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....
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...
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...
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...
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...
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...
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...
Effects of previous housing system on agonistic behaviors of growing pigs at mixing
Contributor(s):: Li, Yuzhi, Wang, Lihua
Previous studies indicated that rearing environment in early life affects behavioral development, which consequently modifies behavioral response of pigs to stressful environments in later stages of the production. A study was conducted to investigate effects of group-farrowing system on behavior...
Effect of short and long periods of separation on agonistic behaviour, injuries and stress in Hérens cows kept in loose housing
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...
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...
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...
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...
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...
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...
