  1. Effects of feeding management and group composition on agonistic behaviour of group-housed horses

    Contributor(s):: Burla, J. B., Ostertag, A., Patt, A., Bachmann, I., Hillmann, E.

    Under natural conditions, horses spend 12-18 h of a day with synchronous grazing, but for stabled horses, the amount of forage and thus duration of feed intake usually are restricted. In group-housed horses, therefore, feeding times are often situations with increased levels of agonistic...

  2. Long-term effects of straw blocks in pens with finishing pigs and the interaction with boar type

    Contributor(s):: Bulens, A., Beirendonck, S. van, Thielen, J. van, Buys, N., Driessen, B.

    This study verified the effect of straw blocks on the behavior and growth of finishing pigs and possible interactions with the genetic background (boar type). A total of 359 finishing pigs, which were offspring from different boar types, were housed in gender-mixed pens with slatted floors. Half...

  3. Degree of synchrony based on individual observations underlines the importance of concurrent access to enrichment materials in finishing pigs

    Contributor(s):: Zwicker, B., Weber, R., Wechsler, B., Gygax, L.

    Pigs are sociable animals with a strong motivation to explore and forage, and it has been stated that they have a strong motivation to do so synchronously. We examined the synchrony of exploration in groups of finishing pigs when enrichment materials were offered. We used a novel measure of...

  4. Effect of increasing amounts of straw on pigs' explorative behaviour

    Contributor(s):: Jensen, M. B., Herskin, M. S., Forkman, B., Pedersen, L. J.

    According to European legislation, pigs must have permanent access to sufficient quantity of material to enable manipulation activities. However, few studies have quantified how much straw is needed to fulfil the requirements of growing pigs. We investigated the effect of increasing amount of...

  5. Hunger in pregnant sows: effects of a fibrous diet and free access to straw

    Contributor(s):: Jensen, M. B., Pedersen, L. J., Theil, P. K., Knudsen, K. E. B.

    Fibrous diets and the provision of straw have been suggested to reduce feeding motivation in pregnant sows. The present experiment investigated the separate and interactive effects of a fibrous diet and ad libitum access to straw on feeding motivation, oral behaviour and plasma levels of...

  6. Straw applications in growing pigs: effects on behavior, straw use and growth

    Contributor(s):: Bulens, A., Beirendonck, S. van, Thielen, J. van, Buys, N., Driessen, B.

    The short-term effects of four straw applications on pigs housed on slatted floors were investigated to determine differences in behavior, straw use and growth. Both the type of straw used and the design of the application might influence the attractiveness and effectiveness of the applications....

  7. 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...

  8. Fresh wood reduces tail and ear biting and increases exploratory behaviour in finishing pigs

    Contributor(s):: Telkanranta, H., Bracke, M. B. M., Valros, A.

    Chewing and rooting are high behavioural priorities in pigs. Lack of suitable materials can lead to abnormal behaviours such as tail and ear biting. In commercial farming, slatted floors limit the use of straw, and various point-source objects have therefore been developed. The crucial challenge...

  9. What do calves choose to eat and how do preferences affect behaviour?

    Contributor(s):: Webb, L. E., Engel, B., Berends, H., Reenen, C. G. van, Gerrits, W. J. J., Boer, I. J. M. de, Bokkers, E. A. M.

    Calves raised for milk or meat are fed diets that differ from feral-herd calf diets and are based on the nutritional requirements of the 'average calf'. These diets may not meet the dietary preferences of each individual calf. This study explored diet preferences in calves with free dietary...

  10. How much is enough? The amount of straw necessary to satisfy pigs' need to perform exploratory behaviour

    Contributor(s):: Pedersen, L. J., Herskin, M. S., Forkman, B., Halekoh, U., Kristensen, K. M., Jensen, M. B.

    Since 10 years, EU-legislation states that 'pigs must have permanent access to sufficient quantity of material to enable proper investigation and manipulation activities'. While much research has focused on which materials 'enable proper investigation and manipulation activities', little has been...

  11. Effect of hiding places, straw and territory on aggression in group-housed rabbit does

    Contributor(s):: Rommers, J. M., Reuvekamp, B. J. F., Gunnink, H., Jong, I. C. de

    Group-housing of rabbit does may be preferred from welfare point of view. However, group-housing causes agonistic behaviour which may cause severe injuries. Severe injuries may be prevented by offering hiding places for attacked does. Providing enrichment (straw) may reduce agonistic behaviour by...

  12. Nest building and posture changes and activity budget of gilts housed in pens and crates

    Contributor(s):: Andersen, I. L., Vasdal, G., Pedersen, L. J.

    The aim of the present work was to study nest building, posture changes and the overall activity budget of gilts in pens vs. crates. Twenty-three HB gilts (high piglet survival day 5) and 21 LB gilts (low piglet survival day 5) were video recorded from day 110 in pregnancy to four days after...

  13. An exploratory study on the effects of a straw dispenser in farrowing crates

    Contributor(s):: Bulens, A., Renders, L., Beirendonck, S. van, Thielen, J. van, Driessen, B.

    The effect of a straw dispenser in farrowing crates was investigated to determine the extent to which the provision of small quantities of straw has an influence on both sows and piglets. Sows and suckling piglets are often housed in barren environments with limited opportunities to show behavior...

  14. Effects of neonatal castration on social behaviour, human-animal relationship and feeding activity in finishing pigs reared in a conventional or an enriched housing

    Contributor(s):: Tallet, C., Brillouet, A., Meunier-Salaun, M. C., Paulmier, V., Guerin, C., Prunier, A.

  15. Short- and long-term effects of eight enrichment materials on the behaviour of finishing pigs fed ad libitum or restrictively

    Contributor(s):: Zwicker, B., Gygax, L., Wechsler, B., Weber, R.

  16. The pig's nose and its role in dominance relationships and harmful behaviour

    Contributor(s):: Camerlink, I., Turner, S. P.

  17. Alternative housing systems for fattening bulls under Austrian conditions with special respect to rubberised slatted floors

    Contributor(s):: Rouha-Muelleder, C., Absmanner, E., Kahrer, E., Zeiner, H., Scharl, T., Leisch, F., Stanek, C., Troxler, J.

  18. Behaviour and welfare of veal calves fed different amounts of solid feed supplemented to a milk replacer ration adjusted for similar growth

    Contributor(s):: Webb, L. E., Bokkers, E. A. M., Engel, B., Gerrits, W. J. J., Berends, H., Reenen, C. G. van

  19. Differing results for motivation tests and measures of resource use: the value of environmental enrichment to gestating sows housed in stalls
