Aggression and social rank fluctuations in precision-fed and skip-a-day-fed broiler breeder pullets
Contributor(s):: Girard, Teryn E., Zuidhof, Martin J., Bench, Clover J.
In broiler breeders, conventional skip-a-day feeding leads to hunger-related aggression. As an alternative, a precision feeding system was developed to provide small meals to individual birds multiple times each day, sheltered from competition. Two objectives investigated whether: 1) aggression...
To Group or Not to Group? Good Practice for Housing Male Laboratory Mice
Contributor(s):: Sarah Kappel, Penny Hawkins, Michael T. Mendl
It is widely recommended to group-house male laboratory mice because they are ‘social animals’, but male mice do not naturally share territories and aggression can be a serious welfare problem. Even without aggression, not all animals within a group will be in a state of positive...

Factors affecting feeding order and social tolerance to kittens in the group-living feral cat ( Felis catus )
Contributor(s):: Yamane, A., Emoto, J., Ota, N.
Three feeding sites on Ainoshima Island, located 7 km off the coast of Shingu (Fukuoka Prefecture) and 3 feeding groups of feral cats (Felis catus) were used in experiments conducted from 23 November to 29 December 1993 from 05.00 to 07.00 h and 16.00 to 18.00 h. Members of each feeding group...
Social order measured in pasture and pen conditions and its relationship to sexual behavior in Brahman ( Bos indicus ) cows
Contributor(s):: Orihuela, A., Galina, C. S.
The social order of 20 non-lactating, non-pregnant Brahman cows (2-6 years old) was determined by recording content and outcome of all agonistic interactions. The herd was observed at pasture for 1.5 h and in a yard for 2 h per day. This routine was undertaken every other day from 06.00 to 18.00...
Effects of a running wheel-igloo enrichment on aggression, hierarchy linearity, and stereotypy in group-housed male CD-1 (ICR) mice
Contributor(s):: Howerton, C. L., Garner, J. P., Mench, J. A.
Environmental enrichment is an important strategy to improve the welfare of laboratory animals. Running wheels might serve as enrichment devices for laboratory mice, since mice use them extensively when they are provided. However, competition among group-housed mice for such highly preferred...
Low incidence of aggression in large flocks of laying hens
Contributor(s):: Hughes, B. O., Carmichael, N. L., Walker, A. W., Grigor, P. N.
The incidence of agonistic interactions was determined in a free range system with 700 birds and in a perchery system with 10 flocks of 300 birds. In both systems aggressive behaviour and agonistic interactions were infrequent. In the perchery, when the doors between adjacent pens of 300 laying...
Epidemiology of domestic cat behavioral and welfare issues: a survey of Brazilian referral animal hospitals in 2009
Contributor(s):: Souza-Dantas, L. M. de, Soares, G. M., D'Almeida, J. M., Paixao, R. L.
Few feline behavioral categories, especially concerning their social behavior, have been studied so far. These include: the domestic cat social structure, relationships among individuals and communication among social groups. However, cats have become popular companion animals in many countries...
One ecosystem, one food system: the social and ecological context of food safety strategies
Contributor(s):: Waltner-Toews, D.
Eating is the most intimate relationship people can have with their environment. As people have migrated, in very large numbers, from various parts of the globe, as well as from the countryside to the city, they have brought to their new homes not only their intimate familial relationships, but...
Effects of separation of resources on behaviour of high-, medium- and low-ranked hens in furnished cages
| Contributor(s):: Shimmura, T., Eguchi, Y., Uetake, K., Tanaka, T.
In our previous studies, we demonstrated that dominant hens had priority in using the dust bath, resulted in increased competition for the resource. It seemed that the problem was that the resource was placed on one side of the cage ('localised'). Therefore, we designed a medium-sized...
Changes in temporal and spatial associations between pairs of cattle during the process of familiarisation
| Contributor(s):: Patison, K. P., Swain, D. L., Bishop-Hurley, G. J., Robins, G., Pattison, P., Reid, D. J.
Mixing unfamiliar individuals is a common practice in livestock production systems. However, a change in social structure can create social stresses, which can adversely affect animal welfare and reduce production. In this study, social interaction metrics were used to investigate interaction and...
High-ranking mares of captive plains zebra Equus burchelli have greater reproductive success than low-ranking mares
| Contributor(s):: Pluhacek, J., Bartos, L., Culik, L.
Plains zebra live in harems that include one to six adult mares. Between these mares is a strong order of social hierarchy. The social rank of an equid mare is typically correlated with her age. Further, high-ranking captive plains zebra mares produce more surviving offspring than low-ranking...
