    Contributor(s):: Wanser, S. H., MacDonald, M., Udell, M. A. R.

  2. Inside the Interaction: Contact With Familiar Humans Modulates Heart Rate Variability in Horses

    Contributor(s):: Scopa, C., Greco, A., Contalbrigo, L., Fratini, E., Lanatà, A., Scilingo, E. P., Baragli, P.

  3. The Power of a Positive Human-Animal Relationship for Animal Welfare

    Contributor(s):: Rault, J. L., Waiblinger, S., Boivin, X., Hemsworth, P.

  4. Behavioural variation among divergent European and North American farmed and wild Atlantic salmon (Salmo salar) populations

    Contributor(s):: Islam, Shahinur S., Wringe, Brendan F., Bradbury, Ian R., Fleming, Ian A.

    Animals often display consistent differences in behaviours across situations and contexts. However, little is known about how behavioural traits might vary in a context-dependent manner, with selection favouring correlated sets of behaviours in particular types of environments. Comparative...

  5. Different regrouping schedules in semi group-housed rabbit does: Effects on agonistic behaviour, stress and lesions

    Contributor(s):: Braconnier, Michèle, Gómez, Yamenah, Gebhardt-Henrich, Sabine G.

    Although group housing of naturally social animals like rabbits (Oryctolagus cuniculus) is desirable for ethical reasons, social conflicts can significantly increase the risk for injuries as well as stress incidences and negatively affect their welfare. A common housing system in Switzerland is...

  6. The ability of artisanal fishers to recognize the dolphins they cooperate with

    Contributor(s):: da Rosa, D. S. X., Hanazaki, N., Cantor, M., Simoes-Lopes, P. C., Daura-Jorge, F. G.

  7. Refuge use affects daily activity patterns in female Xenopus laevis

    Contributor(s):: Archard, Gabrielle A.

    The African clawed frog (Xenopus laevis) is widely used for scientific research, but its ecology and behavior are poorly understood. In two experiments, the 24h activity patterns of female X. laevis were monitored. In the first, activity was determined both in the presence and absence of a...

  8. Interspecific interactions and welfare implications in mixed species communities of capuchin (Sapajus apella) and squirrel monkeys (Saimiri sciureus) over 3 years

    Contributor(s):: Buchanan-Smith, Hannah M., Griciute, Joana, Daoudi, Sophia, Leonardi, Rebecca, Whiten, Andrew

    Species have complex relationships with others in the wild, and some such as capuchin (Sapajus apella) and squirrel monkeys (Saimiri sciureus) naturally choose to associate with each other. There are a number of benefits of exhibiting such species in correspondingly mixed communities in captivity...

  9. Factors influencing the welfare of goats in small established groups during the separation and reintegration of individuals

    Contributor(s):: Patt, Antonia, Gygax, Lorenz, Wechsler, Beat, Hillmann, Edna, Palme, Rupert, Keil, Nina M.

    As a goat's separation from or reintegration into its group is likely to have an adverse effect on the welfare of both the separated goat and the remaining goats in the group, management procedures need to be carried out in a way that minimises their negative impact. In the present study, we...

  10. Dynamics of the access of captive domestic cats to a feed environmental enrichment item

    Contributor(s):: Damasceno, Juliana, Genaro, Gelson

    Providing feed enrichment to captive felids that are obligate carnivores is crucial for eliciting natural hunting behaviours. However, studies of the efficacy of enrichment techniques usually analyse the whole group, overlooking the different behaviours of individual animals towards the enriched...

  11. Behavioural and physiological reactions of goats confronted with an unfamiliar group either when alone or with two peers

    Contributor(s):: Patt, Antonia, Gygax, Lorenz, Wechsler, Beat, Hillmann, Edna, Palme, Rupert, Keil, Nina M.

    When introduced into a new herd, goats are confronted with unfamiliar animals. Their behavioural and physiological reactions during this confrontation are likely to differ depending on the presence or absence of familiar conspecifics (peers). To assess these reactions, we confronted 12 goats both...

