  1. Clinical signs caused by the use of electric training collars on dogs in everyday life situations

    Contributor(s):: Schalke, E., Stichnoth, J., Ott, S., Jones-Baade, R.

    The use of electric shock collars for training dogs is the subject of considerable controversy. Supporters claim that they are a reliable means of eliminating self-rewarding behaviour and that they can be used over greater distances and with less risk of stress and injury than mechanical devices,...

  2. Neonatal foal handling

    Contributor(s):: Simpson, B. S.

    Recent interest has focused on the advantage of intensively handling young foals as a means of producing more tractable horses, accustomed to humans and receptive to training. To date, the effect of this intensive handling, dubbed imprint training in the popular literature, is not tested. The...

  3. The effects of air transport on the behaviour and heart rate of horses

    Contributor(s):: Stewart, M., Foster, T. M., Waas, J. R.

    Although many horses (Equus caballus) travel by air, there is little information on the effect of this type of transport on their physiology and behaviour. This study monitored the behaviour and heart rate of horses during air transport to identify events that might be stressful and to compare...

  4. Behaviour and physiologic responses of mares to short-term isolation

    Contributor(s):: Strand, S. C., Tiefenbacher, S., Haskell, M., Hosmer, T., McDonnell, S. M., Freeman, D. A.

    The aim of this study was to evaluate the behaviour and physiologic responses of mares to removal from an established pasture herd and to isolation in a pasture setting for 6 h (Group I, n=5). Responses of mares in Group I were compared to mares that were transported and returned to the herd...

  5. Familiarity and group size affect emotional stress in Japanese Black heifers

    Contributor(s):: Takeda, K., Sato, S., Sugawara, K.

    We compared behavioural and cardiac responses to emotional stresses between familiar and unfamiliar heifers in groups of two or five. Fourteen Japanese Black heifers were divided into two experimental groups of two individuals (F2) and two groups of five individuals (F5) that were familiar with...

  6. Development of the attachment bond in guide dogs

    Contributor(s):: Valsecchi, P., Previde, E. P., Accorsi, P. A., Fallani, G.

    This study investigates ontogenetic aspects of attachment behaviour in guide dogs using the Strange Situation Test (SST). Seventeen dogs were tested three times in different periods of the guide dog training program. The first test was carried out when the dogs were 11-15 months old and before...

  7. Learning performances in young horses using two different learning tests

    Contributor(s):: Visser, E. K., Reenen, C. G. van, Schilder, M. B. H., Barneveld, A., Blokhuis, H. J.

    To achieve optimal performance in equine sports as well as in leisure not only the physical abilities of the horse should be considered, but also the horse's personality. Besides temperamental aspects, like emotionality, or the horse's reactivity towards humans in handling situations, the...

  8. Previous handling and gentle interactions affect behaviour and heart rate of dairy cows during a veterinary procedure

    Contributor(s):: Waiblinger, S., Menke, C., Korff, J., Bucher, A.

    Veterinary and management procedures often are aversive to the animals, resulting in physiological and behavioural stress reactions, which increase the risk of accidents and might lower performance. We investigated the effects of previous positive handling and of gentle interactions during the...

  9. The response of beef cattle to noise during handling

    Contributor(s):: Waynert, D. F., Stookey, J. M., Schwartzkopf-Genswein, K. S., Watts, J. M., Waltz, C. S.

    59 yearling beef heifers (362+or-26 kg) were used in a study to evaluate their behavioural and physiological response to noises during a 1 min exposure. In Trial 1, 29 heifers that were naive to the treatments were assigned to either prerecorded handling noise (Noise, n=14) composed of humans...

  10. Three-dimensional analysis of horse and human gaits in therapeutic riding

    Contributor(s):: Uchiyama, H., Ohtani, N., Ohta, M.

    Therapeutic horse riding or hippotherapy is used as an intervention for treating individuals with mental and physical disabilities. Equine-assisted interventions are based on the hypothesis that the movement of the horse's pelvis during horseback riding resembles human ambulation, and thus...

