  1. Environmentally enriching American mink ( Neovison vison) increases lymphoid organ weight and skeletal symmetry, and reveals differences between two sub-types of stereotypic behaviour

    Contributor(s):: Diez-Leon, M., Bursian, S., Galicia, D., Napolitano, A., Palme, R., Mason, G.

    Enrichment studies for wild carnivores (e.g., in zoos) are often short-term, use enrichments of unknown motivational significance, and focus on glucocorticoids and stereotypic behaviour (SB), ignoring other stress-relevant variables. Our study assessed the broad behavioural and physiological...

  2. Making the case for developing alternative lameness scoring systems for dairy goats

    Contributor(s):: Vieira, A., Oliveira, M. D., Nunes, T., Stilwell, G.

    Lameness is a behavioural indicator of pain that negatively affects dairy ruminants' health and welfare. Lameness is generally assessed by subjective methods, based on the observation of the animal's behaviour, using numerical rating scales (NRSs) - the most common scoring system - and visual...

  3. "Do not choose as I do!" - Dogs avoid the food that is indicated by another dog's gaze in a two-object choice task

    Contributor(s):: Balint, A., Farago, T., Meike, Z., Lenkei, R., Miklosi, A., Pongracz, P.

    Family dogs successfully follow human-given cues in a two-object choice test. However, whether this ability has any roots in dog-dog visual communication, has been seldom investigated. We designed a test where a video-projected, life-sized dog 'demonstrator' provided directional cues for the...

  4. Defining pacing quantitatively: a comparison of gait characteristics between pacing and non-repetitive locomotion in zoo-housed polar bears

    Contributor(s):: Cless, I. T., Voss-Hoynes, H. A., Ritzmann, R. E., Lukas, K. E.

    Pacing is a commonly investigated behavior in zoo animals, however, little data have been published to support a precise definition of pacing. High speed video of pacing behavior in 11 zoo-housed polar bears ( Ursus maritimus) was compared with goal-oriented locomotion in the same bears....

  5. Effect of feed allowance at pasture on lying behaviour and locomotory ability of dairy cows

    Contributor(s):: O'Driscoll, K., Lewis, E., Kennedy, E.

    In temperate climates where cows are primarily managed at pasture shortages of grass could result in nutritional deficits for the cow and thus pose a challenge to her welfare. This study investigated the effect of daily herbage allowance (DHA) on dairy cow lying behaviour, locomotory ability, and...

  6. Factors influencing stereotypic behaviours of animals rescued from Asian animal markets: a slow loris case study

    Contributor(s):: Moore, R. S., Cabana, F., Nekaris, K. A. I.

    Illegal wildlife trade has devastating effects on wild populations in Southeast Asia, made evident from the rising numbers of threatened species found in rescue centres. The prevalence of slow lorises ( Nycticebus spp.) in trade allows for the first time, a study of the response of wild-caught...

  7. Head partitions at the feed barrier affect behaviour of goats

    Contributor(s):: Nordmann, E., Barth, K., Futschik, A., Palme, R., Waiblinger, S.

    Space allowance at the feeding places often forces goats to feed in close proximity, that is, less than their individual distances. In consequence, agonistic behaviour may increase as well as stress and injuries, while access to feed may decrease, especially in low-ranking goats. Partitions...

  8. The relevance of variations in group size and phenotypic appearance on the behaviour and movement patterns of young domestic fowl

    Contributor(s):: Liste, G., Campderrich, I., Beltran Heredia, I. de, Estevez, I.

    Variations in the group size of laying hens might increase the risk of undesired behaviours with important consequences for the birds' health and welfare. However, larger groups housed at constant densities also translate into larger enclosures that may increase space efficiency, therefore...

  9. Young Blond d'Aquitaine, Angus and Limousin bulls differ in emotional reactivity: relationships with animal traits, stress reactions at slaughter and post-mortem muscle metabolism

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

    The present study investigated relationships between reactivity during tests, stress reactions at slaughter and animal traits in young Blond d'Aquitaine (BA), Limousin (LI) and Angus (AN) bulls. Behavioural and physiological reactivity of animals was evaluated during rearing using a "Human test"...

  10. Preliminary investigations into the ethological relevance of round-pen (round-yard) training of horses. (Special Issue: Equitation science.)

    Contributor(s):: Warren-Smith, A. K., McGreevy, P. D.

