  1. Origins of fear of dogs in adults and children: The role of conditioning processes and prior familiarity with dogs

    Contributor(s):: Sharon Doogan, Glyn V. Thomas

    One hundred adults and 30 children completed questionnaires to investigate fear of dogs. Dog fearful adults asked to recall the origins of their fear reported classical conditioning experiences more frequently than vicarious acquisition or informational transmission. Overall, however, there was...

  2. A 'pebble test of anxiety' did not differentiate between Japanese quail divergently selected for stress and fear

    Contributor(s):: Jones, R. B., Marin, R. H., Satterlee, D. G.

    It has been suggested that the time taken by an individually tested domestic chick to begin pecking at pebbles on the floor of a novel arena might be used as a test of fear and anxiety, with low latencies to peck indicating low fear and vice versa, and as a potential selection criterion 'to...

  3. A case series of biting dogs: characteristics of the dogs, their behaviour, and their victims

    Contributor(s):: Guy, N. C., Luescher, U. A., Dohoo, S. E., Spangler, E., Miller, J. B., Dohoo, I. R., Bate, L. A.

    The characteristics of 227 biting dogs, their homes, and their victims were gathered in a detailed telephone survey of general veterinary clientele in the Canadian provinces of New Brunswick, Nova Scotia, and Prince Edward Island in 1996. All of the dogs had bitten either someone living in the...

  4. A comparison of behaviour in test and in everyday life: evidence of three consistent boldness-related personality traits in dogs

    Contributor(s):: Svartberg, K.

    Six specific personality traits - playfulness, chase-proneness, curiosity/fearlessness, sociability, aggressiveness, and distance-playfulness - and a broad boldness dimension have been suggested for dogs in previous studies based on data collected in a standardized behavioural test ("dog...

  5. A note on fear reaction of three different genetic strains of laying hens to a simulated hawk attack in the hen run of a free-range system

    Contributor(s):: Zeltner, E., Hirt, H.

    Hens well adapted to free-range systems should react quickly to avoid an attack by a predator but should also be able to return to the hen run soon after to ensure good use of the outside area. To ascertain if some strains cope better with a frightening event the fear reaction of three different...

  6. A note on measurement of injection aversiveness

    Contributor(s):: Grandin, T., Maxwell, K., Lanier, J.

    The behavior of cattle during an injection of doramectin 1% injectable solution or ivermectin 1% injectable solution in an attempt to measure small differences in aversiveness in 61 red Angus-cross, 2-year-old heifers. Each animal was held in a squeeze chute and given a 9 ml s.c. injection of...

  7. A note on the effects of a commercial tryptophan product on horse reactivity

    Contributor(s):: Malmkvist, J., Christensen, J. W.

    Tryptophan supplements are marketed worldwide as calmatives for fearful or excitable horses, although there are no scientific publications that support the efficiency of tryptophan on horses. Here, we investigate whether a commercial feed additive with tryptophan reduces the reactions of horses...

  8. A note on the relationship between the behavioural response of lactating sows to humans and the survival of their piglets

    Contributor(s):: Hemsworth, P. H., Pedersen, V., Cox, M., Cronin, G. M., Coleman, G. J.

    The objective of this study was to examine the relationships, based on unit averages, between the behavioural responses of lactating sows to humans and the performance of sows in 25 farrowing units at a large commercial farm. The behavioural responses of 25 sows in each farrowing unit were...

  9. A note on the use of behavioural modification to aid clipping ponies

    Contributor(s):: Gough, M. R.

    The aversion of 6 ponies to electric clippers used on their necks were recorded. The ponies were then subjected to the noise of clippers daily while being fed for 2 weeks. One group was subjected to the sight and noise of the clippers, the other group to a tape recording of the clipper noise in...

  10. A note: the effects of human handling on heart girth, behaviour and milk quality in dairy goats

    Contributor(s):: Jackson, K. M. A., Hackett, D.

