  1. Early social experiences do not affect first lactation production traits, longevity or locomotion reaction to group change in female dairy cattle

    Contributor(s):: Valníčková, Barbora, Šárová, Radka, Špinka, Marek

    Under natural conditions cows and their calves live together. In dairy practice, calves are separated from their mothers within hours after birth and then housed individually. This study investigated the effects of the presence of the dam during the colostrum feeding period and subsequent group...

  2. Different regrouping schedules in semi group-housed rabbit does: Effects on agonistic behaviour, stress and lesions

    Contributor(s):: Braconnier, Michèle, Gómez, Yamenah, Gebhardt-Henrich, Sabine G.

    Although group housing of naturally social animals like rabbits (Oryctolagus cuniculus) is desirable for ethical reasons, social conflicts can significantly increase the risk for injuries as well as stress incidences and negatively affect their welfare. A common housing system in Switzerland is...

  3. Preliminary investigation of social interactions and feeding behavior in captive group-housed Tasmanian devils (Sarcophilus Harrisii)

    Contributor(s):: Skelton, Candice J. A., Stannard, Hayley J.

    As the number of Tasmanian devils (Sarcophilus harrisii) in captivity increases, an understanding of captive social dynamics and behavior is becoming increasingly important. In the wild, devils are solitary, although sometimes, they congregate to feed on a large carcass. However, it is common to...

  4. Parity Influences the Demeanor of Sows in Group Housing

    Contributor(s):: Clarke, Taya, Pluske, John R., Miller, David W., Collins, Teresa, Fleming, Patricia A.

    Across the globe, producers are moving from individual housing to group housing for sows during gestation. Producers typically group sows of a range of parities together, although the impacts are largely unknown. This study examined the behavioral expression at mixing for young, midparity, and...

  5. Hierarchy formation in newly mixed, group housed sows and management strategies aimed at reducing its impact

    Contributor(s):: Greenwood, Emma C., Plush, Kate J., van Wettere, William H. E. J., Hughes, Paul E.

    Aggression is at its highest when sows are first introduced to new animals and hierarchies are being established. Thus, methods to reduce aggression should focus on this period. The aggression that occurs during mixing results in physiological stress responses, which can have detrimental effects...

  6. The effect of pen design on free space utilization of sows group housed in gestation pens equipped with free access stalls

    Contributor(s):: Rioja-Lang, Fiona C., Hayne, Stephanie M., Gonyou, Harold W.

    This study investigated the implementation of walk-in/lock-in stalls (free access stalls) for group housed sows. The objectives were to compare two different pen configurations (‘I-pen’ vs. ‘T-pen’) by determining the proportion and type (size/parity) of sows that used the free space areas, and...

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

    Contributor(s):: Rommers, Jorine M., Reuvekamp, Berry J. F., Gunnink, Henk, de Jong, Ingrid C.

    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...

  8. Dairy calves’ adaptation to group housing with automated feeders

    Contributor(s):: Fujiwara, Mayumi, Rushen, Jeffrey, de Passillé, Anne Marie

    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...

  9. Bite marks in mink—Induced experimentally and as reflection of aggressive encounters between mink

    Contributor(s):: Hansen, Steffen W., Møller, Steen H., Damgaard, Birthe M.

    For many years, bite marks have been used as an indicator for aggression in mink production systems. However, the validity of bite marks as indicator of aggression has recently been questioned. We therefore tested the following hypotheses: (1) experimentally applied pressure to, or penetration...

  10. Regrouping rabbit does in a familiar or novel pen: Effects on agonistic behaviour, injuries and core body temperature

    Contributor(s):: Graf, Sylvia, Bigler, Lotti, Failing, Klaus, Würbel, Hanno, Buchwalder, Theres

    Regrouping female rabbits in group-housing systems is common management practice in rabbit breeding, which may, however, induce agonistic interactions resulting in social stress and severe injuries. Here we compared two methods of regrouping female rabbits with respect to their effects on...

  11. Getting around social status: Motivation and enrichment use of dominant and subordinate sows in a group setting

    Contributor(s):: Elmore, Monica Renee Pittman, Garner, Joseph Paul, Johnson, Anna Kerr, Kirkden, Richard D., Richert, Brian Thomas, Pajor, Edmond Anthony

    Gestating sow motivation for enriched environments is unknown, but is essential knowledge for developing housing that addresses animal welfare concerns. This study investigated whether the motivation of gestating sows for access to an enriched group pen (containing a rubber mat, straw, compost,...

