The relationship between beliefs, attitudes and observed behaviours of abattoir personnel in the pig industry
Contributor(s):: Coleman, G. J., McGregor, M., Hemsworth, P. H., Boyce, J., Dowling, S.
Previous research has indicated that frequent use of aversive pig handling techniques by stockpeople prior to slaughter, in particular the use of an electric prod, results in poorer welfare and reduced meat quality. The aim of this study was to investigate the role of attitudes in the prediction...

Contributor(s):: Jarvis, S., McLean, K. A., Calvert, S. K., Deans, L. A., Chirnside, J., Lawrence, A. B.
The aim of this study was to describe maternal behaviour in the pig and to investigate the effect of endogenous opioids on maternal responsiveness. The behaviour of 16 Large White x Landrace female pigs was recorded around farrowing. The pig's posture and her response when piglets were present at...
The separate and interactive effects of handling and environmental enrichment on the behaviour and welfare of growing pigs
Contributor(s):: Day, J. E. L., Spoolder, H. A. M., Burfoot, A., Chamberlain, H. L., Edwards, S. A.
The aim of this experiment was to determine the interactive effects of handling and environmental enrichment on the behaviour, performance and welfare of the growing/finishing pigs. Groups of pigs were exposed to one of eight treatments arranged in a 2 x 4 factorial design with two levels of...
Time course for the formation and disruption of social organisation in group-housed sows
Contributor(s):: Arey, D. S.
78 Large White x Landrace mixed parity sows were weaned from farrowing crates into groups of 6 and mixed into straw-bedded service pens with individual feeding stalls. Groups were transferred to similar gestation pens after 4 weeks where they remained until farrowing. In experiment 1 (24 sows)...
Tonic immobility and emergence time in pigs - more evidence for behavioural strategies

Transferring results of behavioral research to industry to improve animal welfare on the farm, ranch and the slaughter plant. (International Society for Applied Ethology Special Issue)
Contributor(s):: Grandin, T.
Knowledge obtained from research has been effectively transferred to the agricultural industry in some areas and poorly transferred in others. Knowledge that has been used to create a product such as a pharmaceutical or a device is more likely to be adopted by industry than a behavioral...
Ultrasound observations of fetal movements in the pig: an exploratory study
Contributor(s):: Cohen, S., Mulder, E. J. H., Oord, H. A. van, Jonker, F. H., Weijden, G. C. van der, Taverne, M. A. M.
The feasibility and practical conditions of repeated, non-invasive ultrasound scanning for fetal movements during late gestation in the pig were studied. After a short training period of the sow, good quality recordings of fetal movements were obtained for 60 min using a 3.5 MHz ultrasound...
Care Theory and "caring" systems of agriculture
Contributor(s):: Curry, J. M.
Care Theory is a growing school of ethics that starts with the assumption of the relational nature of human beings. In contrast, the dominant assumption of the autonomous view of human nature has made it difficult to integrate "relational" aspects of reality into the realm of political action...
Editorial: concepts of animal welfare. (Special issue: Concepts of animal welfare)

The behaviour of pigs in lairage in relation to their post-weaning management: results of a postal survey
Contributor(s):: Hunter, E. J., Riches, H. L., Guise, H. J., Penny, R. H. C.
Lairage staff at 11 abattoirs were asked to rate which producers regularly provided pigs which were 'easy' (EH) or 'difficult' (DH) to handle on a scale of 1 (very DH) to 5 (very EH). A postal questionnaire was then sent to the 4 or 5 producers sending the most EH and the 4 or 5 producers sending...

The effect of environmental enrichment on play behaviour in white-lipped peccaries ( Tayassu pecari )
Contributor(s):: Nogueira, S. S. C., Soledade, J. P., Pompeia, S., Nogueira Filho, S. L. G.
Herds of white-lipped peccary (Tayassu pecari) have historically been kept in captivity in order to replace stocks lost to hunting however the lack of knowledge regarding their species-typical behaviour remains an impediment to understanding their captive needs. Environmental enrichment has been...
Effect of housing on in situ postures of gestating gilts
Contributor(s):: Taylor, L., Friend, T., Smith, L. A.
Behaviour of gilts housed in tethered housing, crates, loose housing or dirtlot was video-recorded for 48-h observation periods commencing on days 0, 7 and 63. Lying was the most frequent activity, ranging from 65 to 90
Functional view on udder massage after milk let-down in pigs
Contributor(s):: Spinka, M., Algers, B.
It has been suggested that the function of final udder massage during nursing in pigs is to increase and/or regulate milk transfer. Using the analogy between udder massage and the begging behaviour of nestling birds, this suggestion is re-stated as 6 alternative hypotheses. Final massage may...
Influence of massage during simulated non-nutritive nursings on piglets' milk intake and weight gain
Contributor(s):: Illmann, G., Spinka, M., Stetkova, Z.
Two experiments were conducted with the aim of investigating whether non-nutritive suckling (suckling without milk ejection), when included into a regular rhythm of suckling with milk ejection, affects milk intake and liveweight gain during early lactation in pigs. In experiment 1, when the...
