  1. Chewable materials before weaning reduce tail biting in growing pigs

    Contributor(s):: Telkänranta, Helena, Swan, Kirsi, Hirvonen, Heikki, Valros, Anna

    Tail biting in pigs is a multi-factorial problem, and the early rearing environment has been proposed as a potential previously unidentified factor. The aim of this study was to test whether access to chewable material from birth to weaning reduces later tail biting. Undocked litters of 59 sows...

  2. Tail biting in fattening pigs: Associations between frequency of tail biting and other abnormal behaviours

    Contributor(s):: Brunberg, Emma, Wallenbeck, Anna, Keeling, Linda J.

    This study investigated the association between tail biting (TB) and other abnormal behaviours in a group of non-tail docked pigs. Behavioural data were collected from 742 pigs housed on a commercial farm. The prevalence of performed and received TB, belly nosing, bar biting, ear biting and...

  3. Stability of social hierarchy in growing female pigs and pregnant sows

    Contributor(s):: Parent, Jean-Philippe, Meunier-Salaün, Marie-Christine, Vasseur, Elsa, Bergeron, Renée

    Conflicting results between dominance tests and repetitions of these tests over time in pigs may result from a lack of stability of their social hierarchy. The objectives of this study were to compare five methods to measure social hierarchy and to examine the stability of test results over time...

  4. Review of wallowing in pigs: Description of the behaviour and its motivational basis

    Contributor(s):: Bracke, M. B. M.

    Wallowing, i.e. coating the body surface with mud, is a natural behaviour of pigs, commonly observed in feral pigs and wild boar, but rarely provided for in current housing systems for domestic pigs. Furthermore, in welfare science the subject has not been receiving much attention. This paper...

  5. Relationship between backtest and coping styles in pigs

    Contributor(s):: Spake, Jessica R., Gray, Kent A., Cassady, Joseph P.

    The objective of this study was to examine relationships between behaviors in three different standard tests of temperament in pigs, Sus scrofa. For the backtest, pigs (n=575) were placed in the supine position for 60s. Each pig was tested twice. Amount of time struggling and number of struggle...

  6. Qualitative Behavioural Assessment of emotionality in pigs

    Contributor(s):: Rutherford, Kenneth M. D., Donald, Ramona D., Lawrence, Alistair B., Wemelsfelder, Françoise

    Scientific assessment of affective states in animals is challenging but vital for animal welfare studies. One possible approach is Qualitative Behavioural Assessment (QBA), a ‘whole animal’ methodology which integrates information from multiple behavioural signals and styles of behavioural...

  7. Peat as environmental enrichment for piglets: The effect on behaviour, skin lesions and production results

    Contributor(s):: Vanheukelom, Valerie, Driessen, Bert, Maenhout, Daniël, Geers, Rony

    The aim of this study was to examine whether the provision of small amounts of peat to piglets would influence behaviour and production. At approximately 5 days of age, nine litters received a tray of peat as enrichment, while nine others did not. All piglets had access to solid feed, which was...

  8. A longitudinal study of the effects of providing straw at different stages of life on tail-biting and other behaviour in commercially housed pigs

    Contributor(s):: Statham, Poppy, Green, Laura, Mendl, Michael

    Tail-biting (TB) is a welfare concern. Recent studies indicate that early provision of straw may help prevent TB, however, many of these studies were carried out on small groups of pigs and may have limited applicability to commercial farms. The effect of providing straw at different stages of...

  9. The long and short of it: A review of tail docking in farm animals

    Contributor(s):: Sutherland, Mhairi A., Tucker, Cassandra B.

    Tail docking involves amputating a portion of the tail for a variety of reasons. We review the scientific evidence for the rationale for tail docking, a description of the different methods used, the pain response to the procedure and the effectiveness of pain alleviation, and, finally, the...

  10. Juvenile pigs use simple geometric 2D shapes but not portrait photographs of conspecifics as visual discriminative stimuli

    Contributor(s):: Gieling, Elise T., Musschenga, Maartje A., Nordquist, Rebecca E., van der Staay, F. Josef

    Several animals living in social groups, such as monkeys, cows and sheep, have been shown to use facial discrimination for social recognition. Whether pigs can discriminate between faces of conspecifics purely based on visual stimuli provided by 2D portrait photographs, has not yet been...

