  1. Identification and development of measures suitable as potential breeding traits regarding dairy cows' reactivity towards humans

    Contributor(s):: Ebinghaus, A., Ivemeyer, S., Rupp, J., Knierim, U.

    Behavioural indicators of the human-animal relationship (HAR) are predominantly used in animal welfare science. However, the reactivity of dairy cows - as part of the HAR - is also of interest in the context of dairy breeding, due to its estimated moderate heritability. The avoidance distance...

  2. Pets and happiness: examining the association between pet ownership and wellbeing

    Contributor(s):: Bao, K. J., Schreer, G.

    Are pets associated with happiness in their owners? Some research has demonstrated positive connections between pets and the physical health of their owners, and more recently, research has shown the beneficial effects of pets on the negative aspects of mental health as well. However, much less...

  3. Training success in group-housed long-tailed macaques ( Macaca fascicularis) is better explained by personality than by social rank

    Contributor(s):: Wergard, E. M., Westlund, K., Spangberg, M., Fredlund, H., Forkman, B.

    Using training to prepare laboratory animals for biomedical research is one important behavior management task. With increased knowledge about factors influencing training success, training programs may be optimized, resulting in a refinement of primate husbandry. Even when animals are trained...

  4. Relationship between behavioural tests and agonistic interactions at different age levels in pigs

    Contributor(s):: Scheffler, K., Stamer, E., Traulsen, I., Krieter, J.

    Fighting among pigs is a normal behavioural pattern to establish a stable rank order. Enhanced aggressive behaviour in pigs in groups lead to increasing stress and injuries especially in mixing situations used as a common procedure in modern pig production systems. In such systems, it is usually...

  5. Relationships between personality of human-dog dyads and performances in working tasks

    Contributor(s):: Hoummady, S., Peron, F., Grandjean, D., Clero, D., Bernard, B., Titeux, E., Desquilbet, L., Gilbert, C.

    Improving operational performances of working dog-human dyads is receiving more and more attention. Despite this interest, the associations between human personality, dog personality, dog-human personality matching and dyad performances have rarely been addressed. This study explores the links...

  6. Long-term effects of straw blocks in pens with finishing pigs and the interaction with boar type

    Contributor(s):: Bulens, A., Beirendonck, S. van, Thielen, J. van, Buys, N., Driessen, B.

    This study verified the effect of straw blocks on the behavior and growth of finishing pigs and possible interactions with the genetic background (boar type). A total of 359 finishing pigs, which were offspring from different boar types, were housed in gender-mixed pens with slatted floors. Half...

  7. Preliminary investigation of food guarding behavior in shelter dogs in the United States

    Contributor(s):: Mohan-Gibbons, H., Weiss, E., Slater, M.

    A survey given to animal shelters across the US reported food bowl guarding as one of the most common reasons for euthanasia and only 34% attempted to modify this guarding behavior. This study identified 96 dogs that guarded their food bowl during an assessment, and then placed them into a home...

  8. Genetic study of stress assessed with infrared thermography during dressage competitions in the Pura Raza Espanol horse

    Contributor(s):: Sanchez, M. J., Bartolome, E., Valera, M.

    Despite the fact that physiological parameters in dressage are important because of their close connection to human-horse accidents, performance and welfare, these parameters are only rarely included in horse breeding programs. In Spain, the Pura Raza Espanol horse (PRE) Breeding Program focuses...

  9. Neonatal piglets are able to differentiate more productive from less productive teats

    Contributor(s):: Devillers, N., Giraud, D., Farmer, C.

    A previously-validated method to induce variation in milk production between teats of the same udder that is not related to the ante-posterior location of the teat was used. In the first lactation, over half of the sows' teats (teats 1, 2, 5, 6, and 7 from 1 side of the udder, and teats 3, 4, and...

  10. The social network structure of a dynamic group of dairy cows: from individual to group level patterns

    Contributor(s):: Boyland, N. K., Mlynski, D. T., James, R., Brent, L. J. N., Croft, D. P.

    Social relationships have been shown to significantly impact individual and group success in wild animal populations, but are largely ignored in farm animal management. There are substantial gaps in our knowledge of how farm animals respond to their social environment, which varies greatly...

  11. The canine cuteness effect: owner-perceived cuteness as a predictor of human-dog relationship quality

    Contributor(s):: Thorn, P., Howell, T. J., Brown, C., Bennett, P. C.

    The modern domestic dog's primary function is as a human companion. A strong human-dog relationship may be beneficial to both parties but not all relationships are successful. There is currently no consensus on why some dog-owner relationships flourish and others fail, but relationship quality...

  12. The anthrozoomorphic identity: furry fandom members' connections to nonhuman animals

    Contributor(s):: Roberts, S. E., Plante, C. N., Gerbasi, K. C., Reysen, S.

    We examined furry fandom members' anthrozoomorphic identity by investigating this subculture's relationship with nonhuman animals. Using exploratory and confirmatory factor analyses and two largescale Internet and convention-based studies of furries, we developed (study 1; n=4,338) and replicated...

  13. Heritability of behavioural traits in domestic dogs: a meta-analysis

    Contributor(s):: Hradecka, L., Bartos, L., Svobodova, I., Sales, J.

    Reviews summarizing the literature on heritability of behavioural traits in dogs have been published repeatedly over the last four decades. The conclusions of these reviews vary to some extent. We applied meta-analysis and re-evaluated the literature available collecting 48 references dealing...

  14. Investigating the role of coat colour, age, sex, and breed on outcomes for dogs at two animal shelters in the United States

    Contributor(s):: Svoboda, H. J., Hoffman, C. L.

    The popular press frequently reports that coat colour bias negatively impacts shelter adoption rates for black domestic dogs. This phenomenon, commonly called 'black dog syndrome' (BDS), reportedly increases the likelihood of euthanasia for black dogs and negatively affects the length of black...

  15. Object Neophilia in Domestic Purebred Dogs

    Contributor(s):: Lydia Kniowski

    Neophilia is defined as a preference for novelty. This characteristic has been described in a variety of animal species, and may have been a contributing factor in the domestication of dogs. This study tested three purebred dog breeds for neophilia with inanimate objects. Observations of...

  16. Are emotionally attached companion animal caregivers conscientious and neurotic? factors that affect the human-companion animal relationship

    Contributor(s):: Reevy, G. M., Delgado, M. M.

    Few studies have examined how personality traits may be related to the amounts and types of attachments humans have toward companion animals (pets). In this study, 1,098 companion animal guardians (owners) completed a survey that included the Big Five Inventory, the Lexington Attachment to Pets...

  17. Breed differences in everyday behaviour of dogs

    Contributor(s):: Asp, H. E., Fikse, W. F., Nilsson, K., Strandberg, E.

    The domestication of the dog and the ensuing breed creation has resulted in a plethora of dog breeds that differ not only in morphology but also in terms of behaviour. In addition, a majority of the dogs today are no longer utilized for their working ability, but are mainly kept as companion...

  18. Speed of dog adoption: impact of online photo traits

    Contributor(s):: Lampe, R., Witte, T. H.

    The Internet has radically changed how dogs are advertised for adoption in the United States.