  12. Association between taxonomic relatedness and interspecific mortality in captive ungulates

    Contributor(s):: Hanzlíková, Veronika, Pluháček, Jan, Čulík, Luděk

    Interspecific aggressive interactions are known among a variety of animals including ungulates. Nevertheless, most studies on interspecific interactions in ungulates involve case reports without testing any specific hypotheses. We tested two mutually exclusive hypotheses; that mortality rate in...

  13. Regrouping rabbit does in a familiar or novel pen: Effects on agonistic behaviour, injuries and core body temperature

    Contributor(s):: Graf, Sylvia, Bigler, Lotti, Failing, Klaus, Würbel, Hanno, Buchwalder, Theres

    Regrouping female rabbits in group-housing systems is common management practice in rabbit breeding, which may, however, induce agonistic interactions resulting in social stress and severe injuries. Here we compared two methods of regrouping female rabbits with respect to their effects on...

  14. The introduction of individual goats into small established groups has serious negative effects on the introduced goat but not on resident goats

    Contributor(s):: Patt, Antonia, Gygax, Lorenz, Wechsler, Beat, Hillmann, Edna, Palme, Rupert, Keil, Nina M.

    The introduction of an individual goat into an established group is likely to result in intense agonistic interactions, which may adversely affect the welfare of both the introduced goat and the resident goats. To assess this situation, we introduced eight horned and eight hornless goats one at a...

  15. Effects of social dominance, water trough location and shade availability on drinking behaviour of cows on pasture

    Contributor(s):: Coimbra, Paula Araujo Dias, Machado Filho, Luiz Carlos Pinheiro, Hötzel, Maria José

    The effects of water trough location and presence of shade on the behaviour of cows on pasture were investigated. The impact of social hierarchy on cows’ use of shade and the water trough was also investigated. Thirty two non-pregnant dry cows were randomly divided in four groups in a 4×4 Latin...

  16. The effects of mixed-species assemblage on the behaviour and welfare of fish held in home aquaria

    Contributor(s):: Sloman, Katherine A., Baldwin, Louise, McMahon, Stanley, Snellgrove, Donna

    While there is growing scientific research into the welfare of fish held under aquaculture conditions, there has been little research into the welfare of ornamental fish kept in home aquaria. With the ever increasing popularity of home aquaria, there is now an urgent need to address our current...

  17. Effects of group stability on aggression, stress and injuries in breeding rabbits

    Contributor(s):: Andrist, Claude A., Bigler, Lotti M., Würbel, Hanno, Roth, Beatrice A.

    On Swiss rabbit breeding farms, group-housed does are usually kept singly for 12 days around parturition to avoid pseudogravidity, double litters and deleterious fighting for nests. After this isolation phase there is usually an integration of new group members. Here we studied whether keeping...

  18. Dry sows in dynamic groups: An investigation of social behaviour when introducing new sows

    Contributor(s):: Krauss, Verena, Hoy, Steffen

    In the investigation 22 groups of sows (with a total number of 73 sows, being partially observed repeatedly) were consecutively observed for 96h with the aid of video technology after the introduction of 5 new sows into a group of 10 resident sows, thus creating a dynamic group of 15 animals. The...

  19. Group size and phenotypic appearance: Their role on the social dynamics in pullets

    Contributor(s):: Campderrich, Irene, Liste, Guiomar, Estevez, Inma

    Non-caged production systems offer greater freedom of movement and behavioural opportunities to pullets, which may also include the occurrence of undesired behaviours. The incidence of such behaviours may be affected by group size but also by the group memberś phenotype. This study was designed...

  20. Gentle interactions decrease the fear of humans in dairy heifers independently of early experience of stroking

    Contributor(s):: Lürzel, Stephanie, Windschnurer, Ines, Futschik, Andreas, Waiblinger, Susanne

    The relationship of farmed animals with humans has important implications for animal welfare and productivity. To investigate the short- and long-term effect of gentle interactions (stroking, talking in a gentle voice) during different life stages on the fear of humans, we tested heifers that had...
