  1. Strategic use of straw increases nest building in loose housed farrowing sows

    Contributor(s):: Westin, R., Hultgren, J., Algers, B.

    In spite of domestication, sows are still genetically programmed to perform nesting behaviour close to farrowing. In order to facilitate nest building, a method for a strategic use of large quantities of straw has been developed by Swedish piglet producing farmers. The objectives of the present...

  2. Effect of pre- and post-partum sow activity on maternal behaviour and piglet weight gain 24 h after birth

    Contributor(s):: Illmann, G., Chaloupkova, H., Neuhauserova, K.

    Within the 24 h prior to parturition sows are active and motivated to perform nest-building behaviour. The aim of this study was to investigate: (i) whether pre-partum activity (e.g. nesting and postural changes) could predict maternal behaviour 24 h post-partum (pp) and weight gain 24 h pp, and...

  3. Effects of prepartum housing environment on abnormal behaviour, the farrowing process, and interactions with circulating oxytocin in sows

    Contributor(s):: Yun, JinHyeon, Swan, K. M., Oliviero, C., Peltoniemi, O., Valros, A.

    We evaluated the effects on sows of prepartum housing environment on bar-biting (BB) behaviour prior to parturition, farrowing duration from first to tenth piglets, litter size, and circulating oxytocin (OT) concentrations during birth of the first five piglets. A total of 35 sows, approximately...

  4. Housing condition and nesting experience do not affect the Time to Integrate to Nest Test (TINT)

    Contributor(s):: Rock, M. L., Karas, A. Z., Gallo, M. S., Pritchett-Corning, K., Gaskill, B. N.

    Managing and assessing well-being in laboratory mice ( Mus musculus) is both challenging and necessary. Assessments intended to detect negative welfare states in mice are usually performed via observation of animals in the home cage, but a substantial amount of time and skill may be required to...

  5. The physiological and behavioural impact of sensory contact among unfamiliar adult mice in the laboratory

    Contributor(s):: Rettich, A., Kasermann, H. P., Pelczar, P., Burki, K., Arras, M.

    Housing mice in the laboratory in groups enables social interaction and is the way a laboratory should house mice. However, adult males show reciprocal aggression and are therefore frequently housed individually. Alternatively, a grid divider, which allows sensory contact by sight and smell but...

  6. Human-dog interactions and behavioural responses of village dogs in coastal villages in Michoacan, Mexico

    Contributor(s):: Ruiz-Izaguirre, E., Eilers, K. H. A. M., Bokkers, E. A. M., Ortolani, A., Ortega-Pacheco, A., Boer, I. J. M. de

    In Mexican villages, most households keep dogs that roam freely. Therefore, socialisation of village dogs occurs in a different context than that of companion dogs in developed countries. The objectives of this study were: (1) to assess village dogs' behavioural responses towards familiar and...

  7. Characteristics of wild pig farrowing nests and beds in the upper Coastal Plain of South Carolina

    Contributor(s):: Mayer, J. J., Martin, F. D., Brisbin, I. L., Jr.

    Thirteen farrowing nests and 9 resting/loafing beds built by wild pigs (Sus scrofa) from an introduced population in South Carolina, USA, were studied with respect to physical description, size parameters, the animals involved, and adjacent surroundings. The nests, built by pre-parturition sows,...

  8. Influence of environmental stimuli on nest building and farrowing behaviour in domestic sows

    Contributor(s):: Thodberg, K., Jensen, K. H., Herskin, M. S., Jorgensen, E.

    The effects of floor type (sand vs. concrete) and substrate type (straw feeder vs. no straw feeder) were examined using a 2 x 2 factorial design with 9 replicates of 4 multiparous sows. From 1 week prepartum until 2 weeks after farrowing, sows were penned individually in roofed 7.6 msuperscript 2...

  9. Nest building and farrowing in sows: relation to the reaction pattern during stress, farrowing environment and experience

    Contributor(s):: Thodberg, K., Jensen, K. H., Herskin, M. S.

    Nest building and farrowing behaviour of 40 Landrace/Yorkshire (L/Y) sows was studied in their first and second parity. In the first parity, the gilts were either housed in a crate or a "get-away-pen" (GAP) and in the second parity, either the same farrowing environment was used again or the sow...

  10. Nursing behaviour, postpartum activity and reactivity in sows: effects of farrowing environment, previous experience and temperament

    Contributor(s):: Thodberg, K., Jensen, K. H., Herskin, M. S.

