  1. Partial tooth-clipping of suckling pigs: effects on neonatal competition and facial injuries

    Contributor(s):: Weary, D. M., Fraser, D.

    Two experiments investigated the effects on facial injury and piglet performance of partial clipping of needle teeth, whereby only the distal third of the tooth is removed. In experiment 1, teeth were partially clipped, fully clipped to the gum line, or left intact. All piglets of a litter...

  2. Personalities in female domesticated pigs: behavioural and physiological indications

    Contributor(s):: Ruis, M. A. W., Brake, J. H. A. te, Burgwal, J. A. van de, Jong, I. C. de, Blokhuis, H. J., Koolhaas, J. M.

    A total of 128 gilts from 31 sows were systematically studied from birth to slaughter in two identical trials. Intra-test consistency in individual behavioural and/or physiological reactions was studied in three different tests. There were no consistencies in reactions of gilts over time to a...

  3. Reduction in cross-sucking in calves by the use of a modified automatic teat feeder. (Special issue: Suckling)

    Contributor(s):: Weber, R., Wechsler, B.

    Cross-sucking may be a problem in group-housed calves fed by automatic teat feeders. In the present study, the behaviour of calves fed by a conventional feeder with an open feeding stall (n=15 calves) was compared with the behaviour of calves fed by a modified feeder, which closes in the rear...

  4. Some aspects of milk that elicit non-nutritive sucking in the calf

    Contributor(s):: Passille, A. M. de, Rushen, J., Janzen, M.

    Male Holstein dairy calves were allowed to suck a non-nutritive teat after meals of either cow milk or milk replacer, and the amount of non-nutritive sucking that occurred during the 10 min following the meal was observed. There were no differences between milk and commercial milk replacer in the...

  5. Sow behaviour involved in the crushing of piglets in outdoor farrowing huts - a brief report

    Contributor(s):: Vieuille, C., Berger, F., Pape, G. le, Bellanger, D.

    This study focuses on maternal activities involved in the trapping of piglets by the sow's body in outdoor farrowing systems and examine the mother-piglet context leading either to the death of piglets or to their survival. The behaviour of six Large-White x Landrace sows and their litters was...

  6. Sucking motivation and related problems in calves. (Special issue: Suckling)

    Contributor(s):: Passille, A. M. de

    Because the survival of young mammals depends on sucking success, it is assumed that sucking motivation must be strong and that sucking deprivation would result in frustration, which could have a negative impact on the animals' welfare. This concern, as well as that regarding cross-sucking...

  7. The development of intersucking in dairy calves around weaning

    Contributor(s):: Keil, N. M., Langhans, W.

    Intersucking, i.e. sub-adult or adult cattle sucking at the udder of herd-members, is a problem often reported in dairy herds that leads to udder health problems. The causes of intersucking are virtually unknown, and until now all available countermeasures treat only the symptoms of this...

  8. The effect of a gradual separation from the mother on later behavioral, immune and endocrine alterations in artificially reared lambs

    Contributor(s):: Sevi, A., Caroprese, M., Annicchiarico, G., Albenzio, M., Taibi, L., Muscio, A.

    The aim of the experiment was to compare the welfare and weight gains of artificially reared lambs when gradually separated from their mothers or separated from them early and immediately or gradually moved from maternal to reconstituted milk. Forty Comisana lambs were assigned to a control...

  9. The effects of conditioning to suckling, milking and of calf presence on the release of oxytocin in dairy cows. (Special issue: Suckling)

    Contributor(s):: Tancin, V., Kraetzl, W. D., Schams, D., Bruckmaier, R. M.

    The aim of this study was to record oxytocin (OT) release during milking (M) in the presence or absence of a calf, suckling (S) and calf removal just before the next milking in cows during postpartum or early lactation periods. Furthermore, the release of OT was examined during S and M in unknown...

  10. Behaviour of dairy calves suckling the dam in a barn with automatic milking or being fed milk substitute from an automatic feeder in a group pen

    Contributor(s):: Froberg, S., Lidfors, L.

    The aim of this study was to investigate the suckling behaviour of dairy calves allowed to suckle freely in a barn with an automatic milking (AM) system and how their behaviour differed from the behaviour of calves given milk substitute from an automatic feeder. For the first 8 weeks of life,...

  11. Behaviour of Zebu and crossbred cows in restricted suckling groups. (Special issue: Suckling)

    Contributor(s):: Das, S. M., Redbo, I., Wiktorsson, H.

    The aim of this study was to investigate whether Zebu (Bos indicus) and crossbred (Bos indicus x Bos taurus) cows differ in maternal related behaviour during restricted group suckling. The behaviours of 20 Zebu and 16 crossbred cows were recorded during two 30-min sessions each day after milking...

  12. Consequences of different suckling systems for reproductive activity and productivity of cattle in tropical conditions. (Special issue: Suckling)

    Contributor(s):: Galina, C. S., Rubio, I., Basurto, H., Orihuela, A.

    The late onset of ovarian activity in mature cattle raised under tropical conditions is the major setback impeding sound reproductive performance needed to meet the increasing demand for livestock products in the area. The effect of suckling has been cited as one of the most important factors...

  13. Effect of age of calf on suckling behaviour and other behavioural activities of zebu and crossbred calves during restricted suckling periods

    Contributor(s):: Das, S. M., Redbo, I., Wiktorsson, H.

    The behaviours of (i) 20 zebu and (ii) 16 crossbred calves were recorded during two 30-min sessions each day after milking when the calves and their dams were brought together in a group for suckling. This was carried out for 2 weeks/month for 6 months postpartum. The total suckling duration was...

  14. Individual differences in aggression and physiology in peri-pubertal breeding gilts

    Contributor(s):: Geverink, N. A., Schouten, W. G. P., Gort, G., Wiegant, V. M.

    Several recent studies on pigs have demonstrated a relationship between the degree of resistance displayed in a so-called "backtest" and a variety of behavioural and physiological responses in piglets and young fattening pigs. However, the discussion about the predictive power of the backtest is...

  15. Maternal behaviour of domestic sows and crosses between domestic sows and wild boar

    Contributor(s):: Gustafsson, M., Jensen, P., Jonge, F. H. de, Illmann, G., Spinka, M.

    Maternal behaviour was compared in 7 (Yorkshire x Dutch Landrace) x Yorkshire sows (domestic) and 7 (Yorkshire x Dutch Landrace) x wild boar sows (wild-type) before and up to 3 weeks after farrowing. All sows were primiparous and were maintained in an outdoor system with farrowing huts containing...
