  1. Breed differences in canine aggression

    Contributor(s):: Duffy, D. L., Hsu, Y. Y., Serpell, J. A.

    Canine aggression poses serious public health and animal welfare concerns. Most of what is understood about breed differences in aggression comes from reports based on bite statistics, behaviour clinic caseloads, and experts' opinions. Information on breed-specific aggressiveness derived from...

  2. Domestication - from behaviour to genes and back again

    Contributor(s):: Jensen, P.

    During domestication, animals have adapted with respect to behaviour and an array of other traits. This tends to give rise to a specific domestication phenotype, involving similar changes in colour, size, physiology and behaviour among different species. Hence, domestication offers a model for...

  3. Domestication effects on foraging strategies in pigs ( Sus scrofa )

    Contributor(s):: Gustafsson, M., Jensen, P., Jonge, F. H. de, Schuurman, T.

    Eight domestic pigs and 8 crossbred pigs (Holland Landrace x wild boar) were allowed to forage alone in a maze for 30 min on 4 successive days. The maze contained 6 gradually depleting food patches and corridors between them. Pigs obtained the food by manipulating the bucket with the snouts. On...

  4. Effects of origin, experiences early in life, and genetics on bitterweed Hymenoxys odorata consumption by sheep

    Contributor(s):: Frost, R. A., Scott, C. B., Walker, J. W., Hartmann, F. S.

    Bitterweed is one of the most detrimental poisonous plants to sheep production in west central Texas. Sheep typically avoid the plant unless alternative forage is limited. When consumption does occur, some flocks and individuals are able to consume bitterweed and avoid toxicosis. Our objective...

  5. Genetic and environmental effects on piglet survival and maternal behaviour of the farrowing sow

    Contributor(s):: Baxter, E. M., Jarvis, S., Sherwood, L., Farish, M., Roehe, R., Lawrence, A. B., Edwards, S. A.

    There is growing external pressure to abolish the farrowing crate, however alternative farrowing systems need to equal or surpass the performance (i.e. piglet survival) of more restrictive systems. In order to achieve consistent improvement in piglet survival genetic selection strategies...

  6. Genetics and genomics of animal behaviour and welfare - challenges and possibilities. (Special Issue: Farm animal welfare since the Brambell report.)

    Contributor(s):: Jensen, P., Buitenhuis, B., Kjaer, J., Zanella, A., Mormede, P., Pizzari, T.

    Traditionally, the contribution of applied ethology to animal welfare science has concentrated on understanding the reactions of animals to their housing conditions. Domestication has had small effects on fundamental aspects of animal behaviour, and therefore, the needs of present day...

  7. The behavioural, physiological and immunological responses of lambs from two rearing systems and two genotypes to exposure to humans

    Contributor(s):: Goddard, P. J., Fawcett, A. R., Macdonald, A. J., Reid, H. W.

    96 lambs of 2 genotypes (Scottish Blackface: BF and Texel x (Blue-faced Leicester x Scottish Blackface): T) were studied. From birth to weaning 1 of 2 management regimes was applied: extensive (E), whereby animals were handled as little as possible or semi-intensive (I), in which lambs...

  8. Unpredictable mild stressors on laying females influence the composition of Japanese quail eggs and offspring's phenotype

    Contributor(s):: Guibert, F., Richard-Yris, M. A., Lumineau, S., Kotrschal, K., Bertin, A., Petton, C., Mostl, E., Houdelier, C.

    Maternal stress effects on offspring development have been studied largely in rodents and primates, and to a lesser extent in farm animals. Potential lack of knowledge concerning prenatal stress on farm animals is regrettable because they are frequently subjected to a variety of husbandry...

  9. An approach to canine behavioural genetics employing guide dogs for the blind

    Contributor(s):: Takeuchi, Y., Hashizume, C., Arata, S., Inoue-Murayama, M., Maki, T., Hart, B. L., Mori, Y.

    The purpose of this study was to attempt to find related variables of the canine genome with behavioural traits of dogs maintained and tested in a guide dog facility which provided a relatively uniform environment. The study involved 81 Labrador Retrievers that were being trained as guide dogs....

  10. Human-nonhuman chimeras: A regulatory proposal on the blurring of species lines

    Contributor(s):: Nicole E. Kopinski

    The chimera of modern biotechnology is defined broadly as a single organism composed of a mixture of materials from two or more organisms possessing distinct genetic backgrounds. Unlike the United States, which does not regulate chimeras directly, Canada has responded to the unregulated pursuit...

  11. Myth #2: Training is the Key to Success with Autism Assistance Dogs for Children

    10 Aug 2012 | Posted by Patty Dobbs Gross

    by Patty Dobbs Gross I get by with a little help from my friends. ~ John Lennon ''David and North Star's Lego'' One of the biggest misunderstandings about the emerging field...
