  2. 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...

  3. Attitudes of livestock keepers to breeding strategies - Threats and opportunities for on-farm conservation of the Borana cattle breed

    Contributor(s):: Kerstin K. Zander

    Environmental and market pressures strongly affect cattle breeding in East Africa. While optimising breeding with diverse genetic material can improve income from cattle production, it can also lead to a loss and depletion of valuable animal genetic resources. This study assesses...

  4. Structural variants in genes associated with human Williams-Beuren syndrome underlie stereotypical hypersociability in domestic dogs

    Contributor(s):: Bridgett M. vonHoldt, Emily Shuldiner, Ilana Janowitz Koch, Rebecca Y. Kartzinel, Andrew Hogan, Lauren Brubaker, Shelby Wanser, Daniel Stahler, Clive D. L. Wynne, Elaine A. Ostrander, Janet S. Sinsheimer, Monique A. R. Udell

    Although considerable progress has been made in understanding the genetic basis of morphologic traits (for example, body size and coat color) in dogs and wolves, the genetic basis of their behavioral divergence is poorly understood. An integrative approach using both behavioral and genetic data...

  5. New trends in feline breeding : (Literature review)

    Contributor(s):: Daniela Jasmin Busse

    A responsible breeder will first assure that all the environmental circumstances are given for his cats to live in a healthy, stress free environment, with the substantial care he can provide them. He will have good knowledge of his breeds and their genetic beckground and adjust his breeding...

  6. 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...

  7. Determining the antiquity of dog origins: canine domestication as a model for the consilience between molecular genetics and archaeology

    Contributor(s):: Michelle Jeanette Raisor

    Archaeologists have favored a date of 14,000-15,000 years before present (BP) for canine domestication. However, recent studies of mutations in the mitochondrial DNA sequence by molecular geneticists have implied that dogs were domesticated over 100,000 years ago, which has challenged traditional...

  8. 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...

  9. 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...

  10. 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...

  11. 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...

  12. 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...

  13. 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...

  14. 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...

  15. The major welfare problems of dairy cows in French commercial farms: an epidemiological approach

    Contributor(s):: Roches, A. de B. des, Veissier, I., Coignard, M., Bareille, N., Guatteo, R., Capdeville, J., Gilot-Fromont, E., Mounier, L.

    Animal welfare enhancement requires that problems are reliably identified and ranked in order to prioritise corrective actions. Welfare problems vary with the conditions in which animals are maintained. The objectives were to highlight major welfare problems for dairy cows on farms in France, and...

  16. Genetic diversity of Toxoplasma gondii in animals and humans

    Contributor(s):: L. David Sibley, Asis Khan, James W. Ajioka, Benjamin M. Rosenthal

    Toxoplasma gondii is one of the most widespread parasites of domestic, wild, and companion animals, and it also commonly infects humans. Toxoplasma gondii has a complex life cycle. Sexual development occurs only in the cat gut, while asexual replication occurs in many vertebrate hosts. These...
