    Contributor(s):: Caviola, Lucius, Kahane, Guy, Everett, Jim A. C., Teperman, Elliot, Savulescu, Julian, Faber, Nadira S.

  3. A review of video-based pig behavior recognition

    Contributor(s):: Yang, Qiumei, Xiao, Deqin

    Video surveillance technology has been applied in many farms and a large amount of video data has been generated. Extracting valuable information about the pig industry from video data is a challenging problem. Pig behavior recognition is one of the research hotspots. In order to facilitate...

  4. Tail-directed behaviour in pigs – relation to tail posture and tail lesion

    Contributor(s):: Wilder, Thore, Krieter, Joachim, Kemper, Nicole, Honeck, Anja, Büttner, Kathrin

    Tail-biting in pigs affects the health and welfare of the animals. Different indicators, such as the tail posture, can be used to detect tail-biting at an early stage. The aim of this study was to investigate the effect of tail-directed behaviour, differentiating between tail-biting and...

  5. Managing large litters: Selected measures of performance in 10 intermediate nurse sows and welfare of foster piglets

    Contributor(s):: Kobek-Kjeldager, Cecilie, Moustsen, Vivi A., Theil, Peter K., Pedersen, Lene J.

    Selection for increased litter size has led to the use of so-called nurse sows in several European countries. A nurse sow receives new piglets after having weaned her own. Nurse sows are often made in two-steps. In the two-step strategy, new-born piglets are given to a sow 4–7 days into...

  6. Early feeding experiences of piglets and their impact on novel environment behaviour and food neophobia

    Contributor(s):: Middelkoop, Anouschka, Kemp, Bas, Bolhuis, J. Elizabeth

    We studied whether feeding experiences of piglets during lactation influence novel environment behaviour pre-weaning and food acceptance pre- and post-weaning. In a 2 × 2 arrangement, litters (n = 10/treatment) received creep feed as monotonous diet (MO) or four feed items as diverse diet (DD)...

  7. 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,...

  8. Aromatic Profile, Physicochemical and Sensory Traits of Dry-Fermented Sausages Produced without Nitrites Using Pork from Krškopolje Pig Reared in Organic and Conventional Husbandry

    Full-text: Available

    | Contributor(s):: Martin Škrlep, Marjeta Cˇ andek-Potokar, Nina Batorek-Lukac, Urška Tomažin, Mónica Flores

    Dry-fermented sausages were produced in a traditional way, without addition of nitrites and starter cultures, from meat of an autochthonous breed (Krškopolje pig) raised either in a conventional indoor or organic husbandry system. Physicochemical and sensory analyses were performed at...

  9. Factors Influencing Farmer Willingness to Reduce Aggression between Pigs

    Full-text: Available

    | Contributor(s):: Rachel S. E. Peden, Faical Akaichi, Irene Camerlink, Laura A. Boyle, Simon P. Turner

    Aggression between pigs remains an important animal welfare issue despite several solutions existing. Uptake of livestock welfare research relies on various stakeholders being willing to recommend or adopt changes to farm structure or management (e.g., veterinarians, researchers, farmers). This...

  10. Farmer Perceptions of Pig Aggression Compared to Animal-Based Measures of Fight Outcome

    Full-text: Available

    | Contributor(s):: Rachel S.E. Peden, Irene Camerlink, Laura A. Boyle, Faical Akaichi, Simon P. Turner

    Several animal welfare issues persist in practice despite extensive research which has been linked to the unwillingness of stakeholders to make changes. For example, most farmers do not perceive pig aggression to be a problem that requires action despite the fact that stress and injuries are...

  11. Which types of rooting material give weaner pigs most pleasure?

    | Contributor(s):: Ocepek, Marko, Newberry, Ruth C., Andersen, Inger Lise

    Provision of rooting material as enrichment for pigs has been primarily oriented towards reducing negative affect (suffering). Information is also needed on the impact of different types of rooting materials in promoting positive affect (pleasure). We hypothesised that repeated addition of fresh...

