  1. 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...

  2. Fresh wood reduces tail and ear biting and increases exploratory behaviour in finishing pigs

    Contributor(s):: Telkanranta, H., Bracke, M. B. M., Valros, A.

    Chewing and rooting are high behavioural priorities in pigs. Lack of suitable materials can lead to abnormal behaviours such as tail and ear biting. In commercial farming, slatted floors limit the use of straw, and various point-source objects have therefore been developed. The crucial challenge...

    Contributor(s):: Scholthof, Karen-Beth G.

  4. Bred for Perfection: Shorthorn Cattle, Collies, and Arabian Horses since 1800 [book review]

    Contributor(s):: Tenner, Edward

  5. Harnessing Heredity In Gilded Age America: Middle Class Mores And Industrial Breeding In A Cultural Context

    Contributor(s):: Thurtle, Phillip

  6. 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...

  7. 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...

  8. Genetic diversity of Toxoplasma gondii in animals and humans

    Contributor(s):: L. David Sibley, Asis Khan, James W. Ajioka, Benjamin M. Rosenthal

    Toxoplasma gondii is one of the most widespread parasites of domestic, wild, and companion animals, and it also commonly infects humans. Toxoplasma gondii has a complex life cycle. Sexual development occurs only in the cat gut, while asexual replication occurs in many vertebrate hosts. These...

  9. Prevalence and antimicrogram of Staphylococcus intermedius group isolates from veterinary staff, companion animals, and the environment in veterinary hospitals in Korea

    Contributor(s):: Youn, JungHo, Yoon, JangWon, Koo, HyeCheong, Lim, SukKyung, Park, YongHo

  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. Measuring emotions toward wildlife: A review of generic methods and instruments

    Contributor(s):: Jacobs, Maarten H., Fehres, Piera, Campbell, Michael

    Researchers are recognizing the importance of studying emotions for understanding human–wildlife interactions. This article reviews generic methods and instruments for assessing emotions, as developed within the affective sciences. Four broad categories of emotion measures can be distinguished:...

  13. A review of the effects of prostaglandins on sexual behavior in boars

    Contributor(s):: Estienne, M. J.

    Artificial insemination (AI) is the primary method of breeding sows in many countries worldwide. In general, semen for AI is collected using the gloved hand technique from boars trained to mount an artificial sow, although automated collection systems have been developed and are in use on some...

  14. Behaviour epigenetics - the connection between environment, stress and welfare

    Contributor(s):: Jensen, P.

    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. Critical care and survival of fragile animals: the case of Prrxl1 knockout mice

    Contributor(s):: Monteiro, C., Dourado, M., Matos, M., Duarte, I., Lamas, S., Galhardo, V., Lima, D.

    The generation of genetically modified animal models in which a given gene is permanently deleted or overexpressed, sometimes results in fragile phenotypes characterized by high morbidity and premature death. This undesired outcome creates important welfare difficulties and poses a huge...

  16. 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...

  17. Nutrition for working and service dogs

    Contributor(s):: Wakshlag, J., Shmalberg, J.

    Conformation, genetics, and behavioral drive are the major determinants of success in canine athletes, although controllable variables, such as training and nutrition, play an important role. The scope and breadth of canine athletic events has expanded dramatically in the past 30 years, but with...

  18. Purebred dogs and canine wellbeing

    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...

  19. Reliability and validity of a questionnaire survey in canine anxiety research

    Contributor(s):: Tiira, K., Lohi, H.

    Canine behavior can be assessed through behavioral testing or questionnaire surveys. Behavioral tests, often observed by independent experts, can provide objective data, but capture only a short behavioral sequence in a defined situation and are practical only for small study cohorts....

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

    Contributor(s):: Rodenburg, T. B.

    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...
