  1. Mate choice, maternal investment and implications for ostrich welfare in a farming environment

    Contributor(s):: Bonato, M., Cherry, M. I., Cloete, S. W. P.

    At present, the ostrich industry is inefficient, on account of being characterised by inadequate egg production, high embryo mortality, poor chick survival and suboptimal growth rates. However, as ostrich farming commenced only in the mid 19th century in South Africa, farmed ostriches have had a...

  2. 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...

  3. 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...

  4. 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...

  5. 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...

  6. 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...

  7. 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...

  8. A model to predict the likelihood of cliff swallow nesting on highway structures in northern California

    Contributor(s):: Coates, R. W., Delwiche, M. J., Gorenzel, W. P., Salmon, T. P.

  9. 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,...

  10. Determinants of reproductive success in force-re-paired cockatiels ( Nymphicus hollandicus )

    Contributor(s):: Stone, E. G., Millam, J. R., El-Halawani, M. E., Phillips, R. E., Redig, P. T.

    58 previously paired cockatiels were re-paired with mates with which they had never been previously paired. Males (M) and females (F) were assigned a breeding history that was 'experienced' (E) or 'inexperienced' (I), depending on whether they were part of a pair that had hatched at least one egg...

  11. Development with age of nest box use and gregarious nesting in laying hens

    Contributor(s):: Riber, A. B.

    Use of nest boxes is an important part of the behavioural repertoire of laying hens kept under commercial conditions. A special form of nest box use is gregarious nesting, which occurs when a hen given the choice between an occupied and an unoccupied nest site chooses the occupied nest site....

  12. 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...

  13. 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...

  14. 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...

  15. The impact of social factors on nesting in laying hens ( Gallus gallus domesticus )

    Contributor(s):: Lundberg, A., Keeling, L. J.

    The effects of competition and disturbances on nest-site selection were studied in commercial laying hens. Hens were housed in 16-litter floor pens (15, 30, 60 and 120 hens per group x 4 replicates) and the levels of aggression and disturbances were compared between nest boxes and pen corners....

  16. Thwarting of behaviour in different contexts and the gakel-call in the laying hen

    Contributor(s):: Zimmerman, P. H., Koene, P., Hooff, J. A. R. A. M. van

    Earlier studies have shown that thwarting of feeding behaviour in the laying hen is expressed through a specific vocalization, the gakel-call. The first aim of this study was to investigate whether the effect of deprivation per se on the occurrence of gakel-calls can be distinguished from the...

  17. 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....

  18. 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...

  19. Life in a variable world: behaviour, welfare and environmental design

    Contributor(s):: Appleby, M. C.

  20. 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...