  12. Dyadic affiliative preferences in a stable group of domestic pigs

    | Contributor(s):: Goumon, Sébastien, Illmann, Gudrun, Leszkowová, Iva, Dostalová, Anne, Cantor, Mauricio

    Social preferences in pigs have received little attention despite the welfare implication of providing an adequate social environment for farm animals. We investigated the extent to which domestic pigs show affiliative preferences in three behavioural contexts—rest, exploration, social nosing—and...

  13. The opening of a hinged farrowing crate improves lactating sows’ welfare

    | Contributor(s):: Ceballos, Maria Camila, Góis, Karen Camille R., Parsons, Thomas D.

    Concerns about the welfare of lactating sows housed in farrowing crates have emerged because crates physically restrict the sows and possibly compromise their behavior and comfort. The aim of this study was to identify how the opening of a hinged farrowing crate on different days (4 or 7)...

  14. Tail postures and tail motion in pigs: A review

    | Contributor(s):: Camerlink, Irene, Ursinus, Winanda W.

    Animals’ tail posture and motion play an important role in communication, amongst others. In domestic pigs, the debate around tail docking and tail biting has made the tail an important research topic, and tail-related behaviour is increasingly proposed as a welfare indicator. While the focus is...

  15. Who turns to the human? Companion pigs' and dogs' behaviour in the unsolvable task paradigm

    | Contributor(s):: Perez Fraga, P., Gerencser, L., Lovas, M., Ujvary, D., Andics, A.

  16. Efforts to Ban the Routine Tail Docking of Pigs and to Give Pigs Enrichment Materials via EU Law: Where Do We Stand a Quarter of a Century on?

    Full-text: Available

    | Contributor(s):: Elena Nalon, Nancy De Briyne

    In its role as guardian of the Treaties, the European Commission must ensure that Member States enforce EU law within their territories. If adequate enforcement is found to be wanting, the Commission also has the power to take infringement procedures as a corrective measure. The case of...

  17. Reliability of Fear Assessment in Growing Pigs Exposed to a Novel Object Test in Commercial Conditions

    | Contributor(s):: Dalmau, Antoni, Mainau, Eva, Velarde, Antonio

    The objective of this study was to assess the reliability and feasibility of a novel object test assessing fear in pigs in commercial conditions. A total of 18 commercial farms were visited, and 321 pens housing 4,220 growing pigs were assessed. Three balloons were used as a novel stimulus....

  18. Does the location of enrichment material affect behavior and dirtiness in growing female pigs?

    | Contributor(s):: Dalmau, Antoni, Areal, Bruno, Machado, Silvana, Pallisera, Joaquim, Velarde, Antonio

    The objective of this study was to investigate if female growing pigs spend similar amounts of time exploring a wooden stick as they do exploring enrichment material regardless of its proximity to the feeder. Forty-eight pigs aged 18 to 26 weeks allocated to 16 pens with three pigs per pen were...

  19. Behavioral indicators of slow growth in nursery pigs

    | Contributor(s):: He, Yijie, Deen, John, Shurson, Gerald C., Li, Yuzhi Z.

    The objective of this study was to determine how feeder-space allowance affects behaviors of slow- and fast-growing pigs during the nursery period. Nursery pigs (n = 192; initial weight = 7.4 ± 1.6 kg) were housed in 24 pens of 8 pigs, with 12 pens provided with either a two-space feeder or a...

  20. Tail biting behaviour and tail damage in pigs and the relationship with general behaviour: Predicting the inevitable?

    | Contributor(s):: Ursinus, Winanda W., Van Reenen, Cornelis G., Kemp, Bas, Bolhuis, J. Elizabeth

    Tail biting behaviour in pigs is a common problem in conventional housing systems. Our study examined the consistency over time in tail biting and tail damage and it explored the predictive value of general behaviours observed in individual pigs and in pens as a whole. Pigs (n=480), reared in...
