  1. The Controversy on Fish Pain: A Veterinarian’s Perspective

    Contributor(s):: Chatigny, Frederic

    Fish welfare is still a relatively new field. As such, regulations and protocols to ensure fish welfare are currently limited and vary considerably in different jurisdictions. This is in part because of the ongoing controversy as to whether or not fish feel pain. This controversy has persisted...

  2. A review of pain assessment techniques and pharmacological approaches to pain relief after bovine castration: Practical implications for cattle production within the United States

    Contributor(s):: Coetzee, Johann F.

    Castration of male calves destined for beef production is a common livestock management practice in the United States amounting to approximately 7 million procedures per year. Recently there has been renewed interest in identifying methods to reduce pain associated with dehorning and castration....

  3. Identifying and preventing pain during and after surgery in farm animals

    Contributor(s):: Walker, Kristen A., Duffield, Todd F., Weary, Daniel M.

    Pain research in farm animals has focused on routine husbandry procedures such as dehorning; much less known about the pain associated with the other surgeries such as those required for displaced abomasum and caesarean delivery. We review the literature on pain in farm animals due to non-routine...

  4. A comparison of a manual and an automated behavioural analysis method for assessing post-operative pain in mice

    Contributor(s):: Miller, Amy L., Flecknell, Paul A., Leach, Matthew C., Roughan, John V.

    Current methods of identifying and analysing behavioural signs of pain in mice are highly time consuming and labour intensive. HomeCageScan (HCS) is an automated analysis system that may offer an alternative to manual scoring. Thirty-two male mice undergoing vasectomy were filmed before and at 1h...

  5. Addressing pain caused by mulesing in sheep

    Contributor(s):: Fisher, Andrew D.

    The surgical operation of mulesing cuts wool-bearing and wrinkled skin from the perineal region and adjoining hindquarters of Australian Merino sheep, and has been shown in combination with tail docking to provide significantly enhanced protection against flystrike for the remainder of the...

  6. A single dose of ketoprofen in the immediate postpartum period has the potential to improve dairy calf welfare in the first 48 h of life

    Contributor(s):: Gladden, Nicola, Ellis, Kathryn, Martin, Jessica, Viora, Lorenzo, McKeegan, Dorothy

    The welfare impact of birth on newborn calves has rarely been studied. Dystocia in particular may have significant welfare costs for calves. While analgesia is sometimes provided to calves born to difficult parturition by veterinary surgeons in practice, it is not known if this is actually...

  7. Qualitative Behavioural Assessment of Bos indicus cattle after surgical castration

    Contributor(s):: Vindevoghel, Thinza V., Fleming, Patricia A., Hyndman, Timothy H., Musk, Gabrielle C., Laurence, Michael, Collins, Teresa

    There are various methods to perform castration of cattle, but surgical castration is the most common. Although it is well documented that surgical procedures inflict pain, analgesic use is usually omitted for surgical castration of production animals in Australia. This study compares the...

  8. Behavioural responses of fish larvae modulated by analgesic drugs after a stress exposure

    Contributor(s):: Lopez-Luna, Javier, Canty, Martin N., Al-Jubouri, Qussay, Al-Nuaimy, Waleed, Sneddon, Lynne U.

    Fish are known to respond to a wide range of irritant chemicals, displaying clear behavioural changes after exposure to potentially noxious stimuli. Recent evidence shows that these agents can have an impact on larval forms of fish. However, very little information is available on the effects of...

  9. Impact of analgesic drugs on the behavioural responses of larval zebrafish to potentially noxious temperatures

    Contributor(s):: Lopez-Luna, Javier, Al-Jubouri, Qussay, Al-Nuaimy, Waleed, Sneddon, Lynne U.

    Recent studies have demonstrated that fish exhibit behavioural responses to noxious stimuli, including mechanical, chemical or thermal stimulation. In many cases, these responses are characterised by a reduction in the locomotor activity, which in turn can be ameliorated by using appropriate...

