Social space in farm animals was the subject of the semi- nar held in Brussels, on January 10 - 11, 1985, at the Commis- sion of the European Communities (C. E. C. ), Directorate General for Agriculture. As part of the work of the Division for the Coordination of Agricultural Research, the seminar was organi- zed in the context of the various problems bearing relevance to animal welfare. Also, one of its main purports was to pre- sent experimental results which were obtained in various labo- ratories working in a CEC research programme on social space, particularly on the spatial requirements of laying hens in battery cages. These results are presented in section II of the proceedings, and section III offers similar results in other domestic animals such as pigs, dairy cows, and sheep. These contributions have focused on the problems raised by density, selected as a major variable among those present in current farm animal housing. In contrast to other books devoted to wel- fare and stress of farm livestock, the present one emphasizes the relation between spatial measures (group size and floor area per animal) and social behaviour or social structure in domestic animals.
The second objective of the seminar was to provide and discuss available information from experiments on social space in laboratory species and in domestic animals observed in non intensive environments.
