    Contributor(s):: Leslie, E., Hernandez-Jover, M., Newman, R., Holyoake, P.

    Suckling piglets are routinely identified to assist with their day-to-day management. A total of 120 suckling piglets were used to determine and compare the short-term pain responses to a number of identification methodologies, including: ear notching, ear tagging and intraperitoneal injection...

  8. Behavioural responses of juvenile steller sea lions to abdominal surgery: developing an assessment of post-operative pain

    Contributor(s):: Walker, K. A., Horning, M., Mellish, J. A. E., Weary, D. M.

    Marking and tracking of marine mammals is required to gain a better understanding of life history traits; however, some marking procedures used are likely painful. Recent technological advances include intra-abdominally implanted archival telemetry devices for the life-long monitoring of...

  9. Dairy cows prefer shade that offers greater protection against solar radiation in summer: shade use, behaviour, and body temperature

    Contributor(s):: Schutz, K. E., Rogers, A. R., Cox, N. R., Tucker, C. B.

    There is considerable evidence that shade is a valuable resource for cattle in summer, but less is known about the important design features of effective shade. The aim of this experiment was to investigate if lactating dairy cows have a preference for shade that offers greater protection against...

  10. Day-old chicks categorised on latency to peck, exhibit a stable fear pattern until 15 days of age

    Contributor(s):: Salvatierra, N. A., Arce, A.

    Day-old chicks (n=24) of both sexes were individually categorized on the latency to peck pebbles and termed as high latency (HL), moderate latency (ML) or low latency (LL). Anxiolytic doses of diazepam diminished the latency only in the HL category, suggesting that it is the most anxious...

  11. Effects of an oral dose of acetyl salicylate at tail docking on the behaviour of lambs aged three to six weeks

    Contributor(s):: Pollard, J. C., Roos, V., Littlejohn, R. P.

    To investigate a practical method of providing analgesia for docking of lambs' tails, the effectiveness of an oral dose of aspirin (acetyl salicylate) in reducing discomfort behaviour immediately following application of elastrator rings, was evaluated. The study, conducted in New Zealand,...

  12. Effects of haloperidol, a dopamine D2 receptor antagonist, on feather pecking behaviour in laying hens

    Contributor(s):: Kjaer, J. B., Hjarvard, B. M., Jensen, K. H., Hansen-Moller, J., Larsen, O. N.

    Two experiments investigating general behavioural activity and specific pecking behaviour in laying hens under the effect of a dopamine D2 receptor antagonist, haloperidol, were performed. In experiment 1, a total of 240 White Leghorn hens aged 70 weeks were housed in 30 floor pens. Fifty-five of...

  13. Evaluating methods of gas euthanasia for laboratory mice

    Contributor(s):: Makowska, I. J., Vickers, L., Mancell, J., Weary, D. M.

    Laboratory mice are most commonly killed with carbon dioxide (CO2), a gas they may find aversive. The aim of this study was to use approach-avoidance testing to record mouse responses to CO2 and to four alternatives: argon, carbon monoxide (CO), and the inhalant anaesthetics halothane and...

  14. How important is shade to dairy cattle? Choice between shade or lying following different levels of lying deprivation

    Contributor(s):: Schutz, K. E., Cox, N. R., Matthews, L. R.

    Provision of shade to dairy cattle in summer can alleviate negative effects of heat stress. The aim of this study was to investigate the relative importance of shade to lactating dairy cows in different ambient weather conditions in summer. The motivation to use shade was compared to the...

  15. Rat aversion to induction with inhalant anaesthetics

    Contributor(s):: Makowska, I. J., Weary, D. M.

    The most common method of euthanasia of laboratory rodents is exposure to carbon dioxide (CO2), but recent studies have shown that rodents find this gas aversive. Inhalant anaesthetics such as halothane and isoflurane are commonly used to induce unconsciousness in small animals and may be a...

  16. Stimulation of serotonin (5-HT) activity reduces spontaneous stereotypies in female but not in male bank voles ( Clethrionomys glareolus ). Stereotyping female voles as a new animal model for human anxiety and mood disorders?

    Contributor(s):: Schoenecker, B., Heller, K. E.

    Spontaneously stereotyping female and male bank voles were injected daily (except on days assigned for monitoring behaviour) during 3 weeks with placebo, the neurolepticum clozapine or the SSRI antidepressant citalopram. Clozapine blocks dopamine (DA) receptors and acts as a partial serotonin...

  17. The evidence for pain in fish: the use of morphine as an analgesic

    Contributor(s):: Sneddon, L. U.

    This paper discusses the evidence for pain perception in fish and presents new data on morphine analgesia in fish.