  10. Exploring the efficacy of immersion analgesics in zebrafish using an integrative approach

    Contributor(s):: Schroeder, Paul G., Sneddon, Lynne U.

    Home Office guidelines recommend the use of analgesics for all protected species, including fish during scientific procedures likely to result in pain, suffering, distress and lasting harm. In larger fish species some drugs have shown efficacy in terms of perioperative analgesia when administered...

  11. Buprenorphine via drinking water and combined oral-injection protocols for pain relief in mice

    Contributor(s):: Sauer, Mareike, Fleischmann, Thea, Lipiski, Miriam, Arras, Margarete, Jirkof, Paulin

    Buprenorphine is the opioid analgesic most commonly used in laboratory mice. However, to maintain therapeutically effective serum levels, repeated injections are required. To overcome negative aspects of restraint and injection, oral self-administration is a promising alternative but has been...

  12. Effect of analgesic strategies on pain behaviour associated with combined ring castration and hot iron tail docking in Merino lambs

    Contributor(s):: Kells, Nikki J., Beausoleil, Ngaio J., R Godfrey, A. Jonathan, E Littlewood, Katherine, Ward, R. Neil, Johnson, Craig B.

    Most countries don’t require analgesia to be provided to lambs

  13. Effects of carprofen, meloxicam and butorphanol on broiler chickens' performance in mobility tests

    Contributor(s):: Hothersall, B., Caplen, G., Parker, R., Nicol, C. J., Waterman-Pearson, A. E., Weeks, C. A., Murrell, J. C.

    Lame broiler chickens perform poorly in standardised mobility tests and have nociceptive thresholds that differ from those of non-lame birds, even when confounding factors such as differences in bodyweight are accounted for. This study investigated whether these altered responses could be due to...

  14. The effect of isoflurane anaesthesia and buprenorphine on the mouse grimace scale and behaviour in CBA and DBA/2 mice

    Contributor(s):: Miller, A., Kitson, G., Skalkoyannis, B., Leach, M.

    Prevention or alleviation of pain in laboratory mice is a fundamental requirement of in vivo research. The mouse grimace scale (MGS) has the potential to be an effective and rapid means of assessing pain and analgesic efficacy in laboratory mice. Preliminary studies have demonstrated its...

  15. Tales about tails: is the mutilation of animals justifiable in their best interests or in ours?

    Contributor(s):: Edwards, S., Bennett, P., Appleby, M. C., Weary, D. M., Sandoe, P.

    Tail docking, involving surgical or non-surgical removal of a portion of the tail, is one of the most widely carried out and contentious mutilations inflicted by humans on animals. To differing extents, this procedure is carried out on farm livestock, draught animals and companion animals. The...

  16. Pain detection and amelioration in animals on the farm: issues and options

    Contributor(s):: Anil, L., Anil, S. S., Deen, J.

    Pain in nonhuman animals is a difficult concept to identify and measure. This article briefly describes the consequences of pain in animals on the farm and explains the reasons for the minimal use of analgesics in farmed animals. Pain can have implications for both animal welfare and economics....

  17. The effect of morphine on changes in behaviour and physiology in intraperitoneally vaccinated Atlantic salmon ( Salmo salar)

    Contributor(s):: Nordgreen, J., Bjorge, M. H., Janczak, A. M., Poppe, T., Koppang, E. O., Ranheim, B., Horsberg, T. E.

  18. An ethicist's commentary on the technician told to withhold analgesia

    Contributor(s):: Rollin, B. E.

  19. A review of the welfare consequences of surgical castration in piglets and the evaluation of non-surgical methods

    Contributor(s):: Prunier, A., Bonneau, M., Borell, E. H. von, Cinotti, S., Gunn, M., Fredriksen, B., Giersing, M., Morton, D. B., Tuyttens, F. A. M., Velarde, A.

  20. Consumer attitudes towards alternatives to piglet castration without pain relief in organic farming: qualitative results from Germany

    Contributor(s):: Heid, A., Hamm, U.
