  10. Aggression and social spacing in light horse ( Equus caballus ) mares and foals

    Contributor(s):: Weeks, J. W., Crowell-Davis, S. L., Caudle, A. B., Heusner, G. L.

    Aggression and social spacing were studied in 14 light horse mares and their foals living at pasture. Focal samples were collected on each mare-foal dyad for 6 to 10.5 h from 2 months of foal age until weaning at approximately 4 months of age. Observations on foals continued until approximately 6...

  11. Agonistic behaviour after mixing in pigs under commercial farm conditions

    Contributor(s):: Stukenborg, A., Traulsen, I., Puppe, B., Presuhn, U., Krieter, J.

    The aim of the study was to investigate agonistic behaviour of pigs after regrouping pigs under commercial sow farm conditions. The behavioural patterns were observed over a 48-h period, directly after weaning (PIG-28; n=647) and 40 days later (growing pigs, PIG-68; n=224). Agonistic interactions...

  12. Agonistic behaviour and feather pecking in single-sexed and mixed groups of laying hens

    Contributor(s):: Oden, K., Vestergaard, K. S., Algers, B.

    The effects of the presence of males on female aggressiveness and feather pecking in groups of about 500 laying hens housed in an aviary system were studied. In all, 10 groups of ISA Brown laying hens were observed at 21, 35, 45 and 55 weeks of age on 2 farms, during 2 years. In the second year,...

  13. Agonistic interactions and physiological reactions of top- and bottom-ranking pigs confronted with a familiar and an unfamiliar group: preliminary results

    Contributor(s):: Otten, W., Puppe, B., Stabenow, B., Kanitz, E., Schon, P. C., Brussow, K. P., Nurnberg, G.

    Four trials were carried out, where in each trial during a selection test 2 groups of growing pigs (12 weeks old) with 9 animals each were randomly formed. After a week, the top (TR) and bottom (BR) ranking pig from each group was isolated and kept under single housing conditions. At the age of...

  14. Alternative housing for sows and litters. Part 4. Effects of sow-controlled housing combined with a communal piglet area on pre- and post-weaning behaviour and performance

    Contributor(s):: Weary, D. M., Pajor, E. A., Bonenfant, M., Fraser, D., Kramer, D. L.

    Previous experimental work has shown modest and variable production and welfare benefits for the lactating sow and piglets when sows are allowed to separate themselves temporarily from their piglets, or when piglets have access to a communal creep area sufficiently attractive that they spend...

  15. An investigation into the effect of different protein and energy intakes on model tail chewing behaviour of growing pigs

    Contributor(s):: McIntyre, J., Edwards, S. A.

    Twenty-four crossbred pigs were housed individually and allocated at 62 kg (S.E.M.=0.81) to one of three diets providing differing daily protein and energy intakes: control (C) 1.42 g CP/MJ DE, fed to provide 2.85 maintenance energy; low protein (LP) 0.76 g CP/MJ DE fed to provide the same daily...

  16. Behaviour patterns and time course of activity in dogs with separation problems

    Contributor(s):: Lund, J. D., Jorgensen, M. C.

    An analysis of video-recordings of 20 dogs with separation problems suggested that separation behaviour may be divided into; exploratory behaviour, object play including elements of predatory behaviour, destructive behaviour and vocalization. Elimination behaviour was only found in one case....

  17. Behavioural characteristics of two dairy breeds of cows selected ( Herens ) or not ( Brune des Alpes ) for fighting and dominance ability

    Contributor(s):: Plusquellec, P., Bouissou, M. F.

    Two breeds of dairy cattle, one selected for intra-specific fighting and dominance ability (Herens, H), the other not selected for this behavioural trait (Brune des Alpes, BA), submitted to the same management techniques, were compared with respect to their social behaviour (dominance, agonistic...

  18. Behavioural variation in cultivated juvenile Atlantic cod ( Gadus morhua L.) in relation to stocking density and size disparity

    Contributor(s):: Uglem, I., Kjorsvik, E., Gruven, K., Lamberg, A.

    The aim of this study was to examine the behaviour and activity of Atlantic cod (Gadus morhua) juveniles (~65-120 mm total length) in relation to varying stocking density (~500-2000 fish per m3) and size disparity under both experimental and commercial hatchery conditions. This was done by using...

  19. Cannibalism in juvenile blue-swimmer crabs Portunus pelagicus (Linnaeus, 1766): effects of body size, moult stage and refuge availability

    Contributor(s):: Marshall, S., Warburton, K., Paterson, B., Mann, D.

This study was undertaken to improve blue-swimmer crab culture and experimentally addressed (1) prey vulnerability (2)...

  20. Consistency of individual behavioural characteristics of dairy cows in their home pen

    Contributor(s):: Schrader, L.

    The aim of this study was to identify reliable individual behavioural characteristics of dairy cows based on aspects of their spontaneous behaviour and their reactions towards behavioural tests performed in their home pen. The parameters measured were supposed to reflect how easily the behaviour...
