  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. 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. Manifestation of neuronal ceroid lipofuscinosis in Australian Merino sheep: observations on altered behaviour and growth

    Contributor(s):: Cronin, G. M., Beganovic, D. F., Sutton, A. L., Palmer, D. J., Thomson, P. C., Tammen, I.

    Neuronal ceroid lipofuscinoses (NCL) is an inherited neurodegenerative disorder in children. Presently there is no effective treatment and the disorder is lethal. NCL occur in a variety of non-human species including sheep, which are recognised as valuable large animal models for NCL. This...

  6. 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...

  7. 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...

  8. 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...

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

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

  10. 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...

  11. Fresh wood reduces tail and ear biting and increases exploratory behaviour in finishing pigs

    Contributor(s):: Telkanranta, H., Bracke, M. B. M., Valros, A.

    Chewing and rooting are high behavioural priorities in pigs. Lack of suitable materials can lead to abnormal behaviours such as tail and ear biting. In commercial farming, slatted floors limit the use of straw, and various point-source objects have therefore been developed. The crucial challenge...

  12. Genetic analysis of the individual pig behaviour in backtests and human approach tests

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

    The most recent development in pig production has focused increasingly on the well-being of the individual pig and animal-friendly housing conditions, i.e. the launch of the group housing of sows in the EU. In this regard, however, standard procedures which may be stressful to the animals and...

  13. A review of the effects of prostaglandins on sexual behavior in boars

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

    Artificial insemination (AI) is the primary method of breeding sows in many countries worldwide. In general, semen for AI is collected using the gloved hand technique from boars trained to mount an artificial sow, although automated collection systems have been developed and are in use on some...

  14. Behaviour epigenetics - the connection between environment, stress and welfare

    Contributor(s):: Jensen, P.

    Epigenetics refers to chemical modifications of DNA, which do not change the base-pair sequence. This involves, for example, methylation of cytosine and different alterations in histone chemistry. Such modifications affect how genes are expressed and can occur as a response to stress, mediated by...

  15. Critical care and survival of fragile animals: the case of Prrxl1 knockout mice

    Contributor(s):: Monteiro, C., Dourado, M., Matos, M., Duarte, I., Lamas, S., Galhardo, V., Lima, D.

    The generation of genetically modified animal models in which a given gene is permanently deleted or overexpressed, sometimes results in fragile phenotypes characterized by high morbidity and premature death. This undesired outcome creates important welfare difficulties and poses a huge...

  16. 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...

  17. 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...

  18. Reliability and validity of a questionnaire survey in canine anxiety research

    Contributor(s):: Tiira, K., Lohi, H.

    Canine behavior can be assessed through behavioral testing or questionnaire surveys. Behavioral tests, often observed by independent experts, can provide objective data, but capture only a short behavioral sequence in a defined situation and are practical only for small study cohorts....

  19. The role of genes, epigenetics and ontogeny in behavioural development

    Contributor(s):: Rodenburg, T. B.

    This review focuses on the role of genes, epigenetics and ontogeny in behavioural development of animals. The behavioural characteristics of an individual are determined by its genes and by its physical and social environment. Not only the individual's early life and current environment are of...

  20. Welfare of farmed musk deer: changes in the biological characteristics of musk deer in farming environments

    Contributor(s):: He, Lan, Li, LinHai, Wang, WenXia, Liu, Gang, Liu, ShuQiang, Liu, WenHua, Hu, DeFu

    Musk deer are an important economic wildlife resource, and long-term over-use has resulted in a sharp population decrease in the wild. Farming of musk deer is important to prevent the shrinking wild population from being hunted for their musk. Musk deer farming has a history of more than 60 years...