    Research on cattle, lambs and pigs suggests that when animals do not receive positive physical attention ("gentling") from their stockpersons, they become fearful, stressed, less productive, and less healthy overall. The purpose of this experiment was to examine the effects that positive human...

  11. A preliminary model of human-animal relationships in the zoo

    Contributor(s):: Hosey, G.

    The concept of the human-animal relationship (HAR) is widely used in farm animal research to describe the outcome of the different qualities and quantities of interaction between stockpersons and the animals in their care. Thus, negative, positive or neutral HARs may result from the effect of...

  12. A preliminary study of the effects of individual response to challenge tests and stress induced by humans on learning performance of weaned piglets (Sus scrofa)

    Contributor(s):: Brajon, S., Laforest, J. P., Schmitt, O., Devillers, N.

    This study investigated whether individual behavioural characteristics of piglets and stress induced by experience with humans can influence learning performance. After weaning, piglets received a chronic experience with humans to modulate their emotional state: rough (ROU), gentle (GEN), or...

  13. A prospective study of two self-help CD based desensitization and counter-conditioning programmes with the use of Dog Appeasing Pheromone for the treatment of firework fears in dogs ( Canis familiaris )

    Contributor(s):: Levine, E. D., Ramos, D., Mills, D. S.

    The aims of this study were to evaluate the efficacy of two self-help CD based desensitization and counter-conditioning programmes with the use of Dog Appeasing Pheromone (DAP) for the treatment of firework fears in dogs and to evaluate the training progress and owner compliance. Fifty-four...

  14. A review of the behavioral and neurochemical consequences of early weaning in rodents. (Special Issue: Early Weaning.)

    Contributor(s):: Kikusui, T., Nakamura, K., Mori, Y.

    In mammals, mother-infant bonding is based on the dependence of the infant on the mother for sustenance, i.e., the infant suckles milk, but also involving a need for physical contact. Weaning is one of the most important events that occur in developing animals and the timing of natural weaning is...

  15. A short note on effects of exposure to a novel stimulus (umbrella) on behaviour and percentage of eye-white in cows

    Contributor(s):: Sandem, A. I., Janczak, A. M., Braastad, B. O.

    The present experiment aimed at investigating the sensitivity of "eye-white percentage" as a dynamic indicator of fear in 16 dairy cows and describing the startle response provoked by sudden exposure to an unfamiliar suddenly opened umbrella. Sudden opening of the umbrella 0-2 m in front of cows...

  16. A study of three methods used to assess stockmanship on commercial dairy farms: can these become effective welfare assessment techniques?

    Contributor(s):: Rennie, L. J., Bowell, V. A., Dearing, J. M., Haskell, M. J., Lawrence, A. B.

    The modern dairy industry involves close contact between the stockperson and their animals and thus complex relationships develop between stockperson and cow. This study examines the assessment of stockmanship quality on commercial dairy farms and aims to develop useable protocols for on-farm...

  17. A study on the temperament type of puppies in the animated toy test with regard to their proper socialization and specific behaviour build-up

    Contributor(s):: Stoycheva, I., Uzunova, K., Binev, R., Bivolarski, B., Georgieva, V., Rusenov, A., Slavov, T.

    In order to typify their temperaments and facilitate their training and formation of desired behaviour, 24 7-week-old Pointer, Boxer, and German Shepherd puppies were tested twice in an ethological test. Emphasis was put on behavioural activities such as fear, orientation, purposefulness,...

  18. Affective consciousness: Core emotional feelings in animals and humans

    Contributor(s):: Panksepp, J.

  19. Aggression, fearfulness and coping styles in female pigs

    Contributor(s):: Janczak, A. M., Pedersen, L. J., Bakken, M.

    The coping styles hypothesis states that animals have consistent behavioural and physiological coping responses that can be characterised on a continuum from reactive to proactive. According to this hypothesis, animals can be characterised by consistency in responses across social and non-social...
