Investigations on feed intake and social behaviour of fattening pigs fed at an electronic feeding station
Contributor(s):: Hoy, Steffen, Schamun, Sonja, Weirich, Carmen
For the study from a total of 679 female pigs kept in a progeny test station in 64 groups mostly with 12 pigs each, the data from all visits at an electronic feeding station (EFS) were analysed. In 93 pigs (8 groups) all agonistic interactions at the EFS were recorded in continuous observations...
Feather pecking genotype and phenotype affect behavioural responses of laying hens
Contributor(s):: van der Eijk, Jerine A. J., Lammers, Aart, Li, Peiyun, Kjaer, Joergen B., Rodenburg, T. Bas
Feather pecking (FP) is a major welfare and economic issue in the egg production industry. Behavioural characteristics, such as fearfulness, have been related to FP. However, it is unknown how divergent selection on FP affects fearfulness in comparison to no selection on FP. Therefore, we...
Assessment of severity and progression of canine cognitive dysfunction syndrome using the CAnine DEmentia Scale (CADES)
Contributor(s):: Madari, A., Farbakova, J., Katina, S., Smolek, T., Novak, P., Weissova, T., Novak, M., Zilka, N.
Cognitive dysfunction syndrome (CDS) represents a group of symptoms related to the aging of the canine brain. These changes ultimately lead to a decline of memory function and learning abilities, alteration of social interaction, impairment of normal housetraining, changes in sleep-wake cycle and...

Breed differences in everyday behaviour of dogs
Contributor(s):: Asp, H. E., Fikse, W. F., Nilsson, K., Strandberg, E.
The domestication of the dog and the ensuing breed creation has resulted in a plethora of dog breeds that differ not only in morphology but also in terms of behaviour. In addition, a majority of the dogs today are no longer utilized for their working ability, but are mainly kept as companion...
Cognitive differences in horses performing locomotor versus oral stereotypic behaviour
Contributor(s):: Kirsty, R., Andrew, H., Meriel, M. C., Catherine, H.
Preliminary investigations reveal altered learning patterns in horses performing oral stereotypic behaviour which coincide with differential functioning of the basal ganglia group of brain structures. However, no studies to date have investigated similar differences in the equine locomotor...
The backtest in pigs revisited - an analysis of intra-situational behaviour
Contributor(s):: Zebunke, M., Repsilber, D., Nurnberg, G., Wittenburg, D., Puppe, B.
The occurrence of different behavioural phenotypes in animals (regarding temperament and personality) has increasingly attracted the attention of scientists dealing with farm animal breeding, management and welfare. As part of the adaptation repertoire, coping behaviour describes how animals deal...
Dominance rank is associated with body condition in outdoor-living domestic horses ( Equus caballus)
Contributor(s):: Giles, S. L., Nicol, C. J., Harris, P. A., Rands, S. A.
The aim of our study was to explore the association between dominance rank and body condition in outdoor group-living domestic horses, Equus caballus. Social interactions were recorded using a video camera during a feeding test, applied to 203 horses in 42 herds. Dominance rank was assigned to...
The power of automated behavioural homecage technologies in characterizing disease progression in laboratory mice: a review
Contributor(s):: Richardson, C. A.
Behavioural changes that occur as animals become sick have been characterized in a number of species and include the less frequent occurrence of 'luxury behaviours' such as playing, grooming and socialization. 'Sickness behaviours' or behavioural changes following exposure to infectious agents,...

Effects of phenotypic characteristics on the length of stay of dogs at two no kill animal shelters
Contributor(s):: Brown, W. P., Davidson, J. P., Zuefle, M. E.
Adoption records from 2 no kill shelters in New York State were examined to determine how age, sex, size, breed group, and coat color influenced the length of stay (LOS) of dogs at these shelters. Young puppies had the shortest length of stay; LOS among dogs increased linearly as age increased....
Genetically modified laboratory animals - what welfare problems do they face?
Contributor(s):: Buehr, M., Hjorth, P. J., Hansen, A. K., Sandoe, P.
In this article, we respond to public concern expressed about the welfare of genetically modified (GM) non-human animals. As a contribution to the debate on this subject, we attempt in this article to determine in what situations the practice of genetic modification in rodents may generate...
Phenotype characterization and welfare assessment of transgenic rodents (mice)
Contributor(s):: Mertens, C., Rulicke, T.
Methods of transgenesis in vertebrate animals in the laboratory involve the stable addition or selective substitution of defined genes into the germline. Although there is a continuous and remarkable development in transgenic technology-the quality of transgenes, gene-targeting vectors, and...
