Comparison of Vocalization Patterns in Piglets Which Were Crushed to Those Which Underwent Human Restraint
| Contributor(s):: Nichole M. Chapel, Jeffrey R. Lucas, Scott Radcliffe, Kara R. Stewart, Donald C. Lay Jr.
: Though many studies focused on piglet crushing utilizing piglet vocalizations to test sow response, none have verified the properties of test vocalizations against actual crushing events. Ten sows were observed 48 h after parturition, and crushing events were recorded from all sows. When a...
Human Classification of Context-Related Vocalizations Emitted by Familiar And Unfamiliar Domestic Cats: An Exploratory Study
| Contributor(s):: Ellis, Sarah L. H., Swindell, Victoria, Burman, Oliver H. P.
Previous research has shown that human classification of contextspecific domestic cat “meow” vocalizations is relatively poor, although improves with experience and/or general affinity to cats. To investigate whether such classification further improves when recipients (humans) of the...
A review of behavioural methods to study emotion and mood in pigs, Sus scrofa
| Contributor(s):: Murphy, Eimear, Nordquist, Rebecca E., van der Staay, Franz Josef
The study of emotions in animals is of increasing importance to a number of disciplines such as animal welfare science and affective neuroscience. Pigs are a common farm animal species, most often reared in intensive systems. Moreover, they are increasingly being used in laboratories. To...
Nursing behaviour in lactating sows kept in isolation, in acoustic and visual contact
| Contributor(s):: Šilerová, Jitka, Špinka, Marek, Neuhauserová, Kristýna
Synchronization of nursings occurs between domestic lactating sows housed in one room. This study tested experimentally whether acoustic contact without any possibility to see other sows is sufficient for a high level of nursing synchronization. Secondly, the study investigated whether the...
Litter competition during nursings and its effect on sow response on Day 2 postpartum
| Contributor(s):: Bozděchová, Barbora, Illmann, Gudrun, Andersen, Inger Lise, Haman, Jiří, Ehrlenbruch, Rebecca
The aim of the present study was to assess neonatal sibling competition during nursing on Day 2 postpartum (pp) as well as its effect on the sow's responses. A total of 41 healthy loose-housed sows and their piglets were directly observed and video recorded for 6h on Day 2 pp. Piglet behaviours...
The efficacy of systematic desensitization for treating the separation-related problem behaviour of domestic dogs
| Contributor(s):: Butler, Rynae, Sargisson, Rebecca J., Elliffe, Douglas
The evaluation of systematic desensitization to treat separation-related problem behaviours, such as destruction of property, excessive barking, or house-soiling, has tended to rely on single case-studies. Eight dogs exhibiting separation-related behaviour, and their owners, participated in a...
Do pigs distinguish between situations of different emotional valences during anticipation?
| Contributor(s):: Imfeld-Mueller, Sabrina, Van Wezemael, Lea, Stauffacher, Markus, Gygax, Lorenz, Hillmann, Edna
An animal's welfare is strongly affected by its emotional state. Thus, many recent studies have focused on measuring the emotional states and responses of animals. However, there is still a lack of knowledge on assessing positive emotions, although it is widely accepted that positive emotions are...
Do children understand man's best friend? Classification of dog barks by pre-adolescents and adults
| Contributor(s):: Pongrácz, Péter, Molnár, Csaba, Dóka, Antal, Miklósi, Ádám
Play back experiments compared the ability of children (aged 6, 8, and 10 years) and adults to discriminate dog barks recorded in three different contexts. Participants had to categorize barks according to recording context, and to characterize the inner states of dogs by relating barks to facial...
Degree of social isolation affects behavioural and vocal response patterns in dwarf goats (Capra hircus)
| Contributor(s):: Siebert, Katrin, Langbein, Jan, Schön, Peter-Christian, Tuchscherer, Armin, Puppe, Birger
Separation from the group presents a serious challenge for social animals. This stressful and disagreeable situation can impair animal welfare and may have an undesirable impact on experimental data in scientific studies. In the present study, we observed whether different degrees of social...
Behavioural fear and heart rate responses of horses after exposure to novel objects: Effects of habituation
| Contributor(s):: Leiner, Lisa, Fendt, Markus
The emotion fear promotes the fitness of wild animals. In a farm environment, exaggerated fear, e.g., in horses, can cause several problems. Therefore, knowledge about fear in horses helps to prevent or to handle potential fear-inducing situations. The present study investigated which behavioural...
Early recognition of offspring vocalisation by mink mothers
| Contributor(s):: Malmkvist, Jens
Mink deliver around the same time of year. Consequently, mink dams are exposed to other delivering dams and litters nearby in the same housing facility on farms. In addition, farmers often transfer kits between litters within the first week of life, as levelling large litters is believed to...
Maternal nest building and choice of nest site are temperature dependent in mink: Parent-offspring temperature conflict?
| Contributor(s):: Schou, Toke Munk, Malmkvist, Jens
We investigated whether nest building and nest site preference are temperature dependent in female mink. We designed two experiments: in Experiment 1, female mink had access to unheated (7 °C, Room7C group) or heated (25 °C, Heated25C group) nest boxes; in Experiment 2, female mink had free...
Should I whine or should I bark? Qualitative and quantitative differences between the vocalizations of dogs with and without separation-related symptoms
| Contributor(s):: Pongrácz, Péter, Lenkei, Rita, Marx, András, Faragó, Tamás
Separation-related disorder (SRD) is one of the most common behavioral problems of companion dogs, causing inconvenience and stress for dog owners and others living close by, as well as being considered as a major contributor to poor animal welfare. Although excessive vocalization is considered...
Cats and owners interact more with each other after a longer duration of separation
| Contributor(s):: Matilda Eriksson, Linda J. Keeling, Therese Rehn
Little is known about the cat’s (Felis silvestris catus) need for human contact, although it is generally believed that cats are more independent pets than e.g. dogs. In this study, we investigated the effect of time left alone at home on cat behaviour (e.g. social and distress-related)...

Cheetahs discriminate familiar and unfamiliar human voices
| Contributor(s):: Maël Leroux, Robyn Shelia Hetem, Martine Hausberger, Alban Lemasson
Domestic species can make the distinction between several human sub-groups, especially between familiar and unfamiliar persons. The Domestication hypothesis assumes that such advanced cognitive skills were driven by domestication itself. However, such capacities have been shown in wild species...

Pet dog management practices among a representative sample of owners in Victoria, Australia
| Contributor(s):: Howell, T. J., Mornement, K., Bennett, P. C.
It is often assumed that pet dogs experience better welfare than livestock production animals because many owners consider them to be members of the family and, collectively, spend billions of dollars on them annually. However, this assumption is not based on scientific evidence, and a...
Examining dog-human play: the characteristics, affect, and vocalizations of a unique interspecific interaction
| Contributor(s):: Horowitz, A., Hecht, J.
Despite the growing interest in research on the interaction between humans and dogs, only a very few research projects focus on the routines between dogs and their owners. In this study, we investigated one such routine: dog-human play. Dyadic interspecific play is known to be a common...
