In recent decades, several Roman Period sites, from villas to urban centres, have been studied archaeozoologically in present-day Slovenia, providing a solid understanding of the characteristics of animal husbandry in the first three centuries AD. Much less is known about the production, supply, and use of animal resources in Late Antiquity, mainly due to the meagre amount of (published) data. Of late, however, the study of a handful of contexts from the 4 th to 7 th centuries AD has provided an opportunity to gain deeper insights into the cultural changes and transformations in animal husbandry triggered by the unstable political and security conditions of the period. Among the topics addressed are how the intensity of production, the taxonomic richness of livestock, local and transregional supply systems, and the social stratification of the population changed in the turmoil of the collapsing empire. The archaeozoological results were complemented by relevant data reported by ancient authors to contextualise them better. It is suggested that late antique communities in the study area tended to be economically self-sufficient. Animal husbandry seems to have been based on relatively small specimens of primitive local forms, with the keeping of pigs and sheep gradually replacing cattle husbandry in scale.