  11. Towards a more objective assessment of equine personality using behavioural and physiological observations from performance test training

    Contributor(s):: Borstel, U. K. von, Pasing, S., Gauly, M.

    Current definitions of horse personality traits are rather vague, lacking clear, universally accepted guidelines for evaluation in performance tests. Therefore, the aim of the present study was to screen behavioural and physiological measurements taken during riding for potential links with...

  12. Physiological and behavioural alterations in disbudded goat kids with and without local anaesthesia

    Contributor(s):: Alvarez, L., Nava, R. A., Ramirez, A., Ramirez, E., Gutierrez, J.

    The physiological and behavioural responses were evaluated in goat kids that were disbudded either with or without local anaesthesia, in a study with 56 animals randomly allocated among five groups. The anaesthesia/disbudding group (AD, n=12) was treated with 2 mL 2% lidocaine (L2

  13. Some effects of repeated handling and the use of a mask on stress responses in zebu cattle during restraint

    Contributor(s):: Andrade, O., Orihuela, A., Solano, J., Galina, C. S.

    The objective of this investigation was to evaluate the effect of repeated handling and the use of a mask on the order of entry, temperament, cortisol concentration and heart and respiratory rates of Brahman cattle during restraint in a squeeze chute. In the first experiment, 18 cows were...

  14. Behavioural and physiological responses to an acute stressor in crib-biting and control horses

    Contributor(s):: Bachmann, I., Bernasconi, P., Herrmann, R., Weishaupt, M. A., Stauffacher, M.

    The responses of eleven pairs of crib-biting and non-crib-biting horses (controls) to an arousal-inducing stimulus were studied. Video-observation of the horses revealed that crib-biting horses spent between 10.4 and 64.7% of their stabling time performing the stereotypy. During the first 2 days...

  15. Impact of riding in a coercively obtained Rollkur posture on welfare and fear of performance horses

    Contributor(s):: Borstel, U. U. von, Duncan, I. J. H., Shoveller, A. K., Merkies, K., Keeling, L. J., Millman, S. T.

    Rollkur, the usually coercively obtained hyperflexion of the horse's neck, is employed as a training method by some dressage riders; however, its use is controversial as it may cause discomfort and adversely affect the horse's welfare. The objectives of this study were to determine: (1) if horses...

  16. Object recognition and generalisation during habituation in horses

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

    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...

  17. 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...

  18. Does feed-back from a nest affect periparturient behaviour, heart rate and circulatory cortisol and oxytocin in gilts?

    Contributor(s):: Damm, B. I., Pedersen, L. J., Marchant-Forde, J. N., Gilbert, C. L.

    To determine the effects of feed-back from a farrowing nest on periparturient behaviour, heart rate and hormones, 20 gilts housed in Schmid pens were permitted to build a nest of peat, straw and branches. Ten gilts then had their nest removed (NR) 10 h after the onset of nest-building and again...

  19. The effects of two different amounts of dietary grain on the digestibility of the diet and behaviour of intensively managed horses

    Contributor(s):: Freire, R., Clegg, H. A., Buckley, P., Friend, M. A., McGreevy, P. D.

    The current experiment examined the effect of switching from a moderate grain diet to a high grain diet, as are typically fed to intensively managed horses, on some behavioural and physiological (oro-caecal transit time [OCTT], digestibility, plasma cortisol concentrations and heart rate)...

  20. Individual differences in aggression and physiology in peri-pubertal breeding gilts

    Contributor(s):: Geverink, N. A., Schouten, W. G. P., Gort, G., Wiegant, V. M.

    Several recent studies on pigs have demonstrated a relationship between the degree of resistance displayed in a so-called "backtest" and a variety of behavioural and physiological responses in piglets and young fattening pigs. However, the discussion about the predictive power of the backtest is...