    Recently, training horses within round-pens has increased in popularity. Practitioners often maintain that the responses they elicit from horses are similar to signals used with senior conspecifics. To audit the responses of horses to conspecifics, 6 mare-young-horse dyads, this study introduced...

  11. A pilot study of sexual dimorphism in the head morphology of domestic dogs

    Contributor(s):: Carrasco, J. J., Georgevsky, D., Valenzuela, M., McGreevy, P. D.

    The dog ( Canis lupus familiaris) displays more morphological diversity than any other species. It is a direct descendant of the gray wolf ( Canis lupus), but shows remarkable behavioral and morphological differences. It has been suggested that differences in skull shape that relate to brain...

  12. Aggressiveness in the domestic fowl: Distance versus 'attitude'

    | Contributor(s):: Rodriguez-Aurrekoetxea, A., Estevez, I.

    It has been suggested that invasion of the personal space by flock members is the main trigger of aggressive interactions in the domestic fowl ( Gallus gallus domesticus). In large and dense groups of birds high frequency of attacks should be expected as the chances of invading the personal...

  13. Assessing ridden horse behavior: professional judgment and physiological measures

    | Contributor(s):: Hall, C., Kay, R., Yarnell, K.

    The assessment of ridden horse behavior by 12 equestrian professionals (riding instructors n=4, riders n=4, veterinarians n=4) was compared with observed behavior and physiological measures (salivary cortisol and eye temperature). Horses (n=10) were ridden at walk, trot, and canter in a...

  14. Assessment of ridden horse behavior

    | Contributor(s):: Hall, C., Huws, N., White, C., Taylor, E., Owen, H., McGreevy, P.

    Assessments of the behavior of ridden horses form the basis of performance evaluation. The purpose of any performance being evaluated will determine the factors considered important, factors indicative of "poor" performance, and what makes a successful equine athlete. Currently, there is no...

  15. Behavioral and cardiac responses by dogs to physical human-dog contact

    | Contributor(s):: Kuhne, F., Hossler, J. C., Struwe, R.

    Measures of behavioral responses and cardiovascular parameters to evaluate and assess animal well-being are well established. A major aspect of companion animal well-being seems to originate from direct human-animal interaction. For pet dogs, the manner in which they obtain and respond to petting...

  16. Perception of dogs' stress by their owners

    | Contributor(s):: Mariti, C., Gazzano, A., Moore, J. L., Baragli, P., Chelli, L., Sighieri, C.

    Questionnaires potentially have a broad applicability in measuring stress levels in dogs, as owners know their dogs' behavior and personality better than anyone else. The aim of this research was to evaluate how owners perceive stress in their dogs through understanding of displayed behaviors....

  17. Vocal recognition of owners by domestic cats ( Felis catus)

    | Contributor(s):: Saito, A., Shinozuka, K.

    Domestic cats have had a 10,000-year history of cohabitation with humans and seem to have the ability to communicate with humans. However, this has not been widely examined. We studied 20 domestic cats to investigate whether they could recognize their owners by using voices that called out the...

  18. The response of dogs to attentional focus of human beings: a comparison between guide dog candidates and other dogs

    | Contributor(s):: Yamamoto, M., Ohtani, N., Ohta, M.

    Dogs that are trained without dependence on the attentional focus of human beings (experimental group: a guide dog and guide dog candidates) were compared with those trained with the usual level of attentional focus (control group: a service dog, service dog candidates, a search and rescue dog,...

  19. Behaviour, synchrony and welfare of Pekin ducks in relation to water use

    | Contributor(s):: Waitt, C., Jones, T., Dawkins, M. S.

    The method of providing bathing water to commercially farmed ducks presents potential logistic, welfare and health issues. Welfare may be compromised if ducks do not have access to water in which they can at least dip their heads and spread water over their feathers. However maintaining hygiene...

  20. Correlates of self-directed and stereotypic behaviours in captive red-capped mangabeys ( Cercocebus torquatus torquatus )

    | Contributor(s):: Reamer, L., Tooze, Z., Coulson, C., Semple, S.

    The quantification of behaviours linked to anxiety or stress provides a powerful means to address applied questions related to the well-being of captive animals. This study explored correlates of two such behaviours - self-directed (SDB) and stereotypic behaviour (STB) - among captive red-capped...
