Using 480h of observational behavior data, three personality traits were determined based...

  6. A novel approach to systematically compare behavioural patterns between and within groups of horses

    Contributor(s):: Ellis, Andrea D., Stephenson, Melissa, Preece, Michaela, Harris, Pat

    This study piloted a multiple aspect approach to assess differences or changes in equine behaviour, using physiological (heart rates – HR, salivary cortisol – SC) and behavioural measures in various routine (feed-time, riding, turning out) and test situations (novel situation tests NS: 2×...

  7. Behavioural and physiological responses of heifer calves to acute stressors: Long-term consistency and relationship with adult reactivity to milking

    Contributor(s):: Van Reenen, Cornelis G., Van der Werf, Jozef T. N., O’Connell, Niamh E., Heutinck, Leonie F. M., Spoolder, Hans A. M., Jones, R. Bryan, Koolhaas, Jaap M., Blokhuis, Harry J.

    The present study investigated the long-term consistency of individual differences in dairy cattles’ responses in tests of behavioural and hypothalamo–pituitary–adrenocortical (HPA) axis reactivity, as well as the relationship between responsiveness in behavioural tests and the reaction to first...

  8. Behavioral differences among breeds of domestic dogs (Canis lupus familiaris): Current status of the science

    Contributor(s):: Mehrkam, Lindsay R., Wynne, Clive D. L.

    In both popular media and scientific literature, it is commonly stated that breeds of dogs differ behaviorally in substantial, consistent and predictable ways. Since the mid-twentieth century, scientists have asked whether meaningful behavioral differences exist between breeds of dogs. Today,...

  9. Age over experience: Consistency of aggression and mounting behaviour in male and female pigs

    Contributor(s):: Clark, Corinna C. A., D’Eath, Richard B.

    Excessive aggression between pigs at mixing is a welfare and production issue resulting in stress, injuries and economic losses. If it can be demonstrated that aggression is a consistent behaviour trait, it might provide a means to reduce these losses. To test for consistency of aggressiveness,...

  10. Who's afraid of the big bad glove? Testing for fear and its correlates in mink

    Contributor(s):: Meagher, Rebecca K., Duncan, Ian, Bechard, Allison, Mason, Georgia J.

    Fear in farm animals is a welfare and economic concern. For Scandinavian mink, the “stick test” is common for assessing fearfulness: a spatula is inserted into the cage and minks’ immediate responses are noted. However, on Ontario farms, fearfulness in the stick test was very rare and aggressive...

  11. Validation of an algorithm for real-time measurement of sheep activity in confinement by recording movement within a commercial weighing crate

    Contributor(s):: Horton, Brian J., Miller, Dale R.

    This study reports a method of measuring sheep activity in confinement based on recording movement of sheep during weighing. The aim was to show that an algorithm to analyse continuous weight records could be used to measure activity quickly and efficiently using commercial weighing equipment and...

  12. Selection for temperament in sheep: Domain-general and context-specific traits

    Contributor(s):: Beausoleil, Ngaio J., Blache, Dominique, Stafford, Kevin J., Mellor, David J., Noble, Alasdair D. L.

    Sheep at the University of Western Australia have been selectively bred for behavioral responses to isolation and human presence in an arena test, resulting in the creation of two divergent lines: More Active (MA) and Less Active (LA). The aim of this study was to determine whether selection was...

  13. Reducing the incidence of net cage biting and the expression of escape-related behaviors in Atlantic cod (Gadus morhua) with feeding and cage enrichment

    Contributor(s):: Zimmermann, Emily W., Purchase, Craig F., Fleming, Ian A.

    The escape of fish from aquaculture is a persistent economic problem for farmers as well as an environmental problem that threatens wild fish population as a consequence of potential negative ecological and genetic interactions. Farmed Atlantic cod (Gadus morhua) cause significant damage by...

  14. Reactivity to humans and fearfulness tests: Field validation in Polish Cold Blood Horses

    Contributor(s):: Górecka-Bruzda, Aleksandra, Jastrzębska, Ewa, Sosnowska, Zofia, Jaworski, Zbigniew, Jezierski, Tadeusz, Chruszczewski, Michał H.

    The aim of the present paper was to examine in field conditions the feasibility of the experimentally developed behavioural tests for assessment of two temperamental traits of cold blood horses: fearfulness and reactivity to humans. The predictive, convergent and discriminant validity of the...
