  1. The effect of two different farrowing systems on sow behaviour, and piglet behaviour, mortality and growth

    Contributor(s):: Loftus, Loni, Bell, Grace, Padmore, Emily, Atkinson, Samantha, Henworth, Andrew, Hoyle, Mark

    Farrowing crates have traditionally been used to reduce occurrence of piglet mortality as a result of sow crushing. However the utilisation of traditional farrowing crates has been suggested to contribute to negative welfare for both the sow and piglets. This study compared mortality rates,...

  3. Prepartum nest-building has an impact on postpartum nursing performance and maternal behaviour in early lactating sows

    | Contributor(s):: Yun, Jinhyeon, Swan, Kirsi-Marja, Farmer, Chantal, Oliviero, Claudio, Peltoniemi, Olli, Valros, Anna

    The effects of facilitating prepartum nest-building (NB) behaviour, by providing abundant nesting materials, on postpartum maternal characteristics in early lactating sows were evaluated. A total of 35 sows, approximately seven days before the expected parturition date, were housed in: (1) CRATE...

  4. Nest building and posture changes and activity budget of gilts housed in pens and crates

    | Contributor(s):: Andersen, Inger Lise, Vasdal, Guro, Pedersen, Lene Juul

    The aim of the present work was to study nest building, posture changes and the overall activity budget of gilts in pens vs. crates. Twenty-three HB gilts (high piglet survival day 5) and 21 LB gilts (low piglet survival day 5) were video recorded from day 110 in pregnancy to four days after...

  5. The effects of the light regimen imposed during lactation on the performance and behaviour of sows and their litters

    | Contributor(s):: Simitzis, Panagiotis E., Veis, Dimitrios, Demiris, Nikos, Charismiadou, Maria A., Ayoutanti, Anna, Deligeorgis, Stelios G.

    The objective of the present study was to highlight the possible effects of an extended photoperiod throughout lactation on the performance and behaviour of sows and their piglets. Sows were randomly assigned to two light regimens: (1) standard (n=12) consisting of 8h of light (0700–1500) daily...

  6. The effect of ketoprofen on post-partum behaviour in sows

    | Contributor(s):: Viitasaari, Elina, Raekallio, Marja, Heinonen, Mari, Valros, Anna, Peltoniemi, Olli, Hänninen, Laura

    A randomized, double-blinded, placebo controlled trial was conducted in order to estimate pain-related behavioural changes of sows in early lactation. Ketoprofen (KET) was used (3mg/kg BW) intramuscularly for three consecutive days post-partum (p.p.) on 19 sows. Nineteen sows were used as a...

  7. 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...

  8. Impact of social stress during gestation and environmental enrichment during lactation on the maternal behavior of sows

    | Contributor(s):: Ringgenberg, Nadine, Bergeron, Renée, Meunier-Salaün, Marie-Christine, Devillers, Nicolas

    The impact of a social stress in gestation and an enriched pen in lactation on components of sow maternal behavior was studied in a 2×2 factorial experiment. At breeding, 41 sows were assigned to a social mixing stress treatment (T) during mid-gestation or a control group (C). During lactation,...

  9. Extensive infanticide in enclosed European wild boars (Sus scrofa)

    | Contributor(s):: Andersson, Annelie, Valros, Anna, Rombin, Johan, Jensen, Per

    Infanticidal behaviour, behaviour with wide welfare implications, is wide-spread among animals of various taxonomic groups, but has not previously been systematically studied in European wild boars, which are commonly kept in enclosures in Sweden and Finland for meat and recreation hunting. We...

  10. 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...

  11. The effect of feed trough position on choice of defecation area in farrowing pens by loose sows

    | Contributor(s):: Andersen, Heidi Mai-Lis, Pedersen, Lene Juul

    The primary aim of the present study was to investigate how the feed trough position affects the sow's choice of defecation area in a loose house farrowing pen. The eliminative behaviour of 24 1st parity sows was studied in a cross-over design. The feed trough and the water were positioned either...

