“…Some of these behaviours are considered to have no beneficial effects; however, they can be described as attempts to escape and may be interpreted as specific pain behaviour . This methodology was successfully used for estimation of behavioural responses to the pain of castration in calves (Molony et al 1995) or tail docking in lambs (Landa 2003).…”

ABSTRACT:In recent years more attention has been paid to the issue of pain in animals, particularly in association with increasing awareness of animal welfare. It is therefore necessary for veterinarians to be able recognise unambiguously whether an animal suffers from pain. Adult humans suffering from pain can more or less characterise their painful experiences, including the site and intensity of the pain. However, pain in animals is in some aspects more complex and it can be rather difficult to evaluate the seriousness and impact of painful events. Therefore, in animals we have to recognise the signs of pain according to indirect markers which involve behavioural, physiological and finally clinical responses. Moreover, in particular the behavioural changes associated with pain can be along with the general signs also species-specific, and hardly recognisable (and for an inexperienced observer seemingly unimportant) which makes pain assessment even more complicated. Therefore, the current review formulates definitions of pain, its classification and is focused on methods that may facilitate pain recognition in animals, which is crucial for an effective pain assessment and consequent effective pain management. The review combines recent knowledge with well proven facts concerning pain and furthermore also highlights the author's own research on pain assessment.

“…Other potential methods for the reduction of acute pain induced by rubber ring castration and/or tail docking have, so far, proved ineffective. These include suckling or sucking glucose or colostrum from a syringe immediately before the treatment (Landa 2000, Price and Nolan 2001), and the administration of non‐steroidal anti‐inflammatory drugs such as diclofenac (Graham and others 1997), aspirin (Pollard and others 2001) or carprofen (Price and Nolan 2001), or morphine‐based drugs (Price and Nolan 2001), or alpha 2 ‐agonists such as xylazine (Molony and others 1993a, Grant 2002).…”

Randomised, controlled field trial of two new techniques for the castration and tail docking of lambs less than two days of age

et al. 2004

Two methods to reduce the pain associated with the castration and tail docking of lambs with rubber rings were tested by 10 shepherds, each using 60 housed lambs. In 20 of the lambs the innervation to the scrotum, testes and tail was crushed with a 'Big Nipper' bloodless castrator, and in 20 local anaesthetic (2 per cent lignocaine with adrenaline) was injected with a newly developed high-pressure jet injector under the rubber rings after they had been applied; 10 lambs were given a placebo treatment and 10 were treated by the shepherds' routine elastrator ring procedure. Both new methods significantly decreased the incidence of limb and tail movement by 78 per cent and the time spent by the lambs in abnormal postures, when compared with either the shepherds' routine treatment or the placebo treatment. An experienced observer and most of the shepherds also assessed that the lambs suffered signficantly less pain when treated by the two new methods than when they were treated with rubber rings alone. No detrimental long-term effects of the two new methods were observed. On average the new methods took 68 seconds to apply, compared with 29 seconds for the rubber rings; of the two new methods most shepherds preferred using the pressure jet injector.

“…In rats and humans, suckling (both nutritive and non-nutritive) has been shown to reduce the expression of pain-related behaviours [ 24 , 25 ], as does oral administration of sucrose solution [ 24 , 26 ]. In farm animals, however, neither sucrose infusion nor suckling has been shown to be effective in reducing the pain of castration and/or tail docking in pigs or sheep [ 27 – 29 ]. This may be due to a greater intensity of the pain stimulus experienced in these species, or a different type of pain induced by these management procedures, which seems to inhibit teat-seeking and eliminate any analgesic influence of ingestion of sweet solutions.…”

Ewes Direct Most Maternal Attention towards Lambs that Show the Greatest Pain-Related Behavioural Responses

2015

Although neonatal farm animals are frequently subjected to painful management procedures, the role of maternal behaviour in pain coping, has not been much studied. We investigated whether ewes were able to distinguish between lambs in pain and those that were not, and whether their behaviour altered depending on the severity of lamb pain. Eighty male lambs were allocated to one of 4 pain treatments within 24 hours of birth. Lambs were either handled only (C), bilaterally castrated with tight rubber rings (RR), as for RR but with the application of a Burdizzo clamp immediately proximal to the ring (Combined) or subjected to short scrotum castration (SSC) where the testicles were retained within the abdomen and only the scrotum removed. The behaviour of the ewe, treated lamb and untreated sibling where present (n = 54) were recorded for 30 minutes after treatment. Castration treatment increased the expression of abnormal standing and lying postures, specific pain-related behaviours (head-turning, stamping/kicking, easing quarters, tail wagging) and composite pain scores (P<0.001 for all). The greatest expression of pain-related behaviours was shown by lambs in the RR group, which were the only group to show rolling responses indicative of severe pain, followed by the SSC group. Ewes expressed more licking/sniffing responses to the RR and SSC lambs than towards the Combined and C lambs (P<0.05), and oriented most to RR lambs and least to C lambs (P<0.001). Ewes with two lambs also directed more attention towards the treated than the untreated lamb (P<0.001). The quantity of maternal care directed towards the lamb was positively correlated with the expression of active pain behaviours. The data demonstrate that ewes are able to discriminate between lambs in pain and those that are not, and that their response is increased with a greater severity of pain.
