Headquartered in Nouakchott, in the mid-1980s the DNE operated eleven field centers in regional capitals and nineteen veterinary field stations, mostly located in the southern third of the country. Used principally in the annual vaccination campaigns, these field stations offered few other veterinary and extension services. The ministry also operated the National School for Training and Rural Extension (Ecole Nationale de Formation et Vulgarisation Rurale—ENFVR) at Kaédi, which since 1968 has trained veterinary field staff.
