  1. Blue foxes’ (Vulpes lagopus) motivation to gain access and interact with various resources

    Contributor(s):: Koistinen, Tarja, Korhonen, Hannu T., Hämäläinen, Elina, Mononen, Jaakko

    We analysed the willingness of blue foxes (Vulpes lagopus) to work for and utilise five resources: a platform, wooden block, sand floor, nest box and empty space. Ten juvenile blue fox males were housed singly in apparatus consisting of three cages connected with one-way doors through the walls...

  3. Behaviour and welfare of veal calves fed different amounts of solid feed supplemented to a milk replacer ration adjusted for similar growth

    Contributor(s):: Webb, L. E., Bokkers, E. A. M., Engel, B., Gerrits, W. J. J., Berends, H., Reenen, C. G. van

  4. Feeding Chromonaela odorata during pregnancy to goat dams affects acceptance of this feedstuff by their offspring

    Contributor(s):: Phan Vu, Hai, Everts, H., Dam Van, Tien, Schonewille, J. T., Hendriks, W. H.

  5. Behavioral and physiological predictors of guide dog success

    Contributor(s):: Tomkins, L. M., Thomson, P. C., McGreevy, P. D.

    A range of mobility aids are available to assist people living with vision impairment, and of these, guide dog ownership offers them several unique benefits. However, training a dog to be a successful guide dog comes at a high cost (approximately AU$30,000). Therefore, the aim of this study was...

  6. Learning emotion recognition from canines? Two for the road

    Contributor(s):: Stetina, B. U., Turner, K., Burger, E., Glenk, L. M., McElheney, J. C., Handlos, U., Kothgassner, O. D.

    The ability to recognize emotions is a prerequisite for interpersonal interaction and essential for emotional competencies. The present study aimed at exploring the possibility of enhancing the emotion recognition capability of human beings by using an animal-assisted intervention focusing on...

  7. Domestic pigs alter their social strategy in response to social group size

    Contributor(s):: Samarakone, T. S., Gonyou, H. W.

    In a series of studies, we investigated the concept that domesticated pigs may adopt cost efficient social strategies, in which individuals become less aggressive due to a higher number of potential competitors, in large social groups. Six blocks, each comprising four pens of 18 pigs (small...

  8. Effects of early contact between non-littermate piglets and of the complexity of farrowing conditions on social behaviour and weight gain

    Contributor(s):: Kutzer, T., Bunger, B., Kjaer, J. B., Schrader, L.

    In this study we tested if contact possibilities between non-littermate piglets and complexity of farrowing conditions affect the pre- and post-weaning behaviour, weight gain and skin lesions of piglets. Suckling sows were either kept in a group housing system (GH), in a single pen loose housing...

  9. Evaluating methods of gas euthanasia for laboratory mice

    Contributor(s):: Makowska, I. J., Vickers, L., Mancell, J., Weary, D. M.

    Laboratory mice are most commonly killed with carbon dioxide (CO2), a gas they may find aversive. The aim of this study was to use approach-avoidance testing to record mouse responses to CO2 and to four alternatives: argon, carbon monoxide (CO), and the inhalant anaesthetics halothane and...

  10. Handling-induced tonic/clonic seizures in captive born bank voles ( Clethrionomys glareolus )

    Contributor(s):: Schonecker, B.

    Handling-induced seizures observed among 23 of 333 captive born bank voles was characterized by tonic/clonic convulsions, occasionally accompanied by an apparent loss of consciousness. Seizures were never observed among wild caught voles (N=71). Median age for first observation of seizures was...

  11. How does the method used to feed lambs modulate their affinity to their human caregiver?

    Contributor(s):: Tallet, C., Veissier, I., Boivin, X.

    Feeding young mammals is often used as a way to increase their affinity to their human caregiver. However, feeding is not always necessary, which raises questions as to the feeding method used (bottle, bucket) and to the importance of contacts surrounding feeding compared to an absence of human...

