This paper compares the dynamics of two local pig breeds (the Porc Blanc de l'Ouest and the Nustrale pig breeds). Those breeds are bred in contrasting territories and we demonstrate by our comparative analysis the diversity of visible stakes in the link of breeds to territories. We distinguish three categories of dissimilarities between the two cases: the first is linked to biogeographic dimension of the territory, the second to the agro-economic dimension of the territory and the last to the sociocultural aspects of the territory. We develop in the discussion an invitation to pay more attention to anchorage dynamics of local breeds in their territories.
