  1. Interaction between sows’ aggressiveness post mixing and skin lesions recorded several weeks later

    | Contributor(s):: Tönepöhl, Björn, Appel, Anne K., Voß, Barbara, König von Borstel, Uta, Gauly, Matthias

    Group housing of pigs leads inevitably to more or less serious agonistic interactions during the establishment of the social rank order of the group. In order to reduce the number of severe agonistic interactions and thus the negative effects on well-being and performance, the use of genetic...

  2. 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...

  3. Agonistic behaviour, skin lesions and activity pattern of entire male, female and castrated male finishing pigs

    | Contributor(s):: Bunger, B., Schrader, L., Schrade, H., Zacharias, B.

    Fattening of intact boars is the least invasive alternative to the detrimental welfare effects of surgical castration of piglets. However, beside problems such as boar taint the divergent agonistic and sexual behaviour of boars may impair the pigs' welfare during fattening. To evaluate the effect...

  4. Dairy calves' preference for rearing substrate

    | Contributor(s):: Worth, G. M., Schutz, K. E., Stewart, M., Cave, V. M., Foster, M., Sutherland, M. A.

    Traditional substrate types for dairy calves, such as sawdust, are becoming difficult and/or expensive for farmers to obtain in New Zealand. Therefore, there is a need to evaluate alternative rearing substrates that provide an acceptable level of animal welfare. The preference of dairy calves for...

  5. Diurnal rhythms, locations and behavioural sequences associated with eliminative behaviours in fattening pigs

    | Contributor(s):: Guo, YuGuang, Lian, XinMing, Yan, PeiShi

    Understanding eliminative behaviours in pigs is very important to maintain individual and pen cleanliness. In this experiment, twenty fattening pigs were housed in four concrete floor pens with a floor space of 3.25 m 2 per pig and free accessibility of outdoor runs. We studied the diurnal...

  6. Group composition for fattening entire male pigs under enriched housing conditions - influences on behaviour, injuries and boar taint compounds

    | Contributor(s):: Holinger, M., Fruh, B., Hillmann, E.

    In organic farming, the production of pork from entire male pigs seems to be the most promising alternative to castration, as organic animal husbandry aims at high standards of animal welfare and elimination of mutilations. However, previous research on behaviour of entire male pigs was mostly...

  7. Modification of aviary design reduces incidence of falls, collisions and keel bone damage in laying hens

    | Contributor(s):: Stratmann, A., Frohlich, E. K. F., Gebhardt-Henrich, S. G., Harlander-Matauschek, A., Wurbel, H., Toscano, M. J.

    Non-cage housing systems for laying hens such as aviaries provide greater freedom to perform species-specific behavior and thus are thought to improve welfare of the birds; however, aviaries are associated with a high prevalence of keel bone damage (fractures and deviations), which is a major...

  8. The relevance of variations in group size and phenotypic appearance on the behaviour and movement patterns of young domestic fowl

    | Contributor(s):: Liste, G., Campderrich, I., Beltran Heredia, I. de, Estevez, I.

    Variations in the group size of laying hens might increase the risk of undesired behaviours with important consequences for the birds' health and welfare. However, larger groups housed at constant densities also translate into larger enclosures that may increase space efficiency, therefore...

  9. A comparison of tethering and pen confinement of dogs

    | Contributor(s):: Yeon, S. C., Golden, G., Sung, W., Erb, H. N., Reynolds, A. J., Houpt, K. A.

    This study compared the general activity and specific behaviours of 30 adult Alaskan sled dogs (19 males and 11 females) on 3.5-m tethers and in 5.9-m2 pens. The investigators used activity level and stereotypical behaviour as indicators of welfare. The dogs spent most of their time inactive,...

  10. Dairy calves' adaptation to group housing with automated feeders

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

    Group housing of dairy calves with automated milk feeders has likely welfare and labour saving advantages but delays in the calves adapting to the feeding system may reduce these advantages. We examined factors that influence calves' adaptation to the feeders. In Exp. 1, 77 Holstein calves were...

  11. Effect of gestation management system on gilt and piglet performance

    | Contributor(s):: Muns, R., Manzanilla, E. G., Manteca, X., Gasa, J.

    Individual gestation housing of pregnant sows in stalls from four weeks after mating is banned in the EU. Two experiments were conducted to study the effect of two gestation management and housing systems (STALL: gilts housed in stalls and PEN: gilts loose-housed in pens with increased feed...

  12. Influence of environmental conditions and facility on faecal glucocorticoid concentrations in captive pygmy rabbits ( Brachylagus idahoensis)

    | Contributor(s):: Scarlata, C. D., Elias, B. A., Godwin, J. R., Powell, R. A., Shepherdson, D., Shipley, L. A., Brown, J. L.

  13. 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.

  14. The effect of housing system on the behaviour and growth parameters of fattening rabbits

    | Contributor(s):: Postollec, G., Boilletot, E., Maurice, R., Michel, V.

  15. Alternative housing for sows and litters 1. Effects of sow-controlled housing on responses to weaning

    | Contributor(s):: Pajor, E. A., Weary, D. M., Fraser, D., Kramer, D. L.

    A sow-controlled housing system and its affects on production and welfare problems resulting from the abrupt separation of piglets from sows at weaning was investigated. 44 sows and litters were housed during lactation in either a 'confined' pen where the sow and litter were kept together, or a...

  16. Alternative housing for sows and litters: 2. Effects of a communal piglet area on pre- and post-weaning behaviour and performance

    | Contributor(s):: Weary, D. M., Pajor, E. A., Bonenfant, M., Ross, S. K., Fraser, D., Kramer, D. L.

    An experiment was conducted to determine how allowing piglets access to a communal area affects pre-weaning and post-weaning behaviour and performance. Litters were housed in pens with sows in crates until piglets reached 11 days of age. For 10 experimental cohorts, barriers between the pens of...

  17. Behaviour of growing lambs housed on straw or woodchip bedding materials and their preference for floor type

    | Contributor(s):: Wolf, B. T., Molloy, H. R. B., Trayte, M. J., Rose, M. T.

    Straw is widely used as a bedding material for housed sheep, but alternatives are needed in regions where straw is expensive or in short supply. The aim of this work was to compare time budgets, growth and food intake of growing, finishing lambs housed on either woodchip or straw bedding...

  18. Effect of a warm and flexible piglet nest heating system - the warm water bed - on piglet behaviour, live weight management and skin lesions

    | Contributor(s):: Ziron, M., Hoy, St

    The aim of this investigation was to develop and test a new heating system for young piglets. Video observations were recorded, once a week over a 24-h period, with the help of an infrared video technique. The recordings were analysed to determine how long the piglets would remain in the nest...

  19. Effects of early contact between non-littermate piglets and of the complexity of farrowing conditions on social behaviour and weight gain

    | Contributor(s):: Kutzer, T., Bunger, B., Kjaer, J. B., Schrader, L.

    In this study we tested if contact possibilities between non-littermate piglets and complexity of farrowing conditions affect the pre- and post-weaning behaviour, weight gain and skin lesions of piglets. Suckling sows were either kept in a group housing system (GH), in a single pen loose housing...

  20. Influence of different types of environmental enrichment on the behaviour of finishing pigs in two different housing systems: 3. Hanging toy versus rootable toy of the same material

    | Contributor(s):: Scott, K., Taylor, L., Gill, B. P., Edwards, S. A.

    This study aimed to assess the effects of (1) environmental enrichment with either straw bedding or a plastic toy and (2) the way in which the plastic toy was presented on the behaviour of finishing pigs in two different housing systems. One thousand and twenty four (Large White x Landrace) x...
