  1. Effects of confinement duration and parity on behavioural responses and the degree of psychological fear in pregnant sows

    Contributor(s):: Zhang, Ming-yue, Li, Xiang, Zhang, Xiao-hui, Liu, Hong-gui, Li, Jian-hong, Bao, Jun

    The aim of this study was to evaluate the effects of space restriction stress on the behavior of different parity sows, and it is necessary to understand such effects due to space restriction to improve the welfare of the sows in confined conditions. We selected 264 pregnant sows (Large White) at...

  2. Confinement of sows 24h before expected farrowing affects the performance of nest building behaviours but not progress of parturition

    Contributor(s):: Hansen, Christian F., Hales, Janni, Weber, Pernille M., Edwards, Sandra A., Moustsen, Vivi A.

    The effects of confinement prior to farrowing on the performance of nest building behaviour and progress of parturition were investigated using hyper prolific sows. Forty first parity and 41second/third parity sows were allocated to one of two treatments: loose housed (40) or confined (41). All...

  3. Using a dog demography field study to inform the development of an agent-based computer simulation. Evaluating owned dog population control interventions in a small, semi-urban community in Mexico

    Contributor(s):: Luz Maria Kisiel

    This thesis evaluates the potential effects of different dog population control interventions in a small, semi-urban community in Mexico. First, a cross-sectional study was conducted to characterize dog ecology and demography in Villa de Tezontepec, Hidalgo. Approximately 65% of the households...

  4. Orca Behavior and Subsequent Aggression Associated with Oceanarium Confinement

    Full-text: Available

    | Contributor(s):: Robert Anderson, Robyn Waayers, Andrew Knight

    Based on neuroanatomical indices such as brain size and encephalization quotient, orcas are among the most intelligent animals on Earth. They display a range of complex behaviors indicative of social intelligence, but these are difficult to study in the open ocean where protective laws may...

  5. A Case Study of Behaviour and Performance of Confined or Pastured Cows During the Dry Period

    | Contributor(s):: Randi A. Black, Peter D. Krawczel

    The objectives of this study were to determine the effect of the dry cow management system (pasture or confined) on: (1) lying behaviour and activity; (2) feeding and heat stress behaviours; (3) intramammary infections, postpartum. Non-lactating Holstein cows were assigned to either deep-bedded,...

  6. Factors affecting the welfare and adoption rate of cats in an animal shelter

    | Contributor(s):: Nadine Gourkow

    Rates of adoption for adult cats in animal shelters have always been very low, thus these animals are often subjected to euthanasia and/or long periods of confinement. Furthermore, housing of shelter cats has traditionally focused on disease prevention; this has led to the use of barren,...

  7. A critically appraised topic (CAT) to compare the effects of single and multi-cat housing on physiological and behavioural measures of stress in domestic cats in confined environments

    Full-text: Available

    | Contributor(s):: Lauren R Finka, Sarah LH Ellis, Jenny Stavisky

    BackgroundDomestic cats have evolved from solitary, asocial predators and whilst they may display social behaviours, they can still exist as solitary survivors. Over-population and relinquishment of pet cats are ubiquitous problems worldwide, and rehoming centres (also known as rescues/ shelters)...

  8. Enriching the Environment of the Laboratory Cat

    | Contributor(s):: Sandra McCune

    Cats are intelligent, highly specialized carnivores. Like many predators, their senses are highly developed (reviewed by Bradshaw 1992). The cat's ability to hear, see and smell outside our own range give it a very different perception of its environment to ours. For example, it has a second...

  9. Do domestic pigs prefer short-term to medium-term confinement?

    | Contributor(s):: Spinka, M., Duncan, I. J. H., Widowski, T. M.

    A preference test was used to demonstrate that gilts have the ability to associate 2 sets of neutral cues with 2 different periods of confinement and water deprivation and to anticipate the long-term consequences of their choice in the test. 12 gilts housed in 2 large, straw-bedded pens were...

  10. Preferences of pregnant sows for wet and dry concrete floors

    | Contributor(s):: Hutson, G. D., Haskell, M. J., Dickenson, L. G., Slinger, D. E.

    Preference was assessed by providing sows with access to two adjacent pens, one with a dry concrete floor and the other with a wet concrete floor. Sows were fed in either the wet pen or dry pen and allowed continuous free access to both pens, or they were confined overnight in one of the pens and...
