  1. Historical development of horse breeds

    Contributor(s):: Tuncer, S. S., Kozat, S.

    This study was conducted to examine the historical development process of modern horse breeds. Horses are among the few species that have managed to become domesticated on earth. The domestication of horses took place after dogs, goats, sheep, pigs, reindeer and poultry. It is accepted that the...

  4. 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...

  5. 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. 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...

  7. Domesticating animals in Africa : implications of genetic and archaeological findings

    | Contributor(s):: Gifford-Gonzalez, Diane

  8. Are farmed salmon more prone to risk than wild salmon? Susceptibility of juvenile farm, hybrid and wild Atlantic salmon Salmo salar L. to an artificial predator

    | Contributor(s):: Solberg, M. F., Zhang, ZhiWei, Glover, K. A.

    Offspring of farmed Atlantic salmon have been documented to display lower survival than the offspring of wild salmon in the wild. It has been suggested that reduced survival of farmed salmon offspring in the wild could, in part, be explained by increased susceptibility to predation through...

  9. 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...

  10. Comparison of adoption agency breed identification and DNA breed identification of dogs

    | Contributor(s):: Voith, V. L., Ingram, E., Mitsouras, K., Irizarry, K.

    Governmental and other agencies may require dog caregivers (owners) to provide breed identification of their dogs. This study compares breed identification by adoption agencies with identification by DNA analysis in 20 dogs of unknown parentage. Of the 20 dogs who had been adopted from 17...

  11. Genetically modified laboratory animals - what welfare problems do they face?

    | Contributor(s):: Buehr, M., Hjorth, P. J., Hansen, A. K., Sandoe, P.

    In this article, we respond to public concern expressed about the welfare of genetically modified (GM) non-human animals. As a contribution to the debate on this subject, we attempt in this article to determine in what situations the practice of genetic modification in rodents may generate...

  12. Dairy calves' adaptation to group housing with automated feeders

    | Contributor(s):: Fujiwara, M., Rushen, J., Passille, A. M. de

    Group housing of dairy calves with automated milk feeders has likely welfare and labour saving advantages but delays in the calves adapting to the feeding system may reduce these advantages. We examined factors that influence calves' adaptation to the feeders. In Exp. 1, 77 Holstein calves were...

  13. Purebred dogs and canine wellbeing

    Full-text: Available

    | Contributor(s):: Jeppsson, S.

    Breeders of purebred dogs usually have several goals they want to accomplish, of which canine wellbeing is one. The purpose of this article is to investigate what we ought to do given this goal. Breeders typically think that they fulfil their wellbeing-related duties by doing the best they can...

  14. Relationships between young stallions' temperament and their behavioral reactions during standardized veterinary examinations

    | Contributor(s):: Peeters, M., Verwilghen, D., Serteyn, D., Vandenheede, M.

    Horse handling and veterinary examination can induce hazardous stress reactions. Such reactions occur especially in young and less-trained horses, particularly stallions, and make their handling a risk for breeders, grooms, and medical staff. Moreover, these stressful situations will affect the...

  15. 'Bling with bite' - the rise of status and weapon dogs

    | Contributor(s):: Harding, S.

  16. The use of quantitative risk assessment to assess lifetime welfare outcomes for breech strike and mulesing management options in Merino sheep

    | Contributor(s):: Fisher, A. D., Giraudo, A., Martin, P. A. J., Paton, M. W.

  17. Canine olfactory genetics

    | Contributor(s):: Quignon, P., Robin, S., Galibert, F.

  18. Organization and expression of canine olfactory receptor genes

    Full-text: Available

    | Contributor(s):: Issel-Tarver, L., Rine, J.

    Four members of the canine olfactory receptor gene family were characterized. The predicted proteins shared 40-64% identity with previously identified olfactory receptors. The four subfamilies identified in Southern hybridization experiments had as few as 2 and as many as 20 members. All four...

  19. Breeding for better welfare: genetic goals for broiler chickens and their parents

    | Contributor(s):: Dawkins, M. S., Layton, R.

  20. 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...