    Postpartum behaviour during the first 24 h after farrowing (day 0 pp) and on day 10 pp of 40 Landrace/Yorkshire sows was studied in their first and second parity in a crossover experiment regarding farrowing environment (crate vs. get-away-pen (GAP)). The behaviour was compared with the...

  11. Periparturient nest building: implications for parturition, kit survival, maternal stress and behaviour in farmed mink ( Mustela vison )

    Contributor(s):: Malmkvist, J., Palme, R.

    Several types of nesting materials with different capacity as substrate for nest building are currently supplied to farmed mink. We investigated whether different nesting resources and possibility of performing periparturient nest-building influenced (a) the parturition, (b) the vitality and...

  12. Deprivation of straw bedding alters PGF<sub>2 alpha </sub>-induced nesting behaviour in female pigs

    Contributor(s):: Burne, T. H. J., Murfitt, P. J. E., Gilbert, C. L.

    Sows are highly motivated to build a maternal nest on the day preceding parturition. A model for nest building has been established in pigs, in which exogenously administered prostaglandin F2 alpha (PGF2 alpha ) may be used to elicit nesting behaviour in cyclic, pseudopregnant and pregnant pigs....

  13. Does feed-back from a nest affect periparturient behaviour, heart rate and circulatory cortisol and oxytocin in gilts?

    Contributor(s):: Damm, B. I., Pedersen, L. J., Marchant-Forde, J. N., Gilbert, C. L.

    To determine the effects of feed-back from a farrowing nest on periparturient behaviour, heart rate and hormones, 20 gilts housed in Schmid pens were permitted to build a nest of peat, straw and branches. Ten gilts then had their nest removed (NR) 10 h after the onset of nest-building and again...

  14. PGF<sub>2 alpha </sub>-induced nest building and choice behaviour in female domestic pigs

    Contributor(s):: Burne, T. H. J., Murfitt, P. J. E., Johnston, A. N. B.

    The domestic pig, Sus scrofa, builds a maternal nest in the day before parturition. A model for porcine nest building has been established, in which exogenously administered prostaglandin (PG)F2 alpha is used to induce nesting behaviour in cyclic, pseudopregnant and pregnant pigs. This...

  15. 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...

  16. The effects of branches on prepartum nest building in gilts with access to straw

    Contributor(s):: Damm, B. I., Vestergaard, K. S., Schroder-Petersen, D. L., Ladewig, J.

    Sows farrowing in a semi-natural environment terminate nest building 1-7 h prior to parturition after having built a nest for which a variety of materials are used. No nest-building behaviour occurs during parturition and the sows remain lying in the nest throughout most of the farrowing. In...

  17. The effects of confinement on periparturient behaviour and circulating prolactin, prostaglandin F<sub>2 alpha </sub> and oxytocin in gilts with access to a variety of nest materials

    Contributor(s):: Damm, B. I., Bildsoe, M., Gilbert, C., Ladewig, J., Vestergaard, K. S.

    In a 2x2 factorial experiment, the effects of gestation and farrowing housing on: (1) periparturient behaviour and circulating prolactin, prostaglandin F2 alpha (PGF2 alpha ) and oxytocin in gilts with access to peat, straw and branches, and (2) correlational relationships between the...

  18. Shelter choice by Syrian hamsters ( Mesocricetus auratus ) in the laboratory

    Contributor(s):: Veillette, M., Reebs, S. G.

    The preference of Syrian hamsters (Mesocricetus auratus) for different in-cage shelters was tested. First, 15 males and 15 females were made to choose between a cage with a shelter and one without. Different shelters were tested consecutively: short (10-cm) or medium (15-cm) pipes made of black...

  19. Preference of Syrian hamsters to nest in old versus new bedding

    Contributor(s):: Veillette, M., Reebs, S. G.

    This study tested whether Syrian hamsters (Mesocricetus auratus) have an aversion to old bedding (up to 14 days) by offering them the option to nest in a new cage. A secondary goal was to assess the relative value of shelters by testing whether the tendency to nest in the new cage was reduced...

  20. Strength of preference for nesting material as environmental enrichment for laboratory mice

    Contributor(s):: Weerd, H. A. van de, Loo, P. L. P. van, Zutphen, L. F. M. van, Koolhaas, J. M., Baumans, V.

    The presence of nesting material (paper towel or tissue) and the presence of a nest box (perforated metal or clear perspex box) were evaluated in 47 mice. On average, all the mice spent significantly more time in the cage with the nesting material (more than 69% of their total time, less than 25%...
