical review of the evidence for the equivalence of canine and human compulsions

A flooring comparison: the impact of rubber mats on the health, behavior, and welfare of group-housed sows at breeding
Contributor(s):: Elmore, M. R. P., Garner, J. P., Johnson, A. K., Richert, B. T., Pajor, E. A.
Comfortable flooring may impact many aspects of an animal's welfare, including lying behavior, an animal's ability to change postures, and incidence of lameness and lesions. Therefore, we hypothesized that the addition of rubber mats to stalls of group pens would improve sow health, comfort and...
A lifesaving model: teaching advanced procedures on shelter animals in a tertiary care facility

A meta-analysis of the combined effect of housing and environmental enrichment characteristics on the behaviour and performance of pigs
Contributor(s):: Averos, X., Brossard, L., Dourmad, J. Y., Greef, K. H. de, Edge, H. L., Edwards, S. A., Meunier-Salaun, M. C.
To quantify the combined effect of housing conditions and environmental enrichment on the behaviour and performance of pigs, a meta-analysis was performed using information from 45 experiments in 42 published manuscripts. Multiple regression models were applied to evaluate the effects of space...
A model of stockperson-animal interactions and their implications for livestock
Contributor(s):: Hemsworth, P. H., Coleman, G. J.
This chapter presents a model of human-animal interactions in livestock production based on the factors involved in the relationship between stockperson and farm animal variables, including the influence of stockperson attitudes on his/her behaviour and of stockperson behaviour on animal...
A model to predict the likelihood of cliff swallow nesting on highway structures in northern California

A modeling approach for estimating seasonal dietary preferences of goats in a Mediterranean Quercus frainetto-Juniperus oxycedrus woodland
Contributor(s):: Manousidis, T., Malesios, C., Kyriazopoulos, A. P., Parissi, Z. M., Abraham, E. M., Abas, Z.
Goats are characterized as selective feeders due to their specific feeding behavior, thus the study of their seasonal preferences in a Mediterranean oak-juniper ecosystem is of great interest. The current research was conducted in an open oak forest in Megalo Dereio region, northeastern Greece...
A multiple indicators multiple cause (MIMIC) model of respiratory health and household factors in Chinese children: The Seven Northeastern Cities (SNEC) Study

A network model of H5N1 avian influenza transmission dynamics in domestic cats
Contributor(s):: Ayyalasomayajula, S., DeLaurentis, D. A., Moore, G. E., Glickman, L. T.
Naturally occurring cases of influenza in cats owing to the H5N1 strain have been reported in several countries. A cat reservoir of H5N1 in the United States could provide an environment for zoonotic disease spread to humans. This scenario was the impetus to develop a model to study potential...
A novel flexible method to split feeding behaviour into bouts
Contributor(s):: Howie, J. A., Tolkamp, B. J., Avendano, S., Kyriazakis, I.
Before meal patterns can be analysed properly, a biologically relevant meal criterion must be determined in order to group short-term feeding behaviour into meals. Existing methodologies are based on modelling of the frequency distributions of intervals between feeding events but these methods...
A quantitative safety assessment model for transgenic protein products produced in agricultural crops
Contributor(s):: Howard, J. A., Donnelly, K. C.
Transgenic plants are now being used to develop pharmaceutical and industrial products in addition to their use in crop improvement. Using confinement requirements, these transgenic plants are grown and processed under conditions that prevent intermixing with commodity crops. Regulatory agencies...
A randomized cross-over exploratory study of the effect of visiting therapy dogs on college student stress before final exams
Contributor(s):: Barker, S. B., Barker, R. T., McCain, N. L., Schubert, C. M.
This exploratory study investigated the effect of visiting therapy dogs on college-student perceived and physiological stress the week prior to final exams. Students ( n=78) were randomly assigned to order of a therapy-dog intervention and attention-control condition, each 15 minutes long....

A refinement and validation of the Monash Canine Personality Questionnaire (MCPQ)
Contributor(s):: Ley, J. M., Bennett, P. C., Coleman, G. J.
The investigation of canine personality has failed to find strong agreement between studies as to its structure. The area has been hampered by a reliance on human personality models and by a tendency to limit the types of dogs used as subjects. These problems were recently addressed during the...
