'subordination style' in pigs? The response of pregnant sows to mixing stress affects their offspring's behaviour and stress reactivity
Contributor(s):: Ison, S. H., D'Eath, R. B., Robson, S. K., Baxter, E. M., Ormandy, E., Douglas, A. J., Russell, J. A., Lawrence, A. B., Jarvis, S.
In various mammals stress during gestation can result in long term effects on the behaviour and physiology of the offspring. The aims of this study were (i) to characterise individual variation among primiparous sows (gilts) in their behavioural and physiological response to a commercially...
A combination of behavioral and physiological indicators for assessing pig welfare on the farm
Contributor(s):: Candiani, D., Salamano, G., Mellia, E., Doglione, L., Bruno, R., Toussaint, M., Gruys, E.
The purpose of this research was to identify pig welfare indicators that could help in recognizing stressful practices on farm. The study evaluated behavioral and physiological indicators (cortisol and negative acute phase proteins) in 2 groups of 20 female pigs 4 months old after a 48-hr...

A flooring comparison: the impact of rubber mats on the health, behavior, and welfare of group-housed sows at breeding
Contributor(s):: Elmore, M. R. P., Garner, J. P., Johnson, A. K., Richert, B. T., Pajor, E. A.
Comfortable flooring may impact many aspects of an animal's welfare, including lying behavior, an animal's ability to change postures, and incidence of lameness and lesions. Therefore, we hypothesized that the addition of rubber mats to stalls of group pens would improve sow health, comfort and...
A meta-analysis of the combined effect of housing and environmental enrichment characteristics on the behaviour and performance of pigs
Contributor(s):: Averos, X., Brossard, L., Dourmad, J. Y., Greef, K. H. de, Edge, H. L., Edwards, S. A., Meunier-Salaun, M. C.
To quantify the combined effect of housing conditions and environmental enrichment on the behaviour and performance of pigs, a meta-analysis was performed using information from 45 experiments in 42 published manuscripts. Multiple regression models were applied to evaluate the effects of space...

A multidisciplinary approach to assess the welfare of weaned pigs during transport at three space allowances
Contributor(s):: Sutherland, M. A., Bryer, P. J., Davis, B. L., McGlone, J. J.
Transport can be a stressful experience for pigs, especially in pigs simultaneously experiencing weaning stress. The objective of this study was to use a multidisciplinary approach to assess the welfare of weaned pigs during transport at 3 space allowances. A commercial semitrailer, fitted with...
A note on genetic parameters of gilt responses to humans
Contributor(s):: Hellbrugge, B., Tolle, K. H., Presuhn, U., Krieter, J.
In this study, a response test towards a stockperson was evaluated for improved maternal behaviour and increased piglet survival. Records were available from 638 German Landrace gilts with 860 observations tested for the response to an observer in the familiar environment of the mating centre....
A novel method for lifting weanling research pigs
Contributor(s):: Minch, H. N., Berghaus, R. D., Harvey, S. B., Reeves, D. E., Crowell-Davis, S. L.
It is possible to modify lifting techniques in small laboratory pigs to evoke less of a fear response, strengthen the human-animal bond, and improve welfare. The authors hypothesized that recently weaned pigs lifted with a ventral (belly) scoop method would show less fear of new humans and less...
A preliminary study of the effects of individual response to challenge tests and stress induced by humans on learning performance of weaned piglets (Sus scrofa)
Contributor(s):: Brajon, S., Laforest, J. P., Schmitt, O., Devillers, N.
This study investigated whether individual behavioural characteristics of piglets and stress induced by experience with humans can influence learning performance. After weaning, piglets received a chronic experience with humans to modulate their emotional state: rough (ROU), gentle (GEN), or...
A review of environmental enrichment for pigs housed in intensive housing systems
Contributor(s):: de Weerd, H. A. van, Day, J. E. L.
This paper critically reviews the literature concerning environmental enrichment for weaner, grower and finisher pigs housed in intensive (indoor) production systems. The thesis of our review is that successful enrichment should meet four criteria of success: (1) it should increase...
A review of the welfare consequences of surgical castration in piglets and the evaluation of non-surgical methods

Aggressive behavior in two different group-housing systems for pregnant sows
Contributor(s):: Chapinal, N., Ruiz-de-la-Torre, J. L., Cerisuelo, A., Gasa, J., Baucells, M. D., Manteca, X.
The study housed 120 pregnant sows from Day 29 of pregnancy to 1 week before parturition either in groups of 10 with trickle feeding (TRICKLE) or in groups of 20 with an unprotected electronic sow feeding (FITMIX). The study recorded aggressive interaction on 11 nonconsecutive days. Frequency of...
Altered aggression in different sized groups of crayfish supports a dynamic social behaviour model
Contributor(s):: Patullo, B. W., Baird, H. P., Macmillan, D. L.
Living in groups with conspecifics can increase an animal's fitness in the wild. A social environment may also be imposed by commercial farming industries. One important measure of competition and group dynamics is the level of aggressive interaction. This can also influence the level of damage...
Alternative housing for sows and litters 1. Effects of sow-controlled housing on responses to weaning
Contributor(s):: Pajor, E. A., Weary, D. M., Fraser, D., Kramer, D. L.
A sow-controlled housing system and its affects on production and welfare problems resulting from the abrupt separation of piglets from sows at weaning was investigated. 44 sows and litters were housed during lactation in either a 'confined' pen where the sow and litter were kept together, or a...
An initial investigation into the effects of isolation and enrichment on the welfare of laboratory pigs housed in the PigTurn system, assessed using tear staining, behaviour, physiology and haematology
Contributor(s):: DeBoer, S. P., Garner, J. P., McCain, R. R., Lay, D. C., Jr., Eicher, S. D., Marchant-Forde, J. N.
In some parts of the world, the laboratory pig ( Sus scrofa) is often housed in individual, sterile housing which may impose stress. Our objectives were to determine the effects of isolation and enrichment on pigs housed within the PigTurn - a novel penning system with automated blood sampling -...

Contributor(s):: Dalmau, A., Nande, A., Vieira-Pinto, M., Zamprogna, S., Martino, G. di, Ribas, J. C. R., Costa, M. P. da, Halinen-Elemo, K., Velarde, A.
The objective of the present study is to assess the variability of the measures used in the welfare quality (WQ) protocol for pigs among slaughterhouses in five different countries and to propose alarm and critical thresholds for the calculation of scores for future development of an animal...
Are domestic pigs (Sus scrofa domestica) able to use complex human-given cues to find a hidden reward?
Contributor(s):: Nawroth, C., Ebersbach, M., Borell, E. von
Understanding human-animal interactions in livestock production systems is crucial for improving animal welfare. It is therefore of general interest to investigate how livestock animals obtain information from humans. By using an object-choice paradigm, we investigated whether domestic pigs (Sus...
Artificial illumination reduces bait-take by small rainforest mammals
Contributor(s):: Bengsen, A. J., Leung, L. K. P., Lapidge, S. J., Gordon, I. J.
Small mammals often moderate their foraging behaviour in response to cues indicating a high local predation risk. We assessed the ability of cues associated with a high predation risk to reduce the consumption of bait by non-target small mammal species in a tropical rainforest, without inhibiting...
