    Contributor(s):: Burkemper, M. C., Pairis-Garcia, M. D., Moraes, L. E., Park, R. M., Moeller, S. J.

    The objective of this study was to find a practical means of reducing pain associated with surgical castration by evaluating the effects of oral meloxicam and topical lidocaine, separately and in combination, on behavioral indicators of pain in piglets. Two hundred thirty-five piglets were...

  2. Does Anthropomorphism of Dogs Affect Pain Perception in Animal-Assisted Interventions? An Exploratory Study

    Contributor(s):: Turner-Collins, Clare, Breitenbecher, Kimberly H.

    The purpose of this exploratory study was to determine the effects of anthropomorphism of a therapy dog on pain perception during an animal-assisted intervention. Participants were 32 college women who were randomly assigned to the anthropomorphism condition or the control condition. All...

  3. Social context and other factors influence the behavioural expression of pain by lambs

    Contributor(s):: Guesgen, M. J., Beausoleil, N. J., Minot, E. O., Stewart, M., Stafford, K. J.

    There is evidence that the presence of a conspecific can alter the experience of pain in humans and other animals. This ‘social buffering’ may be mediated by factors such as relatedness and familiarity. This study investigates whether and how the social context affects the behavioural response of...

  4. Positive affective state induced by opioid analgesia in laying hens with bone fractures

    Contributor(s):: Nasr, M. A. F., Browne, W. J., Caplen, G., Hothersall, B., Murrell, J. C., Nicol, C. J.

    Laying hens with keel fractures (n=35) and control hens with no fractures (n=12) were trained to associate the colour and position of an environment with the effects of either a subcutaneous injection of an opioid analgesic drug (butorphanol) or a subcutaneous injection of saline in a conditioned...

  5. Play behavior as an indicator of animal welfare: Disbudding in dairy calves

    Contributor(s):: Mintline, Erin M., Stewart, Mairi, Rogers, Andrea R., Cox, Neil R., Verkerk, Gwyneth A., Stookey, Joseph M., Webster, James R., Tucker, Cassandra B.

    Play behavior may be reduced during negative experiences (e.g. pain) and serve as an indicator of animal welfare. To test this, the effects of a non-steroidal anti-inflammatory drug (NSAID) and a local anesthetic (LA) on dairy calf play behavior and wound sensitivity of calves after hot-iron...

  6. Pain-suppressed behaviors in the red-tailed hawk (Buteo jamaicensis)

    Contributor(s):: Mazor-Thomas, Jana E., Mann, Phyllis E., Karas, Alicia Z., Tseng, Flo

    Our ability to provide analgesia in wild and exotic patients is hampered by a lack of species-specific information on effective drugs and protocols. One contributing factor is the difficulty of applying data from traditional laboratory tests of nociception to clinical conditions frequently...

  7. Pain expression is linked to personality in horses

    Contributor(s):: Ijichi, Carrie, Collins, Lisa M., Elwood, Robert W.

    Tissue damage may result in pain, inducing protective behaviour such as lameness. Because we cannot directly measure an animal's subjective experience, pain research and veterinary assessment rely on these behavioural indicators when quantifying pain. This assumes that pain expression is...

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

    Contributor(s):: Nordgreen, Janicke, Bjørge, Mette Helen, Janczak, Andrew M., Poppe, Trygve, Koppang, Erling Olaf, Ranheim, Birgit, Horsberg, Tor Einar

    Granulomatous peritonitis is often induced by intraperitoneal vaccination in fish. Peritonitis is a very painful condition in mammals, but little is known about how fish experience this condition. In a previous experiment we found increased latency to eat and a tendency to decreased swimming...

  9. The effect of ketoprofen on post-partum behaviour in sows

    Contributor(s):: Viitasaari, Elina, Raekallio, Marja, Heinonen, Mari, Valros, Anna, Peltoniemi, Olli, Hänninen, Laura

    A randomized, double-blinded, placebo controlled trial was conducted in order to estimate pain-related behavioural changes of sows in early lactation. Ketoprofen (KET) was used (3mg/kg BW) intramuscularly for three consecutive days post-partum (p.p.) on 19 sows. Nineteen sows were used as a...

  10. Critical care and survival of fragile animals: The case of Prrxl1 knockout mice

    Contributor(s):: Monteiro, Clara, Dourado, Margarida, Matos, Mariana, Duarte, Isabel, Lamas, Sofia, Galhardo, Vasco, Lima, Deolinda

    The generation of genetically modified animal models in which a given gene is permanently deleted or overexpressed, sometimes results in fragile phenotypes characterized by high morbidity and premature death. This undesired outcome creates important welfare difficulties and poses a huge...

