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

    Full-text: Available

    | 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. The Dog: A Domestic Wolf to Communicate with Man: The Aggressiveness of the Dog

    | Contributor(s):: Jean-Mane Giffroy

    On the basis of research in archeozoology and molecular genetics, it is established that the wolf is the main ancestor of the dog and that domestication would have occurred some 14,000 or 15,000 years ago, 5,000 years before the domestication of another species. The place or places of the first...

  3. The Dog, the Scientist's best friend: Per Jensen at TEDxNorrkoping

    | Contributor(s):: Per Jensen

    This talk deals with the evolution and development of the dog and the basic aspects of dog behavior and its connection to genetics and comparison with human behaviour. A dog can learn to count, and to distinguish verbs from adjectives. It is clear that dogs understand humans much better than has...

  4. Family Dog Project: history and future of the ethological approach to human-dog interaction

    | Contributor(s):: Abdai, J., Miklosi, A.

    Dogs occupy a specific niche in the human social environment. Some authors argued that dogs' social competence show functional similarities in their components (e.g. attachment, rule following) to that of humans due to their long history living in anthropogenic environment if proper socialisation...

  5. Social group formation and genetic relatedness in reintroduced Asian elephants ( Elephas maximus) in Thailand

    | Contributor(s):: Thitaram, C., Dejchaisri, S., Somgird, C., Angkawanish, T., Brown, J., Phumphuay, R., Chomdech, S., Kangwanpong, D.

    Captive-held elephants were recruited from several parts of Thailand and released as part of a reintroduction project. Wild elephants with a herd matriarch generally contain the same matrilineal line and are genetically related. However, reintroduced elephants are less likely to be related, but...

  6. The backtest in pigs revisited - an analysis of intra-situational behaviour

    | Contributor(s):: Zebunke, M., Repsilber, D., Nurnberg, G., Wittenburg, D., Puppe, B.

    The occurrence of different behavioural phenotypes in animals (regarding temperament and personality) has increasingly attracted the attention of scientists dealing with farm animal breeding, management and welfare. As part of the adaptation repertoire, coping behaviour describes how animals deal...

  7. Human‚Äźdirected social behaviour in dogs shows significant heritability

    | Contributor(s):: Persson, M. E., Roth, L. S. V., Johnsson, M., Wright, D., Jensen, P.

  8. Are farmed salmon more prone to risk than wild salmon? Susceptibility of juvenile farm, hybrid and wild Atlantic salmon Salmo salar L. to an artificial predator

    | Contributor(s):: Solberg, M. F., Zhang, ZhiWei, Glover, K. A.

    Offspring of farmed Atlantic salmon have been documented to display lower survival than the offspring of wild salmon in the wild. It has been suggested that reduced survival of farmed salmon offspring in the wild could, in part, be explained by increased susceptibility to predation through...

  9. Dairy calves' adaptation to group housing with automated feeders

    | Contributor(s):: Fujiwara, M., Rushen, J., Passille, A. M. de

    Group housing of dairy calves with automated milk feeders has likely welfare and labour saving advantages but delays in the calves adapting to the feeding system may reduce these advantages. We examined factors that influence calves' adaptation to the feeders. In Exp. 1, 77 Holstein calves were...

  10. Nutrition for working and service dogs

    | Contributor(s):: Wakshlag, J., Shmalberg, J.

    Conformation, genetics, and behavioral drive are the major determinants of success in canine athletes, although controllable variables, such as training and nutrition, play an important role. The scope and breadth of canine athletic events has expanded dramatically in the past 30 years, but with...

  11. Relationships between young stallions' temperament and their behavioral reactions during standardized veterinary examinations

    | Contributor(s):: Peeters, M., Verwilghen, D., Serteyn, D., Vandenheede, M.

    Horse handling and veterinary examination can induce hazardous stress reactions. Such reactions occur especially in young and less-trained horses, particularly stallions, and make their handling a risk for breeders, grooms, and medical staff. Moreover, these stressful situations will affect the...

  12. 'Bling with bite' - the rise of status and weapon dogs

    | Contributor(s):: Harding, S.

  13. Genetic and environmental influences on individual differences in frequency of play with pets among middle-aged men: a behavioral genetic analysis

    | Contributor(s):: Jacobson, K. C., Hoffman, C. L., Vasilopoulos, T., Kremen, W. S., Panizzon, M. S., Grant, M. D., Lyons, M. J., Xian, H., Franz, C. E.

  14. Environmental enrichment exerts anxiolytic effects in the Indian field mouse (Mus booduga)

    | Contributor(s):: Varman, D. R., Ganapathy, Marimuthu, Rajan, K. E.

  15. Human perceptions of coat color as an indicator of domestic cat personality

    | Contributor(s):: Delgado, M. M., Munera, J. D., Reevy, G. M.

  16. Behavior Genetics of Canine Aggression: Behavioral Phenotyping of Golden Retrievers by Means of an Aggression Test

    | Contributor(s):: van den Berg, L., Schilder, M. B. H., Knol, B. W.

  17. A behaviour test on German Shepherd dogs: heritability of seven different traits

    | Contributor(s):: Ruefenacht, S., Gebhardt-Henrich, S., Miyake, T., Gaillard, C.

    In this study, genetic and non-genetic effects on behavioural traits were estimated, based on records of the field behaviour test of the Swiss German Shepherd Dog breeding club. This standardized test has been applied since 1949 and comprised the following seven traits: self-confidence, nerve...

  18. All a mother's fault? Transmission of stereotypy in striped mice Rhabdomys

    | Contributor(s):: Jones, M., Lierop, M. van, Pillay, N.

    Environmentally induced stereotypy is the most common abnormal behaviour in captive animals. However, not all animals housed in identically impoverished environments develop stereotypy, possibly because of differences in genetic predisposition. To investigate the transmission of stereotypy in...

  19. Effect of male-to-male aggressiveness and feed-restriction during rearing on sexual behaviour and aggressiveness towards females by male domestic fowl

    | Contributor(s):: Millman, S. T., Duncan, I. J. H.

    This experiment was one part of a larger study investigating problems of aggression towards females by male broiler breeder fowl. To investigate causal mechanisms, we were interested in determining (1) if feed-restriction during rearing affects behaviour towards females at sexual maturity and (2)...

  20. Genetic analysis of reactivity to humans in Goettingen minipigs

    | Contributor(s):: Kohn, F., Sharifi, A. R., Simianer, H.

    Goettingen minipigs are laboratory animals with an increasing demand over the last few years. At the moment, Goettingen minipigs are not selected for a low reactivity to humans and this trait is not included in the breeding programme. However, it is obvious that there is a need for genetically...
