Lack of evidence for stress being caused to pigs by witnessing the slaughter of conspecifics
Contributor(s):: Anil, M. H., McKinstry, J. L., Field, M., Rodway, R. G.
15 catheterized pigs (Duroc x Large White) of mixed sex of between 35 and 65 kg body weight were allowed to see the stunning and sticking (exsanguination) of pigs in a nearby pen. Each witness pig was placed in a hammock giving it a full view of another pen in which 2 other pigs were put. One of...

Neonate rats demonstrate high levels of retention for odour preference when a substantially reduced training trial of two minutes is used
Contributor(s):: Ogeil, R. P., Edwards, T. M.
Neonate rats have played an important and unique role within the memory literature. Specifically, they are relatively naive to experience, can be trained in an ethologically-valid way, using a single trial, which is not aversive and can demonstrate retention for at least 24 h, post-training. As...

On-farm monitoring of pig welfare by assessment of housing, management, health records and plasma haptoglobin
Contributor(s):: Geers, R., Petersen, B., Huysmans, K., Knura-Deszczka, S., Becker, M. de, Gymnich, S., Henot, D., Hiss, S., Sauerwein, H.
Current research is focusing on integrated longitudinal assessment of animal welfare at the farm-level. Housing and management systems may influence pain, discomfort, fear, hunger and abnormal behaviour of farm animals. Poor health records and increased levels of haptoglobin have been shown to...
Oral administration of a 12% sucrose solution did not decrease behavioural indicators of distress in piglets undergoing tail docking, teeth clipping and ear notching
Contributor(s):: Rand, J. S., Noonan, G. J., Priest, J., Ainscow, J., Blackshaw, J. K.
Sucrose has been shown to attenuate the behavioural response to painful procedures in human infants undergoing circumcision or blood collection via heelstick. Sucrose has also been found to have a behaviour-modifying effect in neonatal rats exposed to a hot plate. The effect was abolished in...
Peri-natal environmental effects on maternal behaviour, pituitary and adrenal activation, and the progress of parturition in the primiparous sow
Contributor(s):: Jarvis, S., Reed, B. T., Lawrence, A. B., Calvert, S. K., Stevenson, J.
Maternal behaviour in free-ranging sows is normally performed in an isolated nest that the sow has built during the pre-parturient period. Consequently there is much concern over the use of restrictive farrowing crates, in which manipulable substrates are often not provided, for parturient sows...

Reactions of cattle to head-restraint at stunning: a practical dilemma
Contributor(s):: Ewbank, R., Parker, M. J., Mason, C. W.
The behavioural reactions and blood cortisol levels of cattle stunned using a penetrating captive-bolt pistol whilst standing free in a stunning box were compared with those obtained from cattle similarly stunned but with their heads held in a hydraulically operated chin-lift type of head...
Refinement of gerbil housing and husbandry in the laboratory
Contributor(s):: Waiblinger, E., Konig, B.
Mongolian gerbils (Meriones unguiculatus) are a widely used model species in parasitology and epilepsy research. Under standard laboratory housing conditions gerbils develop stereotypic digging, a behavioural abnormality, which is caused by the lack of a burrow in the laboratory cage. Here, we...

Salivary IgA: a possible stress marker in dogs
Contributor(s):: Skandakumar, S., Stodulski, G., Hau, J.
The authors analysed groups of police and army dogs undergoing physical and temperamental training. Salivary IgA (S-IgA) levels were measured by rocket immunoelectrophoresis. Behavioural assessment was carried out and cortisol levels in saliva were measured by ELISA. A significant negative...
Socialization and stress in cats ( Felis silvestris catus ) housed singly and in groups in animal shelters
Contributor(s):: Kessler, M. R., Turner, D. C.
This study investigated whether the socialization of the cat towards conspecifics and people influences adaptation to single- and group-housing conditions. Socialization towards conspecifics and people was determined in 169 rescued cats using 2 behavioural tests and a socialization questionnaire...
Stress and adaptation of cats ( Felis silvestris catus ) housed singly, in pairs and in groups in boarding catteries
The development of stress in 140 boarding cats during a two-week stay under single-, pair- and group-housing conditions in a boarding cattery was investigated and compared with the stress levels of 45 control cats which had been at the animal shelter for several weeks. Signs of stress were...

Stress hormone responses of sheep to food and water deprivation at high and low ambient temperatures
Contributor(s):: Parrott, R. F., Lloyd, D. M., Goode, J. A.
Eight Clun Forest wethers were used to study the effects of feed and/or water deprivation at different ambient temperatures (7 or 35 degrees C) on stress hormone release. Blood samples were taken from catheterized animals at the start and at 6 h intervals during 48 h tests in an environmental...
Stress in wild-caught Eurasian otters ( Lutra lutra ): effects of a long-acting neuroleptic and time in captivity
Contributor(s):: Fernandez-Moran, J., Saavedra, D., Ruiz de la Torre, J. L., Manteca-Vilanova, X.
As part of a translocation project, 28 Eurasian otters (Lutra lutra) were captured from the wild and transported to the Barcelona Zoo for veterinary evaluation, quarantine and intraperitoneal implantation of telemetry devices. Eleven animals were injected with the long-acting neuroleptic (LAN)...

Successful group housing of wild-caught brushtail possums ( Trichosurus vulpecula )
Contributor(s):: McLeod, B. J., Thompson, E. G., Crawford, J. L., Shackell, G. H.
The husbandry of the common brushtail possum colony in the Invermay Agricultural Centre, New Zealand is described. Emphasis has been placed on the maintenance of social interaction between possums and their ability to exhibit instinctive behaviour patterns. It is suggested that, under these...
The effect of contact with conspecifics and humans on calves' behaviour and stress responses
Contributor(s):: Raussi, S., Lensink, B. J., Boissy, A., Pyykkonen, M., Veissier, I.
In this study, we analysed the effects of social and human contact on calves' behaviour and stress responses. We also measured the effect of this contact on calves' reactions to novel conspecifics and novel humans. Sixty-four calves were housed either alone or in pairs and received either minimal...
