  1. 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....

  2. Reactions of calves to handling depend on housing condition and previous experience with humans

    Contributor(s):: Lensink, B. J., Raussi, S., Boivin, X., Pyykkonen, M., Veissier, I.

    This study investigated the influence of stockperson's behaviour and housing conditions on calves' behavioural reactions to people, and behavioural and physiological reactions to handling and short transport. Sixty-four Finnish Ayrshire male calves were used; half of them were housed in...

  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. 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...

  5. A note on the effect of gestation housing environment on approach test measures in gilts

    Contributor(s):: Marchant-Forde, J. N., Bradshaw, R. H., Marchant-Forde, R. M., Broom, D. M.

    Systems' welfare evaluation, including behavioural testing, is becoming increasingly popular in farm animal assurance schemes. The aims of this study were to investigate whether fairly short-term exposure to gestation housing systems, which varied in physical, environmental and human-input...

  6. Responses of dairy cows and calves to each other's vocalisations after early separation

    Contributor(s):: Marchant-Forde, J. N., Marchant-Forde, R. M., Weary, D. M.

    Current commercial dairy practice involves the removal of the calf from the dam within the first day of life. Both vocalize after separation. The aim of this study was to determine if cows and calves respond to each other's calls after separation and whether they could distinguish their own...

  7. Dogs can discriminate barks from different situations

    Contributor(s):: Maros, K., Pongracz, P., Bardos, G., Molnar, C., Farago, T., Miklosi, A.

    We investigated if dogs can discriminate barks of another individual recorded in two markedly different situations: (a) when a stranger entered the property where the dog lived, and (b) when the dog was tethered to a tree and left alone. We used a habituation-dishabituation paradigm for testing...

  8. 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...

  9. Assessment of equine temperament by a questionnaire survey to caretakers and evaluation of its reliability by simultaneous behavior test

    Contributor(s):: Momozawa, Y., Ono, T., Sato, F., Kikusui, T., Takeuchi, Y., Mori, Y., Kusunose, R.

    We carried out a questionnaire survey of the caretakers, using 86 riding horses kept in the Equestrian Park, Tokyo (Japan Racing Association). The questionnaire survey used a 5-point scale and a 3-point scale to assess several caretakers' impressions of each horse's temperament, on the basis of...

  10. The effect of a feeding stress-test on the behaviour and heart rate variability of control and crib-biting horses (with or without inhibition)

    Contributor(s):: Nagy, K., Bodo, G., Bardos, G., Harnos, A., Kabai, P.

    Crib-biting is a form of oral stereotypy affecting 4-5% of horses. Once fixed, crib-biting is difficult to eliminate by behaviour therapy, however, its performance can be inhibited by collar or surgery treatment (modified Forssell's procedure). Although surgical intervention is widespread, the...

  11. Feed barrier design affects behaviour and physiology in goats

    Contributor(s):: Nordmann, E., Keil, N. M., Schmied-Wagner, C., Graml, C., Langbein, J., Aschwanden, J., Hof, J. von, Maschat, K., Palme, R., Waiblinger, S.

    Among other things, feed barrier design for goats can differ with regard to ease of leaving, backward view, and presence of physical separation. The aim of our study was to investigate whether the type of feed barrier influences agonistic behaviour and stress. The study involved 55 adult...

  12. Agonistic interactions and physiological reactions of top- and bottom-ranking pigs confronted with a familiar and an unfamiliar group: preliminary results

    Contributor(s):: Otten, W., Puppe, B., Stabenow, B., Kanitz, E., Schon, P. C., Brussow, K. P., Nurnberg, G.

    Four trials were carried out, where in each trial during a selection test 2 groups of growing pigs (12 weeks old) with 9 animals each were randomly formed. After a week, the top (TR) and bottom (BR) ranking pig from each group was isolated and kept under single housing conditions. At the age of...

  13. Effects of feed-back from the nest on maternal responsiveness and postural changes in primiparous sows during the first 24 h after farrowing onset

    Contributor(s):: Pedersen, L. J., Damm, B. I., Marchant-Forde, J. N., Jensen, K. H.

    In order to elucidate whether feed-back from a farrowing nest affects the sows' activity level and responsiveness to piglets during the first 24 h after the onset of parturition, 18 primiparous Landrace x Yorkshire sows were given the opportunity to build a farrowing nest of peat, straw and...

  14. Effects of mirror-image exposure on heart rate and movement of isolated heifers

    Contributor(s):: Piller, C. A. K., Stookey, J. M., Watts, J. M.

    Characteristics of a fear response in cattle include an increased heart rate, and signs of agitation. Cattle show this response when visually isolated from herdmates. Two trials were conducted to determine whether exposure to a mirror reduces the stress of social isolation of 41 heifers confined...

  15. Identification of potential physiological and behavioral indicators of postoperative pain in horses after exploratory celiotomy for colic

    Contributor(s):: Pritchett, L. C., Ulibarri, C., Roberts, M. C., Schneider, R. K., Sellon, D. C.

    Physiological and behavioral parameters were determined in 27 horses to identify potential indicators of postoperative pain following exploratory celiotomy for colic. Experimental groups were 10 horses that received no treatment (Control), 10 horses anesthetized for a non-painful procedure...

  16. The effect of time left alone at home on dog welfare

    Contributor(s):: Rehn, T., Keeling, L. J.

    The aim of this study was to investigate the effect of time left alone on dog behaviour and cardiac activity. Twelve privately owned dogs, with no history of separation related behaviour problems, were video-recorded on three different occasions when left alone in their home environment. The...

  17. Behavioural and physiological responses of horses to initial training: the comparison between pastured versus stalled horses

    Contributor(s):: Rivera, E., Benjamin, S., Nielsen, B., Shelle, J., Zanella, A. J.

    Horses kept in stalls are deprived of opportunities for social interactions, and the performance of natural behaviour is limited. Inadequate environmental conditions may compromise behavioural development. Initial training is a complex process and it is likely that the responses of horses may be...

  18. Both energy content and bulk of food affect stereotypic behaviour, heart rate and feeding motivation of female pigs

    Contributor(s):: Robert, S., Rushen, J., Farmer, C.

    The effect of high-fibre diets on feeding motivation and feeding-related stereotypic behaviour was examined in gilts. Forty gilts were fed on a concentrate diet (CONC) or high-fibre diets balanced for energy (WHEAT, wheat bran and maize cobs or OAT, oat hulls and oat) or with a lower energy...

  19. Effects of repeated stress during pregnancy in ewes on the behavioural and physiological responses to stressful events and birth weight of their offspring

    Contributor(s):: Roussel, S., Hemsworth, P. H., Boissy, A., Duvaux-Ponter, C.

    Stressors are frequently encountered during the pregnancies of farm animals. However, very few studies have investigated the effects of repeated stress in pregnant females on their offspring. Forty-eight ewes at 2.5 months of pregnancy were selected for their high or low cortisol response to...

  20. Human contact and the effects of acute stress on cows at milking

    Contributor(s):: Rushen, J., Munksgaard, L., Marnet, P. G., Passille, A. M. de

    We examined the effects of novelty/isolation stress on cows at milking and whether human contact reduced the stress. Holstein cows (n=18) were observed during three experimental milkings following a balanced order: (1) control (C)-milked in usual place; (2) novelty/isolation stress (S)-milked...
