  1. Effects of confinement duration and parity on behavioural responses and the degree of psychological fear in pregnant sows

    Contributor(s):: Zhang, Ming-yue, Li, Xiang, Zhang, Xiao-hui, Liu, Hong-gui, Li, Jian-hong, Bao, Jun

    The aim of this study was to evaluate the effects of space restriction stress on the behavior of different parity sows, and it is necessary to understand such effects due to space restriction to improve the welfare of the sows in confined conditions. We selected 264 pregnant sows (Large White) at...

  2. Effect of enclosure quality on reactivity and welfare of captive Soemmerring's gazelle ( Gazella soemmerringii )

    Contributor(s):: Mansour, A. A. H., Zakaria, A. H., Fraser, A. F.

    The welfare of nonhuman animals in zoos is a great challenge to the zookeeper. Changes in the behavioral response of captive animals to their immediate environment can be used as a method for evaluating their welfare status. This study evaluates reactive responses of 3 groups of captive...

  3. How "natural" training methods can affect equine mental state? A critical approach - a review

    Contributor(s):: Rozempolska-Rucinska, I., Trojan, M., Kosik, E., Prochniak, T., Gorecka-Bruzda, A.

  4. Human-animal interaction, stress, and embryo production in Bos indicus embryo donors under tropical conditions

    Contributor(s):: Macedo, G. G., Zuccari Neto, C. E. S., Abreu, U. G. P. de, Negrao, J. A., Costa e Silva, E. V. da

    This study investigated the effect of human-animal interaction (HAI) and the stress response on the quality of embryo production in superovulated Nelore (Bos indicus) cattle, under tropical conditions. Thirty-two females underwent a superovulation protocol for 5 days. Cortisol concentrations were...

  5. Non-pharmacological approaches for dementia that informal carers might try or access: a systematic review

    Contributor(s):: Hulme, C., Wright, J., Crocker, T., Oluboyede, Y., House, A.

  6. Exploration behaviour and flight response toward a stimulus in three sea bass strains ( Dicentrarchus labrax L.)

    Contributor(s):: Millot, S., Begout, M. L., Chatain, B.

    Domestication and selection may affect fish behaviour, sometime as soon as at the first generation of domestication. However, knowledge about how both processes impact on fish spatial exploration and swimming activity still is to be improved. The objective of this experiment was (i) to evaluate...

  7. Oxytocin facilitates behavioural, metabolic and physiological adaptations during lactation. (Special issue: Suckling)

    Contributor(s):: Uvnas-Moberg, K., Johansson, B., Lupoli, B., Svennersten-Sjaunja, K.

    This article aims to propose that oxytocin not only stimulates milk letdown, but also adapts behaviour and physiology to facilitate lactation in mammals, including dairy cattle. Circulating oxytocin as well as neurogenic oxytocin participates in these regulatory processes. In short, oxytocin...

  8. Sensory sensitivities: components of a horse's temperament dimension

    Contributor(s):: Lansade, L., Pichard, G., Leconte, M.

    Temperament is an important factor when working with horses. Behavioural tests have already been developed to measure certain dimensions of a horse's temperament (fearfulness, gregariousness, etc.). In order to measure the temperament more precisely, our work aimed to identify a dimension which...

  9. Sensory stimulation as environmental enrichment for captive animals: a review

    Contributor(s):: Wells, D. L.

    In the wild, animals are exposed to an ever-changing array of sensory stimuli. The captive environment, by contrast, is generally much more impoverished in terms of the sensory cues it offers the animals housed within. In a bid to remedy this, and promote better welfare, researchers have started...

  10. 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...

  11. Thermonociception in fish: effects of two different doses of morphine on thermal threshold and post-test behaviour in goldfish ( Carassius auratus )

    Contributor(s):: Nordgreen, J., Garner, J. P., Janczak, A. M., Ranheim, B., Muir, W. M., Horsberg, T. E.

    The question of whether fish can perceive pain is controversial, and pain is a potentially grave threat to fish welfare. To be able to study pain in a species, knowledge of its nociceptive system is necessary. There is therefore a need for standardised, repeatable and quantifiable measures of...

  12. 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...

  13. 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...

  14. Physical contact while handling is not necessary to reduce fearfulness in the rabbit

    Contributor(s):: Ducs, A., Bilko, A., Altbacker, V.

    Rabbits handled around nursing time during the first week after birth show reduced fear response toward humans. Our earlier attempt to reduce the duration of daily treatment necessary to achieve this effect showed that even a minimal human contact, characteristic of animal caretaking in intensive...

  15. The influence of olfactory stimulation on the behaviour of cats housed in a rescue shelter

    Contributor(s):: Ellis, S. L. H., Wells, D. L.

    A wide variety of feline species have been shown to gain welfare benefits from the introduction of olfactory stimuli to the captive environment. The effect of this stimulation on the domestic cat, however, has been largely overlooked. This study thus explored the influence of olfactory...

  16. Selective attention to humans in companion dogs, Canis familiaris

    Contributor(s):: Mongillo, P., Bono, G., Regolin, L., Marinelli, L.

    Integration into human societies requires dogs to express adaptable social attitudes, involving high levels of attention to other individuals. In the present study, we developed a new behavioural test, to characterize selective attention towards humans. In the task, the dogs were exposed to the...

  17. Habituation and extinction in an approach-avoidance test: an example with sheep

    Contributor(s):: Erhard, H. W., Elston, D. A., Davidson, G. C.

    During a behavioural test, the test animal's perception of the test situation may change, e.g. as a result of habituation. This change can occur within a test or between repetitions of a test. It is particularly important in the arena test because in an approach-avoidance situation, the negative...
