Aspects of juvenile and adolescent environment predict aggression and fear in 12-month-old guide dogs
| Contributor(s):: Serpell, J. A., Duffy, D. L.
Maturational changes in behavior, and the possible influence of the puppy-raising environment on behavioral development, were investigated in a total sample of 978 prospective guide dogs belonging to four different breeds/crosses. All dogs belonged to the same guide dog organization, and had...

The presence of Icelandic leadersheep affects flock behaviour when exposed to a predator test
| Contributor(s):: Brunberg, Emma, Eythórsdóttir, Emma, Dýrmundsson, Ólafur R., Grøva, Lise
Genetic selection in commercial sheep production has mainly focussed on production traits and to a large extent ignoring behavioural traits, such as response towards predators. The Icelandic leadersheep is a sheep breed selected and known for its special behavioural traits, such as leading the...

Brown and white egg-layer strain differences in fearfulness and stress measures
| Contributor(s):: Nelson, Jill R., Settar, Petek, Berger, Emily, Wolc, Anna, O’Sullivan, Neil, Archer, Gregory S.
Different genetic lines of laying hens may show varying levels of fearfulness in response to stressful events or situations. It is important to select appropriate genetic strains when keeping hens in alternative housing systems to minimize health and production issues caused by fear and stress....

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...

Trainability and boldness traits differ between dog breed clusters based on conventional breed categories and genetic relatedness
| Contributor(s):: Turcsán, Borbála, Kubinyi, Enikő, Miklósi, Ádám
Modern dog breeding has given rise to more than 400 breeds differing both in morphology and behaviour. Traditionally, kennel clubs have utilized an artificial category system based on the morphological similarity and historical function of each dog breed. Behavioural comparisons at the...

Relationship between growth rate and oral manipulation, social nosing, and aggression in finishing pigs
| Contributor(s):: Camerlink, Irene, Bijma, Piter, Kemp, Bas, Bolhuis, J. Elizabeth
Pigs may affect each other's health, welfare and productivity through their behaviour. The effect of a pig on the growth rate of its pen mates is partly heritable and is referred to as its social genetic effect. Social genetic effects, also known as indirect genetic effects, have been found in a...

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...

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...

Manifestation of neuronal ceroid lipofuscinosis in Australian Merino sheep: observations on altered behaviour and growth
| Contributor(s):: Cronin, Greg M., Beganovic, Danai F., Sutton, Amanda L., Palmer, David J., Thomson, Peter C., Tammen, Imke
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...

Long-term effects of straw blocks in pens with finishing pigs and the interaction with boar type
| Contributor(s):: Bulens, Anneleen, Van Beirendonck, Sanne, Van Thielen, Jos, Buys, Nadine, Driessen, Bert
This study verified the effect of straw blocks on the behavior and growth of finishing pigs and possible interactions with the genetic background (boar type). A total of 359 finishing pigs, which were offspring from different boar types, were housed in gender-mixed pens with slatted floors. Half...

Environmental enrichment exerts anxiolytic effects in the Indian field mouse (Mus booduga)
| Contributor(s):: Varman, D. R., Ganapathy, Marimuthu, Rajan, K. E.
Environmental enrichment (EE) is known to have behavioral and physiological anxiolytic effects in several animal models. However, it is as yet unclear how EE modulates behavior of wild animals and the underlying molecular mechanisms. The adult male field mouse Mus...

Human perceptions of coat color as an indicator of domestic cat personality
| Contributor(s):: Delgado, M. M., Munera, J. D., Reevy, G. M.
Associations between mammalian coat color and behavior have been investigated in a number of species, most notably the study of silver foxes by the Institute of Cytology and Genetics at the Russian Academy of Sciences. However, the few studies conducted regarding a potential relation between...

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...

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...
