  1. Shyness-boldness predicts performance in working dogs

    Contributor(s):: Svartberg, K.

    This study investigates if there are relationships between personality and performance of dogs (Canis familiaris) in working dog trials. Data from 2655 dogs of the two breeds German Shepherd dog (GSD) and Belgian Tervuren (BT) in Sweden obtained between 1989 and 1997 were used. The breeds were...

  2. The relationships between temperament during routine handling tasks, weight gain and facial hair whorl position in frequently handled beef cattle

    Contributor(s):: Olmos, G., Turner, S. P.

    A relationship has been described between facial hair whorl position and temperament in infrequently handled beef cattle when both traits were measured on categorical scales. Hair whorl position has also been found to relate to daily weight gain in dairy heifers. Using both a categorical scale...

  3. The spontaneous qualitative assessment of behavioural expressions in pigs: first explorations of a novel methodology for integrative animal welfare measurement

    Contributor(s):: Wemelsfelder, F., Hunter, E. A., Mendl, M. T., Lawrence, A. B.

    This study investigated the extent to which 18 naive observers showed agreement when given the opportunity to qualitatively describe, independently and in their own words, the behavioural expressions of 20 individual growing pigs. Pigs were brought singly into a test pen and given the opportunity...

  4. Twenty-four hour activity budgets and patterns of behavior in captive ocelots ( Leopardus pardalis )

    Contributor(s):: Weller, S. H., Bennett, C. L.

    Activity budgets of captive ocelots (Leopardus pardalis) were assessed from over 547 h of observational data obtained from six ocelots; two females at the Dallas Zoo (Dallas, TX), two females at the Caldwell Zoo (Tyler, TX) and a male and female at the Fossil Rim Wildlife Centre (Glen Rose, TX)....

  5. Behavioral variation among cloned pigs

    Contributor(s):: Archer, G. S., Friend, T. H., Piedrahita, J., Nevill, C. H., Walker, S.

  6. Consistency of aggressive feeding behaviour in dairy cows

    Contributor(s):: Gibbons, J. M., Lawrence, A. B., Haskell, M. J.

    This study tests the two main characteristics of a temperament trait, consistency across time and consistency across situations. The temperament trait of interest was aggressiveness during feeding in dairy cattle. In this study, we focused on whether it is possible to infer a trait of...

  7. Does environmental enrichment affect the behaviour of fish commonly used in laboratory work? (Special Issue: Animal suffering and welfare.)

    Contributor(s):: Brydges, N. M., Braithwaite, V. A.

    Housing conditions can have significant effects on the behaviour and physiology of captive animals. Enriching barren environments, for example by providing structural complexity or companionship, are generally considered beneficial as they can decrease the occurrence of abnormal behaviours and...

  8. Estimating genetic variability in temperamental traits in German Angus and Simmental cattle

    Contributor(s):: Gauly, M., Mathiak, H., Hoffmann, K., Kraus, M., Erhardt, G.

    Behavioural traits related to temperament were studied, and the genetic variability estimated in German Angus (Aberdeen Angus x German dual purpose breeds) and Simmental cattle. Temperament was defined as the behavioural response of the animal to handling. Five progeny groups of both breeds...

  9. Reliability of temperament tests on finishing pigs in group-housing and comparison to social tests

    Contributor(s):: Brown, J. A., Dewey, C., Delange, C. F. M., Mandell, I. B., Purslow, P. P., Robinson, J. A., Squires, E. J., Widowski, T. M.

    If variation in behaviour is consistent within individuals and reliably associated with relevant welfare measures, this variation could aid in genetic selection, or development of management schemes designed to improve welfare. In this study, we focused on temperament tests in group-housed...

  10. 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...

  11. Temperament and sexual experience affect female sexual behaviour in sheep

    Contributor(s):: Gelez, H., Lindsay, D. R., Blache, D., Martin, G. B., Fabre-Nys, C.

    Our aim was to study the effect of temperament and sexual experience on female sexual behaviour. We used ewes from a flock that had been genetically selected for 'calm' or 'nervous' temperament, in which oestrus was synchronized by a 14-day treatment with intravaginal progesterone sponge. Using...

  12. The effect of early human contact and the separation method from the dam on responses of beef calves to humans

    Contributor(s):: Boivin, X., Gilard, F., Egal, D.

    The objectives of this experiment were to evaluate the effect of early human contact and of the separation method from the dam on the future relationships of calves with humans, and to investigate the relationship between dam responses and calf responses. Thirty-three Salers calves aged 2-4 days...

  14. Temperament assessment as welfare indicator in a dog training unit

    Contributor(s):: Mitranescu, E., Furnaris, F., Tudor, L., Lataretu, A., Giurca, C.

    Temperament represents the genetic predisposition of an individual to manifest certain behaviours. In a dog training unit from the centre of Romania, the temperament of 20 dogs was assessed. Dogs were divided into two subgroups: Subgroup A, consisting of 10 females from breeding stock and...

  15. Diferencias individuales en los perros domésticos (Canis familiaris): Revisión de las evaluaciones conductales

    Contributor(s):: Jakovcevic, Adriana, Bentosela, Mariana

  16. Certifying temperament

    Contributor(s):: Stockman, M. J.

  17. Relationship between blood pressure and stress-prone temperament in dogs

    Contributor(s):: Vincent, I. C., Michell, A. R.

    As part of an assessment of stress during the training of guide dogs for the blind, blood pressures were monitored in their main breeds. A population of 227 Labradors, between 9 and 24 months of age, had indirect arterial blood pressures measured and means taken of 5 readings. They were ranked...

  18. Genetic control of dairy cattle behavior

    Contributor(s):: Schutz, M. M., Pajor, E. A.

    Past efforts to understand the genetics of behaviour in cattle, and livestock in general, have emphasized changes related to the domestication process. Especially in intensive systems, domestic cattle may not express the full range of innate behaviour when they are provided with food, shelter,...

  19. Important behavioral traits for predicting guide dog qualification

    Contributor(s):: Arata, S., Momozawa, Y., Takeuchi, Y., Mori, Y.

    Guide dogs for the blind help blind people physically and mentally in their daily lives. Their qualifications are based on health, working performance and temperament; approximately 70% of dogs that fail to qualify are disqualified for behavioral reasons. In order to achieve early prediction of...
