  1. 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...

  2. The effects of blindfolding on behavior and heart rate in beef cattle during restraint

    Contributor(s):: Mitchell, K. D., Stookey, J. M., Laturnas, D. K., Watts, J. M., Haley, D. B., Huyde, T.

    Use of a blindfold or hood during handling and restraint has been suggested for many wild and captive animals. Two experiments were conducted to determine the effects of blindfolds on beef cattle during restraint. In Experiment 1, 60 beef heifers, naive to the restraint facility, were randomly...

  3. The effects of housing on heart rate of gestating sows during specific behaviours

    Contributor(s):: Marchant, J. N., Rudd, A. R., Broom, D. M.

    The heart rates of 21 sows in 3 different dry sow housing systems (7 sows per housing system) were measured during feeding, drinking, rooting and lying with eyes open. Measurements were made on sows kept in: a large group of 37 with an electronic sow feeder; small groups of 5, with individual...

  4. The propensity of cattle to vocalise during handling and isolation is affected by phenotype

    Contributor(s):: Watts, J. M., Stookey, J. M.

    We investigated whether phenotype affects vocal and behavioural responses of newly-weaned beef calves during handling situations, and whether vocal response differs between two types of handling situation. The phenotypic characteristic chosen was hair colour. Steers were classified into four...

  5. 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...

  6. The use of a mirror reduces isolation stress in horses being transported by trailer

    Contributor(s):: Kay, R., Hall, C.

    Horse trailers are a common form of transportation for horses and ponies and often require the animal to travel alone or with a single companion. The current study investigated the effect of transporting horses alone, in company or with an acrylic safety mirror (measuring 81 cm x 61.5 cm) that...

  7. 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...

  8. Vocalisations of the adult female domestic pig during a standard human approach test and their relationships with behavioural and heart rate measures

    Contributor(s):: Marchant, J. N., Whittaker, X., Broom, D. M.

    Vocal communication in the domestic pig is generally not well documented. The aim of this experiment was to categorise and ascribe the function of the vocalisations of 67 Large White x Landrace gilts during a standard human approach test. At testing, each group of 3-5 gilts was moved to a...

  9. A review of pain assessment techniques and pharmacological approaches to pain relief after bovine castration: practical implications for cattle production within the United States. (Special Issue: Pain in farm animals.)

    Contributor(s):: Coetzee, J. F.

    Castration of male calves destined for beef production is a common livestock management practice in the United States amounting to approximately 7 million procedures per year. Recently there has been renewed interest in identifying methods to reduce pain associated with dehorning and castration....

  10. An evaluation of the physiological affects of anticipation, activity arousal and recovery in sprinting Greyhounds

    Contributor(s):: Gillette, R. L., Angle, T. C., Sanders, J. S., DeGraves, F. J.

    This study was designed to separate the physically induced effects of activity from the psychologically induced effects of anticipation of activity. The purpose of this study was to determine if a psychological experience (i.e., activity anticipation) would cause a significant physiological...

  11. 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...

  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. Do pigs distinguish between situations of different emotional valences during anticipation?

    Contributor(s):: Imfeld-Mueller, S., Wezemael, L. van, Stauffacher, M., Gygax, L., Hillmann, E.

    An animal's welfare is strongly affected by its emotional state. Thus, many recent studies have focused on measuring the emotional states and responses of animals. However, there is still a lack of knowledge on assessing positive emotions, although it is widely accepted that positive emotions are...

  14. 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...

  15. Effects of handling on behaviour and heart rate in Konik horses: comparison of stable and forest reared youngstock

    Contributor(s):: Jezierski, T., Jaworski, Z., Gorecka, A.

    30 foals and young Konik horses born in 3 consecutive years and reared up to weaning, either in a forest reserve (R) or conventional stable (S), were compared with respect to behavioural reactions and heart rate (HR) during handling manipulations. The foals were randomly allocated within sex and...

  16. Emotional reactions to learning in cattle

    Contributor(s):: Hagen, K., Broom, D. M.

    It has been suggested that during instrumental learning, animals are likely to react emotionally to the reinforcer. They may in addition react emotionally to their own achievements. These reactions are of interest with regard to the animals' capacity for self-awareness. Therefore, we devised a...

  17. 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...

  18. 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...

  19. Individual differences in behaviour, physiology and pathology in breeding gilts housed in groups or stalls

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

    A number of studies in young pigs have demonstrated a relation between a variety of behavioural and physiological features and the degree of resistance displayed early in life in a so-called "backtest". The current study aimed at investigating the relation between the backtest response and the...

  20. 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...
