  1. Preliminary analysis of an adjective-based dog personality questionnaire developed to measure some aspects of personality in the domestic dog (Canis familiaris)

    Contributor(s): Mirkó, Erika, Kubinyi, Enikő, Gácsi, Márta, Miklósi, Ádám

    In this paper we present a novel adjective-based dog personality questionnaire, which was successfully implemented to characterise the behaviour of individual dogs. The scales obtained by Principal Component Analysis (Stranger-directed Sociability, Activity, Aggressiveness and Trainability)...

  2. Preferences for overhead sprinklers by naïve beef steers: Test of two nozzle types

    Contributor(s): Parola, Fabia, Hillmann, Edna, Schütz, Karin E., Tucker, Cassandra B.

    Sprinklers effectively reduce heat load in cattle. In some studies, however, cattle readily use sprinklers, while others find that they either avoid or show no preference for it. These studies differ in many ways including previous experience of the animals and the amount of water delivered. Our...

  3. Preference of dairy cows: Indoor cubicle housing with access to a total mixed ration vs. access to pasture

    Contributor(s): Charlton, Gemma L., Rutter, Steven Mark, East, Martyn, Sinclair, Liam A.

    Cattle are grazing animals so it is generally assumed that pasture is a welfare friendly system as it is natural and allows the expression of normal behaviour, which may be restricted indoors. However, high yielding dairy cows may not be able to fulfil their nutritional demands from grass alone...

  4. Preference for structured environment in zebrafish (Danio rerio) and checker barbs (Puntius oligolepis)

    Contributor(s): Kistler, Claudia, Hegglin, Daniel, Würbel, Hanno, König, Barbara

    Information about the welfare and husbandry of pet and laboratory fish is scarce although millions of fish are sold in pet shops and used in laboratory research every year. Inadequate housing conditions can cause behavioural problems also in fish since they are complex animals with sophisticated...

  5. Preference and motivation for different diet forms and their effect on motivation for a foraging enrichment in captive Orange-winged Amazon parrots (Amazona amazonica)

    Contributor(s): Rozek, Jessica C., Millam, James R.

    Motivation tests were conducted to assess preference strength for diet form and a cage enrichment device by Orange-winged Amazon parrots (Amazona amazonica) held in individual cages, N=10. Each cage was equipped with two trough-type feeders, one of which had a hinged lid that required lifting to...

  6. Preference and demand for exercise in stabled horses

    Contributor(s): Lee, Joyce, Floyd, Toby, Erb, Hollis, Houpt, Katherine

    Operant conditioning and two choice preference tests were used to assess the motivation of horses to be released from straight and from box stalls. The motivations for food, a companion, and release into a paddock were compared when the horses had to work for each commodity at increasing fixed...

  7. Predictive validity of a method for evaluating temperament in young guide and service dogs

    Contributor(s): Duffy, Deborah L., Serpell, James A.

    As part of a collaborative project involving five guide and service dog organizations in the USA (Canine Companions for Independence, Guide Dogs for the Blind, Guiding Eyes for the Blind, Leader Dogs for the Blind and The Seeing Eye), volunteer puppy raisers provided information about the...

  8. Predicting sleep and lying time of calves with a support vector machine classifier using accelerometer data

    Contributor(s): Hokkanen, Ann-Helena, Hänninen, Laura, Tiusanen, Johannes, Pastell, Matti

    Sleep is essential to calves, but to date the only possibilities for measuring sleep in cattle production systems use ambulatory EEG or validated sleeping behavior assessments. We developed a small, neck-based, wireless accelerometer system for measuring the sleep and lying time of calves. We...

  9. Prandial correlations and the structure of feeding behaviour

    Contributor(s): Tolkamp, Bert J., Howie, Jennifer A., Bley, Tobias A. G., Kyriazakis, Ilias

    Prandial correlations measure the strength of the effects of between-meal interval length on the size of subsequent meals (pre-prandial) and vice versa (post-prandial) and provide insight into the control of food intake. In this paper we develop hypotheses about prandial correlations by using...

  10. The potential of the human–animal relationship as an environmental enrichment for the welfare of zoo-housed animals

    Contributor(s): Claxton, Anna M.

