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...

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...

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...

The effects of age and sex on pain sensitivity in young lambs
Contributor(s):: Guesgen, Mirjam J., Beausoleil, Ngaio J., Minot, Edward O., Stewart, Mairi, Jones, Geoff, Stafford, Kevin J.
Lambs routinely undergo painful husbandry procedures including ear tagging, tail docking and castration. Pain early in life is important because it can compromise lamb welfare. Studies of altricial species, such as rodents and humans, suggest that baseline pain sensitivity varies with age and...

Effect of rectal or intravenous tramadol on the incidence of pain-related behaviour after disbudding calves with caustic paste
Contributor(s):: Braz, Maria, Carreira, Maria, Carolino, Nuno, Rodrigues, Tania, Stilwell, George
To evaluate the efficacy of tramadol (suppositories or intravenous) in alleviating pain after caustic paste disbudding, two behaviour-assessing methods were used during the first hour post-disbudding: the objective recording of four pain-related behaviours and the subjective scoring pain on a...

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...

Castration induced pain in pigs and other livestock
Contributor(s):: Rault, Jean-Loup, Lay, Donald C., Marchant-Forde, Jeremy N.
Castration of male livestock being reared for meat has long been practiced, to prevent unwanted breeding, make management and handling easier, and to improve meat quality. However, castration is a painful procedure for the animal and has increasingly come under scrutiny from animal welfare...

Behavioural changes following intraperitoneal vaccination in Atlantic salmon (Salmo salar)
Contributor(s):: Bjørge, Mette Helen, Nordgreen, Janicke, Janczak, Andrew Michael, Poppe, Trygve, 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. Previous studies have looked at pathological change and feeding behaviour in large groups of fish....

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...