  12. Effects of repeated regrouping on horse behaviour and injuries

    Contributor(s):: Christensen, Janne Winther, Søndergaard, Eva, Thodberg, Karen, Halekoh, Ulrich

    Domestic horses are faced with social challenges throughout their lives due to limitations in social contact, space restrictions and frequent changes in social companionship. This is in contrast to natural conditions where horses live in relatively stable harem bands. Currently, little is known...

  13. Effects of group stability on aggression, stress and injuries in breeding rabbits

    Contributor(s):: Andrist, Claude A., Bigler, Lotti M., Würbel, Hanno, Roth, Beatrice A.

    On Swiss rabbit breeding farms, group-housed does are usually kept singly for 12 days around parturition to avoid pseudogravidity, double litters and deleterious fighting for nests. After this isolation phase there is usually an integration of new group members. Here we studied whether keeping...

  14. The effect of group-housing with free-farrowing pens on reproductive traits and the behaviour of low-risk and high-risk crushing sows

    Contributor(s):: Grimberg-Henrici, C. G. E., Büttner, K., Lohmeier, R. Y., Burfeind, O., Krieter, J.

    Free-farrowing systems and group-housing systems for lactating sows are sensitive systems and require an optimal interaction of different environmental factors to be successful. The aim of the present study was to compare sows’ reproductive traits during lactation in two group-housing systems...

  15. Is tail biting in growing pigs reduced by a prolonged suckling period?

    Contributor(s):: Naya, Ashley, Traulsen, Imke, Gertz, Marvin, Hasler, Mario, Burfeind, Onno, große Beilage, Elisabeth, Krieter, Joachim

    It was the aim of the study to investigate the effect of a prolonged suckling period and group housing before weaning on tail biting in undocked nursery pigs. To do this, experiments with three treatment groups were investigated. In the first group, pigs were conventionally housed in pens with...

  16. Aggressiveness in group-housed rabbit does: Influence of group size and pen characteristics

    Contributor(s):: Zomeño, Cristina, Birolo, Marco, Zuffellato, Andrea, Xiccato, Gerolamo, Trocino, Angela

    The aim of this work was to study how the group size and the number of doorways in a pen may influence the aggressive interactions throughout the reproductive cycle among does kept in a part-time group housing system. Thirty-two crossbred multiparous pregnant rabbit does were housed in individual...

  17. Effects of group size on behaviour, growth and occurrence of bite marks in farmed mink

    Contributor(s):: Axelsson, Heléne M. K., Hansen, Steffen W., Loberg, Jenny, Lidfors, Lena

    The aims of this study were to investigate the occurrence of stereotypic behaviours and the activity level in farmed mink when group housed in climbing cages and if group housing increase aggression by assessing the prevalence of bite marks. This was studied in juvenile mink of the colour types...

  18. The effect of a compressed air stimulus on blocking times in a concentrate feeding station for horses in group housing

    Contributor(s):: Gülden, Aline, Büscher, Wolfgang

    Concentrate feeding stations are used to meet the different feeding requirements of group-housed horses. In practice, blocking times caused by horses remaining in the feeding station without concentrate allowance constrain the feeding process considerably. To date, the application of an electric...

  19. A novel method for the analysis of social structure allows in-depth analysis of sow rank in newly grouped sows

    Contributor(s):: Greenwood, E. C., Plush, K. J., van Wettere, W. H. E. J., Hughes, P. E.

    Chronic stress response in fearful animals can result in depression of growth and reproductive performance. It is therefore important to be aware of at risk animals in the herd. Thus far ‘hierarchy’ calculations have involved the use of fights won and lost on the day of mixing or successful...

  20. A synthetic olfactory agonist reduces aggression when sows are mixed into small groups

    Contributor(s):: Plush, Kate, Hughes, Paul, Herde, Paul, van Wettere, William

    Synthetic olfactory agonists mimic odours secreted by mammary glands in several mammal species and their application can reduce anxiety levels in both juvenile and adult animals. This investigation determined the effect of a commercially available synthetic olfactory agonist administration on...
