  3. Effects of weight, litter size and parity of mother on the behaviour of the puppy and the adult dog

    Contributor(s):: Wilsson, E., Sundgren, P. E.

    During 1978-83, behaviour tests were carried out on 867 German Shepherd puppies at 8 weeks of age and again at 450-600 days of age. Body weight was recorded every 10 days to 50 days of age. Litter size and parity of the dam were also recorded. Puppy weight decreased with increasing litter size (r...

  4. Facial hair whorl position and temperament in cattle

    Contributor(s):: Randle, H. D.

    57 Bos taurus cattle were scored on 19 measures of personality, 14 of which related to temperament. Measures included response to a novel object, cognitive problem solving ability and response to a familiar human, an unfamiliar man and men in general. Individual animals were classed as having a...

  5. Selection against stereotypic behaviour may have contradictory consequences for the welfare of farm mink ( Mustela vison )

    Contributor(s):: Svendsen, P. M., Hansen, B. K., Malmkvist, J., Hansen, S. W., Palme, R., Jeppesen, L. L.

    The present study aimed to examine if divergent selection for stereotypic behaviour in mink influences the welfare of the animals. Two breeding lines were used, a high stereotyping line (HSL, N=139) and a low stereotyping line (LSL, N=132). Their welfare was assessed on the basis of...

  6. A review of some factors affecting the expression of libido in beef cattle, and individual bull and herd fertility

    Contributor(s):: Petherick, J. C.

    This paper examines some of the factors that affect the expression of libido in beef cattle, focusing on the male and the free-ranging situation. The ways in which bull libido is assessed and the relationship between libido test results and fertility are discussed. Genetics play a role in...

  7. Assessment of equine temperament questionnaire by comparing factor structure between two separate surveys

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

    To establish a method for assessing equine temperament by use of a questionnaire, we carried out two surveys. The subject animals were all thoroughbreds maintained at the same farm. Respondents were the primary caretaker and two colleagues working with each horse. Factor analysis was performed on...

  8. Consistency in avoidance of humans by individual red deer

    Contributor(s):: Pollard, J. C., Littlejohn, R. P.

    Four groups of red deer, housed inside, were given 3 tests per day for 6 days. All tests began with a person standing at the front wall of the pen for 1 min, the person remained stationary for a further minute (A tests), walked to the centre of the pen and stood for 1 min (B tests), or walked to...

  9. Consistency of flight speed and its correlation to productivity and to personality in Bos taurus beef cattle

    Contributor(s):: Muller, R., Keyserlingk, M. A. G. von

    Flight speed (FS) has been used as a measure of temperament and is correlated with weight gain in Bos indicus cattle. However, no work to date has investigated this relationship in Bos taurus cattle and, more importantly, there have been no attempts to understand the individual differences in...

  10. Describing categories of temperament in potential guide dogs for the blind

    Contributor(s):: Murphy, J. A.

    Trainers at the Royal Guide Dogs Associations of Australia (RGDAA) assess 12-month-old potential guide dogs for 20 categories of temperament after walking and observing each dog over 5 days in increasingly complex environments. The way trainers interpret these temperament categories from the...

  11. Differences in motor laterality between breeds of performance horse

    Contributor(s):: McGreevy, P. D., Thomson, P. C.

    This study examined the relationship between motor laterality in horses bred for different types of work and therefore different temperaments. Foreleg preference during grazing was measured in three populations of domestic horse, Thoroughbreds (TB, bred to race at the gallop), Standardbreds (SB,...

  12. Differences in temperament traits between crib-biting and control horses

    Contributor(s):: Nagy, K., Bodo, G., Bardos, G., Banszky, N., Kabai, P.

    Recent studies have suggested that crib-biting in horses is associated with diminished capacity of learning or coping with stress. Such findings raise the question whether trainability, which is fundamentally important in practice, could also be affected by stereotypic behaviour. Trainability of...

  13. Evaluation and comparison of four methods of ranking horses based on reactivity

    Contributor(s):: McCall, C. A., Hall, S., McElhenney, W. H., Cummins, K. A.

    Four methods of ranking horses on reactivity were evaluated and compared: isolation from conspecifics, presentation of a static novel stimulus, traversing a novel stimulus in a runway (isolation, novel stimulus and runway tests, respectively) and assigning subjective emotionality scores. In all...

  14. Quantification of temperament in weaned deer calves of two genotypes ( Cervus elaphus and Cervus elaphus x Elaphurus davidianus hybrids)

    Contributor(s):: Pollard, J. C., Littlejohn, R. P., Webster, J. R.

    In the 1st of 2 experiments, 30 [male] red deer (Cervus elaphus), weaned at 3-4 months of age, were kept in pens indoors in groups of 15. Behaviour was recorded during the following tests which were carried out from days 1-27 after weaning: time taken to feed in the presence of a human; time...

  15. Relationship of three measures of behavior to milk production

    Contributor(s):: Purcell, D., Arave, C. W., Walters, J. L.

    Nine commercial herds were observed on three separate occasions for flight distance, i.e., how close a human can come before a stationary cow moves away, and approach distance, i.e., how close a cow will come to a stationary human. Herdsmen from each herd scored their cows on parlour behaviour...

  16. The effect of some common management practices on the ease of handling of dairy cows

    Contributor(s):: Lewis, N. J., Hurnik, J. F.

    Ease of handling (halter placement, leading, entering the squeeze, entering the headgate and exiting the squeeze) of 40 multiparous and 40 primiparous dairy cows, housed in tie stalls and milked in a herringbone parlour, was scored and analysed for effects related to recent (6 months) management...

    Contributor(s):: McCune, S.

    37 kittens, the offspring of an 'unfriendly' or 'friendly' father, were handled between 2 and 12 weeks of age (socialised) or received no handling (unsocialised); the response to a familiar person, a stranger and a novel object were tested when the kittens were 1 year old. Offspring from the...

    Contributor(s):: Kilgour, R. J.

    At 6, 12 and 20 months of age, the behaviour of Australian Merino sheep selected for lamb-rearing ability (31 rams and 29 ewes, fertility flock) was compared with that of unselected sheep (34 rams and 48 ewes) in an arena test. The test consisted of an approach/avoidance test where a sheep was...

    Contributor(s):: Grandin, T., Deesing, M. J., Struthers, J. J., Swinker, A. M.

    1500 cattle weighing 180-360 kg were temperament rated on a 4-point scale to determine whether hair whorl position on the forehead is related to a calm temperament. 72% of the cattle were European x British breed crosses and 28% were zebu x dairy breed crosses from Mexico. Cattle with a round...
