    Contributor(s):: Terlouw, E. M. C., Bourguet, C., Deiss, V.

  2. Survey of the incidence of post-stun behavioural reflexes in electrically stunned broilers in commercial conditions and the relationship of their incidence with the applied water-bath electrical parameters

  3. Does attention make the difference? Horses' response to human stimulus after 2 different training strategies

    Contributor(s):: Baragli, P., Mariti, C., Petri, L., Giorgio, F. de, Sighieri, C.

  4. Indicators of biodiversity and conservational wildlife quality on Danish organic farms for use in farm management: a multidisciplinary approach to indicator development and testing

    Contributor(s):: Noe, E., Halberg, N., Reddersen, J.

    Organic farming is expected to contribute to conserving national biodiversity on farms, especially remnant, old, and undisturbed small biotopes, forests, and permanent grassland. This objective cannot rely on the legislation of organic farming solely, and to succeed, farmers need to understand...

  5. Assessing the effects of a chronic stressor, stocking density, on welfare indicators of juvenile African catfish, Clarias gariepinus Burchell

    Contributor(s):: Nieuwegiessen, P. G. van de, Boerlage, A. S., Verreth, J. A. J., Schrama, J. W.

    Fish welfare is an area of increasing interest and stocking densities used in commercial aquaculture have been highlighted as a subject of specific welfare concern. The present study assessed how stocking density affects growth performance (final body weight, SGR, FCR), physiological (plasma...

  6. Behavioural analysis of solitary versus socially housed snow leopards ( Panthera uncia ), with the provision of simulated social contact

    Contributor(s):: Macri, A. M., Patterson-Kane, E.

    Activity budgets of 18 captive snow leopards were analyzed in order to assess the behaviour of cats housed singly versus those housed socially. Six solitary snow leopards and 12 socially housed snow leopards were compared. Pacing and activity level were used as indicators of the potential welfare...

  7. Breeding against harmful social behaviours in pigs and chickens: state of the art and the way forward

    Contributor(s):: Turner, S. P.

    Harmful social behaviours are prevalent in commercial farming environments and their reduction through economically feasible husbandry changes is challenging. Selective breeding may offer a complementary approach to reduce the expression of these traits. This article explores the progress made in...

  8. Cognitive bias as an indicator of animal emotion and welfare: emerging evidence and underlying mechanisms. (Special Issue: Animal suffering and welfare.)

    Contributor(s):: Mendl, M., Burman, O. H. P., Parker, R. M. A., Paul, E. S.

    Accurate assessment of animal emotion (affect) is an important goal in animal welfare science, and in areas such as neuroscience and psychopharmacology. Direct measures of conscious emotion are not available, so assessment of animal affect has relied on measures of the behavioural and...

  9. Consistency of individual variation in feeding behaviour and its relationship with performance traits in Nile tilapia Oreochromis niloticus

    Contributor(s):: Martins, C. I. M., Conceicao, L. E. C., Schrama, J. W.

    Feed intake is commonly used as one of the most important performance indicators in fish. However, very little is known about the behavioural processes involved in ingesting food such as meal duration, feeding frequency and latency to start eating. This study aims at the characterization of...

  10. Ear and tail postures as indicators of emotional valence in sheep. (Special Issue: Animal suffering and welfare.)

    Contributor(s):: Reefmann, N., Kaszas, F. B., Wechsler, B., Gygax, L.

    To date, most studies on animal emotions have focused on the assessment of negative emotional states, and there is a lack of approaches to characterising positive emotional states. The aim of this investigation was to measure differences in ear and tail postures in sheep exposed to situations...

  11. Effect of cage height on the welfare of growing rabbits

    Contributor(s):: Princz, Z., Radnai, I., Biro-Nemeth, E., Matics, Z., Gerencser, Z., Nagy, I., Szendro, Z.

    The objective of this study was to analyse the preference of rabbits for cages of various heights, their production and occurrence of ear lesions. Experiments were conducted at the University of Kaposvar with Pannon White rabbits. In experiments 1 and 2 (preference test) growing rabbits (n=112) -...

  12. Ethology applied to animal ethics. (Special Issue: Animal suffering and welfare.)

    Contributor(s):: Wurbel, H.

    According to modern animal welfare legislation, animals should be protected from suffering and lasting harm not for the benefit of us humans as in earlier anthropocentric conceptions, but in their own interest. The driving force behind animal protection is our empathy with animals which triggers...

  13. Eye white may indicate emotional state on a frustration-contentedness axis in dairy cows

    Contributor(s):: Sandem, A. I., Braastad, B. O., Boe, K. E.

    Research on welfare indicators has focused primarily on indicators of poor welfare, but there is also a need for indicators that can cover the range from good to poor welfare. The aim of this experiment was to compare behaviour elements in dairy cows shown in response to a frustrative situation...

  14. Fearfulness in horses: a temperament trait stable across time and situations

    Contributor(s):: Lansade, L., Bouissou, M. F., Erhard, H. W.

    The purpose of this study was to test the existence of a "fearfulness" trait in horses, by testing the stability across situations and over time of the responses to different fear-eliciting situations. It was also to identify which behavioural parameters are the best indicators of this trait....

  15. Feeding behaviour of sheep on shrubs in response to contrasting herbaceous cover in rangelands dominated by Cytisus scoparius L

    Contributor(s):: Pontes, L. da S., Agreil, C., Magda, D., Gleizes, B., Fritz, H.

    The foraging responses of ewes faced with a diversity of feed items and their effects on broom (Cytisus scoparius L.) consumption were examined. The experiment was conducted on a farm in the autumn with ewes (n=33) grazing three small paddocks (0.44 ha on average, for at least 10 days each)...

  16. 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...

  17. Measurement of feeding motivation in sheep and the effects of food restriction

    Contributor(s):: Verbeek, E., Waas, J. R., McLeay, L., Matthews, L. R.

    The availability of food is a crucial factor determining the health and growth of animals. Prolonged or severe food restriction will trigger the subjective state of hunger, which could potentially reduce welfare. We refined a methodology for the measurement of feeding motivation as an indicator...

  18. Pain and discomfort caused by parturition in cows and sows. (Special Issue: Pain in farm animals.)

    Contributor(s):: Mainau, E., Manteca, X.

    This review focuses on parturition as a painful process in cows and sows. Firstly, the different stages of parturition associated to the origin and transmission of pain stimuli are described. Hypoalgesia during the late pregnancy and parturition has been shown, perhaps as an endogenous defence...

  19. Pain and discomfort in male piglets during surgical castration with and without local anaesthesia as determined by vocalisation and defence behaviour

    Contributor(s):: Leidig, M. S., Hertrampf, B., Failing, K., Schumann, A., Reiner, G.

    Surgical castration of male piglets without anaesthesia is routine in domestic pig production causing serious distress and impairment of welfare. Thus, the EU is seeking alternatives, with local anaesthesia being one of the possible candidates. The aim of the present study was to compare surgical...

  20. Predicting tail-biting from behaviour of pigs prior to outbreaks

    Contributor(s):: Statham, P., Green, L., Bichard, M., Mendl, M.

    Predicting that an outbreak of tail-biting is going to occur in a group of pigs would be a useful tool for farmers. In a prospective longitudinal study, 24 groups of c.30 undocked pigs were followed from birth to slaughter weight. Four groups had to be excluded from the analysis, the remaining...
