  1. Social interactions, cortisol and reproductive success of domestic goats (Capra hircus) subjected to different animal densities during pregnancy

    Contributor(s):: Vas, Judit, Chojnacki, Rachel, Kjøren, Marte Flor, Lyngwa, Charlotte, Andersen, Inger Lise

    Although goats in many countries are kept indoors in the winter season, during gestation and kidding, recommendations and regulations regarding available space per goat are highly variable. The effects of different housing conditions on the welfare and behaviour are understudied in this species....

  2. Out of sight or in too deep: Effect of visual barriers and water depth on agonistic behaviour and growth in hatchling saltwater crocodiles (Crocodylus porosus)

    Contributor(s):: Brien, Matthew L., Gienger, Christopher M., Webb, Grahame J., McGuinness, Keith, Christian, Keith A.

    This study tests the role of visual barriers and water depth on levels of agonistic behaviour and growth in hatchling Crocodylus porosus within the first 3 weeks of life. Ninety-six individuals from four separate clutches hatched over 2 days were divided across three treatments containing two...

  3. Effects of restraint with or without blinds at the feed barrier on feeding and agonistic behaviour in horned and hornless goats

    Contributor(s):: Hillmann, Edna, Hilfiker, Sandra, Keil, Nina Maria

    The strict dominance hierarchy in goats bears the risk of low-ranking goats not getting adequate access to feed, especially for goats in small groups. The aim of our study was to test the effect of restraint in headlocks with and without blinds at the feed barrier on feeding and agonistic...

  4. 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...

  5. Influence of origin litter on social rank, agonistic behaviour and growth performance of piglets after weaning

    Contributor(s):: Fels, Michaela, Hoy, Steffen, Hartung, Jörg

    In pig production, mixing of piglets after weaning is a common management practice often leading to severe fighting aimed at establishing a social hierarchy. The intention of our study was to investigate whether social rank of piglets obtained by fighting within 3 days after weaning and mixing...

  6. Influence of immunisation against GnRF on agonistic and mounting behaviour, serum testosterone concentration and body weight in male pigs compared with boars and barrows

    Contributor(s):: Albrecht, Anna-Katharina, grosse Beilage, Elisabeth, Kanitz, Ellen, Puppe, Birger, Traulsen, Imke, Krieter, Joachim

    The aim of the present study was to assess the effects of vaccination against boar taint on testosterone levels, body weight and behaviour in male fattening pigs when compared with boars and barrows. The study was carried out in two replicates over time. Pigs were allocated to fattening pens...

  7. Increasing the interval between winter outdoor exercise aggravates agonistic interactions in Hérens cows kept in tie-stalls

    Contributor(s):: Castro, Isabelle M. L., Gygax, Lorenz, Wechsler, Beat, Hauser, Rudolf

    Cows of the dual-purpose Hérens breed are highly motivated to engage in dominance interactions and thus famous for the cow fights traditionally organised by Swiss breeders. However, this characteristic may result in excessively aggressive behaviour when cows kept in tie-stalls meet during winter...

  8. Effect of short and long periods of separation on agonistic behaviour, injuries and stress in Hérens cows kept in loose housing

    Contributor(s):: Castro, Isabelle M. L., Gygax, Lorenz, Wechsler, Beat, Hauser, Rudolf

    Hérens cows are typically not dehorned and are therefore housed in tie-barns during winter. Recently, however, farmers have started to also use loose housing systems. They separate single cows from their herd for periods of a few days to ensure undisturbed calving and to avoid excessive activity...

  9. Effect of mares’ dominance rank on suckling behaviour in the loose housed domestic horses

    Contributor(s):: Komárková, Martina, Bartošová, Jitka, Dubcová, Jana

    Suckling is a main part of maternal investment in equids. The suckling period is crucial for adequate physical as well as psychical development of the foal. The rank of the mother and her aggressiveness could be factors responsible for later reproductive or social success of the foal. We...

