  1. Keeping circus elephants temporarily in paddocks - the effects on their behaviour

    Contributor(s):: Schmid, J.

  2. Light, vision and the welfare of poultry

    Contributor(s):: Prescott, N. B., Wathes, C. M., Jarvis, J. R.

    The visual system of domestic poultry evolved in natural light environments, which differ in many respects from the artificial light provided in poultry houses. Current lighting systems are designed mainly around human vision and poultry production, ignoring the requirements of poultry vision and...

  3. Long-term consistency of selected animal-related welfare parameters in dairy farms

    Contributor(s):: Winckler, C., Brinkmann, J., Glatz, J.

    It was the purpose of this study to assess the consistency of selected animal-based welfare parameters for dairy cattle throughout a one-year period. Eight cubicle-housed dairy herds were visited five times, at two-monthly intervals. At each visit, lameness, injuries to the carpal and tarsal...

  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. Maternal response to mother-offspring separation in the chimpanzee ( Pan troglodytes )

    Contributor(s):: Bloomsmith, M. A., Tarou, L. R., Lambeth, S. P., Haberstroh, M. D.

    For management and/or research purposes, chimpanzee mothers and their offspring are often physically separated from one another at an earlier age than they would be in the wild. Studies of the behavioural and physiological effects of mother-infant separation on infant behaviour have been...

  6. Methodological aspects for the assessment of social behaviour and avoidance distance on dairy farms

    Contributor(s):: Mulleder, C., Troxler, J., Waiblinger, S.

    Some aspects of on-farm assessment of social behaviour and avoidance distance were investigated on 20 Austrian dairy farms. The avoidance distance of at least 75% of cows was assessed. Social behaviour of the cows was observed for one hour and the number of animals standing was recorded every 10...

  7. 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...

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

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

  9. Rats demand social contact

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

  10. Relation between parity and feed intake, fear of humans and social behaviour in non-lactating sows group-housed under various on-farm conditions

    Contributor(s):: Kongsted, A. G., Hermansen, J. E., Kristensen, T.

    The number of group-housed, non-lactating sows is increasing rapidly in Europe. However, systematic information of the between-sow variation in animal welfare related factors under various on-farm conditions is lacking. Indicators of feed intake, fear of humans and social behaviour in...

  11. Social behaviour and injuries of horned cows in loose housing systems

    Contributor(s):: Menke, C., Waiblinger, S., Folsch, D. W., Wiepkema, P. R.

    The relationship between social behaviour and skin injuries (caused by horns) of loose housed horned cows was investigated on 35 dairy farms (mean herd-size, 34.54, range, 8-80). While the frequencies of 2 agonistic behaviour elements (push and chase away) were positively correlated with the...

  12. Social behaviour of collared peccaries ( Pecari tajacu ) under three space allowances

    Contributor(s):: Nogueira, S. S. da C., Silva, M. G., Dias, C. T. dos S., Pompeia, S., Cetra, M., Nogueira Filho, S. L. G.

    Captive breeding of peccaries is on the increase in neotropical countries. Few studies, however, have reported behavioural responses of wild animals under farmed conditions. Therefore, the aim of this study was to evaluate the effects of space allowance on the occurrence of social behaviour...

  13. Social roles in cattle: a plea for interchange of ideas between primatologists and applied ethologists

    Contributor(s):: Manteca, X., Deag, J. M.

  14. Socialization and stress in cats ( Felis silvestris catus ) housed singly and in groups in animal shelters

    Contributor(s):: Kessler, M. R., Turner, D. C.

    This study investigated whether the socialization of the cat towards conspecifics and people influences adaptation to single- and group-housing conditions. Socialization towards conspecifics and people was determined in 169 rescued cats using 2 behavioural tests and a socialization questionnaire...

  15. Stability of breeding and non-breeding groups of golden-headed lion tamarins ( Leontopithecus chrysomelas )

    Contributor(s):: Vleeschouwer, K. de, Leus, K., Elsacker, L. van

    In Callitrichid primates, offspring remain in their natal group beyond the age of sexual maturity, increasing the group's inclusive fitness by cooperatively rearing their siblings. Contraception of the dominant female in these groups may alter the associated costs and benefits of this cooperative...

  16. The effect of an audience on the gakel-call and other frustration behaviours in the laying hen ( Gallus gallus domesticus )

    Contributor(s):: Zimmerman, P. H., Lundberg, A., Keeling, L. J., Koene, P.

    When thwarted in a behaviour, laying hens show an increase in stereotyped pacing, displacement preening and a specific vocalization known as the gakel-call. How these behaviours, which might serve as indicators of welfare, are influenced by social factors is not yet known. In this study, the...

  17. The effect of contact with conspecifics and humans on calves' behaviour and stress responses

    Contributor(s):: Raussi, S., Lensink, B. J., Boissy, A., Pyykkonen, M., Veissier, I.

    In this study, we analysed the effects of social and human contact on calves' behaviour and stress responses. We also measured the effect of this contact on calves' reactions to novel conspecifics and novel humans. Sixty-four calves were housed either alone or in pairs and received either minimal...

  18. The effects of rearing conditions on grooming and play behaviour in captive chimpanzees

    Contributor(s):: Martin, J. E.

    The effects of maternal and peer separation during infancy and juvenescence on adolescent and adult chimpanzee behaviour were studied. The aim was to provide an insight into the social development of the species and to investigate human influence on this process. Forty-three adolescent and adult...

  19. The health, haematology and blood biochemistry of free-ranging farm cats in relation to social status

    Contributor(s):: Macdonald, D. W., Yamaguchi, N., Passanisi, W. C.

    A profile of the general health, haematology and blood biochemistry of a colony of free-living feral farm cats is presented. Samples and biochemical data were collected between late November and early December 1989 from 50-80 feral cats living on a farm in Oxfordshire, UK. A higher proportion of...
