Advancing Genetic Selection and Behavioral Genomics of Working Dogs Through Collaborative Science
| Contributor(s):: Chen, F. L., Zimmermann, M., Hekman, J. P., Lord, K. A., Logan, B., Russenberger, J., Leighton, E. A., Karlsson, E. K.
The ancient partnership between people and dogs is struggling to meet modern day needs, with demand exceeding our capacity to safely breed high-performing and healthy dogs. New statistical genetic approaches and genomic technology have the potential to revolutionize dog breeding, by...
Use of questionnaire-based data to assess dog personality
| Contributor(s):: Pamela Wiener, Marie J. Haskell
The study of dog personality is of general academic interest and also has applications for the management of both working dogs and pets. However, acquiring direct behavioral assessments of large numbers of animals is both time consuming and logistically difficult. An alternative approach that...

Genetic component of cannibalism in Asian seabass Lates Calcarifer
| Contributor(s):: Pham, Van Khang, Truong, Ha Phuong, Nguyen, Dat Khac, Nguyen, Nguyen Hong
Cannibalism in the early phase of growth development has been a major concern for marine finfish, including Asian seabass Lates calcarifer, as it is one of the key factors determining economic return of commercial hatcheries. This study thus explored genetic variation in cannibalism through...
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...
Crib-biting and its heritability in Finnhorses
| Contributor(s):: Hemmann, Karin, Raekallio, Marja, Vainio, Outi, Juga, Jarmo
Crib-biting in horses is a stereotypical oral behaviour with a prevalence of 2.8–15%, varying between breeds. A genetic basis for crib-biting has been suggested by many researchers, but due to incomplete information on families or the lack of a sufficient number of verified crib-biters,...
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...
Breeding against harmful social behaviours in pigs and chickens: State of the art and the way forward
| Contributor(s):: Turner, Simon P.
Harmful social behaviours are prevalent in commercial farming environments and their reduction through economically feasible husbandry changes is challenging. Selective breeding may offer a complementary approach to reduce the expression of these traits. This article explores the progress made in...
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...
Genetic study of stress assessed with infrared thermography during dressage competitions in the Pura Raza Espanol horse
| Contributor(s):: Sánchez, María José, Bartolomé, Ester, Valera, Mercedes
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 Español horse (PRE) Breeding...
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...
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...
Human‐directed social behaviour in dogs shows significant heritability

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...
Divergent selection on feather pecking behaviour in laying hens ( Gallus gallus domesticus )
| Contributor(s):: Kjaer, J. B., Sorensen, P., Su, G.
A selection experiment was initiated in 1996 in which selection for (HP line) and against (LP line) feather pecking was performed. The foundation stock was a White Leghorn layer strain established in 1970 and maintained since then as a random bred control line at the Institute. Six hatches were...
Selection for more confident foxes in Finland and Norway: heritability and selection response for confident behaviour in blue foxes ( Alopex lagopus )
| Contributor(s):: Kenttamies, H., Nordrum, N. V., Brenoe, U. T., Smeds, K., Johannessen, K. R., Bakken, M.
As a part of a Nordic project, 'Selection for more confident foxes', selection experiments with blue foxes lasting 4 years (1995-98) were arranged in Finland and Norway. In Finland, the study was carried out on a private farm with closed selection and production lines. In Norway, the experiment...
Stereotypic behaviour is genetically transmitted in the African striped mouse Rhabdomys pumilio
| Contributor(s):: Schwaibold, U., Pillay, N.
The development of stereotypic behaviour was studied in captive striped mice, Rhabdomys pumilio. Based on the findings of previous studies, it was hypothesized that there is a genetic basis of stereotypy in striped mice. Breeding and cross-fostering experiments were used to test this hypothesis....
