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....

Assessment of acute pain experienced by piglets from ear tagging, ear notching and intraperitoneal injectable transponders
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...
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...
Effect of caustic paste disbudding, using local anaesthesia with and without analgesia, on behaviour and cortisol of calves
Contributor(s):: Stilwell, G., Carvalho, R. C. de, Lima, M. S., Broom, D. M.
We looked at the effects of local anaesthesia with or without a non-steroidal-anti-inflammatory analgesic drug (flunixin-meglumine) on behaviour and plasma cortisol after caustic paste disbudding of 1-month-old calves: at 15 min, 1, 3, 6 and 24 h (Experiment 1; n=32); at 10, 30 and 50 min...
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,...
The effects of the acetic acid "pain" test on feeding, swimming, and respiratory responses of rainbow trout ( Oncorhynchus mykiss )
Contributor(s):: Newby, N. C., Stevens, E. D.
The acetic acid test is commonly used in conscious mammals to determine nociceptive thresholds and efficacy of analgesics. The purpose of the present study was to examine the response of rainbow trout that were not anaesthetised during the acetic acid test. Rainbow trout (n=31) were trained to...
Behavior after ovariohysterectomy in the dog: what's normal?
Contributor(s):: Hardie, E. M., Hansen, B. D., Carroll, G. S.
Twenty dogs were anaesthetized, but did not undergo surgery (control group). 22 dogs underwent laparotomy and ovariohysterectomy (surgery group). Dogs in the control and surgery groups were further assigned on a random basis to either oxymorphone or placebo groups (group O or P). Dogs in group O...
Burdizzo castration of calves less than 1-week old with and without local anaesthesia: short-term behavioural responses and plasma cortisol levels
Contributor(s):: Boesch, D., Steiner, A., Gygax, L., Stauffacher, M.
Castration of calves over 3 weeks of age is considered a painful procedure. It is less clear whether and how much pain is caused by this procedure in very young calves. The aim of the present study was to determine the short-term pain response of 30 calves less than 1-week of age to Burdizzo...
Effects of mulesing and alternative procedures to mulesing on the behaviour and physiology of lambs
Contributor(s):: Hemsworth, P. H., Barnett, J. L., Karlen, G. M., Fisher, A. D., Butler, K. L., Arnold, N. A.
Mulesing involves the surgical removal of skin adjacent to the perineum and tail without anaesthesia or analgesia in lambs. This procedure was developed to reduce the risk of flystrike (cutaneous myiasis) around the perineum. Alternative interventions to mulesing have historically been...
Pain and stress in crustaceans? (Special Issue: Animal suffering and welfare.)
Contributor(s):: Elwood, R. W., Barr, S., Patterson, L.
We consider evidence that crustaceans might experience pain and stress in ways that are analogous to those of vertebrates. Various criteria are applied that might indicate a potential for pain experience: (1) a suitable central nervous system and receptors, (2) avoidance learning, (3) protective...
Physiological measurements after ovariohysterectomy in dogs: what's normal?
Contributor(s):: Hansen, B. D., Hardie, E. M., Carroll, G. S.
Twenty-two pet dogs presented to the North Carolina State University Veterinary Teaching Hospital for elective ovariohysterectomy were treated with oxymorphone 2.5 mg/msuperscript 2 (Surgery-O group, 11 dogs) or placebo (Surgery-P group, 11 dogs) immediately before the induction of anaesthesia...
Voluntary ingestion of buprenorphine in mice
Contributor(s):: Jacobsen, K. R., Kalliokoski, O., Hau, J., Abelson, K. S. P.
Buprenorphine is a widely used analgesic for laboratory rodents. Administration of the drug in a desirable food item for voluntary ingestion is an attractive way to administer the drug non-invasively. However, it is vital that the animals ingest the buprenorphine-food-item mix as desired. The...

Training in behaviour-based post-operative pain scoring in rats - an evaluation based on improved recognition of analgesic requirements
Contributor(s):: Roughan, J. V., Flecknell, P. A.
The objective of the study was to evaluate whether an objective technique based on quantitative behaviour analysis represents a methodological improvement upon a simple subjective approach for assessing post-operative pain in rats. Data were collected during three Phases from 332...
A first description of the physiological and behavioural responses to disbudding in goat kids
Contributor(s):: Alvarez, L., Gutierrez, J.
In order to determine the stress response to disbudding, physiological and behavioural response was investigated in disbudded kids and compared with a control group. Disbudded kids (n=14), were disbudded by thermal cauterisation, and control kids (n=15) received the same management without being...
A preliminary study of behaviour-based indicators of pain in cats
Contributor(s):: Waran, N., Best, L., Williams, V., Salinsky, J., Dale, A., Clarke, N.
The aim of this preliminary study was to identify key behavioural indicators of pain in cats. The behaviour of cats before and after ovariohysterectomy was analysed using a detailed behavioural ethogram. A comparison of behaviours between cats given pre-operative analgesia only and cats given...
