Test of temperament in mink is influenced by a shelf in the front of the cage and the stimulus size rather than by features of the test person
Contributor(s):: Henriksen, Britt I. F., Møller, Steen H., Malmkvist, Jens
The study evaluates the effect of different test conditions on the temperament of farm mink, using the stick test. We hypothesised that mink perceive some test conditions as more fear eliciting. Specifically, we hypothesised that (A) the dimension of the presented stimulus in the test, a wooden...
A consideration of the role of biology and test design as confounding factors in judgement bias tests
Contributor(s):: Whittaker, Alexandra L., Barker, Timothy H.
The assessment of positive emotional states in animals has been advanced considerably through the use of judgement bias testing. JBT methods have now been reported in a range of species. Generally, these tests show good validity as ascertained through use of corroborating methods of affective...
The effect of qualitative feed restriction in broiler breeder pullets on fear and motivation to explore
Contributor(s):: Tahamtani, Fernanda M., Riber, Anja B.
Restrictively fed broiler breeders are known to have increased motivation to explore and reduced fearfulness because hunger increases the motivation to search for and to acquire food, forcing the birds to face and engage with aversive stimuli that they would otherwise avoid. The aim of this study...
Reliability of Fear Assessment in Growing Pigs Exposed to a Novel Object Test in Commercial Conditions
Contributor(s):: Dalmau, Antoni, Mainau, Eva, Velarde, Antonio
The objective of this study was to assess the reliability and feasibility of a novel object test assessing fear in pigs in commercial conditions. A total of 18 commercial farms were visited, and 321 pens housing 4,220 growing pigs were assessed. Three balloons were used as a novel stimulus....
Temperamental turkeys: Reliability of behavioural responses to four tests of fear
Contributor(s):: Erasmus, Marisa, Swanson, Janice
Open field (OF), tonic immobility (TI), voluntary approach (VA) and novel object (NO) tests are used to assess fear responses, activity levels and coping styles of poultry. Fear tests are also used as part of welfare assessment programmes. Little is known about fear responses of turkeys....
Responses to novel situations of female and castrated male pigs with divergent social breeding values and different backtest classifications in barren and straw-enriched housing
Contributor(s):: Reimert, Inonge, Rodenburg, T. Bas, Ursinus, Winanda W., Kemp, Bas, Bolhuis, J. Elizabeth
The growth of a pig is not only affected by its own genes, but also by the genes of its pen mates. This indirect effect on a pig's growth is represented as social breeding value (SBV) in a newly developed breeding model. It has been hypothesized that pigs could affect their pen mates’ growth...
Linking cortisol responsiveness and aggressive behaviour in gilthead seabream Sparus aurata: Indication of divergent coping styles
Contributor(s):: Castanheira, Maria Filipa, Herrera, Marcelino, Costas, Benjamín, Conceição, Luís E. C., Martins, Catarina I. M.
Farmed animals, including fish, often exhibit a pronounced individual variation in stress coping styles with proactive and reactive individuals differing in a variety of neuroendocrine and behavioural responses. In this study we disclosed that individual differences in cortisol responsiveness...
Intraspecific attachment in adult domestic dogs (Canis familiaris): Preliminary results
Contributor(s):: Mariti, Chiara, Carlone, Beatrice, Ricci, Eva, Sighieri, Claudio, Gazzano, Angelo
Canis familiaris is a highly social species. Among the social relationships between two individuals, a particular case is represented by attachment bonds. The aim of the current study was to assess whether the bond between adult cohabitant dogs may be regarded as attachment. Twenty-two couples of...
Genetic analysis of the individual pig behaviour in backtests and human approach tests
Contributor(s):: Scheffler, K., Stamer, E., Traulsen, I., Krieter, J.
The most recent development in pig production has focused increasingly on the well-being of the individual pig and animal-friendly housing conditions, i.e. the launch of the group housing of sows in the EU. In this regard, however, standard procedures which may be stressful to the animals and...
Behavioural testing to determine differences between coping styles in Grey parrots (Psittacus erithacus erithacus) with and without feather damaging behaviour
Contributor(s):: van Zeeland, Yvonne R. A., van der Aa, Marleen M. J. A., Vinke, Claudia M., Lumeij, Johannes T., Schoemaker, Nico J.
In various animal species, a correlation has been found between the individual's response to ‘stressing’ stimuli (coping style) in behaviour tests and the susceptibility to develop behavioural disorders. Based on analogies with feather pecking in laying hens, a similar correlation might be...
Behavioural and physiological responses of heifer calves to acute stressors: Long-term consistency and relationship with adult reactivity to milking
Contributor(s):: Van Reenen, Cornelis G., Van der Werf, Jozef T. N., O’Connell, Niamh E., Heutinck, Leonie F. M., Spoolder, Hans A. M., Jones, R. Bryan, Koolhaas, Jaap M., Blokhuis, Harry J.
The present study investigated the long-term consistency of individual differences in dairy cattles’ responses in tests of behavioural and hypothalamo–pituitary–adrenocortical (HPA) axis reactivity, as well as the relationship between responsiveness in behavioural tests and the reaction to first...
Relationship between backtest and coping styles in pigs
Contributor(s):: Spake, Jessica R., Gray, Kent A., Cassady, Joseph P.
The objective of this study was to examine relationships between behaviors in three different standard tests of temperament in pigs, Sus scrofa. For the backtest, pigs (n=575) were placed in the supine position for 60s. Each pig was tested twice. Amount of time struggling and number of struggle...
Laying hens selected for low mortality: Behaviour in tests of fearfulness, anxiety and cognition
Contributor(s):: Nordquist, Rebecca E., Heerkens, Jasper L. T., Rodenburg, T. Bas, Boks, Sabine, Ellen, Esther D., van der Staay, F. Josef
Feather pecking and cannibalism in chickens can lead to injury or to death of the victims, and is thus a serious welfare and economic issue in modern poultry farming. A sib selection scheme has been initiated to genetically select a low mortality line (LML), which shows decreased mortality due to...
Effect of short road journeys on behaviour and some blood variables related to welfare in young bulls
Contributor(s):: Cafazzo, Simona, Magnani, Diego, Calà, Pietro, Razzuoli, Elisabetta, Gerardi, Gabriele, Bernardini, Daniele, Amadori, Massimo, Costa, Leonardo Nanni
Many studies have focused on the transport of cattle to fattening farms or to slaughterhouses but there is little information concerning the transport of young bulls delivered to the genetic test stations for selection. Due to the high expected value of young AI candidate bulls, their transport...
Effect of marginal environmental and social enrichment during rearing on pigs’ reactions to novelty, conspecifics and handling
Contributor(s):: Tönepöhl, Björn, Appel, Anne K., Welp, Stephan, Voß, Barbara, König von Borstel, Uta, Gauly, Matthias
The rearing environment of farmed animals can affect their behaviour when handled, and therefore needs to be taken into account when selecting for traits such as docility. Therefore, 126 German Landrace and Pietrain×German Landrace pigs were reared in two different production environments (barren...
Effect of genetic homogeneity on behavioural variability in an object recognition test in cloned Göttingen minipigs
Contributor(s):: Søndergaard, Lene Vammen, Herskin, Mette S., Ladewig, Jan, Holm, Ida Elisabeth, Dagnæs-Hansen, Frederik
The number of animals used in research should be limited as much as possible. Among cloned animals, genetic variation is minimal and to the extent that behaviour is genetically determined inter-individual variability is expected to be higher among naturally bred animals. However, the cloning...