  11. Investigations on feed intake and social behaviour of fattening pigs fed at an electronic feeding station

    Contributor(s):: Hoy, Steffen, Schamun, Sonja, Weirich, Carmen

    For the study from a total of 679 female pigs kept in a progeny test station in 64 groups mostly with 12 pigs each, the data from all visits at an electronic feeding station (EFS) were analysed. In 93 pigs (8 groups) all agonistic interactions at the EFS were recorded in continuous observations...

  12. Investigation of distances covered by fattening pigs measured with VideoMotionTracker®

    Contributor(s):: Brendle, Julia, Hoy, Steffen

    The investigation was carried out with altogether 144 pigs kept in groups of 6 or 12. Every pen was equipped with perforated floor. Water and the in-house compound feed with different elements depending on the fattening period were available ad libitum during the whole fattening period. At the...

  13. Influence of origin litter on social rank, agonistic behaviour and growth performance of piglets after weaning

    Contributor(s):: Fels, Michaela, Hoy, Steffen, Hartung, Jörg

    In pig production, mixing of piglets after weaning is a common management practice often leading to severe fighting aimed at establishing a social hierarchy. The intention of our study was to investigate whether social rank of piglets obtained by fighting within 3 days after weaning and mixing...

  14. Getting around social status: Motivation and enrichment use of dominant and subordinate sows in a group setting

    Contributor(s):: Elmore, Monica Renee Pittman, Garner, Joseph Paul, Johnson, Anna Kerr, Kirkden, Richard D., Richert, Brian Thomas, Pajor, Edmond Anthony

    Gestating sow motivation for enriched environments is unknown, but is essential knowledge for developing housing that addresses animal welfare concerns. This study investigated whether the motivation of gestating sows for access to an enriched group pen (containing a rubber mat, straw, compost,...

  15. Flavour preference acquired via a beverage-induced conditioning and its transposition to solid food: Sucrose but not maltodextrin or saccharin induced significant flavour preferences in pigs

    Contributor(s):: Clouard, Caroline, Chataignier, Mathieu, Meunier-Salaün, Marie-Christine, Val-Laillet, David

    When exposed to novel food during food transitions, growing pigs often elicit a neophobic response that is responsible for decreased food consumption. Flavour preference conditioning may represent an interesting way to reduce neophobia and improve food intake in growing pigs. The present series...

  16. Feeding strategy in group-housed growing pigs of four different breeds

    Contributor(s):: Fernández, Josep, Fàbrega, Emma, Soler, Joaquim, Tibau, Joan, Ruiz, José Luis, Puigvert, Xavier, Manteca, Xavier

    Feeding strategy was studied in 205 growing boars in two blocks of 116 and 89 pigs of four breeds (Large White, Landrace, Duroc and Pietrain) respectively. Pigs were housed in groups of 12–14 individuals, with a single breed in each group. Feeding patterns were recorded with a computerized feed...

  17. Evidence for residence-induced enhancement of aggressiveness in the non-territorial pig

    Contributor(s):: Turner, Simon P., Farnworth, Mark J., Mendl, Mike, Erhard, Hans W., Lawrence, Alistair B.

    Wild pigs (Sus scrofa) are only territorial during the peri-parturient period and when young compete for access to teats. In other species, territorial defence is affected by contextual factors including resource quality. Territoriality could be stimulated in species such as pigs by artificial...

  18. The effects of sensory functional ingredients on food preferences, intake and weight gain in juvenile pigs

    Contributor(s):: Clouard, Caroline, Meunier-Salaün, Marie-Christine, Val-Laillet, David

    When exposed to a novel diet during food transition, pigs often decrease voluntarily their food intake, which can lead to impaired growth. The aim of the present study was to test the palatability of eight unknown food additives (mixture of various essential oils and other plant extracts) and to...

  19. Effects of previous housing system on agonistic behaviors of growing pigs at mixing

    Contributor(s):: Li, Yuzhi, Wang, Lihua

    Previous studies indicated that rearing environment in early life affects behavioral development, which consequently modifies behavioral response of pigs to stressful environments in later stages of the production. A study was conducted to investigate effects of group-farrowing system on behavior...

  20. Effect of marginal environmental and social enrichment during rearing on pigs’ reactions to novelty, conspecifics and handling

    Contributor(s):: Tönepöhl, Björn, Appel, Anne K., Welp, Stephan, Voß, Barbara, König von Borstel, Uta, Gauly, Matthias

    The rearing environment of farmed animals can affect their behaviour when handled, and therefore needs to be taken into account when selecting for traits such as docility. Therefore, 126 German Landrace and Pietrain×German Landrace pigs were reared in two different production environments (barren...
