Effect of increasing temperature on space requirements of group housed finishing pigs
Contributor(s):: Spoolder, Hans A. M., Aarnink, André A. J., Vermeer, Herman M., van Riel, Johan, Edwards, Sandra A.
For groups of pigs to cope adequately with their housing conditions they need sufficient static space (occupied by the body of the pig), activity space (for movement between different functional areas and behaviours relating to these) and interaction space (for appropriate social behaviour)....
Do pigs distinguish between situations of different emotional valences during anticipation?
Contributor(s):: Imfeld-Mueller, Sabrina, Van Wezemael, Lea, Stauffacher, Markus, Gygax, Lorenz, Hillmann, Edna
An animal's welfare is strongly affected by its emotional state. Thus, many recent studies have focused on measuring the emotional states and responses of animals. However, there is still a lack of knowledge on assessing positive emotions, although it is widely accepted that positive emotions are...
Differing results for motivation tests and measures of resource use: The value of environmental enrichment to gestating sows housed in stalls
Contributor(s):: Elmore, Monica R. P., Garner, Joseph P., Johnson, Anna K., Kirkden, Richard D., Patterson-Kane, Emily G., Richert, Brian T., Pajor, Edmond A.
Sows are often housed in barren stalls during breeding and/or gestation. Environmental enrichment may improve sow welfare; however, the value of specific enrichments to sows is largely unknown. Our aim was to compare the motivation of gestating sows (32, n=8/treatment) housed in stalls...
Coping personality type and environmental enrichment affect aggression at weaning in pigs
Contributor(s):: Melotti, Luca, Oostindjer, Marije, Bolhuis, J. Elizabeth, Held, Suzanne, Mendl, Michael
This study investigated the effects of different environmental treatments and personality types on aggression at mixing of newly weaned domestic piglets. From birth to weaning, 16 litters were housed with their dams in either barren (B) or larger, substrate-enriched (E) environments. At 15 days...
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...
Can sow pre-lying communication or good piglet condition prevent piglets from getting crushed?
Contributor(s):: Melišová, Michala, Illmann, Gudrun, Andersen, Inger Lise, Vasdal, Guro, Haman, Jiří
This study focused on the impact of sow–piglet communication during pre-lying behaviour and piglet condition on piglet location before the sow was lying down and on the incidence of piglet crushing. Eighteen loose-housed, Yorkshire×Norwegian Landrace sows and their litters were studied on Day 1...
Behavior, production results and meat quality of intact boars and gilts housed in unmixed groups: A comparative study
Contributor(s):: Vanheukelom, Valerie, Van Beirendonck, Sanne, Van Thielen, Jos, Driessen, Bert
Surgical castration of male pigs is a practice that will probably be abandoned in Europe in the future because of general protest against pain in animals and a growing concern on (farm) animal welfare. Rearing entire males will therefore inevitably be integrated in the pig sector. In the present...
Assessment of animal welfare through behavioural parameters in Iberian pigs in intensive and extensive conditions
Contributor(s):: Temple, Déborah, Manteca, Xavier, Velarde, Antonio, Dalmau, Antoni
Behaviour is a significant component of well-being and should be properly considered in a pig welfare assessment. However, interpretation of variations in behaviour is usually not straightforward, especially when dealing with animals housed and managed in a variety of systems. The fourth...
Anticipation of a food ball increases short-term activity levels in growing pigs
Contributor(s):: Imfeld-Mueller, Sabrina, Hillmann, Edna
Analogous to the way in which repeated episodes of stress can lead to a negative emotional state, it is possible that repeated positive emotions could lead to a positive emotional state. Positive emotions can be induced by providing enrichment or by successfully coping with cognitive challenges....
Agonistic behaviour after mixing in pigs under commercial farm conditions
Contributor(s):: Stukenborg, Andreas, Traulsen, Imke, Puppe, Birger, Presuhn, Ulrich, Krieter, Joachim
The aim of the study was to investigate agonistic behaviour of pigs after regrouping pigs under commercial sow farm conditions. The behavioural patterns were observed over a 48-h period, directly after weaning (PIG-28; n=647) and 40 days later (growing pigs, PIG-68; n=224). Agonistic interactions...
City of Beasts: How Animals Shaped Georgian London. Manchester: Manchester University Press, 2019. xviii + 310pp. 34 figures. Bibliography. £25.00 hbk. £30.00 ebk
Contributor(s):: Taverner, Charlie
Farm animals populate the next two sections: the cows and pigs reared within the built-up area, and the cattle and sheep driven into the heart of the city to be slaughtered. A recurrent theme of the book is the way in which urban growth actually increased interactions between animals and humans...
Broadcasting human voice to piglets (sus scrofa domestica) modifies their behavioural reaction to human presence in the home pen and in arena tests

Longitudinal effects of human supremacy beliefs and vegetarianism threat on moral exclusion (vs. inclusion) of animals
Contributor(s):: Leite, Ana C., Dhont, Kristof, Hodson, Gordon
Contributor(s):: Czycholl, Irena, Menke, Stina, Straßburg, Carolin, Krieter, Joachim
Behavioural tests might have the potential to evaluate certain aspects of welfare such as emotional state or the human-animal relationship. However, reliability assessments of these tests are rare. Therefore, in this study, different behavioural tests for growing pigs were assessed regarding...
Suckling behaviour and health parameters of sows and piglets in free-farrowing pens
Contributor(s):: Lohmeier, R. Y., Gimberg-Henrici, C. G. E., Burfeind, O., Krieter, J.
The aim of the present study was to investigate the effect of free-farrowing pens and farrowing crates on the health parameters and the suckling behaviour of sows and their piglets, which were housed in farrowing crates (FC; n = 127) and in free-farrowing pens (FP; n = 121). All sows were...
Is tail biting in growing pigs reduced by a prolonged suckling period?
Contributor(s):: Naya, Ashley, Traulsen, Imke, Gertz, Marvin, Hasler, Mario, Burfeind, Onno, große Beilage, Elisabeth, Krieter, Joachim
It was the aim of the study to investigate the effect of a prolonged suckling period and group housing before weaning on tail biting in undocked nursery pigs. To do this, experiments with three treatment groups were investigated. In the first group, pigs were conventionally housed in pens with...
Artificial rearing affects piglets pre-weaning behaviour, welfare and growth performance
Contributor(s):: Schmitt, Océane, O'Driscoll, Keelin, Boyle, Laura A., Baxter, Emma M.
One strategy adopted on farms to deal with managing large litters involves removing piglets from their mothers at seven days old to be reared in specialised accommodation with milk replacer. Effects on piglet behaviour, growth and some aspects of welfare were evaluated in this study by comparing...
Early socialisation as a strategy to increase piglets’ social skills in intensive farming conditions
Contributor(s):: Salazar, Laura C., Ko, Heng-Lun, Yang, Chung-Hsuan, Llonch, Lourdes, Manteca, Xavier, Camerlink, Irene, Llonch, Pol
Socialisation is a process in which animals interact with unfamiliar conspecifics, that allows them to develop their social abilities. Socialisation has been proposed as a method in pig husbandry to increase piglets’ social skills and reduce conspecific aggression, which is a major welfare issue...
A comparison of inferential analysis methods for multilevel studies: Implications for drawing conclusions in animal welfare science
Contributor(s):: Stevens, Kara N., Asher, Lucy, Griffin, Kym, Friel, Mary, O'Connell, Niamh, Collins, Lisa M.
Investigations comparing the behaviour and welfare of animals in different environments have led to mixed and often conflicting results. These could arise from genuine differences in welfare, poor validity of indicators, low statistical power, publication bias, or inappropriate statistical...