  10. Dominance and growth of Diplodus sargus (Pisces: Sparidae) in small captive groups

    Contributor(s):: Gonçalves, Ana Ribeiro, de Sousa, Liliana Carvalho, Almada, Vitor Carvalho

    The dominance hierarchies and the growth rate of the commercially important fish Diplodus sargus were assessed in this study. Specifically, we tested the hypothesis that, if stable dominance orders were established, dominant fish would grow faster and show better condition factors than losers at...

  11. Agonistic behaviour after mixing in pigs under commercial farm conditions

    Contributor(s):: Stukenborg, Andreas, Traulsen, Imke, Puppe, Birger, Presuhn, Ulrich, Krieter, Joachim

    The aim of the study was to investigate agonistic behaviour of pigs after regrouping pigs under commercial sow farm conditions. The behavioural patterns were observed over a 48-h period, directly after weaning (PIG-28; n=647) and 40 days later (growing pigs, PIG-68; n=224). Agonistic interactions...

  12. Comprehensive analysis of affiliative and agonistic social networks in lactating dairy cattle groups

    Contributor(s):: Foris, Borbala, Zebunke, Manuela, Langbein, Jan, Melzer, Nina

    The social environment of dairy cattle is important for their welfare under modern housing and management conditions. Social tension can negatively affect individuals even in a well-designed and healthy environment whereas affiliative behaviour may improve their well-being. The complex social...

  13. Sham dustbathing in cages by subordinate hens is increased by a partition providing isolation

    Contributor(s):: Moroki, Yuko

    Subordinate hens express less sham dustbathing in cages than higher ranked hens, their bouts often being disturbed by a higher ranked hen. However, seeing conspecifics seems to encourage this behaviour by hens. So to avoid being disturbed, a partition between hens in a cage may facilitate sham...

  14. Effect of housing density on growth, agonistic behaviour, and activity in hatchling saltwater crocodiles (Crocodylus porosus)

    Contributor(s):: Brien, Matthew L., Webb, Grahame J., McGuinness, Keith A., Christian, Keith A.

    The purpose of this study was to examine the effect of density on growth rate, agonistic behaviour, activity and use of space by hatchling C. porosus in captivity. Hatchling C. porosus were raised in identical enclosures (1.5m2) at different densities (3.3, 6.7, 13.3 and 20.0hatchlings/m2; or...

  15. Effects of communal rearing and group size on breeding rabbits’ post-grouping behaviour and its relation to ano-genital distance

    Contributor(s):: Buijs, Stephanie, Vangeyte, Jürgen, Tuyttens, Frank A. M.

    Group housing is becoming the standard for many farm animal species, as it is seen as a more welfare friendly way of keeping gregarious animals. Aggression between female breeding rabbits currently obstructs the implementation of group housing for this species. Lack of social experience during...

  16. 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...

  17. Network characteristics and development of social structure of agonistic behaviour in pigs across three repeated rehousing and mixing events

    Contributor(s):: Buttner, K., Scheffler, K., Czycholl, I., Krieter, J.

    In commercial pig production, the mixing of unacquainted pigs is a standard procedure which leads to agonistic interactions with a wide range of individual pig behaviour. A reduction in these agonistic interactions positively affects animal health, welfare aspects and production parameters. With...

  18. 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...

  19. Head partitions at the feed barrier affect behaviour of goats

    Contributor(s):: Nordmann, E., Barth, K., Futschik, A., Palme, R., Waiblinger, S.

    Space allowance at the feeding places often forces goats to feed in close proximity, that is, less than their individual distances. In consequence, agonistic behaviour may increase as well as stress and injuries, while access to feed may decrease, especially in low-ranking goats. Partitions...

  20. Effects of growth-promoting technology on feedlot cattle behavior in the 21 days before slaughter

    Contributor(s):: Stackhouse-Lawson, K. R., Tucker, C. B., Calvo-Lorenzo, M. S., Mitloehner, F. M.

    There is growing interest in the animal welfare implications of growth-promoting technology used in feedlot cattle, namely hormonal implants, ionophores, antibiotics and β 2-adrenergic agonists. Previous studies have focused on the effects of implants on aggression, but little work has...
