  1. Alternative housing for sows and litters 1. Effects of sow-controlled housing on responses to weaning

    Contributor(s): Pajor, E. A., Weary, D. M., Fraser, D., Kramer, D. L.

    A sow-controlled housing system and its affects on production and welfare problems resulting from the abrupt separation of piglets from sows at weaning was investigated. 44 sows and litters were housed during lactation in either a 'confined' pen where the sow and litter were kept together, or a...

  2. Alternative housing for sows and litters. Part 3. Effects of piglet diet quality and sow-controlled housing on performance and behaviour

    Contributor(s): Pajor, E. A., Weary, D. M., Caceres, C., Fraser, D., Kramer, D. L.

    We studied how "sow-controlled" housing (i.e. housing where sows can leave their piglets at will) affects the behaviour and performance of sows and litters when tested under near-commercial conditions and with two different levels of piglet diet quality. Sows and litters were housed in pens where...

  3. Alternative housing for sows and litters. Part 4. Effects of sow-controlled housing combined with a communal piglet area on pre- and post-weaning behaviour and performance

    Contributor(s): Weary, D. M., Pajor, E. A., Bonenfant, M., Fraser, D., Kramer, D. L.

    Previous experimental work has shown modest and variable production and welfare benefits for the lactating sow and piglets when sows are allowed to separate themselves temporarily from their piglets, or when piglets have access to a communal creep area sufficiently attractive that they spend...

  4. Alternative housing for sows and litters. Part 5. Individual differences in the maternal behaviour of sows

    Contributor(s): Pitts, A. D., Weary, D. M., Fraser, D., Pajor, E. A., Kramer, D. L.

    'Sow-controlled' housing has been developed to address welfare and production concerns associated with close confinement of the lactating sow and her litter, by permitting the sow to leave the litter at will. However, there is a risk that variation in the use of the piglet-free ('get-away') area...

  5. Alternative housing for sows and litters: 2. Effects of a communal piglet area on pre- and post-weaning behaviour and performance

    Contributor(s): Weary, D. M., Pajor, E. A., Bonenfant, M., Ross, S. K., Fraser, D., Kramer, D. L.

    An experiment was conducted to determine how allowing piglets access to a communal area affects pre-weaning and post-weaning behaviour and performance. Litters were housed in pens with sows in crates until piglets reached 11 days of age. For 10 experimental cohorts, barriers between the pens of...

  6. Alternatives to nose-ringing in outdoor sows. 1. The provision of a sacrificial rooting area

    Contributor(s): Bornett, H. L. I., Edge, H. L., Edwards, S. A.

    The nose-ringing of outdoor pigs (Sus scrofa) is commonly practised in many countries as a means to inhibit rooting and reduce pasture damage and soil erosion. This practice has been questioned on ethical grounds and alternatives are being sought. Sixteen multiparous pregnant sows were housed in...

  7. Ameliorating nonhuman animals' lives: Erin McKenna's pets, people, and pragmatism

    Contributor(s): Palop, L. de T.

    This review article discusses Erin McKenna's pragmatist theory concerning the ethical treatment of companion animals, which she lays out in Pets, People and Pragmatism. McKenna develops a middle-ground view between the two opposite positions that frame the current debate on companion animals,...

  10. An anti-barking muzzle for dogs and its short-term effects on behaviour and saliva cortisol concentrations

    Contributor(s): Cronin, G. M., Hemsworth, P. H., Barnett, J. L., Jongman, E. C., Newman, E. A., McCauley, I.

    A commercial anti-barking muzzle for dogs was tested during winter on Australian Kelpies at a commercial breeding kennel, to examine the effects of the device on dog behaviour and welfare. The trial involved 16 dogs (paired on sex and age); one dog per pair was allocated at random to the Muzzle...

  11. 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....

  12. An assessment of several potential enrichment devices for feedlot cattle

    Contributor(s): Wilson, S. C., Mitlohner, F. M., Morrow-Tesch, J., Dailey, J. W., McGlone, J. J.

    The behaviour of Charolais cross heifers kept in experimental feedlot pens (3 pens, N=10 per pen) was observed for frequency and duration of use of and percentages of animals interacting with five environmental potential enrichment devices (PEDs) over a period of 22 days. The PEDs tested were:...

  13. An attachment perspective on human-pet relationships: Conceptualization and assessment of pet attachment orientations

    Journal Articles | Contributor(s): Zilcha-Mano, Sigal, Mikulincer, Mario, Shaver, Phillip R.

    In a series of studies we used attachment theory as a framework to examine human–pet relationships. We proposed that, as in interpersonal relationships, people differ in their degree of anxious or avoidant attachment to their pets, and that these individual differences influence...

  15. An automatic system to monitor lying, standing and walking behaviour of grazing animals

    Journal Articles | Contributor(s): Champion, R. A., Rutter, S. M., Penning, P. D.

    Sensors incorporating mercury tilt switches were used to measure the lying, standing and walking behaviour of grazing cattle and sheep. The lying/standing sensor was suspended below the animal, whilst the walking sensor was fitted to the shin of the animal's foreleg. Both switches gave a...

  16. An automatic system to record foraging behaviour in free-ranging ruminants

    Journal Articles | Contributor(s): Rutter, S. M., Champion, R. A., Penning, P. D.

    Precise measurements of grazing behaviour are required to develop an understanding of the factors affecting the foraging behaviour of free-ranging domestic ruminants. An automatic, microcomputer-based system for the digital recording of the jaw movements of free-ranging cattle and sheep is...

  17. An empirical investigation of two assumptions of motivation testing in captive starlings ( Sturnus vulgaris ): do animals have an energy budget to 'spend'? and does cost reduce demand? (Special Issue: Animal suffering and welfare.)

    Journal Articles | Contributor(s): Asher, L., Kirkden, R. D., Bateson, M.

    The use of demand curves to derive estimates of motivational strength is a popular method for measuring animals' preferences for a range of different resources in applied animal behaviour research. In a typical experiment, an animal pays a gradually increasing cost (e.g. by pushing through a...

  18. An epidemiological analysis of dog behavior problems presented to an Australian behavior clinic, with associated risk factors

    Journal Articles | Contributor(s): Ramazan Col, Cam Day, Clive J. C. Phillips

    Records of dogs presented to a behavior clinic servicing the eastern seaboard of Australia in and around Brisbane and the Gold Coast were analyzed for principal behavior problems and the related factors, from information recorded at the time that the owner approached the clinic for assistance....

  20. An ethical viewpoint: the role of veterinarians and behaviourists in ensuring good husbandry for cats. (Special issue: Feline behavior)

    Journal Articles | Contributor(s): Neville, P. F.

    Cat owners commonly consider their pets to be members of their families, and many factors contribute to a high level of owner attachment to their cats. Suppression of a cat's emotional needs in favour of the emotional requirements of the owner may produce a less satisfactory relationship for the...
