    Contributor(s):: Bornett-Gauci, H. L. I., Martin, J. E., Arney, D. R.

  2. Characterisation of sows' postures and posture changes with regard to crushing piglets

    | Contributor(s):: Wischner, D., Kemper, N., Stamer, E., Hellbruegge, B., Presuhn, U., Krieter, J.

    The aim of this study was to analyse different behavioural traits of sows to describe posture changes and to determine the influences of these traits on piglet losses. The behaviour of 386 German Landrace sows (with 438 pure-bred litters) was videotaped continuously starting 12 h prepartum until...

  3. Effects of feed-back from the nest on maternal responsiveness and postural changes in primiparous sows during the first 24 h after farrowing onset

    | Contributor(s):: Pedersen, L. J., Damm, B. I., Marchant-Forde, J. N., Jensen, K. H.

    In order to elucidate whether feed-back from a farrowing nest affects the sows' activity level and responsiveness to piglets during the first 24 h after the onset of parturition, 18 primiparous Landrace x Yorkshire sows were given the opportunity to build a farrowing nest of peat, straw and...

  4. Evidence of a limited role for prolactin in the preparturient activity of confined gilts

    | Contributor(s):: Rushen, J., Robert, S., Farmer, C.

    To investigate the role of peripheral prolactin in stimulating the preparturient activity of pigs, 12 cross-bred gilts housed in standard farrowing crates either received orally 10 mg of bromocriptine three times per day from day 110 of gestation or served as controls. Jugular blood samples were...

  5. Sow behaviour towards humans during standard management procedures and their relationship to piglet survival

    | Contributor(s):: Lensink, B. J., Leruste, H., Bretagne, T. de, Bizeray-Filoche, D.

    Piglet crushing remains a major problem in pig production and is partly related to sow behavioural traits. The sows' responses to the presence of humans around farrowing could partly contribute to piglet crushing through increased reactivity and getting up and lying down behaviour. The aim of...

  6. Synthetic lying mats may improve lying comfort of gestating sows

    | Contributor(s):: Tuyttens, F. A. M., Wouters, F., Struelens, S., Sonck, B., Duchateau, L.

    A prototype lying mat as an alternative to straw bedding for improving sow lying comfort was evaluated using a dynamic group of 47 gestating sows housed in a pen with 5 communal lying areas. Mats were installed in 3 lying areas while the concrete floors of the remaining lying areas remained...

  7. Tail posture predicts tail damage among weaned piglets

    | Contributor(s):: Zonderland, J. J., Riel, J. W. van, Bracke, M. B. M., Kemp, B., Hartog, L. A. den, Spoolder, H. A. M.

    Tail biting in pigs is a widespread behavioural vice with significant animal welfare and economic consequences. All too often, tail biting is not diagnosed nor dealt with until tail damage is present. To effectively reduce the negative effects of tail biting, it must be diagnosed in an early...

  8. Lying characteristics as determinants for space requirements in pigs

    | Contributor(s):: Ekkel, E. D., Spoolder, H. A. M., Hulsegge, I., Hopster, H.

    An experiment was carried out to study the lying postures, space occupation and percentage of space-sharing (as a consequence of huddling behaviour) in pigs. Information about these lying characteristics is essential for the calculation of lying space requirements, e.g. for pen design legislative...

  9. Maternal feed intake, but not feed composition affects postural behaviour and nursing frequency of lactating primiparous sows

    | Contributor(s):: Brand, H. van den, Schouten, W. G. P., Kemp, B.

    Effects of feed intake (high: 44 or low: 33 MJ NE per day) and major dietary energy source (fat: 131 g/kg fat, 183 g/kg starch plus sugar; starch: 31 g/kg fat, 351 g/kg starch plus sugar) of lactating primiparous sows on postural behaviour (lying, sitting, standing) and nursing frequency were...

  10. Parturient behaviour and offspring-directed aggression in farmed wild boar of three genetic lines

    | Contributor(s):: Harris, M. J., Bergeron, R., Gonyou, H. W.

    Twenty-four primiparous farmed wild boar females of three genetic lines (SD, San Diego; PK, Peter Kalden; S, Scandinavian) were videotaped before and during parturition; production data were also recorded. Sows were housed in individual, well-strawed pens measuring 3.05 m x 1.52 m. The duration...

  11. Relationship between postural behaviour and gestation stall dimensions in relation to sow size

    | Contributor(s):: Anil, L., Anil, S. S., Deen, J.

