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

    Contributor(s):: Rodenburg, T. Bas

    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...

  2. Icelandic horses with the Silver coat colour show altered behaviour in a fear reaction test

    Contributor(s):: Brunberg, Emma, Gille, Sanna, Mikko, Sofia, Lindgren, Gabriella, Keeling, Linda J.

    The colour of a horse's coat has long been discussed to reflect its temperament. One opinion is that Silver coloured horses are nervous, difficult to handle and react more strongly to different fear stimuli. The objective with the present study was to investigate if mutations associated with the...

  3. Behaviour epigenetics – The connection between environment, stress and welfare

    Contributor(s):: Jensen, Per

    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...

  4. Genetic and non-genetic factors associated with milking order in lactating dairy cows

    Contributor(s):: Berry, Donagh P., McCarthy, John

    The ability to rapidly identify temporal deviations of an animal from its norm will be important in the management of individual cows in large herds. Furthermore, predictors of genetic merit for especially health traits are useful to augment the accuracy of selection, and thus genetic gain, in...

  5. Estimation of genetic parameters for behavior based on results of German Shepherd Dogs in Switzerland

    Contributor(s):: Meyer, Franziska, Schawalder, Peter, Gaillard, Claude, Dolf, Gaudenz

    The objective of this study was to estimate heritabilities and correlations of seven behavioral traits in German Shepherd Dogs in Switzerland as well as breeding values for this population. Data from 4855 animals having taken the standardized behavior test of the German Shepherd Dog Club of...

  6. Effect of short road journeys on behaviour and some blood variables related to welfare in young bulls

    Contributor(s):: Cafazzo, Simona, Magnani, Diego, Calà, Pietro, Razzuoli, Elisabetta, Gerardi, Gabriele, Bernardini, Daniele, Amadori, Massimo, Costa, Leonardo Nanni

    Many studies have focused on the transport of cattle to fattening farms or to slaughterhouses but there is little information concerning the transport of young bulls delivered to the genetic test stations for selection. Due to the high expected value of young AI candidate bulls, their transport...

  7. Evolution of facial muscle anatomy in dogs

    Contributor(s):: Kaminski, J., Waller, B. M., Diogo, R., Hartstone-Rose, A., Burrows, A. M.

    Domestication shaped wolves into dogs and transformed both their behavior and their anatomy. Here we show that, in only 33,000 y, domestication transformed the facial muscle anatomy of dogs specifically for facial communication with humans. Based on dissections of dog and wolf heads, we show that...

  8. Behavior and personality analysis in cloned working dog candidates 복제 기능견 후보의 행동과 성격 분석

    Full-text: Available

    | Contributor(s):: Jin Choi

    Cloning specific individuals is the way to produce targeted animals. This makes newborns without surplus animals which should be adapted to new families afterwards or supported by institutions for whole life. Cloning excellent dogs had been started from this point. Many cloned dogs have been...

  9. Is evolution of domestication driven by tameness? A selective review with focus on chickens

    | Contributor(s):: Agnvall, Beatrix, Bélteky, Johan, Katajamaa, Rebecca, Jensen, Per

    Domestication of animals offers unique possibilities to study evolutionary changes caused by similar selection pressures across a range of species. Animals from separate genera tend to develop a suite of phenotypic alterations referred to as "the domesticated phenotype". This involves changes in...

  10. Homozygosity for Mobile Element Insertions Associated with WBSCR17 Could Predict Success in Assistance Dog Training Programs

    | Contributor(s):: Tandon, D., Ressler, K., Petticord, D., Papa, A., Jiranek, J., Wilkinson, R., Kartzinel, R. Y., Ostrander, E. A., Burney, N., Borden, C., Udell, M. A. R., VonHoldt, B. M.

  11. To save the bees or not to save the bees: honey bee health in the Anthropocene

    | Contributor(s):: Andrews, Eleanor

  12. Preventing skeletal and neurological problems in guide dogs for the blind and other working dogs

    | Contributor(s):: Evans, K. M., Lewis, T. W.

  13. "Genetics and the Social Behavior of the Dog" Revisited: Searching for Genes Relating to Personality in Dogs.

    | Contributor(s):: Enikõ Kubinyi, Mária Sasvári-Székely, Adám Miklósi

  14. Hippotherapy Capstone

    | Contributor(s):: Autumn O'Hara

    Therapists work with many children with many different diagnoses. One of the most prevalent diagnosis is Autism Spectrum Disorder (ASD). According to recent statistics, available from the Centers for Disease Control and Prevention (CDC), 1 in 68 children are diagnosed with ASD; which is a...

  15. 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...

  16. 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...

  17. 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...

  18. 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...

  19. 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...
