  1. Social context and other factors influence the behavioural expression of pain by lambs

    Contributor(s):: Guesgen, M. J., Beausoleil, N. J., Minot, E. O., Stewart, M., Stafford, K. J.

    There is evidence that the presence of a conspecific can alter the experience of pain in humans and other animals. This 'social buffering' may be mediated by factors such as relatedness and familiarity. This study investigates whether and how the social context affects the behavioural response of...

  2. Lateralization of agonistic and vigilance responses in Przewalski horses ( Equus przewalskii)

    Contributor(s):: Austin, N. P., Rogers, L. J.

    Eye and limb preferences were scored in the closest undomesticated relative of Equus caballus using the same methods as used previously to study laterality in feral horses. Observations were made of 33 Przewalski horses ( Equus ferus przewalskii) (male N=20, female N=13) living under natural...

  3. Responses of shelter and pet dogs to an unknown human

    Contributor(s):: Barrera, G., Jakovcevic, A., Elgier, A. M., Mustaca, A., Bentosela, M.

    Canine shelters frequently have inadequate living conditions that affect the behavior of dogs. This study compared fear-appeasement and sociability reactions in shelter and pet dogs when they are confronted by an unfamiliar experimenter. Results indicated that shelter dogs used for this study...

  4. An ethological approach to housing requirements of golden hamsters, Mongolian gerbils and fat sand rats in the laboratory - a review

    Contributor(s):: Sorensen, D. B., Krohn, T., Hansen, H. N., Ottesen, J. L., Hansen, A. K.

    When housing hamsters and gerbils little has been done to identify the preferences of these species. The solitary nature of fat sand rats and hamsters is often discordant with housing practices in animal laboratories. This article provides a comparison of the behaviour of wild-living animals with...

  5. Emotional reactivity of Japanese quail chicks with high or low social motivation reared under unstable social conditions

    Contributor(s):: Schweitzer, C., Arnould, C.

    Repeated encounters with unfamiliar conspecifics in large groups of domestic birds create a potentially stressful social environment which can affect the birds' emotional reactivity and consequently their welfare. As social relationships between young quail are particularly influenced by their...

  6. Individualistic herds: individual variation in herbivore foraging behavior and application to rangeland management

    Contributor(s):: Searle, K. R., Hunt, L. P., Gordon, I. J.

    Rangeland systems cover vast areas of the earth's surface containing great diversity of life, and contribute to the livelihoods and welfare of millions of people. The management of rangeland systems for ecological and commercial outcomes is driven by a need to understand how grazing animals...

  7. Selection against aggressiveness in pigs at re-grouping: practical application and implications for long-term behavioural patterns

    Contributor(s):: Turner, S. P., D'Eath, R. B., Roehe, R., Lawrence, A. B.

    The routine mixing of pigs causes aggression that cannot be greatly reduced by low-cost environmental changes. The variability and heritability of aggressiveness are discussed and both appear adequate to make selection against aggressiveness worthwhile in grower-stage pigs. Selection would...

  8. The influence of urbanization on the behaviour of dogs in the Czech Republic

    Contributor(s):: Baranyiova, E., Holub, A., Tyrlik, M., Janackova, B., Ernstova, M.

    The aim of this study was to evaluate the influence of urbanization in the Czech Republic on the coexistence of domesticated dogs and their owners. The data from a questionnaire (distributed to dog owners) were divided into rural (R, n=164) and urban (U, n=132). The former group comprised of dogs...