  11. A comparison of welfare outcomes for weaner and mature Bos indicus bulls surgically or tension band castrated with or without analgesia: 2. Responses related to stress, health and productivity

    Contributor(s):: Petherick, J. Carol, Small, Alison H., Mayer, David G., Colditz, Ian G., Ferguson, Drewe M., Stafford, Kevin J.

    Tension banding castration of cattle is gaining favour because it is relatively simple to perform and is promoted by retailers of the banders as a humane castration method. Two experiments were conducted, under tropical conditions using Bos indicus bulls comparing tension banding (Band) and...

  12. A comparison of welfare outcomes for weaner and mature Bos indicus bulls surgically or tension band castrated with or without analgesia: 1. Behavioural responses

    Contributor(s):: Petherick, J. Carol, Small, Alison H., Mayer, David G., Colditz, Ian G., Ferguson, Drewe M., Stafford, Kevin J.

    Tension-band castration of cattle is gaining favour because it is relatively simple to perform and is promoted by retailers of the devices as a humane castration method. Furthermore, retailers encourage delaying castration to exploit the superior growth rates of bulls compared with steers. Two...

  13. Antinociceptive effects of buprenorphine in zebrafish larvae: An alternative for rodent models to study pain and nociception?

    Contributor(s):: Steenbergen, Peter J., Bardine, Nabila

    The underlying processes of nociception and pain are, despite the rodent models available, still not fully understood. One of the drawbacks of rodent model systems is the difficulty to screen compound libraries for their influence on nociception, thus slowing down the discovery of novel...

  14. Administration of a NSAID (meloxicam) affects lying behaviour after caesarean section in beef cows

    Contributor(s):: Barrier, Alice C., Coombs, Tamsin M., Dwyer, Cathy M., Haskell, Marie J., Goby, Laurent

    Very little is known about the pain experienced by cattle following caesarean section and hence little consideration has been given to managing it. Thus the purpose of this study was to investigate activity-related behavioural changes in response to pain, by pre-emptively administering a long...

  15. Parturition progress and behaviours in dairy cows with calving difficulty

    Contributor(s):: Barrier, Alice C., Haskell, Marie J., Macrae, Alastair I., Dwyer, Cathy M.

    The welfare of dairy cows and their calves is compromised following a difficult calving. A better understanding of what happens during a difficult calving is needed to help prevent and alleviate adverse consequences through early diagnosis and/or pain mitigation. The objectives of this study were...

  16. Pain issues in poultry

    Contributor(s):: Gentle, Michael J.

    This review highlights the possible pain experienced by layer and broiler poultry in modern husbandry conditions. Receptors which respond to noxous stimulation (nociceptors) have been identified and physiologically characterised in many different part of the body of the chicken including the...

  17. Pain and discomfort caused by parturition in cows and sows

    Contributor(s):: Mainau, Eva, Manteca, Xavier

    This review focuses on parturition as a painful process in cows and sows. Firstly, the different stages of parturition associated to the origin and transmission of pain stimuli are described. Hypoalgesia during the late pregnancy and parturition has been shown, perhaps as an endogenous defence...

  18. The long and short of it: A review of tail docking in farm animals

    Contributor(s):: Sutherland, Mhairi A., Tucker, Cassandra B.

    Tail docking involves amputating a portion of the tail for a variety of reasons. We review the scientific evidence for the rationale for tail docking, a description of the different methods used, the pain response to the procedure and the effectiveness of pain alleviation, and, finally, the...

  19. Eyestalk ablation procedures to minimize pain in the freshwater prawn Macrobrachium americanum

    Contributor(s):: Diarte-Plata, Genaro, Sainz-Hernández, Juan C., Aguiñaga-Cruz, Jazmín A., Fierro-Coronado, Jesús A., Polanco-Torres, Arturo, Puente-Palazuelos, Catalina

    This article proposes an enhanced and less painful procedure to eliminate the flow of hormones from the X organ sinus gland in adult Macrobrachium americanum. Three groups and two controls were analyzed to determine the amount of stress caused by the following: (1) unilateral eyestalk ablation,...

  20. Ewes are more attentive to their offspring experiencing pain but not stress

    Contributor(s):: Hild, Sophie, Clark, Corinna C. A., Dwyer, Catherine M., Murrell, Joanna C., Mendl, Mike, Zanella, Adroaldo J.

    The goal of this experiment was to detect if maternal care by ewes could be effective in mitigating psychological or physiological stress or pain in their offspring. We hypothesised that ewes are able to recognise when their offspring undergo an adverse experience and will adapt their maternal...