    Environmental enrichment strategies are used to improve both the physiological and psychological welfare of captive animals, which can be achieved by increasing the expression of natural behaviour and decreasing abnormal behaviours. Examples of successful environmental enrichment include the...

  11. Playful handling by caretakers reduces fear of humans in the laboratory rat

    Contributor(s): Cloutier, Sylvie, Panksepp, Jaak, Newberry, Ruth C.

    Handling of laboratory rats can increase physiological and emotional stress, leading to a fearful relationship with humans. We hypothesized that the affective quality of handling techniques used during routine care influences the animals’ fear of humans. We assessed responses of male...

  12. Physiological and welfare consequences of transport, relocation, and acclimatization of chimpanzees (Pan troglodytes)

    Contributor(s): Schapiro, Steven J., Lambeth, Susan P., Jacobsen, Kirsten Rosenmaj, Williams, Lawrence E., Nehete, Bharti N., Nehete, Pramod N.

    Manipulations of the environments of captive nonhuman primates often have welfare consequences to the animals, including behavioral effects, and for certain manipulations, physiological effects as well. The processes of transporting, relocating, and acclimatizing nonhuman primates across...

  13. Personality traits and the effects of DHA supplementation in the budgerigar (Melopsittacus undulatus)

    Contributor(s): Callicrate, Taylor Eilers, Siewerdt, Frank, Koutsos, Elizabeth, Estévez, Inma

    We investigated the hypotheses that a bold-shy personality axis exists in the budgerigar (Melopsittacus undulatus) and that dietary docosahexaenoic acid (DHA) supplementation has a significant effect on budgerigar personality and immune responses. DHA is an integral component of the brain known...

  14. Peat as environmental enrichment for piglets: The effect on behaviour, skin lesions and production results

    Contributor(s): Vanheukelom, Valerie, Driessen, Bert, Maenhout, Daniël, Geers, Rony

    The aim of this study was to examine whether the provision of small amounts of peat to piglets would influence behaviour and production. At approximately 5 days of age, nine litters received a tray of peat as enrichment, while nine others did not. All piglets had access to solid feed, which was...

  15. Parturition progress and behaviours in dairy cows with calving difficulty

    Contributor(s): Barrier, Alice C., Haskell, Marie J., Macrae, Alastair I., Dwyer, Cathy M.

    The welfare of dairy cows and their calves is compromised following a difficult calving. A better understanding of what happens during a difficult calving is needed to help prevent and alleviate adverse consequences through early diagnosis and/or pain mitigation. The objectives of this study were...

  16. Pain issues in poultry

    Contributor(s): Gentle, Michael J.

    This review highlights the possible pain experienced by layer and broiler poultry in modern husbandry conditions. Receptors which respond to noxous stimulation (nociceptors) have been identified and physiologically characterised in many different part of the body of the chicken including the...

  17. Pain and discomfort caused by parturition in cows and sows

    Contributor(s): Mainau, Eva, Manteca, Xavier

    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...

  18. Opioid control of behaviour in sheep: Effects of morphine and naloxone on food intake, activity and the affective state

    Contributor(s): Verbeek, Else, Ferguson, Drewe, Quinquet de Monjour, Patrick, Lee, Caroline

    The affective states of animals are important determinants of welfare, yet they are poorly understood. Here we investigate opioid involvement in the regulation of behaviours that may be indicative of the arousal and valence components of affective states in sheep. Ewes treated with sterile water...

  19. Object recognition and generalisation during habituation in horses

    Contributor(s): Christensen, Janne Winther, Zharkikh, Tatjana, Chovaux, Elodie

    The ability of horses to habituate to frightening stimuli greatly increases safety in the horse–human relationship. A recent experiment suggested, however, that habituation to frightening visual stimuli is relatively stimulus-specific in horses and that shape and colour are important factors for...

  20. Obedience training effects on search dog performance

    Contributor(s): Alexander, Michael Ben, Friend, Ted, Haug, Lore

    Competent search dogs should be accurate, reliable, and work independently, yet be responsive to handler commands. The aim of this study was to identify training factors that contribute to producing competent search dogs. Demographics, obedience training methods, the age training was initiated,...
