This contribution discusses various aspects of animal movement as well as the dissemination of ideas in animal husbandry during Iron Age. This contribution deals with trade, appearance and spread of species or new forms. Animal movement may be transhumance, regular marketing or more exceptional importations. The emergence of new animals may be due to importations, crosses between local and external strains or new husbandry practices, breeding or feeding. Importations of animals without local strains, such as hens, peacocks, guinea fowl, cats, donkeys or mules, are easier to identify than those without local strains such as mallards, greylag geese or rock doves. Between importations, invasions and trade, motivations, circumstances and consequences of these movements are multiple and rich in interest for the history of Gaul. Therefore much remains to be done in this field.