  12. Individual differences in cortisol levels and behaviour of Senegalese sole ( Solea senegalensis ) juveniles: evidence for coping styles

    Contributor(s):: Silva, P. I. M., Martins, C. I. M., Engrola, S., Marino, G., Overli, O., Conceicao, L. E. C.

    Individual variation in stress physiology and behaviour has been previously reported in several fish species. As seen in other vertebrates, existence of stress coping styles seems to be reflected by the presence of individual variation. Aggressive behaviour, amongst others, is one of the most...

  13. Influence of maternal undernutrition on the behaviour of juvenile lambs

    Contributor(s):: Simitzis, P. E., Charismiadou, M. A., Kotsampasi, B., Papadomichelakis, G., Christopoulou, E. P., Papavlasopoulou, E. K., Deligeorgis, S. G.

    The objective of the present experiment was to determine the implications of prenatal undernutrition on the behaviour of juvenile lambs. Dams of one group (C) were fed 100% of the recommended requirements throughout pregnancy, while those of two other groups were fed 50% of the control nutrient...

  14. Sow behaviour towards humans during standard management procedures and their relationship to piglet survival

    Contributor(s):: Lensink, B. J., Leruste, H., Bretagne, T. de, Bizeray-Filoche, D.

    Piglet crushing remains a major problem in pig production and is partly related to sow behavioural traits. The sows' responses to the presence of humans around farrowing could partly contribute to piglet crushing through increased reactivity and getting up and lying down behaviour. The aim of the...

  15. The combined effects of milking frequency and feeding level on dairy goat welfare and milk emission characteristics in late lactation

    Contributor(s):: Komara, M., Giger-Reverdin, S., Marnet, P. G., Roussel, S., Duvaux-Ponter, C.

    This study investigated the combined effects of once-daily milking and feeding level (ad libitum or adjusted) on goat welfare and milk emission characteristics in late lactation. Forty dairy goats housed in individual pens were managed under twice-daily milking and fed ad libitum during a...

  16. The effect of litter condition and depth on the suitability of wood shavings for dustbathing behaviour

    Contributor(s):: Moesta, A., Knierim, U., Briese, A., Hartung, J.

    Although several studies show that fresh wood shavings (FW) are not well-suited as dustbathing substrate for laying hens, little is known about the suitability of wood shavings used as litter in non-cage systems for several weeks (used wood shavings, UW) and the effect of different substrate...

  17. Video analysis of dogs with separation-related behaviors

    Contributor(s):: Palestrini, C., Minero, M., Cannas, S., Rossi, E., Frank, D.

    Separation-related behaviors are described as problematic behaviors that occur exclusively in the owner's absence or virtual absence. Diagnosis is generally based on indirect evidence such as elimination or destruction that occurs during owner absence. Questionnaire studies are based on owner...

  18. Do horses generalise between objects during habituation?

    Contributor(s):: Christensen, J. W., Zharkikh, T., Ladewig, J.

    Habituation to frightening stimuli plays an important role in horse training. To investigate the extent to which horses generalize between different visual objects, 2-year-old stallions were habituated to feeding from a container placed inside a test arena and assigned as TEST (n=12) or REFERENCE...

  19. Does pecking at inanimate stimuli predict cannibalistic behaviour in domestic fowl?

    Contributor(s):: Cloutier, S., Newberry, R. C., Forster, C. T., Girsberger, K. M.

    The pecking behaviour of caged White Leghorn hens towards feather-shaped stimuli varying in colour (red or blue), material (paper or feather) and movement (stationary or movable) attached to a board placed in the feed trough was assessed. Each of the eight stimulus combinations was presented to...

  20. Measuring cutaneous thermal nociception in group-housed pigs using laser technique - effects of laser power output. (Special Issue: Animal suffering and welfare.)

    Contributor(s):: Herskin, M. S., Ladewig, J., Arendt-Nielsen, L.

    Nociceptive testing is a valuable tool in the development of pharmaceutical products, for basic nociceptive research, and for studying changes in pain sensitivity is investigated after inflammatory states or nerve injury. However, in pigs only very limited knowledge about nociceptive processes...
