  1. Aspects of juvenile and adolescent environment predict aggression and fear in 12-month-old guide dogs

    Full-text: Available

    | 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...

  2. Protein expression and genetic variability of canine Can f 1 in golden and Labrador retriever service dogs

    Full-text: Available

    | Contributor(s):: Breitenbuecher, C., Belanger, J. M., Levy, K., Mundell, P., Fates, V., Gershony, L., Famula, T. R., Oberbauer, A. M.

    Background: Valued for trainability in diverse tasks, dogs are the primary service animal used to assist individuals with disabilities. Despite their utility, many people in need of service dogs are sensitive to the primary dog allergen, Can f 1, encoded by the Lipocalin 1 gene (LCN1). Several...

  6. CRISPR/Cas9 Technology in Translational Biomedicine

    | Contributor(s):: Leonova, E. I., Gainetdinov, R. R.

  7. 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...

  8. Pharmacological inhibition of histone deacetylase reduces NADPH oxidase expression, oxidative stress and the progression of atherosclerotic lesions in hypercholesterolemic apolipoprotein E-deficient mice; potential implications for human atherosclero

    | Contributor(s):: Manea, S. A., Vlad, M. L., Fenyo, I. M., Lazar, A. G., Raicu, M., Muresian, H., Simionescu, M., Manea, A.

  9. Antiphospholipid syndrome: complement activation, complement gene mutations and therapeutic implications

    | Contributor(s):: Chaturvedi, S., Braunstein, E. M., Brodsky, R. A.

  10. 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....

  11. "We Always Hurt the Things We Love"—Unnoticed Abuse of Companion Animals

    Full-text: Available

    | Contributor(s):: Bernard E. Rollin

    Despite the fact that companion animals enjoy the status of “members of the family” in contemporary society, there are numerous diseases affecting the longevity of these animals and their quality of life. Some of the most pervasive and damaging problems accrue to pedigreed animals...

  12. 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...

  13. 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...

  14. 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...

  15. 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...

  16. 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...

  17. 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...

  18. 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...

  19. 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...

  20. 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...