  12. Impact of social stress during gestation and environmental enrichment during lactation on the maternal behavior of sows

    | Contributor(s):: Ringgenberg, Nadine, Bergeron, Renée, Meunier-Salaün, Marie-Christine, Devillers, Nicolas

    The impact of a social stress in gestation and an enriched pen in lactation on components of sow maternal behavior was studied in a 2×2 factorial experiment. At breeding, 41 sows were assigned to a social mixing stress treatment (T) during mid-gestation or a control group (C). During lactation,...

  13. The course of parturition in two sow genotypes and two hut designs under free-range conditions

    | Contributor(s):: Schild, S. L. A., Rangstrup-Christensen, L., Thorsen, C. K., Bonde, M. K., Pedersen, L. J.

    High piglet mortality remains a major challenge in outdoor pig production. The use of hyper prolific sow genotypes giving birth to large litters may prolong parturition and cause parturition-related problems under outdoor conditions where birth assistance cannot easily be provided. Therefore, the...

  14. 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...

  15. The effect of group-housing with free-farrowing pens on reproductive traits and the behaviour of low-risk and high-risk crushing sows

    | Contributor(s):: Grimberg-Henrici, C. G. E., Büttner, K., Lohmeier, R. Y., Burfeind, O., Krieter, J.

    Free-farrowing systems and group-housing systems for lactating sows are sensitive systems and require an optimal interaction of different environmental factors to be successful. The aim of the present study was to compare sows’ reproductive traits during lactation in two group-housing systems...

  16. Confinement of sows 24h before expected farrowing affects the performance of nest building behaviours but not progress of parturition

    | Contributor(s):: Hansen, Christian F., Hales, Janni, Weber, Pernille M., Edwards, Sandra A., Moustsen, Vivi A.

    The effects of confinement prior to farrowing on the performance of nest building behaviour and progress of parturition were investigated using hyper prolific sows. Forty first parity and 41second/third parity sows were allocated to one of two treatments: loose housed (40) or confined (41). All...

  17. Comparison of nest-building materials in farrowing crates

    | Contributor(s):: Swan, Kirsi-Marja, Peltoniemi, Olli Aarno Tapio, Munsterhjelm, Camilla, Valros, Anna

    The farrowing crate restricts the performance of natural behaviour of sows, such as nest building, by limiting both sow movement and use of suitable nest-building materials. Restriction leads to short- and long lasting changes in farrowing, maternal behaviour and lactation. We investigated the...

  18. Behaviour of gilts before and at parturition after intensified human-animal contact, training to be driven, or exposure to a farrowing pen

    | Contributor(s):: Brötje, Anska, Gygax, Lorenz, Hillmann, Edna, Wechsler, Beat

    During rearing and until first insemination, housing conditions of gilts are relatively constant and the few human-animal interactions negative. Around first parturition, however, gilts experience intensified contact with stockpersons and are subjected to new management procedures such as being...

  19. Management strategies in farrowing house to improve piglet pre-weaning survival and growth

    | Contributor(s):: Vila, R. M., Tummaruk, P.

    Post-partum and lactation are the most complex periods in the swine production chain. Newborn pigs are highly vulnerable due to relatively low body weight at birth and physiological immaturity. Most of the management strategies performed in farrowing houses are oriented to ensure a proper level...

  20. Observations of sows and piglets housed in farrowing pens with temporary crating or farrowing crates on a commercial farm

    | Contributor(s):: Chidgey, Kirsty L., Morel, Patrick C. H., Stafford, Kevin J., Barugh, Ian W.

    Alternatives to farrowing crates have been developed to improve sow welfare. These alternative farrowing systems have been designed to provide more space, allowing sows greater freedom of movement during lactation. This experiment was part of a larger study comparing sow and piglet performance...