    The extent to which the size of the gestation stall, relative to the size of the sow, affects the normal basic postural behavioural needs of sows like standing, sitting and lying was assessed using 25 sows randomly selected from four farms. The postural behaviour of the animals was recorded using...

  12. The effect of parity and environmental restriction on behavioural and physiological responses of pre-parturient pigs

    | Contributor(s):: Jarvis, S., Vegt, B. J. van der, Lawrence, A. B., McLean, K. A., Deans, L. A., Chirnside, J., Calvert, S. K.

    There is increasing evidence that restriction of pre-parturient behaviour in pigs is stress-inducing, characterised by an elevation in hypothalamic-pituitary-adrenal (HPA) activity in gilts. To determine whether pigs adapt to behavioural restriction, through modification of nest-building...

  13. The effect of increasing dietary fibre and the provision of straw racks on the welfare of sows housed in small static groups

    | Contributor(s):: Stewart, C. L., Boyle, L. A., O'Connell, N. E.

    This study assessed the effects of increasing dietary fibre levels in concentrate rations and providing access to straw in racks on the welfare of pregnant sows housed in small static groups. In a 2x2 factorial design experiment, 128 Large White x Landrace pregnant sows were offered one of two...

  14. Pre-lying behaviour patterns in confined sows and their effects on crushing of piglets

    | Contributor(s):: Wischner, D., Kemper, N., Stamer, E., Hellbrugge, B., Presuhn, U., Krieter, J.

    In order to determine the influences of different posture patterns of sows on piglet losses, the present study aimed at the analysis of different elements of pre-lying behaviour peri and post partum. Over the course of 1 year, the behaviour of 386 German Landrace sows (with 438 pure-bred...

  15. Validation of accelerometers to automatically record sow postures and stepping behaviour

    | Contributor(s):: Ringgenberg, N., Bergeron, R., Devillers, N.

    Two studies were performed to develop and validate an automated method of detecting postures and stepping behaviour in sows. In the first study, two accelerometers were simultaneously tested on 23 multiparous sows to detect the following postures: standing, sitting, lying ventrally and lying...

  16. Genetic variation of sitting frequency and duration in pigs

    | Contributor(s):: McGlone, J. J., Akins, C. K., Green, R. D.

    312 pigs from 62 litters were given food and water ad lib. The frequency and duration of sitting between 4 and 6 months of age were estimated from 24-h video recordings. Heritabilities were calculated using a full-sib analysis. The hsuperscript 2 for the duration of sitting was 0.41+or-0.14 and...

  17. Peripartum sows in three farrowing crates: posture patterns and behavioural activities

    | Contributor(s):: Lou, ZhengSheng, Hurnik, J. F.

    Groups of 32 sows in one of 3 types of farrowing crates, an ellipsoid crate developed in the study, a modified circular crate and a conventional rectangular crate were video-taped for observations of body postures and oral-nasal activities around parturition. These behaviours were compared among...

  18. The influence of human posture and movement on the approach and escape behaviour of weanling pigs

    | Contributor(s):: Miura, A., Tanida, H., Tanaka, T., Yoshimoto, T.

    This study examined the influence of human posture and movement on the behaviour of pigs. Thirty-six 3-week-old crossbred (DurocxLarge White) weanling pigs from 5 litters were used. In order to identify the main cues that pigs use when interacting with humans, several tests were conducted....

  19. Effects of weaning age on the behavioural and neuroendocrine development of piglets.

    | Contributor(s):: Jarvis, S., Moinard, C., Robson, S. K., Sumner, B. E. H., Douglas, A. J., Seckl, J. R., Russell, J. A., Lawrence, A. B.

    Adverse early life experiences can permanently "programme" increases in stress reactivity in adulthood. We investigated whether weaning, which involves maternal separation, at different ages, altered subsequent behaviour, physiology and neuroendocrine function in young pigs. The...

  20. Maternal responsiveness of sows towards piglet's screams during the first 24 h postpartum

    | Contributor(s):: Illmann, G., Neuhauserova, K., Pokorna, Z., Chaloupkova, H., Simeckova, M.

    In this study we focused on sow responsiveness towards piglet screams which are proposed to have an important link to posture changes and early piglet crushing. A sow's responsiveness to screams of her piglets was investigated along the first 24 h after birth, the period of highest mortality, in...
